This enables device operation in a pure IPv6 network as well as in a combined IPv4/IPv6 network. For more information, see "IP Addressing" on page 209. Stack Support The system supports up to eight units with two fixed HDMI stacking ports. The HDMI ports are 1.3a specification, Category 2 High Speed cables, 340 MHz (10.2 Gbit/s). it is recommended to use HDMI cable version 1.4 The stacking feature supports the following features: • Fast-link failover • Software auto-synch. • Improved response time to events, such as master failover • Auto-numbering algorithm when choosing unit number For more information, see "Stacking Overview" on page 45 Power over Ethernet Power over Ethernet (PoE) provides power to devices over existing LAN cabling, without updating or modifying the network infrastructure. When PoE is used, the network devices do not have to be placed next to a power source. PoE can be used in the following applications: • IP Phones • Wireless Access PointsDell PowerConnect 55xx Systems User Guide 17 FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxUGFeatures.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY • IP Gateways • PDAs • Audio and video remote monitoring For more information, see "Power over Ethernet" on page 162. Green Ethernet Green Ethernet, also known as Energy Efficient Ethernet (EEE), is an effort to make networking equipment environmentally friendly, by reducing the power usage of Ethernet connections. The Short-Reach method, which reduces power over Ethernet cables shorter than 40m, is supported by the device. For more information, see "Green Ethernet Configuration" on page 390. Head of Line Blocking Prevention Head of Line (HOL) blocking results in traffic delays and frame loss caused by traffic competing for the same egress port resources. To prevent HOL blocking, the device queues packets, and packets at the head of the queue are forwarded before packets at the end of the queue. Flow Control Support (IEEE 802.3X) Flow control enables lower-speed devices to communicate with higher-speed devices, by requesting that the higher-speed device refrain from sending packets. Transmissions are temporarily halted to prevent buffer overflows. For more information, see "Flow Control" on page 386. Back Pressure Support On half-duplex links, the receiving port prevents buffer overflows by occupying the link so that it is unavailable for additional traffic. For more information, see "Protected Ports" on page 394.18 Dell PowerConnect 55xx Systems User Guide FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxUGFeatures.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY Virtual Cable Testing (VCT) VCTdetects and reports copper link cabling faults, such as open cables and cable shorts. For more information, see "Diagnostics" on page 255. Auto-Negotiation Auto-negotiation enables the device to advertise modes of operation. The auto-negotiation function enables an exchange of information between two devices that share a point-to-point link segment, and automatically configures both devices to take maximum advantage of their transmission capabilities. The PowerConnect 5500 series enhances auto-negotiation by providing port advertisement. Port advertisement enables the system administrator to configure the port speeds that are advertised. For more information, see "Port Configuration" on page 403 or "LAG Configuration" on page 409. MDI/MDIX Support Standard wiring for end stations is known as Media-Dependent Interface (MDI), and standard wiring for hubs and switches is known as MediaDependent Interface with Crossover (MDIX). If auto-negotiation is enabled, the device automatically detects whether the cable connected to an RJ-45 port is MDIX (crossed) or MDI (straight). This enables both types to be used interchangeably. If auto-negotiation is not enabled, only MDI (straight) cables can be used. For more information, see "Port Configuration" on page 403 or "LAG Configuration" on page 409. MAC Address Supported Features MAC Address Capacity Support The device supports up to 16K MAC addresses and it reserves specific MAC addresses for system use.Dell PowerConnect 55xx Systems User Guide 19 FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxUGFeatures.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY Static MAC Entries MAC entries can be manually entered in the Bridging Table, as an alternative to learning them from incoming frames. These user-defined entries are not subject to aging, and are preserved across resets and reboots. For more information, see "Static Addresses" on page 424. Self-Learning MAC Addresses The device enables controlled MAC address learning from incoming packets. The MAC addresses are stored in the Bridging Table. For more information, see "Dynamic Addresses" on page 427. Automatic Aging for MAC Addresses MAC addresses from which no traffic is received for a given period, are aged out. This prevents the Bridging Table from overflowing. For more information, see "Dynamic Addresses" on page 427. VLAN-Aware MAC-Based Switching The device always performs VLAN-aware bridging. Classic bridging (IEEE802.1D), in which frames are forwarded based only on their destination MAC address, is not performed. However, a similar functionality can be configured for untagged frames. Frames addressed to a destination MAC address that is not associated with any port are flooded to all ports of the relevant VLAN. MAC Multicast Support Multicast service is a limited Broadcast service that enables one-to-many and many-to-many connections for information distribution. In Layer 2 Multicast service, a single frame is addressed to a specific Multicast address, from which copies of the frame are transmitted to the relevant ports. When Multicast groups are statically enabled, you can set the destination port of registered groups, as well as define the behavior of unregistered Multicast frames. For more information, see "Multicast" on page 516.20 Dell PowerConnect 55xx Systems User Guide FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxUGFeatures.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY Layer 2 Features IGMP Snooping Internet Group Membership Protocol (IGMP) Snooping examines IGMP frame contents, when they are forwarded by the device from work stations to an upstream Multicast router. From the frame, the device identifies work stations configured for Multicast sessions, and which Multicast routers are sending Multicast frames. The IGMP Querier simulates the behavior of a Multicast router. This enables snooping of the Layer 2 Multicast domain even if there is no Multicast router. For more information, see "IGMP Snooping" on page 527. Port Mirroring Port mirroring monitors network traffic by forwarding copies of incoming and outgoing packets from a monitored port to a monitoring port. Users specify which target port receives copies of all traffic passing through a specified source port. For more information, see "Port Mirroring" on page 417. Broadcast Storm Control Storm Control enables limiting the number of Multicast and Broadcast frames accepted by and forwarded by the device. When Layer 2 frames are forwarded, Broadcast and Multicast frames are flooded to all ports on the relevant VLAN. This occupies bandwidth, and loads all nodes connected on all ports. For more information, see "Storm Control" on page 414.Dell PowerConnect 55xx Systems User Guide 21 FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxUGFeatures.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY VLAN Supported Features VLAN Support VLANs are collections of switching ports that comprise a single Broadcast domain. Packets are classified as belonging to a VLAN, based on either the VLAN tag or on a combination of the ingress port and packet contents. Packets sharing common attributes can be grouped in the same VLAN. For more information, see "VLANs" on page 466. Port-Based Virtual LANs (VLANs) Port-based VLANs classify incoming packets to VLANs, based on their ingress port. For more information, see "Defining VLAN Membership Using CLI Commands" on page 473. Full 802.1Q VLAN Tagging Compliance IEEE 802.1Q defines an architecture for virtual, bridged LANs, the services provided in VLANs, and the protocols and algorithms involved in the provision of these services. For more information, see "Virtual LAN Overview" on page 467. GVRP Support GARP VLAN Registration Protocol(GVRP) provides IEEE 802.1Qcompliant VLAN pruning and dynamic VLAN creation. When GVRP is enabled, the device registers and propagates VLAN membership on all ports that are part of the active underlying Spanning Tree Protocol topology. For more information, see "GVRP Parameters" on page 490. Voice VLAN Voice VLAN enables network administrators to enhance VoIP service by configuring ports to carry IP voice traffic from IP phones on a specific VLAN. VoIP traffic has a preconfigured OUI prefix in the source MAC address. Network administrators can configure VLANs from which voice IP traffic is 22 Dell PowerConnect 55xx Systems User Guide FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxUGFeatures.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY forwarded. Non-VoIP traffic is dropped from the Voice VLAN in Auto-Voice VLAN Secure mode. Voice VLAN also provides QoS to VoIP, ensuring that the quality of voice does not deteriorate if the IP traffic is received unevenly. For more information, see "Voice VLAN" on page 498. Guest VLAN Guest VLAN provides limited network access to unauthorized ports. If a port is denied network access via port-based authorization, but the Guest VLAN is enabled, the port receives limited network access through the Guest VLAN. For more information, see "Dot1x Authentication" on page 132. Private VLAN The Private VLAN feature provides Layer 2 isolation between ports that share the same Broadcast domain, or in other words, it creates a point-tomultipoint Broadcast domain. The ports can be located anywhere in the Layer 2 network (compared to the Protected Ports feature, where the ports must be in the same stack). For more information, see "Private VLAN" on page 494. Multicast TV VLAN The Multicast TV VLAN feature provides the ability to supply multicast transmissions to Layer 2-isolated subscribers, without replicating the multicast transmissions for each subscriber VLAN. The subscribers are the only receivers of the multicast transmissions. For more information, see "Multicast TV VLAN" on page 535. Spanning Tree Protocol Features Spanning Tree Protocol (STP) 802.1d Spanning tree is a standard Layer 2 switch requirement that enables bridges to automatically prevent and resolve Layer 2 forwarding loops. Switches exchange configuration messages using specifically-formatted frames, and selectively enable and disable forwarding on ports. For more information, see "Spanning Tree" on page 434. Dell PowerConnect 55xx Systems User Guide 23 FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxUGFeatures.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY Fast Link STP can take 30–60 seconds to converge. During this time, STP detects possible loops, enabling time for status changes to propagate and for relevant devices to respond. This period of 30-60 seconds is considered too long a response time for many applications. The Fast Link option bypasses this delay, and can be used in network topologies, where forwarding loops do not occur. For more information on enabling Fast Link for ports and LAGs, see "STP Port Settings" on page 442 or "Static Addresses" on page 424. IEEE 802.1w Rapid Spanning Tree Spanning Tree takes 30–60 seconds for each host to decide whether its ports are actively forwarding traffic. Rapid Spanning Tree (RSTP) detects uses of network topologies to enable faster convergence, without creating forwarding loops. For more information, see "Spanning Tree" on page 434. IEEE 802.1s Multiple Spanning Tree Multiple Spanning Tree (MSTP) operation maps VLANs into STP instances. MSTP provides a different load balancing scenario. Packets assigned to various VLANs are transmitted along different paths within MSTP Regions (MST Regions). Regions are one or more MSTP bridges by which frames can be transmitted. The standard lets administrators assign VLAN traffic to unique paths. For more information, see "Spanning Tree" on page 434. STP BPDU Guard BPDU Guard is used as a security mechanism, to protect the network from invalid configurations. BPDU Guard is usually used either when fast link ports (ports connected to clients) are enabled or when the STP feature is disabled. When it is enabled on a port, the port is shut down if a BPDU message is received and an appropriate SNMP trap is generated. For more information, see "Spanning Tree" on page 434.24 Dell PowerConnect 55xx Systems User Guide FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxUGFeatures.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY Link Aggregation Up to 32 Aggregated Links may be defined, each with up to eight member ports, to form a single Link Aggregated Group (LAG). This enables: • Fault tolerance protection from physical link disruption • Higher bandwidth connections • Improved bandwidth granularity • High bandwidth server connectivity A LAG is composed of ports with the same speed, set to full-duplex operation. For more information, see "LAG Configuration" on page 409. Link Aggregation and LACP LACP uses peer exchanges across links to determine, on an ongoing basis, the aggregation capability of various links, and continuously provides the maximum level of aggregation capability achievable between a given pair of devices. LACP automatically determines, configures, binds, and monitors the port binding within the system. For more information, see "Link Aggregation" on page 508. BootP and DHCP Clients DHCP enables additional setup parameters to be received from a network server upon system startup. DHCP service is an on-going process. DHCP is an extension of BootP. For more information, see "DHCP IPv4 Interface" on page 214. Quality of Service Features Class of Service 802.1p Support The IEEE 802.1p signaling technique is an OSI Layer 2 standard for marking and prioritizing network traffic at the data link/MAC sub-layer. 802.1p traffic is classified and sent to the destination. No bandwidth reservations or limits Dell PowerConnect 55xx Systems User Guide 25 FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxUGFeatures.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY are established or enforced. 802.1p is a spin-off of the 802.1Q (VLANs) standard. 802.1p establishes eight levels of priority, similar to the IP Precedence IP Header bit-field. Advanced QoS Frames that match an ACL and were permitted entrance are implicitly labeled with the name of the ACL that permitted their entrance. Advanced mode QoS actions defined in network policies can then be applied to these flows. The switch can set DSCP values and map IPv6 DSCP to egress queues in the same way it does for IPv4. The switch detects IPv6 frames by the IPv6 ethertype. For more information about Advanced QoS, see "QoS Advanced Mode" on page 678. TCP Congestion Avoidance The TCP Congestion Avoidance feature activates an algorithm that breaks up or prevents TCP global synchronization on a congested node, where the congestion is due to multiple sources sending packets with the same byte count. For more information, see "The following is an example of the CLI commands:" on page 666. Device Management Features SNMP Alarms and Trap Logs The system logs events with severity codes and timestamps. Events are sent as SNMP traps to a Trap Recipient List. For more information, see "SNMP" on page 314.26 Dell PowerConnect 55xx Systems User Guide FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxUGFeatures.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY SNMP Versions 1, 2, and 3 Simple Network Management Protocol (SNMP) over the UDP/IP protocol controls access to the system. A list of community entries is defined, each consisting of a community string and its access privileges. There are three levels of SNMP security: read-only, read-write, and super. Only a super user can access the Community table. For more information, see "SNMP" on page 314. Web-Based Management Web-based management enables managing the system from any web browser. The system contains an Embedded Web Server (EWS) that serves HTML pages, through which the system can be monitored and configured. The system internally converts web-based input into configuration commands, MIB variable settings, and other management-related settings. Management IP Address Conflict Notification This feature validates the uniqueness of the switch's IP address, whether it is assigned manually or through DHCP. If the IP address is not unique, the switch performs actions according to the address type. If the IP address is static, see more information about this in "IPv4 Interface Parameters" on page 210. If the IP address is dynamic, see more information about this in"DHCP IPv4 Interface" on page 214. Flow Monitoring (sflow) The switch supports statistics collection, using a sampling technology called sFlow that is based on RFC 3176. The sFlow sampling technology is embedded within the switch, and provides the ability to continuously monitor traffic flows on some or all the interfaces simultaneously. For more information, see "sFlow" on page 375. Configuration File Download and Upload The device configuration is stored in a configuration file. The configuration file includes both system-wide and port-specific device configuration. The system can display configuration files as a collection of CLI commands that are stored and manipulated as text files.Dell PowerConnect 55xx Systems User Guide 27 FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxUGFeatures.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY Auto-Update of Configuration/Image File This feature facilitates installation of new devices. When you enable the various auto-update options, the device automatically downloads a new image or configuration file when it receives its IP address from a TFTP server, and automatically reboots, using the image or configuration file it received. For more information, see "Auto-Update/Configuration Feature" on page 338. TFTP Trivial File Transfer Protocol The device supports boot image, software, and configuration upload/download via TFTP. USB File Transfer Protocol The device supports boot image, software, and configuration upload/download via USB. Remote Monitoring Remote Monitoring (RMON) is an extension to SNMP that provides comprehensive network traffic monitoring capabilities. RMON is a standard MIB that defines MAC-layer statistics and control objects, enabling real-time information to be captured across the entire network. For more information, see "Statistics/RMON" on page 606. Command Line Interface Command Line Interface (CLI) syntax and semantics conform as much as possible to common, industry standards. CLI is composed of mandatory and optional elements. The CLI interpreter provides command and keyword completion to assist users and save typing. Syslog Syslog is a protocol that enables event notifications to be sent to a set of remote servers, where they can be stored, examined, and acted upon. The system sends notifications of significant events in real time, and keeps a record of these events for after-the-fact usage.

Time synchronization is performed by a network SNTP server. Time sources are prioritized by strata. Strata define the distance from the reference clock. The higher the stratum (where zero is the highest), the more accurate the clock. For more information, see "Time Synchronization" on page 169. Domain Name System Domain Name System (DNS) converts user-defined domain names into IP addresses. Each time a domain name is assigned, the DNS service translates the name into a numeric IP address. For example, www.ipexample.com is translated into 192.87.56.2. DNS servers maintain domain name databases containing their corresponding IP addresses. For more information, see "Domain Name System" on page 242. 802.1ab (LLDP-MED) The Link Layer Discovery Protocol (LLDP) enables network managers to troubleshoot, and enhances network management by discovering and maintaining network topologies over multi-vendor environments. LLDP discovers network neighbors by standardizing methods for network devices to advertise themselves to other systems, and to store discovered information. The multiple advertisement sets are sent in the packet Type Length Value (TLV) field. LLDP devices must support chassis and port ID advertisement, as well as system name, system ID, system description, and system capability advertisements. LLDP Media Endpoint Discovery (LLDP-MED) increases network flexibility by enabling various IP systems to co-exist on a single network LLDP. It provides detailed network topology information, emergency call service via IP phone location information, and troubleshooting information. For more information, see "LLDP" on page 540.Dell PowerConnect 55xx Systems User Guide 29 FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxUGFeatures.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY Security Features SSL Secure Socket Layer (SSL) is an application-level protocol that enables secure transactions of data through privacy, authentication, and data integrity. It relies upon certificates and public and private keys. Port-Based Authentication (Dot1x) Port-based authentication enables authenticating system users on a per-port basis via an external server. Only authenticated and approved system users can transmit and receive data. Ports are authenticated via the Remote Authentication Dial-In User Service (RADIUS) server using the Extensible Authentication Protocol (EAP). Dynamic VLAN Assignment (DVA) enables network administrators to automatically assign users to VLANs during the RADIUS server authentication. For more information, see "Dot1x Authentication" on page 132. Locked Port Support Locked Port increases network security by limiting access on a specific port to users with specific MAC addresses. These addresses are either manually defined or learned on that port. When a frame is seen on a locked port, and the frame source MAC address is not tied to that port, the protection mechanism is invoked. For more information, see "Port Security" on page 98. RADIUS Client RADIUS is a client/server-based protocol. A RADIUS server maintains a user database that contains per-user authentication information, such as user name, password, and accounting information. RADIUS Accounting This feature enables recording device management sessions (Telnet, serial, and WEB but not SNMP) and/or 802.1x authentication sessions.30 Dell PowerConnect 55xx Systems User Guide FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxUGFeatures.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY Due to the complexity of 802.1x setup and configuration, many mistakes can be made that might cause loss of connectivity or incorrect behavior. The 802.1x Monitor mode enables applying 802.1x functionality to the switch, with all necessary RADIUS and/or domain servers active, without actually taking any action that may cause unexpected behavior. In this way, the user can test the 802.1x setup before actually applying it. For more information, see "RADIUS" on page 291. SSH Secure Shell (SSH) is a protocol that provides a secure, remote connection to a device. SSH version 2 is currently supported. The SSH server feature enables an SSH client to establish a secure, encrypted connection with a device. This connection provides functionality that is similar to an inbound telnet connection. SSH uses RSA and DSA Public Key cryptography for device connections and authentication. For more information, see "Security Management and Password Configuration" on page 75. TACACS+ TACACS+ provides centralized security for validation of users accessing the device. TACACS+ provides a centralized, user management system, while still retaining consistency with RADIUS and other authentication processes. For more information, see "TACACS+" on page 282. Password Management Password management provides increased network security and improved password control. Passwords for SSH, Telnet, HTTP, HTTPS, and SNMP access are assigned security features. For more information, see "Password Management" on page 286. The switch provides the ability to demand strong passwords, meaning that they must contain both upper and lower-case letters, numbers, and punctuation marks.

Packets entering an ingress port with an active ACL, are either admitted or denied entry and the ingress port is disabled. If they are denied entry, the user can disable the port. Dynamic ACL/Dynamic Policy Assignment (DACL/DPA) The network administrator can specify the user's ACL in the RADIUS server. After successful authentication, the user is assigned that ACL. For more information, see "Network Security" on page 97. DHCP Snooping DHCP Snooping expands network security by providing firewall security between untrusted interfaces and DHCP servers. By enabling DHCP Snooping, network administrators can differentiate between trusted interfaces connected to end-users or DHCP servers and untrusted interfaces located beyond the network firewall. For more information, see "DHCP Snooping" on page 573. ARP Inspection Dynamic ARP inspection is a security feature that validates ARP packets in a network. It intercepts, logs, and discards ARP packets with invalid IP-to-MAC address bindings. This capability protects the network from certain man-inthe-middle attacks. Port Profile (CLI Macro) Macros provide a convenient way to save and share a common configuration. A macro is a set of CLI commands with a unique name. When a macro is applied to a port, the CLI commands contained within it are executed and added to the Running Configuration file.

The switch can serve as a DHCP server or client. For more information on the device serving as a DHCP server, see "DHCP Server" on page 297. For more information on the device serving as a DHCP client, see "DHCP IPv4 Interface" on page 214. Protected Ports The Protected Ports feature provides Layer 2 isolation between interfaces (Ethernet ports and LAGs) that share the same Broadcast domain (VLAN) with other interfaces. For more information, see "Protected Ports" on page 394. iSCSI Optimization iSCSI optimization provides the iSCSI flows with specific priority over other network traffic. In addition, the feature provides monitoring of iSCSI sessions. For more information, see "iSCSI Optimization" on page 594. Proprietary Protocol Filtering This feature enables user control over the filtering of packets with proprietary protocols such as CDP, VTP, DTP, UDLD, PaGP, and SSTP. The user can select any combination of the protocols to be filtered, for example: CDP and VTP and UDLD. For more information, see "Network Security" on page 97. DHCP Relay and Option 82 A DHCP relay agent detects DHCP Broadcasts from DHCP clients and relays them to DHCP servers that may reside on different subnets.Dell PowerConnect 55xx Systems User Guide 33 FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxUGFeatures.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY The relay agent information option (Option 82) in the DHCP protocol enables a DHCP relay agent to send additional client information, upon requesting an IP address.

It contains the following topics: • Stack Overview • Stack Members and Unit IDs46 Dell PowerConnect 55xx Systems User Guide FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxUGStacking.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY Stack Overview The PowerConnect 5500 Stacking feature provides multiple switch management through a single switch, so that all units in the stack are treated as if they were a single switch. All stack members are accessed through the management IP address, through which the stack is managed. Each switch is a member in a stack, although the stack may consist of only a single switch. Up to eight units can be stacked. This section covers the following topics: • Stack Operation Modes • Stacking Units • Stack Topology Stack Operation Modes All stacks must have a Master unit, and may have a Master Backup unit. All other units are connected to the stack as members (slaves). A unit in the stack can be in one of the following modes: • Stack Master — Runs the fully operational software of a switch. In addition, it runs configures and manages all other units in the stack. All protocols run in the context of the Master unit. It is responsible for updating and synchronizing the Master Backup. The Stack Master detects and reconfigures the ports with minimal operational impact in the event of: Unit failure Inter-unit stacking link failure Unit insertion Unit removal When the Master unit boots, or when inserting or removing a stack member, the Master unit initiates a stacking discovering process. Dell PowerConnect 55xx Systems User Guide 47 FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxUGStacking.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY • Slave Unit — Runs a slave version of the software that enables the applications running on the Master’s CPU to control and manage the resources of the slave unit. • Master Backup — Runs as a slave unit, as described above, and in addition, continuously monitors the existence and operation of the stack master. If the master unit fails, the master-backup unit assumes the Master Backup role. Stacking Units PowerConnect 5500 series switches use two HDMI 10G ports for stacking. To connect the units in the stack: 1 Insert one end of an HDMI cable into the left-hand HDMI port on the unit at the top of the stack and the other end into the right-hand HDMI port of the unit immediately below it (this is called crossover). 2 Repeat this process until all units are connected. 3 (Optional) Connect the left-hand HDMI port of the unit at the bottom of the stack to the right-hand HDMI port of the unit at the top of the stack. This step provides increased bandwidth and redundancy.48 Dell PowerConnect 55xx Systems User Guide FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxUGStacking.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY The results of this process are shown in Figure .

Ring Topology In a ring topology all units in the stack are connected to each other, forming a circle. Each unit in the stack accepts data and sends it to the unit to which it is attached. The packet continues through the stack until it reaches its destination. The system discovers the optimal path on which to send traffic. Figure 4-1 shows units of a stack connected in a ring topology. Stacking Failover Topology - Chain Topology Difficulties occur when a unit in the ring becomes non-functional, or a link is severed. In this case, the system automatically switches to a chain topology, without any system downtime. In chain topology, each unit in the stack is connected to neighboring unit except for the last unit, which is not connected to any other unit. In the chain topology, the stack continues to function as long as there is a master- or backup-enabled unit in each segment of the stack. When the ring topology is switched to chain topology, an SNMP message is automatically generated, but no stack management action is required. The unit that failed must be repaired to restore full stacking operation in the ring topology. After the stacking issues are resolved, the units can be reconnected without interruption, and the ring topology is restored. Stack Members and Unit IDs This section describes how to configure the stack. It contains the following topics: • Adding a Unit to the Stack • Assigning Unit IDs • Selecting the Master and Master Backup Units • Switching from the Master to the Master Backup • Replacing Stacking Members50 Dell PowerConnect 55xx Systems User Guide FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxUGStacking.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY • Loading Software onto Stack Members • Rebooting the Stack • Managing Configuration Files on the Stack Adding a Unit to the Stack The recommended procedure to add a unit to a stack is as follows: 1 Place the powered-off unit in its physical place in the stack, and insert the stacking link in the unit (but do not connect it to the rest of the stack). 2 Power up the unit, and set the correct Unit ID, as described below. 3 Reboot the unit and connect it to the rest of the stack through the stack link. Assigning Unit IDs Each unit in the stack has a unique ID that defines the unit’s position and function in the stack, as shown in Figure 3-2. The unit that is assigned Unit ID 1 is the Master unit, by default. The unit that is assigned Unit ID 2 is the Master Backup unit. When you power-up the stack, each unit is assigned a unique Unit ID. This is displayed on the front panel of the unit, as shown in Figure 3-2. The Unit ID of each unit can be either automatically assigned or manually assigned, as described in step 1 to step 4 below. To assign IDs to the units in the stack, do the following for each unit in the stack: 1 Connect the unit to the terminal.Dell PowerConnect 55xx Systems User Guide 51 FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxUGStacking.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY 2 Turn on the unit to begin auto boot and press Return or Esc to abort and enter the Start Up menu. 3 Select Stack Menu to open the Stack Menu. 4 Select Set Unit Stack ID. Enter either a Unit ID for manual assignment or 0 to indicate that the unit ID will be assigned automatically. NOTE: The entire stack should be connected, as shown in Figure 4-1, before powering up the units. Selecting the Master and Master Backup Units A unit is master-enabled if it assigned Unit ID 1 and Unit 2. All other units in the stack (slaves) have unit IDs of 3-8. The stack master assignment is performed during the configuration boot process. One master-enabled stack member is elected as Master, and the other master-enabled stack member is selected as Master Backup, according to the following decision process: • A master is selected from the set of the two Master-enabled units. Priority is given to the lowest unit ID, but also takes into account the amount of time the unit is UP (Up Time) as follows: Startup Menu [1]Download Software [2]Erase Flash File [3]Password Recovery Procedure [4]Set Terminal Baud-Rate [5]Stack Menu [6]Back [1]Show Unit Stack ID [2]Set Unit Stack ID [3]Back52 Dell PowerConnect 55xx Systems User Guide FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxUGStacking.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY – When a master-enabled unit is inserted to a running stack, (or when Master and Backup master both start at the same time), they exchange each other’s UP TIME (the time since they powered up). If the time difference is smaller than 10 minutes, the unit with the lowest unit ID is elected; otherwise, the unit with the longest UP time is elected. – If a Master-enabled unit (with ID 1 or 2) is inserted into an operational stack, it will be elected as a backup master. – If a Master unit and/or a backup Master unit is removed from the stack and the user wishes to configure one of the slave units (numbered 3-8) to be a Master backup, the user must reset the unit’s ID. This can be done as follows: • If there is a Master-enabled unit in the stack: Do -switch n renumber 2 (through CLI or GUI). This makes the nth unit a master-enabled unit. • If there is no Master-enabled unit in the stack: Press the reset button on the unit to be master-enabled, and assign it a unit ID= 1 using the boot menu. • The user can force a master-enabled unit to be the master unit of the stack, even if the master election process did not select it. This is done by switching over to the backup unit. NOTE: Two stacking member are considered the same age if they were inserted within a ten minute interval, for example, if Unit 2 is inserted in the first minute of a ten-minute cycle, and Unit 1 is inserted in fifth minute of the same cycle, the units are considered to be the same age. NOTE: If two stack members are discovered to have the same Unit ID, only the older unit is included in the stack. The stack continues to function and a message is sent notifying that a unit failed to join the stack. The Stack Master and the Master Backup maintain a Warm Standby. The Warm Standby ensures that the Master Backup takes over for the Stack Master if a failover occurs, so that the stack continues to operate normally. During the Warm Standby, the Master and the Master Backup are synchronized with the static configuration. When the Stacking Master is configured, it must synchronize the Master Backup.

Switching from the Master to the Master Backup The Master Backup replaces the Stack Master if one or more of the following events occur: • The Stack Master fails or is removed from the stack. • Links from the Stack Master to the stacking members fails. • User performs soft switchover via the Web interface or the CLI. Switching between the Stack Master and the Master Backup results in limited service loss. Dynamic tables are relearned if a failure occurs. The Running Configuration file is synchronized between Stack Master and the Master Backup, and continues running on the Master Backup. Replacing Stacking Members If a unit is removed from the stack, and replaced with a unit with the same unit ID, the stack member is configured with the original unit configuration. Otherwise, if the new unit has either more or fewer ports than the previous unit, the results depend on the device type of the new and original units, as defined in Table 4-1: Table 4-1.

If software is only loaded to the master unit, when new software is selected, and the Master is rebooted, the Master updates the software on the remaining units. In this way, all units in the stack run the same software version. Rebooting the Stack Whenever a reboot occurs, topology discovery is performed, and the Master learns all units IDs in the stack. Configuration files are changed only through explicit user configuration, and are not automatically modified when units are added, removed or reassigned unit IDs. Each time the system reboots, the Startup Configuration file in the Master unit is used to configure the stack. Managing Configuration Files on the Stack The Startup Configuration and Running Configuration file are stored on the stack master. Each port in the stack is referenced in the configuration files by its port type and unit ID/0/port number, for example "gi1/0/24", which means Giga port 24 on unit 1 (the middle 0 is reserved for future use). Configuration files are managed from the Stack Master, including: • Saving to flash memory 5524P or 5524 5548P or 5548 The PowerConnect 5524/P 24 Gigabit ports receives the first 24 Giga 5548/P port configurations.

The switch then goes through power-on self-test (POST). POST runs every time the switch is started and checks hardware components, to determine if the switch is operational before completely booting. If the system detects a critical problem, the boot process stops. If POST passes successfully, a valid executable image is loaded into RAM. POST messages are displayed on the terminal and indicate test success or failure. The boot process runs for approximately 40-45seconds. When the boot process completes, the following LEDs are lit, as shown in Figure 5-2: • Power • Status • Fan (should be green) • RPS (if it is being used) Figure 5-2.

If there is more than one switch in the stack, each switch must be configured individually. See "Assigning Unit IDs" on page 50 for instructions on how to configure the stack. Configuration Using the Setup Wizard The Setup Wizard guides you through the initial switch configuration to get the system up and running as quickly as possible. Note that you can skip the Setup Wizard and configure the switch manually through the CLI. The Setup Wizard configures the following fields: • SNMP Community String and SNMP Management System IP address (optional) • Username and password • Management switch IP address • IP subnet mask • Default gateway IP address NOTE: The Setup Wizard assumes the following: • The PowerConnect switch was never configured before and is in the same state as when you received it. • The PowerConnect switch booted successfully. • The console connection is established and the console prompt is displayed on the screen of a VT100 terminal switch. Connect the Master unit to a terminal. You can identify the Master unit by the illuminated Master LED on the front panel of the switch (see Figure 3-2).

For a complete description of CLI commands, refer to the Dell PowerConnect 55xx Systems CLI Reference Guide. Command Mode Overview The CLI is divided into command modes, each with a specific command set. Entering a question mark at the terminal prompt displays a list of commands available for that particular command mode. In each mode, a specific command is used to navigate from one mode to another. These modes are described below. User EXEC Mode During CLI session initialization, the CLI is in User EXEC mode. Only a limited subset of commands is available in User EXEC mode. This level is reserved for tasks that do not change the terminal configuration and is used to access configuration sub-systems. After logging into the device, User EXEC command mode is enabled. The user-level prompt consists of the host name followed by the angle bracket (>). For example: console> NOTE: The default host name is console unless it has been modified during initial configuration. The User EXEC commands enable connecting to remote devices, changing terminal settings on a temporary basis, performing basic tests, and listing system information. To list the User EXEC commands, enter a question mark at the command prompt. To enter the next level, Privileged EXEC mode, a password is required (if configured). Privileged EXEC Mode Privileged EXEC mode provides access to the device global configuration.

Passwords are displayed on the screen, and are case-sensitive. NOTE: The enable command is only necessary if you login with privilege level less than 15. To access and list the Privileged EXEC mode commands: 1 At the prompt type enable and press . 2 When a password prompt displays, enter the password and press . The Privileged EXEC mode prompt displays as the device host name followed by #. For example: console# To list the Privileged EXEC commands, type a question mark at the command prompt. To return from Privileged EXEC mode to User EXEC mode, type disable and press . The following example illustrates accessing privileged EXEC mode and then returning to the User EXEC mode: Use the exit command to return to a previous mode. To configure the device, enter the next level, Global Configuration mode. Global Configuration Mode The Global Configuration mode manages device configuration on a global level.

The Global Configuration mode displays as the device host name followed by (config) and the pound sign #. To list the Global Configuration commands, enter a question mark at the command prompt. The following example illustrates how to access Global Configuration mode and return back to the Privileged EXEC mode: Interface Configuration Mode The Interface Configuration mode configures the device at the physical interface level (port, VLAN, or LAG). Interface commands that require subcommands have another level, called the Subinterface Configuration mode. A password is not required to access this level. The following example, places the CLI in Interface Configuration mode on port 1/0/1. The sntp command is then applied to that port. To run a command in a mode, which does not contain it, use do before the command, as in the following example: console# configure console(configure)# console# console# configure console(config)# exit console# console# configure console(config)# interface gi1/0/1 console(config-if)# sntp client enable console# configure console(config)# interface gi1/0/1 console(config-if)# sntp client enable console(config-if)# do show sntp configurationDell PowerConnect 55xx Systems User Guide 71 FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxUGAdvanced Configuration.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY Accessing the Device Through the CLI You can manage the device using CLI commands, over a direct connection to the terminal console, or via a Telnet connection. Direct Connection Connect the device to the console and enter the CLI commands upon receiving a prompt. Telnet Connection Telnet is a terminal emulation TCP/IP protocol. RS-232 terminals can be virtually connected to the local device through a TCP/IP protocol network. Telnet is an alternative to a local login terminal, where a remote login is required. The device supports up to four simultaneous Telnet sessions. All CLI commands can be used over a Telnet session. If access is via a Telnet connection, ensure that the device has an IP address and that software has been downloaded to the device. To start a Telnet session: 1 Select Start > Run. The Run window opens. 2 Type cmd. The cmd window opens. 3 In the cmd window, type Telnet . The Telnet session begins.72 Dell PowerConnect 55xx Systems User Guide FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxUGAdvanced Configuration.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY Retrieving an IP Address Receiving an IP Address from a DHCP Server When using the DHCP protocol to retrieve an IP address, the device acts as a DHCP client. When the device is reset, the DHCP command is saved in the configuration file, but the IP address is not. To retrieve an IP address from a DHCP server, perform the following steps: 1 Select and connect any port to a DHCP server or to a subnet that has a DHCP server on it. 2 Type the following commands to use the selected port for receiving the IP address. a Assigning dynamic IP Addresses on a port: b Assigning a dynamic IP Addresses on a VLAN: The interface receives the IP address automatically. console# configure console(config)# interface gi1/0/1 console(config-if)# ip address dhcp console# configure console(config)# interface vlan 1 console(config-if)# ip address dhcpDell PowerConnect 55xx Systems User Guide 73 FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxUGAdvanced Configuration.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY 3 To verify the IP address, type show ip interface at the system prompt, as shown in the following example. When configuring/receiving IP addresses through DHCP and BOOTP (an older version of DHCP), the configuration received from these servers includes the IP address and may include the subnet mask and default gateway. NOTE: It is not necessary to delete the device configuration to retrieve an IP address from the DHCP server. NOTE: When copying configuration files, avoid using a configuration file that contains an instruction to enable DHCP on an interface that connects to the same DHCP server, or to one with an identical configuration. In this instance, the device retrieves the new configuration file and boots from it. The device then enables DHCP, as instructed in the new configuration file, and the DHCP instructs it to reload the same file. NOTE: If you configure a DHCP IP address, this address is dynamically retrieved, and the ip address dhcp command is saved in the configuration file. In the event of master failure, the backup will again attempt to retrieve a DHCP address. This could result in one of the following: • The same IP address may be assigned. • A different IP address may be assigned, which could result in loss of connectivity to the management station. • The DHCP server may be down, which would result in IP address retrieval failure, and possible loss of connectivity to the management station. Receiving an IP Address From a BOOTP Server The standard BOOTP protocol is supported and enables the device to automatically download its IP host configuration from any standard BOOTP server in the network. In this case, the device acts as a BOOTP client. console# show ip interface IP Address I/F Type Directed Precedence Status Broadcast ----------------- --------- -------- -------- -------- ----- 0.0.0.0/32 gi2/0/1 DHCP disable No Valid 10.5.234.232/24 vlan 1 Static disable No Valid74 Dell PowerConnect 55xx Systems User Guide FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxUGAdvanced Configuration.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY To retrieve an IP address from a BOOTP server: 1 Select and connect any port to a BOOTP server or subnet containing such a server. 2 At the system prompt, enter the delete startup configuration command to delete the Startup Configuration from flash. The device reboots with no configuration and in 60 seconds starts sending BOOTP requests. The device receives the IP address automatically. NOTE: When the device reboot begins, any input at the ASCII terminal or keyboard automatically cancels the BOOTP process before completion and the device does not receive an IP address from the BOOTP server. The following example illustrates the process: To display the IP address, enter the show ip interface command.

AAA uses both local and remote user databases. Data encryption is handled through the SSH mechanism. Passwords can be configured for the following services: • Terminal • Telnet • SSH • HTTP • HTTPS NOTE: When creating a user name, the default priority is 1, which provides access but not configuration rights. A priority of 15 must be set to enable access and configuration rights to the device. Although user names can be assigned privilege level 15 without a password, it is recommended to always assign a password. If there is no specified password, privileged users can access the Web interface with any password. NOTE: Passwords can be secured by using password management commands to force aging out of passwords, or expiration of passwords. For more information, see "Management Security" on page 261. Initial Configuration and Password Recovery The system is delivered without a default password, and all passwords must be defined by the user. If a user-defined password is lost, a password recovery procedure can be invoked from the Startup menu. This procedure is applicable for the local terminal only and enables a single access to the device from the local terminal with no password entered. The full mode of password recovery mechanism can be enabled/disabled through the CLI (service password-recovery command). This affects password recovery in the following way: • Enabled: When the password-recovery mechanism is invoked, one-time access to the device without a password is enabled and all configuration and user files are retained.76 Dell PowerConnect 55xx Systems User Guide FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxUGAdvanced Configuration.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY • Disabled: When the password-recovery mechanism is invoked, one-time access to the device without a password is stilled enabled, however all configuration files (startup and backups) are removed and the following log message is generated to the terminal after boot process completed: “All configuration and user files were removed” Configuring an Initial Terminal Password To configure an initial terminal password, enter the following commands: Configuring an Initial Telnet Password To configure an initial Telnet password, enter the following commands: console(config)# aaa authentication login default line console(config)# aaa authentication enable default line console(config)# line console console(config-line)# login authentication default console(config-line)# enable authentication default console(config-line)# password george console(config)# aaa authentication login default line console(config)# aaa authentication enable default line console(config)# line telnet console(config-line)# login authentication default console(config-line)# enable authentication default console(config-line)# password bobDell PowerConnect 55xx Systems User Guide 77 FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxUGAdvanced Configuration.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY Configuring an Initial SSH Password To configure an initial SSH password, enter the following commands: Configuring an Initial HTTP Password To configure an initial HTTP password, enter the following commands: Configuring an Initial HTTPS Password To configure an initial HTTPS password, enter the following commands: Enter the following commands once when configuring use of a terminal, a Telnet, or an SSH session, for an HTTPS session.

The TFTP server must be configured before downloading the software. Software Auto Synch in Stack When several units are stacked, they must all run the same software version. When a new slave device is inserted into the stack, it is first checked for compatibility (meaning that the master can run firmware upgrade/downgrade to the slave unit), and if found compatible, its boot and image software versions are automatically updated with the Master’s. If the slave is found not compatible, it is shutdown. A SYSLOG message is sent when a master synchronizes a slave's software. System Image Download When the device boots, it decompresses the system image from the flash memory area and runs it. When a new image is downloaded, it is saved in the other area allocated for the other system image copy. On the next boot, the device decompresses and runs the image from the currently active system image. A system image can be downloaded through a USB port or a TFTP server.

The MAC addresses can be dynamically learned, or they can be statically configured. Port security has the following modes: • Classic Lock — Locked port security monitors both received and learned packets that are received on specific ports. Access to the locked port is limited to users with specific MAC addresses. These addresses are either manually defined on the port, or learned on that port before it was locked. • Limited Dynamic Lock — When a packet is received on a locked port, and the packet’s source MAC address is not tied to that port (either it was learned on a different port, or it is unknown to the system), a protection mechanism, which provides various options is invoked. Unauthorized packets arriving to a locked port are either: – Forwarded – Discarded with no trap – Discarded with a trap – The port is shutdown Locked port security enables storing a list of MAC addresses in the configuration file. The MAC addresses are restored when the device is reset. Disabled ports can be activated from the Port Configuration page.

It contains the following topics: • ACL Overview • MAC-Based ACLs • MAC-Based ACEs • IPv4-Based ACLs • IPv4-Based ACEs • IPv6-Based ACLs • IPv6-Based ACEs ACL Overview Access Control Lists (ACLs) enable network managers to define classification actions and rules for specific ingress or egress ports. Packets entering an ingress or egress port, with an active ACL, are either admitted or denied entry. If entry is denied, the ingress or egress port may be disabled, for example, a network administrator defines an ACL rule that states that port number 20 can receive TCP packets, however, if a UDP packet is received, the packet is dropped. ACLs are composed of Access Control Entries (ACEs) that are rules that determine traffic classifications. Each ACE is a single rule, and up to 256 rules may be defined on each ACL, and up to 3000 rules globally. Rules are not only used for user configuration purposes, they are also used for features like DHCP Snooping, Protocol Group VLAN and iSCSI, so that not all 3000 rules are available for ACEs. It is expected that there will be at least 2000 rules available. If there are fewer rules available, this may be due to DHCP Snooping or iSCSI optimization. Reduce the number of entries in DHCP Snooping or reduce the max number of TCP connections in the iSCSI configuration in order to free rules for ACEs.

It contains the following topics: • Port-Based Authentication Overview • Dot1x Overview • Port-Based Authentication Global • Port-Based Authentication Interface Settings • Monitoring Users • Host Authentication • Port Authentication Users Port-Based Authentication Overview Port-based authentication enables authenticating system users on a per-port basis via an external server. Only authenticated and approved system users can transmit and receive data. Ports are authenticated via the RADIUS server using the Extensible Authentication Protocol (EAP). Port Authentication includes: • Authenticators — Specifies the device port that is authenticated before permitting system access. • Supplicants — Specifies the host connected to the authenticated port hat is requesting to access the system services. • Authentication Server — Specifies the external server, for example, a RADIUS server, which performs authentication on behalf of the authenticator, and indicates whether the supplicant is authorized to access system services. Port-based authentication creates two access states: • Controlled Access — Permits communication between the supplicant and the system, if the supplicant is authorized. • Uncontrolled Access — Permits uncontrolled communication, regardless of the port authorization state.Dell PowerConnect 55xx Systems User Guide 133 FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxU_Switching_NetworkSecurity.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY The device supports Port Based Authentication via RADIUS servers. Dot1x Overview Dot1x is an IEEE standard for port-based network access control. The Dot1x framework enables a device (the supplicant) to request port access from a remote device (authenticator) to which it is connected. The supplicant is permitted to send data to the port only after it is authenticated and authorized. If it is not authenticated and authorized, the authenticator discards the supplicant data, unless the data is sent to a Guest VLAN and/or non-authenticated VLANs. Authentication of the supplicant is performed by an external RADIUS server through the authenticator. The authenticator monitors the results of the authentication. In the Dot1x standard, a device can be a supplicant and an authenticator at a port, simultaneously requesting and granting port access. However, this device can only act as an authenticator, and does not take on the role of a supplicant. The following varieties of Dot1x exist: • Single session Dot1x: – A1—Single-session/Single Host — In this mode, the switch, as an authenticator, supports a single Dot1x session, and grants permission to use the port to an authorized supplicant. All other access requests, made by other devices received from the same port, are denied until the authorized supplicant is no longer using the port, or the access request is to an unauthenticated or guest VLAN. – Single-session/Multiple Hosts—This follows the Dot1x standard. In this mode, the switch, as an authenticator, enables any device to use a port, as long as it has been granted permission as a supplicant at the port. • Multi-Session Dot1x—Every device (supplicant) connecting to a port must be authenticated and authorized by the switch (authenticator), separately in a different Dot1x session. This is the only mode that supports Dynamic VLAN Assignment (DVA).134 Dell PowerConnect 55xx Systems User Guide FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxU_Switching_NetworkSecurity.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY Dynamic VLAN Assignment (DVA) Dynamic VLAN Assignment (DVA) is also referred to as RADIUS VLAN Assignment in this guide. When a port is in Multiple Session mode and is DVA-enabled, the switch automatically adds the port as an untagged member of the VLAN that is assigned by the RADIUS server during the authentication process. The switch classifies untagged packets to the assigned VLAN if the packets originated from the devices or ports that are authenticated and authorized. For a device to be authenticated and authorized at a DVA-enabled port: • The RADIUS server must authenticate the device and dynamically assign a VLAN to the device. • The assigned VLAN must not be the default VLAN and must have been created on the switch. • The switch must not be configured to use both a DVA and a MAC-based VLAN group. • A RADIUS server must support DVA with RADIUS attributes tunnel-type (64) = VLAN (13), tunnel-media-type (65) = 802 (6), and tunnel-privategroup-id = a VLAN ID. Dynamic Policy/ACL Assignment The Dynamic Policy/ACL Assignment feature enables specifying a userdefined ACL or policy in the RADIUS server. After a successful authentication, the user is assigned that ACL. Authentication Methods The possible authentication methods are: • Dot1x — The switch supports this authentication mechanism, as described in the standard, to authenticate and authorize Dot1x supplicants. • MAC-based — The switch can be configured to use this method to authenticate and authorize devices that do not support Dot1x. The switch emulates the supplicant role on behalf of the non-Dot1x-capable devices, and uses the MAC address of the devices as the username and password, when communicating with the RADIUS servers. MAC addresses for Dell PowerConnect 55xx Systems User Guide 135 FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxU_Switching_NetworkSecurity.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY username and password must be entered in lower case and with no delimiting characters (for example: aaccbb55ccff). To use MAC-based authentication at a port: – A Guest VLAN must be defined. – The port must be Guest-VLAN-enabled. – The packets from the first supplicant, at the port before it is authorized, must be untagged. You can configure a port to use Dot1x only, MAC-based only, or Dot1x and MAC-based authentication. If a port is configured to use both Dot1x and MAC-based authentication, a Dot1x supplicant has precedence over a non-Dot1x device. The Dot1x supplicant preempts an authorized, but non-Dot1x device, at a port that is configured with a single session. Unauthenticated VLAN and Guest VLANs Unauthenticated VLANs and Guest VLANs provide access to services that do not require the subscribing devices or ports to be Dot1x or MAC-Based authenticated and authorized. An unauthenticated VLAN is a VLAN that allows access by authorized and unauthorized devices or ports. You can configure one or more VLAN to be unauthenticated in the VLAN Membership pages in "VLANs" on page 466. An unauthenticated VLAN has the following characteristics: • It must be a static VLAN, and cannot be the Guest VLAN or the default VLAN. • The VLAN’s member ports must be manually configured as tagged members. • The member ports must be trunk and/or general ports. An access port cannot be member of an unauthenticated VLAN. The Guest VLAN, if configured, is a static VLAN with the following characteristics. • It must be manually defined from an existing, static VLAN. • It is automatically available only to unauthorized devices, or to ports of devices that are connected and Guest VLAN enabled. 136 Dell PowerConnect 55xx Systems User Guide FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxU_Switching_NetworkSecurity.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY • If a port is Guest-VLAN-enabled, the switch automatically adds the port as an untagged member of the Guest VLAN when the port is not authorized, and removes the port from the Guest VLAN when the first supplicant of the port is authorized. • The Guest VLAN cannot be used as both the Voice VLAN and an unauthenticated VLAN. The switch also uses the Guest VLAN for authentication at ports configured with Multiple Session mode and MAC-based authentication. Therefore, you must configure a Guest VLAN before you can use the MAC-based authentication mode. For authentication to function, it must be activated both globally, in the PortBased Authentication Global page and individually on each port, in the PortBased Authentication Interface Settings pages. Monitoring Mode Monitoring mode enables providing users who fail authentication with limited network access. This enables these users to correct the reason that the authentication failed. The following are the main aspects of this feature: • Enables successful authentications using the returned RADIUS information • Provides a mechanism to report unsuccessful authentications without negative repercussions to the user due to administrator errors • Accurately reports the data received from the successful and nonsuccessful operations so that appropriate changes to problem areas may be made. The Dot1x monitoring activation command includes a special VLAN that is used when there is no access interface configuration present and the client(s) unsuccessfully authenticates. These clients are placed in the special VLAN. For users that unsuccessfully authenticate during re-authentication process, but already have existing VLANs configured, the failure to authenticate does not put them in a disabled state but places them back to the existing configuration.Dell PowerConnect 55xx Systems User Guide 137 FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxU_Switching_NetworkSecurity.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY Port-Based Authentication Global To globally configure authentication: 1 Click Switching > Network Security > Dot1 Authentication > Port Based Authentication Global to display the Port Based Authentication Global page.

The implementation of SNTP is based on SNTPv4 (RFC 2030). SNTP is a simple and lighter version of NTP, and can be used when the ultimate performance of the full NTP implementation, described in RFC-1305, is not required. SNTP operates with NTP, thus an SNTP client can work with both SNTP and NTP servers. The switch operates only as a client, and cannot provide time services to other systems. SNTP Server Types The switch can accept time information from the following server types: • Unicast Polling for Unicast information is used for polling a server whose IP address is known. This is the preferred method for synchronizing device time, as it is most secure. Up to eight SNTP servers can be defined. If this method is selected, SNTP information is accepted only from SNTP servers defined in the SNTP Servers page. Time levels T1 - T4 (see the "Algorithm for Selecting Designated SNTP Server" on page 180 section) are used to determine from which server time information is accepted. If Unicast polling is not enabled or if no servers are defined on the device, the device accepts time information from any SNTP server of the type that is enabled, which responds. • Anycast Polling for Anycast information is used when the SNTP server’s IP address is not defined or it cannot be reached. If this method is enabled, time information can be received from any SNTP server on the network. The Dell PowerConnect 55xx Systems User Guide 179 FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxUGSystemConfig.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY device time and date are synchronized when it proactively requests synchronization information. Anycast polling to get time information is preferable to Broadcast polling, because it is more secure. Time levels T3 and T4 are used to determine from which server time information is accepted. • Broadcast Broadcast information is used if receiving Broadcast packets has been enabled, and one of the following situations occurs: – The SNTP server IP address has not been defined. – Several time-information packets are received and the Broadcast time is best according to the algorithm defined in "Algorithm for Selecting Designated SNTP Server" on page 180. Broadcast is the least secure method of receiving time, because it is both unsecured and the time information was not specifically requested by the device. Anycast is also unsecured, but time-information packets are only accepted if they were requested. Stratums Each SNTP server is characterized by stratums, which define the accuracy of its clock. The stratum is the distance, in terms of NTP hops, from the most authoritative time server. The lower the stratum (where zero is the lowest), the more accurate the clock. The switch accepts time from stratum 1 and above. The following provides examples of clocks from various stratums: • Stratum 0 — A real time clock is used as the time source, for example, a GPS system. • Stratum 1 — A server that is directly linked to a Stratum 0 time source is used. • Stratum 2 — The time source is distanced from the Stratum 1 server over a network path, for example, a Stratum 2 server receives the time over a network link, via NTP, from a Stratum 1 server.180 Dell PowerConnect 55xx Systems User Guide FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxUGSystemConfig.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY Algorithm for Selecting Designated SNTP Server Messages received from SNTP servers are logged, until there are three responding servers, or the timer expires. In any event, when the third message is received, the timer expires. A server is selected to be the “designated server” according to the following criteria: • The stratum (the distance in terms of NTP hops from the best authoritative time servers) is considered, and the server with the best (lowest) stratum is selected. • If there is a tie in stratums, packets from servers defined on the device are preferred to Anycast packets, which in turn are preferred to Broadcast packets. • If multiple servers pass the above criteria, then the server that sent the first (earliest) time packet is chosen. If a better server is discovered later, it is selected to be the “designated server” at that time. Polling You can configure the system to acquire time information in the following ways: • Enable polling — Time information is requested every polling interval. • Do not enable polling — Time information is received when the system is brought up and every time that a topological change is made to the Running Configuration file, for example when an SNTP Unicast server is added. This is configured by the user in the SNTP Global Settings page. On power up, when the switch sends a request and there is no reply, it issues another request (three retries at most) after 20 seconds of waiting. If no SNTP server is found, the process is invoked every “poll interval” (set in the SNTP Global Settings page), and a management trap is triggered. Authentication You can require that SNTP servers be authenticated, although this is not mandatory (see the SNTP Authentication pages).

MD5 is an algorithm that produces a 128-bit hash value. MD5 is a variation of MD4, and increases MD4 security. MD5 both verifies the integrity of the communication and authenticates the origin of the communication.

Each log is a set of entries that record system events. It contains the following topics: • System Log Overview • Global Parameters • RAM Log • Log File (in Flash) • Login History • Remote Log Server System Log Overview System logs record events and report errors or informational messages. Some aspects of system logging can be configured, as described below. When you configure system logging, the configuration applies to all units in the stack. Some events are automatically logged, such as hardware problems. You may enable/disable logging the following types of events: • Authentication Events in the Global Parameters page • Copy File Events in the Global Parameters page • Management Access Events in the Global Parameters page • Login History in the Login History page Event messages have a unique format, as per the System Logs (SYSLOG) protocol recommended message format for all error reporting, for example, SYSLOG and local device reporting messages are assigned a severity code, and include a message mnemonic that identifies the source application generating the message. Messages may be filtered, based on their urgency or relevancy. Events may be logged to the following destinations: • Console • Logging buffer (RAM)— Messages are stored in a cyclical file buffer. When the maximum number of messages is reached, messages are written starting at the beginning of the buffer (overwriting the old messages). 196 Dell PowerConnect 55xx Systems User Guide FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxUGSystemConfig.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY Logs stored on the Logging buffer are deleted when the device is reset. • Logging file (flash) — Messages are stored in flash memory. When the buffer is full, messages are written starting at the beginning of the memory block (overwriting the old messages). • SYSLOG Server — Messages are sent to a remote server. This is useful for central and remote management and to provide more space for storage of messages. Up-to eight SYSLOG servers can be defined in the Remote Log Server Settings pages. You can select where to send logging messages according to their severity. Each of the severity level can be directed to the console, RAM log, flash log file or SYSLOG server or to any combination of these destinations. Global Parameters Use the Global Parameters page to enable/disable logging for the following logging severity levels. – Emergency — If the device is down or not functioning properly, an emergency log message is saved to the specified logging location. – Alert — An alert log is saved if there is a serious device malfunction, for example, all device features are down. – Critical — A critical log is saved if a critical device malfunction occurs, for example, two device ports are not functioning, while the rest of the device ports remain functional. – Error — A device error has occurred, for example, a single port is offline. – Warning — The lowest level of a device warning. The device is functioning, but an operational problem has occurred. – Notice — Provides device information to which you might have to respond. – Informational — Provides device information to which you do not have to respond. – Debug — Provides debugging messages.

This enables device operation in a pure-IPv6 network, as well as in a combined IPv4/IPv6 network. Difference Between IPv4 and IPv6 Addressing The primary difference between IPv4 to IPv6 is the length of network addresses. IPv6 addresses are 128 bits, whereas IPv4 addresses are 32 bits. Thus, IPv6 addresses enable the use of many more unique addresses. The 128-bit IPv6 address format is divided into eight groups of four hexadecimal digits. Abbreviation of this format by replacing a group of zeros with double colons (::) is acceptable. IPv6 address representation can be further simplified by suppressing the leading zeros.210 Dell PowerConnect 55xx Systems User Guide FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxUGSystemConfig.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY All IPv6 address formats are acceptable, yet for display purposes, the system displays the most abbreviated form, which replaces groups of zeros with double colons and removes the leading zeros. IPv6 Prefixes While Unicast IPv6 addresses written with their prefix lengths are permitted, in practice their prefix lengths are always 64 bits, and therefore are not required to be expressed. Any prefix that is less than 64 bits is a route or address range that summarizes a portion of the IPv6 address space. For every assignment of an IP address to an interface, the system runs the Duplicate Address Detection (DAD) algorithm to ensure uniqueness. An intermediary transition mechanism is required for IPv6-only nodes to communicate with IPv6 nodes over an IPv4 infrastructure. The tunneling mechanism implemented is the Intra-Site Automatic Tunnel Addressing Protocol (ISATAP). This protocol treats the IPv4 network as a virtual IPv6 local-link, with each IPv4 address mapped to a Link Local IPv6 address. IPv4 Interface Parameters You can assign IP addresses to the interface in the following ways: • Manual Assignment — Described below • DHCP Server Assignment — Described in "DHCP IPv4 Interface" on page 214 Multiple IP addresses can be configured in the IPv4 Interface Parameters pages. These IP addresses can be assigned to a port, LAG, or VLAN interface. When an IP address is assigned, it is checked for uniqueness in the following way: • A gratuitous ARP request is sent three times every three seconds. • If after (3+1)*3 = 12 seconds the switch has not received the ARP response, the IP address is considered to be unique. • During the procedure the switch has to reply to gratuitous ARP and probe ARP requests with the validated IP address.Dell PowerConnect 55xx Systems User Guide 211 FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxUGSystemConfig.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY The IP address is assigned even if the above validation procedure concludes that the IP address in question is not unique, but a SYSLOG message is generated.

It then sends Address Resolution Protocol (ARP) packets to confirm the uniqueness of the IP address. If the ARP response shows that the IP address is in use, the switch sends a DHCPDECLINE message to the DHCP server, and sends another DHCPDISCOVER packet that restarts the process. IP address collisions occur when the same IP address is used in the same IP subnet by more than one device. Address collisions require administrative actions on the DHCP server and/or the devices that collide. Up to 32 interfaces (ports, LAGs, and/or VLAN) on the switch can be configured with a static or dynamic IP address. The IP subnets to which these IP addresses belong are known as directly connected/attached IP subnets. The IP address assignment rules for the switch are as follows: • If the IP address on the switch is changed, the switch issues gratuitous ARP packets to the corresponding VLAN, to check IP address collisions. • When a client must renew its lease, prior to its expiration date, a DHCPREQUEST message is sent. • A specific interface can have either a static IP address or a dynamic IP address, but not both.Dell PowerConnect 55xx Systems User Guide 215 FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxUGSystemConfig.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY To define the switch as a DHCP client: 1 Click System > IP Addressing > DHCP IPv4 Interface in the tree view to display the DHCP IPv4 Interface: Summary page.

The Intra-Site Automatic Tunnel Addressing Protocol (ISATAP) is an IPv6 transition mechanism that is used to transmit IPv6 packets between dual-stack nodes (nodes that can accept both IPv4 and IPv6 addresses) on top of an IPv4 network. When enabling ISATAP on a tunnel interface, an explicit IPv4 address is configured as the tunnel source, or an automatic mode exists, where the lowest IPv4 address is assigned to an IP interface. This source IPv4 address is used for setting the tunnel interface identifier according to ISATAP addressing conventions. When a tunnel interface is enabled for ISATAP, the tunnel source must be set for the interface in order for the interface to become active. An ISATAP address is represented using the [64-bit prefix]:0:5EFE:w.x.y.z, where 5EFE is the ISATAP identifier and w.x.y.z is a public or private IPv4 address.

User authentication can occur: • Locally • Via an external server, such as a TACACS+ or a RADIUS server User authentication occurs in the order that the methods are selected, for example, if both the Local and RADIUS options are selected, the user is authenticated first locally. If the local user database is empty, the user is authenticated via the RADIUS server. If an error occurs during the authentication, the next selected method is used. If an authentication method fails, or the user has an insufficient privilege level, the user is denied access to the switch. The switch then stops, does not continue, and does not attempt to use the next authentication method. If a privilege level is redefined, the user must also be re-defined. User authentication can also be set to None, in which case no authentication is performed. The process of configuring authentication for management access methods is divided into the following stages: • Create an authentication profile, as described below • Assign an authentication profile to a management method, as described in "Select Authentication" on page 272270 Dell PowerConnect 55xx Systems User Guide FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxUGSystemConfig.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY To create an authentication profile: 1 Click System > Management Security > Authentication Profiles in the tree view to display the Authentication Profiles: Summary page.

The DHCP server can allocate IP addresses in the following modes: • Static Allocation — The hardware address of a host is manually mapped to an IP address. • Permanent Allocation — An IP address sent to the client through a standard request-reply mechanism, is owned by that client permanently (unless changes in the network environment/connections take place, for any reason). • Dynamic Allocation — A client obtains a leased IP address for a specified period of time. The IP address is revoked at the end of this period, and the client must request another IP address. 298 Dell PowerConnect 55xx Systems User Guide FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxUGSystemConfig.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY DHCP Server Properties If the device is configured to act as a DHCP server, pinging capability can be enabled.

It contains the following topics: • SNMP Overview • SNMP Global Settings • SNMP Views • SNMP Access Control (Groups) • SNMP User Security Model (Users) • SNMP Communities • SNMP Notification Filters • SNMP Notification Recipients SNMP Overview The switch supports the SNMPv1, SNMPv2 and SNMPv3. SNMP v1 and v2 The SNMP agent maintains a list of variables that are used to manage the switch. These variables are stored in the Management Information Base (MIB) from which they may be presented. The SNMP agent defines the MIB specification format, as well as the format used to access the information over the network. Access rights to the SNMP agents are controlled by access strings. SNMPv1 and v2 are enabled by default. SNMP v3 In addition to the features provided by SNMPv1 and SNMPv2, SNMPv3 applies access control and a new trap mechanism to SNMPv1 and SNMPv2 PDUs. In addition, a User Security Model (USM) can be defined, which includes: • Authentication — Provides data integrity and data origin authentication. Dell PowerConnect 55xx Systems User Guide 315 FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxUGSystemConfig.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY • Privacy — Protects against disclosure of message content. Cipher BlockChaining (CBC) is used for encryption. Either authentication alone can be enabled on an SNMP message, or both authentication and privacy can be enabled on an SNMP message. However privacy cannot be enabled without authentication. • Timeliness — Protects against message delay or message redundancy. The SNMP agent compares incoming message to the message time information. • Key Management — Defines key generation, updates, and use. The switch supports SNMP notification filters, based on Object IDs (OIDs), which are used by the system to manage switch features. Authentication or Privacy Keys are modified in the User Security Model (USM). SNMPv3 can only be enabled if the Local Engine ID is enabled. SNMP Access Rights Access rights in SNMP are managed in the following ways: • SNMPv1 and SNMPv2 — Communities The community name is a password sent by the SNMP management station to the device for authentication purposes. A community string is transmitted along with the SNMPv1,v2 frames, but neither the frames nor the community string are encrypted. Since SNMPv1 and SNMPv2 are not encrypted, they are not secure. Communities can be associated with views or groups, and they are defined in the Community pages. • SNMPv3 — Users and Groups SNMP v3 works with users instead of communities. The users belong to groups that have access rights assigned to them. Users are defined in the User Security Model pages SNMPv3 provides two security mechanisms: – Authentication — The switch checks that the SNMP user is an authorized system administrator. This is done for each and every frame. 316 Dell PowerConnect 55xx Systems User Guide FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxUGSystemConfig.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY – Privacy — SNMP frames can carry encrypted data. These mechanisms can be combined to provide three levels of security: – No security – Authentication – Authentication and Privacy. Note that for both authentication and privacy to be enabled, two groups with the same name, one with authentication and one with privacy, must be created. A group is a label for a combination of attributes that determines whether members have read, write, and/or notify privileges. Users can be associated with a group. A group is operational only when it is associated with an SNMP user. Model OIDs The following are the switch model Object IDs (OIDs): SNMP Global Settings The Engine ID is used by SNMPv3 entities to uniquely identify themselves. An SNMP agent is considered an authoritative SNMP engine. This means that the agent responds to incoming messages (Get, GetNext, GetBulk, Set), and sends Trap messages to a manager. The agent's local information is encapsulated in fields in the message. Each SNMP agent maintains local information that is used in SNMPv3 message exchanges (not relevant for SNMPv1 or SNMPv2). The default SNMP Engine ID is comprised of the enterprise number and the default MAC address. The SNMP engine ID must be unique for the administrative domain, so that no two devices in a network have the same engine ID. Model Name Object ID PC5524 10895.3030 PC5524P 10895.3032 PC5548 10895.3031 PC5548P 10895.3033Dell PowerConnect 55xx Systems User Guide 317 FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxUGSystemConfig.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY The local information is stored in four read-only MIB variables: snmpEngineId, snmpEngineBoots, snmpEngineTime, and snmpEngineMaxMessageSize.

The field value is a hexadecimal string. Each byte in hexadecimal character strings is two hexadecimal digits. Each byte can be separated by a period or a colon. The Engine ID must be defined before SNMPv3 is enabled. For stacked devices, verify that the Engine ID is unique for the administrative domain. This prevents two devices in a network from having the same Engine ID. 318 Dell PowerConnect 55xx Systems User Guide FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxUGSystemConfig.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY – Use Default — Check to use the device-generated Engine ID.

It contains the following topics: • File Management Overview • Auto-Update/Configuration Feature • File Download • File Upload • Active Images • Copy Files • File System File Management Overview This section describes the system files found in the system and how they can be updated (downloaded) and backed up (uploaded). System Files The following system files are maintained on the system: • Startup Configuration File — Files with extension .text. These files contain the commands required to configure the device at startup or after reboot. The Startup Configuration file is created from the Running Configuration file, or can be created from another file. • Running Configuration File — Files with extension .text. These files contain all Startup Configuration file commands, as well as all commands entered during the current session. After the device is powered down or rebooted, all commands stored in the Running Configuration file are lost. During the startup process, all commands in the Startup Configuration file are copied to the Running Configuration file, and applied to the device. During the session, new configuration commands are added to the Running Configuration file. To update the Startup Configuration file with these configuration commands, the Running Configuration file must first be copied to the Startup Configuration file before powering down the 338 Dell PowerConnect 55xx Systems User Guide FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxUGSystemConfig.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY device. This can be done manually in the Copy Files page or see "AutoUpdate/Configuration Feature" on page 338 for more information about how to perform this automatically. • Image Files—Files with extension .ros. System file images are saved in two flash files called Image 1 and Image 2. The active image contains the active copy, while the other image contains a backup copy. The device boots and runs from the active image. If the active image is corrupted, the system automatically boots from the non-active image. This is a safety feature for faults occurring during the software upgrade process. Downloading/Uploading System Files System files can be manually loaded from (downloaded) or copied to (uploaded) a TFTP server or a USB drive. This can be done in one of the following ways: • Manually—System files can be downloaded using the File Download page and uploaded using the File Upload page. • Automatically (Auto Update/Configuration)—System files can be downloaded automatically, as follows: – Auto-Configuration—If the Auto-Configure feature is enabled (in the Auto Update of Configuration/Image File page), the Startup Configuration file (in various conditions described below) might be automatically updated after reboot. – Auto-Update—If the Firmware Auto-Update feature is enabled in the Auto Update of Configuration/Image File page, the image file is might be automatically updated (in various conditions described below). Auto-Update/Configuration Feature The Auto-Update/Configuration feature enables initial configuration of the device and upgrading of the firmware through an automatic process, which enables the administrator to ensure that the configuration/firmware of all the devices in the network is up-to-date. Dell PowerConnect 55xx Systems User Guide 339 FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxUGSystemConfig.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY The required configuration files/images are stored on a USB key or TFTP server, and these are downloaded to all the devices in the network when the device boots up instead of booting from a local startup configuration file. Auto-Update/Configuration also enables quick installation of new devices on the network, since an out-of-box device can be configured to retrieve its configuration file from the network/USB, allowing instant access to it from the administrator's management station and up-to-date configuration on the device. NOTE: If Auto-Update is performed through the USB port, in addition to upgrading the Startup Configuration and image file, a new IP address can also be assigned to the device. See "Setup Files" on page 339 below. Setup Files In addition to placing configuration and image files on the USB key, the USB key might also contain a setup file, which is a file with a .setup extension. Setup File Contents A setup file contains one or more lines. Each line contains some or all of the following fields: • MAC Address—This indicates to which device the line applies. In this way, a single setup file can be used for multiple devices. • New IP Address—The new IP address to be assigned to the device. • New IP Address Mask—The IP address mask to be applied to the new IP address assigned to the device. • Configuration File Name—Name of the configuration file to be used as the Startup Configuration. • Image File Name—Name of the image file to be loaded on device. • Flag—Indicates the status of the line. The following values can be used in this field: – In-Use—This line has already been applied. It is no longer a candidate for future use. – Invalid—The line is invalid, do not use. – Blank—There is no value for the flag field.

Automatic DHCP IP Interface Assignment The user can manually define a DHCP interface in the DHCP IPv4 page. If the user does not do this, the switch automatically creates a DHCP interface on the VLAN with the lowest VLAN ID that does not have an IP address defined on it after boot if both of the following conditions are fulfilled: • There is no DHCP IP interface. • There is a VLAN without an IP address. Preparations for Using Auto Update/Configuration from a USB Drive Before Auto-Update/Configuration from a USB drive can be performed, the following steps must be performed: 1. Enable Auto-Update/Configuration in the Auto Update of Configuration/Image File page. 2. (Optional) Create a line in the setup file for this device containing the required options and load it on the USB key. 3. Load configuration/image files on the USB key as required. 4. Insert the USB key in the USB drive and reboot the device. Performing Auto-Update from a USB Drive When Auto-Update is initiated from a USB drive, the following steps are performed: 1. Locate the correct setup file—The USB drive is searched for a setup file. One of the following can occur: – Setup file is not found—The root folder of the USB is searched for an image files (with .ros extension). • The image file with the most recent version is loaded into the image file if the versions are different.344 Dell PowerConnect 55xx Systems User Guide FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxUGSystemConfig.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY • If a new image file was loaded, the device is rebooted. • The USB drive is searched for a configuration file (.text extension). If there is more than one configuration file, the file named powerconnect.text is loaded (if it is not found the process is stopped). – One or more setup files are found—If a single setup file is found, it is used; if several files are found, the file powerconnect.setup is used. If no setup file with this name is found, the process is stopped. 2. Find the line in the setup file relevant to the device—When the correct setup file is found, it is searched for a line relevant to the device, as follows: – The setup file is searched for a line with format A or B in which there is a match to the device's MAC address. If such line is found, and its format is valid (the field is empty), the line is applied. – If no line for the specific device was found, the setup file is searched for valid lines with formats C or D. The first line found is applied. 3. Apply the correct line—When the correct line in the setup file is found, it is applied, as follows: – If the line contains an IP address and IP mask, the IP address is configured on the default VLAN. – If the line contains an image file and its version differs from the current image file version, the USB image file is loaded and the switch is rebooted. – If a new image file was loaded, it is loaded onto all units in the stack. – If the line contains a configuration file, the configuration file is appended to running configuration file. 4. Mark the flag in the applied line—When the line is applied (successfully or not), its flag is set, as follows: – If the line contains an IP address and IP mask (format C or D), the IP address is configured on the default VLAN and the line is marked as "in-use". This ensures that the line is not used for another device. – If the line was not applied successfully, for one of the following reasons, the line is marked as "invalid" and a SYSLOG message is sent.Dell PowerConnect 55xx Systems User Guide 345 FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxUGSystemConfig.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY • The configuration file specified by the line does not exist on the USB key or is corrupted. • The image file specified by the line does not exist on the USB key or is corrupted. – If parsing of the line failed for some other reason, the line is ignored and a SYSLOG message is sent. NOTE: When both Auto-Update and Auto-Configuration are performed, the image file is loaded first, the device is booted and then the configuration file is loaded. Preparations for Using Auto Configuration from a TFTP Server The Auto-Update/Configuration feature enables configuring the device from a configuration file found on the TFTP server. Two methods may be used: • One-file Read, described in "Auto Configuration (One File Read Method)" on page 345. This method is used if a configuration file is found on the TFTP server. • Multi-file Read, described in "Auto Configuration (Multi File Read Method)" on page 346. This method is used if a configuration file name is not found on the DHCP server, or the configuration file is not found on the TFTP server. Auto Configuration (One File Read Method) This method requires the following preparations on the DHCP and TFTP servers: • TFTP Server Place a configuration file, for example config.txt in the main directory. This file can be created by copying a configuration file from a device. When the device is booted this becomes the Running configuration file. • DHCP Server – Configure the DHCP server with option 67 and the name of the configuration file on the TFTP server (for example, config.txt). – Configure the DHCP server with option -20 or 66. This is the IP address of the TFTP server.346 Dell PowerConnect 55xx Systems User Guide FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxUGSystemConfig.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY • Device - On the device, one of the following cases may exist: – If Configuration Auto-Config is selected, the device is configured with the configuration file on the TFTP server only if the Startup configuration file is empty. – If Force Configuration Download at Next Startup is selected, the device is configured with the configuration file on the TFTP server whether the Startup configuration file is not empty or not. Auto Configuration (Multi File Read Method) If the one-file method has failed and the TFTP Server IP address has been provided by the DHCP Server, the switch applies the multi-file method to download the configuration file. The following steps are performed by the switch: • The switch gets the hostname, as described below. – If the hostname was provided by the DHCP server, this hostname is used. – If the hostname has not been provided by a DHCP server, and if the user has configured the sysName variable, its value is used as a hostname. – If neither of the above occurred, the switch uses the fp-net.cfg Filename List on the TFTP server. Each file in this list is a text file containing commands, each of which: • Occupies one line. • Has the following format: ip host hostname ip-addr. Each line maps an IP address to a hostname. When the switch identifies its own IP address in this list, the hostname associated with it is used. • The switch tries to download a configuration file with the following names: – hostname-config – hostname.cfg if the previous file does not exist – host.cfg if the previous files do not existDell PowerConnect 55xx Systems User Guide 347 FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxUGSystemConfig.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY Preparations for Firmware Image Download from TFTP The image file download consists of the following steps: • The switch downloads the Indirect Image File and extracts from it the name of the image file. Note: If the size of the image name bigger than 160 octets only the first 160 octets will be used • If the image file version differs from the current image file version, then the image file is loaded and the switch is rebooted. The preparations on the DHCP and TFTP servers require the following: • TFTP Server – Create a sub directory in the main directory. Place a software image file in it. – Create an indirect file that contains a path and the name of the software version (for example indirect-contax.txt that contains contax\contax-version.ros). – Copy this file to the TFTP server’s main directory • DHCP Server – Configure the DHCP server with option -20 or 66. This is the IP address of the TFTP server. – Configure the DHCP server with option 125. Enter the following information: • A2-02-00-00 — Enterprise Number 674 (Dell PowerConnet 55xx value). It should be written from right to left. 674=02 a2 • 15 — Data Length • 01 — Sub option code 1 (Dell PowerConnet 55xx value) • 13 — Sub option length • Conversion of the file name (in the above example: conversion of indirect-contax.txt from ASCII to HEX - 69-6E-64-69-72-65-63- 74-2D-63-6F-6E-74-61-78-2E-74-78-74348 Dell PowerConnect 55xx Systems User Guide FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxUGSystemConfig.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY Auto Update Configuration through the GUI To set the auto update and configuration parameters: .

It contains the following sections: • sFlow Overview • Workflow • sFlow Receiver Settings • sFlow Interface Settings • sFlow Statistics sFlow Overview The sFlow feature enables collecting statistics using the sFlow sampling technology, based on sFlow V5. This sampling technology is embedded within switches and routers. It provides the ability to continuously monitor traffic flows on some or all the interfaces, simultaneously. The sFlow monitoring system consists of an sFlow agent (embedded in a switch or router or in a stand alone probe) and a central data collector, known as the sFlow receiver. The sFlow agent uses sampling technology to capture traffic and statistics from the device it is monitoring. sFlow datagrams are used to forward the sampled traffic and statistics to an sFlow receiver for analysis. sFlow V5 defines: • How traffic is monitored. • The sFlow MIB that controls the sFlow agent. • The format of the sample data used by the sFlow agent when forwarding data to a central data collector. The device provides support for two types of sFlow sampling: flow sampling and counters sampling. The following counters sampling is performed according to sFlow V5 (if supported by the interface): – Generic interface counters (RFC 2233) – Ethernet interface counters (RFC 2358)376 Dell PowerConnect 55xx Systems User Guide FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxUGSystemConfig.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY Workflow By default, flow and counter sampling are disabled.

Auto-negotiation is enabled on all ports by default. Auto-negotiation is a mechanism established between two link partners to enable a port to advertise its transmission rate, duplex mode and flow control abilities to its partner. Both ports then operate at the highest common denominator. If connecting a Network Interface Card (NIC) that does not support autonegotiation or is not set to auto-negotiation, both the device switching port and the NIC must be manually set to the same speed and duplex mode. If the station, on the other side of the link, attempts to auto-negotiate with a device 100BaseT port that is configured to full duplex, the auto-negotiation results in the station attempting to operate in half duplex. MDI/MDIX The device supports auto-detection of straight-through and crossed cables on all 10/100/1000BaseT ports. This feature is part of auto-negotiation and is enabled when Auto-negotiation is enabled. When the MDI/MDIX (Media Dependent Interface with Crossover) is enabled, the automatic correction of errors in cable selection is possible, thus making the distinction between a straight-through cable and a crossover cable 386 Dell PowerConnect 55xx Systems User Guide FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxUGSwitching_Ports.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY irrelevant. The standard wiring for end stations is known as MDI (Media Dependent Interface), and the standard wiring for hubs and switches is known as MDIX. Flow Control The device supports 802.3x flow control for ports configured to Full Duplex mode. By default, this feature is enabled on all ports, and it can be disabled per port. Flow control creates a lossless link with no packet loss. The flow control mechanism enables the receiving side to signal to the transmitting side that transmission must temporarily be halted to prevent buffer overflow. This signaling is done by sending PAUSE frames. The ports that receives pause frames stops transmitting traffic. Flow control on the device works in Receive-Only mode, meaning that the interfaces with enabled flow control receive PAUSE frames, but do not send them. When flow control is enabled, the system buffers are allocated per port so that if the buffers of one port are consumed, other ports will still have their free buffers. Back Pressure The device supports back pressure for ports configured to Half Duplex mode. By default, this feature is disabled, and it can be enabled per port. The back-pressure mechanism prevents the sender from transmitting additional traffic temporarily. The receiver may occupy a link so it becomes unavailable for additional traffic.

The Green Ethernet feature reduces overall power usage in the following ways: • Energy Efficient Ethernet — When using EEE, systems on both sides of the link can disable portions of their functionality and save power during periods of low link utilization. EEE is a hardware feature that is enabled by default, and is transparent to users. This feature is defined per port, regardless of their LAG membership. • Short-Reach Mode — Power usage is adjusted to the actual cable length. In this mode, the VCT (Virtual Cable Tester) length test is performed to measure cable length. If the cable is shorter than a predetermined length, the switch reduces the power used to send frames over the cable, thus saving energy. This mode is only supported on RJ45 ports. Power savings and current power consumption in Short Reach mode can be monitored. The total amount of saved energy can be viewed as a percentage of the power that would have been consumed by the physical interfaces had they not been running in Green Ethernet mode.Dell PowerConnect 55xx Systems User Guide 391 FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxUGSwitching_Ports.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY The above two energy saving modes must be enabled globally and then configured per port.

This can be used to set up a group of ports that receive similar services. A protected port does not forward traffic (Unicast, Multicast, or Broadcast) to any other protected port on the same switch. A community is a group of protected ports. Protected ports within the same community can forward traffic to each other. The following types of ports can be defined: • Protected Port — Can send traffic only to uplink ports. • Community Port — A protected port that is associated with a community. It can send traffic to other protected ports in the same community and to uplink ports. • Uplink Port — An uplink port is an unprotected port that can send traffic to any port. • Isolated Port — A protected port that does not belong to a community. Port Protection is independent of all other features and configuration settings. Two protected ports in a common VLAN cannot communicate with each other. Protected Port Restrictions The following restrictions apply to protected ports: • When a protected port is placed in a LAG, it loses its protected port attribute and takes upon itself the LAG's protection attributes. When the port is removed from the LAG, its attributes are re-applied. • Mirrored traffic is not subject to protected ports rules. • Routing is not affected by the protected port forwarding rule, so that if a packet enters a protected port, it can be routed by the device to another protected port.Dell PowerConnect 55xx Systems User Guide 395 FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxUGSwitching_Ports.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY Protected Port Configuration To configure protected ports and establish their communities: 1 Click Switching > Ports > Protected Ports in the tree view to display the Protected Ports: Summary page.

After a link is established and optional facilities are negotiated as needed by the LCP, the originating PPP sends Network Control Protocols (NCP) packets to select and configure one or more network layer protocols. 400 Dell PowerConnect 55xx Systems User Guide FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxUGSwitching_Ports.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY When each of the chosen network layer protocols has been configured, packets from each network layer protocol can be sent over the link. The link remains configured for communications until explicit LCP or NCP packets close the link, or until some external event occurs. This is the actual switch port link type. It may differ from the administrative state. • Disable — Disables point-to-point link. • Auto — The device automatically establishes a point-to-point link. – Fast Link — Displays whether Fast Link mode is enabled for the port.

This means that in practice, they are sent to all ports belonging to the relevant VLAN. In this way, one ingress frame is turned into many, creating the potential for a storm. Storm protection provides the ability to limit the number of frames entering the switch, and to define the types of frames that are counted towards this limit. When a threshold (limit) is configured on the device, the port discards traffic when that threshold is reached. The port remains blocked until the traffic rate drops below this threshold.

To monitor traffic, either for information gathering, such as statistical analysis, or for troubleshooting higher-layer protocol operation, the Mirroring feature forwards frames to a monitoring port. Mirroring provides the ability to specify that a desired destination (target) port will receive a copy of all traffic passing through designated source ports. The frames arriving at the destination port are copies of the frames passing through the source port at ingress, prior to any switch action. It is possible to specify several source ports to be monitored by a single target port. However, in this case, the traffic sent to the target port is placed in the target port's queues on a first come, first served basis, and any excess traffic is silently discarded. This may mean that the traffic actually seen by any device attached to the target port is an arbitrarily selected subset of the actual traffic going through the source ports. Port mirroring is only relevant to physical ports. Therefore, if you want a LAG to function as the source of a port mirroring session, the member ports must be individually specified as sources. Up to four sources can be mirrored. This can be any combination of four individual ports. Before configuring Port Mirroring, note the following: • Monitored ports cannot operate faster than the monitoring port. • All Rx/Tx packets should be monitored to the same port. Destination Port Restrictions The following restrictions apply to destination ports: • Destination ports cannot be configured as source ports. • Destination ports cannot be a member of a LAG. • IP interfaces cannot be configured on the destination port. • GVRP cannot be enabled on the destination port. • The destination port cannot be a member of a VLAN. • Only one destination port can be defined.418 Dell PowerConnect 55xx Systems User Guide FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxUGSwitching_Ports.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY • All QoS/CoS rules that apply to the destination port, as an egress, such as traffic shaping, are suspended for the duration of the mirroring session. Any such settings, configured on the port during the mirroring session, take effect only after the port is no longer a destination port for a mirroring session. • Ingress mirrored packets may arrive at the ingress port either with an 802.1q tag or without. When the packets are mirrored to a port analyzer, they should be transmitted as they are received on the ingress port. However, in the device, the packet is transmitted out of the port analyzer as always tagged or always untagged (user configurable), regardless of the input encapsulation. Source Port Restrictions The following restrictions apply to ports specified as source ports: • Source ports cannot be a member of a LAG. • Source ports cannot be configured as a destination port. • Up to four source ports can be mirrored. NOTE: When a port is set to be a target port for a port-mirroring session, all normal operations on it are suspended. This includes Spanning Tree and LACP. All currently active protocols and services on that port are suspended.Dell PowerConnect 55xx Systems User Guide 419 FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxUGSwitching_Ports.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY Port Mirroring To specify source and destination ports for port mirroring: 1 Click Switching > Ports > Port Mirroring in the tree view to display the Port Mirroring: Summary page.

Packets, addressed to a destination stored in one of these tables, are forwarded to the associated port. MAC addresses are dynamically learned when packets arrive at the device. Addresses are associated with ports by learning the source address of the frame. Frames, addressed to a destination MAC address that is not associated with any port, are flooded to all ports of the relevant VLAN. In order to prevent the bridging table from overflowing, dynamic MAC addresses, from which no traffic is seen for a certain period, are erased. Static addresses are manually entered into the table.424 Dell PowerConnect 55xx Systems User Guide FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxUGSwitching_AddressTables.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY Static Addresses Static addresses are manually assigned to a specific interface and VLAN on the switch.

When the destination address for inbound traffic is found in the database, the packets intended for that address are forwarded directly to the associated port. Otherwise, the traffic is flooded to all ports in the VLAN of the frame. To prevent the table from overflowing and to make room for new addresses, an address is deleted from the table if no traffic is received from a dynamic MAC address for a certain period. This period of time is called the aging interval. To configure dynamic addresses: 1 Click Switch > Address Tables > Dynamic MAC Address in the tree view to display the Dynamic Address page.

GARP defines a set of devices interested in a given network attribute, such as VLAN or Multicast address. The Generic Attribute Registration Protocol (GARP) provides a generic framework whereby devices in a bridged LAN, such as end stations and switches, can register and de-register attribute values, such as VLAN Identifiers, with each other. In doing so, these attributes are propagated to devices in the bridged LAN, and these devices form a reachability tree that is a subset of an active topology. GARP defines the architecture, rules of operation, state machines and variables for the registration and deregistration of attribute values. When configuring GARP, ensure the following: • The leave time must be greater than or equal to three times the join time. • The leave-all time must be greater than the leave time. • Set the same GARP timer values on all Layer 2-connected devices. If the GARP timers are set differently on the Layer 2-connected devices, GARP application does not operate successfully.432 Dell PowerConnect 55xx Systems User Guide FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxUGSwitching_GARP.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY GARP Timers To enable a GARP timer on an interface: 1 Click Switching > GARP > GARP Timers in the tree view to open the GARP Timers: Summary page.

STP eliminates loops by providing a unique path between end stations on a network. Loops occur when alternate routes exist between hosts. Loops, in an extended network, can cause bridges to forward traffic indefinitely, resulting in packets not arriving at their destination, increased traffic, and reduced network efficiency. The device supports the following Spanning Tree versions: • Classic STP — Provides a single path between end stations, avoiding and eliminating loops. For more information on configuring Classic STP, see "Global Settings" on page 437. • Rapid STP (RSTP) — Provides faster convergence of the spanning tree than Classic STP. RSTP is most effective when the network topology is naturally tree-structured, and therefore faster convergence might be possible. RSTP is enabled by default. Although Classic STP is guaranteed to prevent Layer 2 forwarding loops, in a general network topology, there might be an unacceptable delay before convergence. This means that before convergence, each bridge or switch in the network must decide if it should actively forward traffic or not, on each of its ports. For more information on configuring Rapid STP, see "Rapid Spanning Tree" on page 450. • Multiple STP (MSTP) — MSTP is based on RSTP. It detects Layer 2 loops, and attempts to mitigate them by preventing the involved port from transmitting traffic. Since loops exist on a per-Layer 2-domain basis, a situation can occur where there is a loop in VLAN A and no loop in VLAN B. If both VLANs are on Port X, and STP wants to mitigate the loop, it stops traffic on the entire port, including VLAN B traffic, where there is no need to stop traffic. Multiple Spanning Tree Protocol (MSTP) solves this problem by enabling several STP instances, so that it is possible to detect and mitigate loops separately in each instance. By associating instances to VLANs, each 436 Dell PowerConnect 55xx Systems User Guide FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxUGSwitching_STP.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY instance is associated with the Layer 2 domain on which it performs loop detection and mitigation. This enables a port to be stopped in one instance, such as traffic from VLAN A that is causing a loop, while traffic can remain active in another domain where no loop was seen, such as on VLAN B. MSTP provides full connectivity for packets allocated to any VLAN, and transmits packets assigned to various VLANs, through different multiple spanning tree (MST) regions. MST regions act as a single bridge. For more information on configuring Multiple STP, see "Multiple Spanning Tree" on page 454.Dell PowerConnect 55xx Systems User Guide 437 FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxUGSwitching_STP.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY Global Settings To enable STP and select the STP mode on the device: 1 Click Switching > Spanning Tree > Global Settings in the tree view to display the Global Settings page.

When each of the chosen network layer protocols has been 452 Dell PowerConnect 55xx Systems User Guide FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxUGSwitching_STP.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY configured, packets from each network layer protocol can be sent over the link. The link remains configured for communications until explicit LCP or NCP packets close the link, or until some external event occurs. This is the actual switch port link type. It may differ from the administrative state. • Disable — Disables point-to-point link. • Auto — The device automatically establishes a point-to-point link. – Point-to-Point Operational Status — Displays the Point-to-Point operating state. – Active Protocol Migration Test — Check to run a Protocol Migration test. This discovers whether the link partner using STP still exists, and if so whether it has migrated to RSTP or MSTP. If it still exists as an STP link, the device continues to communicate with it by using STP. Otherwise, if it has been migrated to RSTP or MSTP, the device communicates with it using RSTP or MSTP, respectively.

For example, all workstations and servers used by a particular workgroup team can be connected to the same VLAN, regardless of their physical connections to the network, or the fact that they might be intermingled with other teams. Reconfiguration of the network can be done through software rather than by physically unplugging and moving devices or wires. A VLAN can be thought of as a Broadcast domain that exists within a defined set of switches. A VLAN consists of a number of end systems, either hosts or network equipment (such as bridges and routers), connected by a single bridging domain. The bridging domain is supported on various pieces of network equipment; for example, LAN switches that operate bridging protocols between them with a separate bridge group for each VLAN. VLANs are created to provide the segmentation services traditionally provided by routers in LAN configurations. VLANs address scalability, security, and network management. Routers in VLAN topologies provide broadcast filtering, security, address summarization, and traffic flow management. None of the switches, within a defined group, will bridge any frames, not even broadcast frames, between two VLANs. 468 Dell PowerConnect 55xx Systems User Guide FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxUGSwitching_VLAN.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY Frame Flow Figure 14-1 describes the flow of VLAN frames from the Ingress port to the Egress port: Figure 14-1. Frame Flow Through a VLAN When a frame is received, it must be assigned a VLAN. VLAN assignment is accomplished by the following steps: 1 If the frame contains a VLAN tag, that tag is used, otherwise the frame is classified by the port's default VLAN (PVID), if it is defined. 2 After classification, the frame may pass (if enabled) through ingress filtering, where the frame is dropped if the frame's VLAN ID is not one of the VLANs to which the ingress port belongs. 3 A forwarding decision is made, as a function of the VLAN ID and the destination MAC address. 4 The egress rules define whether the frame is to be sent as tagged or untagged. Special-case VLANs VLAN#1 and VLAN#4095 are special-case VLANs: • VLAN1 — Defined as the default VLAN, and may only be used as a Ports Default VLAN ID (PVID). This means that if the VLAN, whose VID is the current port's PVID, is deleted from the port (or from the system), that port's PVID is set to 1. VLAN#1 cannot be deleted from the system. • VLAN #4095 — Defined (according to standard and industry practice) as the "discard" VLAN. A frame classified to this VLAN is silently dropped.

The added tag provides a VLAN ID to each customer, which ensures private and segregated network traffic. The VLAN ID tag is assigned to a customer port in the service provider network. The designated port then provides additional services to the packets with the double-tags. This enables administrators to expand service to VLAN users. Port Modes Ports participating in Layer 2 switching may be classified as: • Access Ports Ports set to Access mode belong to a single VLAN, whose VID is the currently set PVID (default =1). These ports accept all untagged frames, and all frames tagged with the VID, currently set as the port's PVID. All traffic is sent untagged. If the VLAN, whose VID is set as the current PVID of the port, is deleted from the system, or deleted from the port, the port's PVID will be set to 1, meaning that the port will be made a member of VLAN#1, the default VLAN. Ingress filtering is always enabled for ports in Access mode. Setting an Access port’s PVID to 4095 effectively shuts it down, as no frames will be transferred in either direction. Access mode ports are intended to connect end-stations to the system, especially when the end-stations are incapable of generating VLAN tags. • Trunk Ports Ports set to Trunk mode may belong to multiple VLANs. The default VLAN membership of a trunk port is all VLANs (1-4094). A PVID must be set on the port (it can be a non-existing VLAN). Trunk ports accept tagged and untagged frames. Untagged frames will be classified to the VLAN whose VLAN ID (VID) is configured as the port’s PVID. Frames, sent from the port in the VLAN, whose VID is the current PVID, are sent untagged. Frames sent in all other VLANs active on the port are sent tagged.470 Dell PowerConnect 55xx Systems User Guide FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxUGSwitching_VLAN.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY Ingress filtering is always enabled on Trunk-mode ports. Incoming frames will undergo ingress filtering, and if correctly tagged, (tagged with a VID of one of the VLANs to which the port currently belongs) are admitted. The default PVID is 1 (the default VLAN). If another VID is configured as the port’s PVID, and the corresponding VLAN is deleted from the port or from the system, the port’s PVID reverts to 1, meaning that the port is made a member of the default VLAN. Setting a trunk-port’s PVID to 4095 limits traffic to tagged frames. Incoming untagged frames are silently discarded, and no frames are sent untagged. Trunk-mode ports are intended for switch-to-switch links, where traffic is usually tagged. • General Ports Ports set to General mode may be members of multiple VLANs. Each of these VLANs may be configured to be tagged or untagged. This setting applies to transmitted frames. Incoming untagged frames are classified into the VLAN whose VID is the currently configured PVID. Ingress filtering may be disabled on General ports. Ingress filtering is enabled by default. • Promiscuous Ports A promiscuous port can communicate with all ports of the same Private VLAN (PVLAN), including the isolated ports of the same PVLAN. • Isolated An isolated port has complete Layer 2 isolation from the other ports within the same PVLAN, but not from the promiscuous ports. Isolated ports can communicate with promiscuous ports. In the factory default configuration, all ports are designated as Access ports, and are associated with the default VLAN.Dell PowerConnect 55xx Systems User Guide 471 FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxUGSwitching_VLAN.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY Acceptable Frame Type The acceptable frame type can be set on a port to accept all frames (tagged and untagged), tagged only, or untagged only.

Protocol-based VLANs Untagged frames received on a VLAN-aware switch can be classified by methods others than source port, such as data-link-layer protocol identification. This classification method is referred to as protocol-based VLANs. Protocol-based VLANs are useful for isolating Layer 2 traffic of various Layer 3 protocols. If, for example, a switch serves IP stations and IPX stations that communicate with a single VLAN-unaware server, without using protocol-based VLANs, all the Layer 2 Broadcast traffic would reach all the stations. With protocol-based VLANs, the switch can forward incoming traffic from the server to stations in a specific VLAN only. Protocol-based VLANs are only available on General ports. Classification rules are set on a per-port basis, and may be sensitive to the frame's encapsulation. The default encapsulation assumed is Ethernet. On each port, a user can define associations between groups of data-link layer protocols and ports. For each group/port combination, the user may set the VLAN to which frames incoming on that port will be classified if they belong to any of the protocols in the group. Several protocol-groups may be associated to a single port, and a protocol group may be assigned to multiple ports, if so desired. It is not guaranteed that the VLAN to which the frame is classified exists in the system, or is active on that port. Restrictions The following frames (packet) types are supported: Ethernet, RFC 1042, and LLC Other. There may be dependencies between protocols and encapsulations, and specifying one protocol may automatically add additional protocols to the protocol-group, such as specifying IP implies ARP and vice-versa.

An example of this is specifying the Ethernet encapsulation, even by default, implies IEEE802 encapsulation, as per RFC 1042. The following standards are relevant: • IEEE802.1V defines VLAN assignment by protocol type. • IETF RFC 10-2 defines a standard for the transmission of IP datagrams over IEEE 802 Networks Defining Protocol Groups Define protocol groups in two steps: 1 Define a protocol group by assigning one or more protocols to the group and giving it a protocol-group ID (any integer), using the Protocol Group pages. 2 Associate the group with a desired VLAN classification, per port, using the Protocol Port pages.486 Dell PowerConnect 55xx Systems User Guide FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxUGSwitching_VLAN.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY To define a protocol group: 1 Click Switching > VLAN > Protocol Group in the tree view to display the Protocol Group: Summary page.

This VLAN is configured with a QoS profile that ensures high voice quality. Equipment, such as VOIP phones, transmits IP traffic with a pre-configured Organizational Unique Identifier (OUI) prefix in the source MAC address. This enables the switch to dynamically identify ports connected to the VoIP equipment and automatically add these ports to the Voice VLAN. IP phones use one of the following modes, both of which are supported by the device: • Use only tagged packets for all communications. • Initially use untagged packets while retrieving the initial IP address through DHCP. Then the phone uses the Voice VLAN and starts sending tagged VoIP packets. Non-VoIP traffic is dropped from the Voice VLAN when the device is in Auto Voice VLAN secured mode. The Voice VLAN feature also provides QoS actions to VoIP, ensuring that the quality of voice does not deteriorate if the IP traffic is received unevenly. To summarize, when Voice VLAN is enabled and configured, and VoIP equipment is connected to one of the switch ports, the VoIP traffic triggers the switch’s Voice VLAN feature to add this port to the Voice VLAN (a VLAN that usually carries only voice traffic), and to assign traffic from this port a specific QoS profile, ensuring high voice quality. The device supports a single voice VLAN.

If the other device ports are also LACP ports, the devices establishes a LAG between them. When you aggregate ports, the ports and LAG must fulfill the following conditions: • All ports within a LAG must be the same media type. • A VLAN is not configured on the port. • The port is not assigned to another LAG. • Auto-negotiation mode is not configured on the port. • The port is in full-duplex mode. • All ports in the LAG have the same ingress filtering and tagged modes. • All ports in the LAG have the same back pressure and flow control modes. • All ports in the LAG have the same priority. • All ports in the LAG have the same transceiver type. • The device supports up to 32 LAGs, and eight ports in each LAG. • Ports can be configured as LACP ports only if the ports are not part of a previously configured LAG.510 Dell PowerConnect 55xx Systems User Guide FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxUGSwitching_LAG.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY Ports added to a LAG lose their individual port configuration. When ports are removed from the LAG, the original port configuration is applied to the ports. The device uses a hash function to assign packets to a LAG member. The hash function statistically load-balances the aggregated link members. The device considers an Aggregated Link to be a single logical port. Aggregate ports can be linked into link-aggregation port-groups. Each group comprises ports with the same speed, set to full-duplex operations. Ports in a LAG can contain different media types if the ports are operating at the same speed. Aggregated links can be manually or automatically configured by enabling LACP on the relevant links.Dell PowerConnect 55xx Systems User Guide 511 FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxUGSwitching_LAG.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY LACP Parameters To define LACP LAGs, configure LACP global and port parameters, such as LACP system priority, timeout, and port priority.

Layer 2 Multicast service is based on a Layer 2 device receiving a single packet addressed to a specific Multicast address. Multicast forwarding creates copies of the packet, and transmits the packets to the relevant ports. There are two types of Multicast groups: • Registered Multicast Group — When traffic addressed to a registered Multicast group is received, it is handled according to its entry in the Multicast Filtering Database and forwarded only to the registered ports. • Unregistered Multicast Group — If traffic addressed to an unregistered Multicast group is received, it is handled by a special entry in the Multicast Filtering Database. The default setting of this is to flood all such traffic (traffic in unregistered Multicast groups). The device supports: • Forwarding L2 Multicast Packets — Forwards Layer 2 Multicast packets. Layer 2 Multicast filtering is enabled by default, and is not user-configurable. • Filtering L2 Multicast Packets — Forwards Layer 2 packets to interfaces. If Multicast filtering is disabled, Multicast packets are flooded to all relevant ports. NOTE: The system supports Multicast filtering for 256 Multicast groups. Layer 2 Switching Layer 2 switching forwards Multicast packets to all relevant VLAN ports by default, managing the packet as a single Multicast transmission. While Multicast traffic forwarding is effective, it is not optimal, as irrelevant ports also receive the Multicast packets. The excess packets cause increased network traffic. Multicast forwarding filters enable forwarding of Layer 2 packets to a subset of ports instead of to all ports.518 Dell PowerConnect 55xx Systems User Guide FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxUGSwitching_Multicast.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY IGMP Internet Group Multicast Protocol (IGMP) adds IGMP packets to Multicast traffic. When IGMP Snooping is enabled globally, all IGMP packets are forwarded to the CPU. The CPU analyzes the incoming packets and determines: • Which ports want to join which Multicast groups. • Which ports have Multicast routers generating IGMP queries. • What routing protocols are forwarding packets and Multicast traffic. Ports requesting to join a specific Multicast group issue an IGMP report, specifying that the Multicast group is accepting members. This results in the creation of an entry in the Multicast filtering database.

The subscribers are the only receivers of the Multicast transmissions. • A Multicast TV VLAN can be defined for an Access port (a port that is in Access mode for VLAN membership). • All static VLANs are permitted to be a Multicast-TV VLAN. • The configuration is performed per port. One or more IP Multicast address groups can be associated with a Multicast VLAN. The source port must belong to the Multicast VLAN. Source and receiver ports do not have to be members of the same VLAN. An end port is defined as a receiver port for the Multicast VLAN. Receiving ports can belong to a single user VLAN and additionally to one Multicast VLAN. The receiver port can be an access member in any VLAN, but not in the defined Multicast VLAN. In Multicast VLAN, the receiver port can only receive traffic and not send traffic on it. Receivers of same Multicast VLAN are isolated in different User (Access port) VLANs and therefore isolated from each other.

LLDP discovers network neighbors by standardizing methods for network devices to advertise themselves to other systems, and to store discovered information. Discovery information includes: • Device identification • Device capabilities • Device configuration The advertising device transmits multiple advertisement message sets in a single LAN packet. The multiple advertisement message sets are sent in the packet’s Type Length Value (TLV) field. LLDP devices must support chassis and port ID advertisements, as well as system name, system ID, system description, and system capability advertisements. LLDP Media Endpoint Discovery (LLDP-MED) increases network flexibility by enabling various IP systems to co-exist on a single network, and provides the following features: • Detailed network topology information, including information on which devices are located on the network and where the devices are located, for example, which IP phone is connect to which port, which software is running on which switch, and which port is connected to which device. • Automatic deployment of policies over networks for: – QoS Policies – Voice VLANs • Emergency Call Service (E-911) via IP phone location information. • Troubleshooting information. LLDP MED sends network managers alerts for: – Port speed and duplex mode conflicts – QoS policy misconfigurations542 Dell PowerConnect 55xx Systems User Guide FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxUGSwitching_LLDP.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY LLDP Properties To enable and configure LLDP: 1 Click System > LLDP > LLDP Properties in the tree view to display the LLDP Properties page.

ARP requests and responses are inspected, and their MAC-address-to-IP-address binding is checked according to the ARP Inspection List defined by the user (in the Dynamic ARP Inspection List and Dynamic ARP Inspection Entries pages). If the packet’s IP address was not found in the ARP Inspection List, and DHCP Snooping is enabled for a VLAN, a search of the DHCP Snooping database is performed. See "How DHCP Snooping Works" on page 573 for an explanation of the DHCP Snooping database. If the IP address is found the packet is valid, and is forwarded. Packets with invalid ARP Inspection bindings are logged and dropped. Ports are classified as follows: • Trusted — Packets are not inspected. • Untrusted —Packets are inspected as described above. The following additional validation checks may be configured by the user: • Source MAC — Compares the packet’s source MAC address in the Ethernet header against the sender’s MAC address in the ARP request. This check is performed on both ARP requests and responses. • Destination MAC — Compares the packet’s destination MAC address in the Ethernet header against the destination interface’s MAC address. This check is performed for ARP responses. • IP Addresses — Compares the ARP body for invalid and unexpected IP addresses. Addresses include 0.0.0.0, 255.255.255.255, and all IP Multicast addresses. 562 Dell PowerConnect 55xx Systems User Guide FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxUGSwitching_ARP.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY Global Settings To enable ARP inspection on the device: 1 Click Switching > Dynamic ARP Inspection > Global Settings in the tree view to display the Global Settings page.

It contains the following topics: • DHCP Snooping Overview • Global Parameters • VLAN Settings • Trusted Interfaces • Snooping Binding Database DHCP Snooping Overview DHCP snooping expands network security by providing layer security between untrusted interfaces and DHCP servers. By enabling DHCP snooping, network administrators can differentiate between trusted interfaces connected to end-users or DHCP Servers, and untrusted interfaces located beyond the network firewall. How DHCP Snooping Works DHCP snooping filters untrusted messages, and stores these messages in a database. Interfaces are untrusted if the packet is received from an interface outside the network, or from an interface beyond the network firewall. Trusted interfaces receive packets only from within the network or the network firewall. The DHCP Snooping Binding database contains the untrusted interfaces’ MAC address, IP address, Lease Time, VLAN ID, and interface information.

It contains the following topics: • DHCP Relay Overview • Option 82 • Global Settings • Interface Settings DHCP Relay Overview The device can act as a DHCP Relay agent that listens for DHCP messages, and relays them between DHCP servers and clients, which reside in different VLANs or IP subnets. This functionality is intended to be used when the client ingress VLAN is different than the VLAN on which DHCP servers are connected. The switch can relay DHCP messages received from its IPv4 interfaces to one or more configured DHCP servers. The switch puts the IPv4 address into the message giaddr before relaying it to the servers. It uses the switch’s IPv4 address of the interface where the message is received. The switch uses the giaddr from the response to determine how to forward the response back to the DHCP client. DHCP Relay must be enabled globally and per VLAN.

Option 82 specifies the relaying switch's MAC address, the port identifier, and the VLAN that forwarded the packet. Both DHCP snooping and DHCP relay can insert option 82 into traversing packets. DHCP snooping with option 82 insertion provides transparent Layer 2 relay agent functionality when the DHCP server is on the same VLAN as the clients. Limitations The following limitations exist for DHCP Relay: • It is not supported on IPv6. • It is not relayed to servers on the client’s VLAN. • Packets that have option-82 information, added by other devices, are discarded. • It does not support Option 82 on non-VLAN interfaces. • It can be enabled only on a VLAN/Port/LAG that has an IP address defined on it.588 Dell PowerConnect 55xx Systems User Guide FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxUGSwitching_DHCP.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY Option 82 To enable Option82 insertion: 1 Click Switching > DHCP Relay > Option 82 in the tree view to display the Option 82 page.

By carrying SCSI commands over IP networks, iSCSI is used to facilitate data transfers over intranets, and to manage storage over long distances. iSCSI can be used to transmit data over local area networks (LANs), wide area networks (WANs), or the Internet, and can enable location-independent data storage and retrieval. Unlike traditional Fiber channels, which requires special-purpose cabling, iSCSI can be run over long distances, using existing network infrastructure. The protocol enables clients (called initiators) to send SCSI commands (CDBs) to SCSI storage devices (targets) on remote servers. This enables organizations to consolidate storage into data center storage arrays, while providing hosts (such as database and web servers) with the illusion of locally-attached disks. The targets listen on a well-known TCP port (or any other TCP port that has been explicitly specified) for incoming connections. The login process is started when the initiator establishes a TCP connection to the desired target, through the TCP port that was explicitly specified. The group of iSCSI TCP connections that link an initiator with a target is called an iSCSI session. When you connect an EqualLogic device to the switch, and iSCSI optimization is enabled, the switch automatically recognizes the port to which the EqualLogic equipment is connected to, and configures the STP Mode to RSTP to support fast network convergence. Optimizing iSCSI iSCSI optimization provides the following features: • Ability to assign a specific QoS profile to the iSCSI flows • Display of iSCSI session details (connections, initiator, target, and so on) • Identification of (self-discovered) iSCSI sessions • Identification of iSCSI session termination • Identification of non-active iSCSI sessions596 Dell PowerConnect 55xx Systems User Guide FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxUGSwitching_iscsi.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY Limitations The following limitations exist: • All iSCSI connections receive the relevant QoS, regardless of whether they are being monitored or not. If, for example, a feature was disabled for some period and was enabled again, it is possible that there are iSCSI TCP connections that were established during this period of time. These cannot be monitored, because all relevant information was already passed at the beginning of the session. But these unidentified sessions will still be assigned to iSCSI QoS. • The maximum number of iSCSI TCP connections, which is also the default setting, is 1K. This can be changed after reset. • The number of iSCSI connections affects other system features. iSCSI-aware, DHCP Snooping, and ACL rules all use the TCAM system resource. If the number of iSCSI connections has been increased, the other application rules (DHCP Snooping or ACL) can be removed after reset. • If the target uses redirect messages upon the initiator request, and, as a result, the initiator opens a connection to a different target, the new target must be configured as part of the general configuration. • Only iSCSI flows to targets that use the iSCSI well-known port or other explicit user-defined configuration are assigned QoS. • The aging configuration works for each connection. The mechanism checks connection activities in a group of 28 TCP iSCSI connections, within the aging time. In the worst case, when the maximum number of 1K TCP connections are monitored and are not terminated gracefully, the mechanism causes inaccuracy, namely, the last 28 TCP iSCSI connections are aged out after (1K/28)*aging-time. • In general, the greater the number of ungracefully terminated iSCSI TCP connections, the greater the inaccuracy is. Not all iSCSI TCP connections are monitored for aging at the same time. Sessions, whose associated TCP connections are not being currently monitored, will show unchanged aging time. • Encryption (Ipsec) must not be applied on iSCSI traffic, otherwise a QoS profile will not be assigned to iSCSI. • iSCSI optimization does not work with IP fragmented frames.Dell PowerConnect 55xx Systems User Guide 597 FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxUGSwitching_iscsi.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY • Each session supports at most four TCP connections. If a new TCP connection of an already opened iSCSI session arrives, and there are already four TCP connections, the new connection replaces the oldest one, within this specific iSCSI session. • A short flow interruption, caused by STP topology change or administrative port-down action, might cause the TCP connection to reinitiate without closing the iSCSI session. If the actual iSCSI session used only one TCP connection, the reinitiated one will be added to the monitoring table, for an aging-time period. After that, it is removed from the list.598 Dell PowerConnect 55xx Systems User Guide FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxUGSwitching_iscsi.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY Global Parameters Use the Global Parameters page to enable iSCSI and to set iSCSI QoS frame priority.

It provides classification of incoming traffic into traffic classes, based on one or more attributes, including: – Device configuration – Ingress interface – Packet contents QoS includes the following features: • Traffic Classification — Classifies each incoming packet, as belonging to a specific traffic flow, based on the packet contents and/or interface. The classification is done by an ACL (Access Control List), and only traffic that meets the ACL criteria is subject to classification. • Assignment to Hardware Queues — Assigns incoming packets to forwarding queues. Packets are sent to a particular queue for handling as a function of the traffic class to which they belong. • Other Traffic Class-Handling Attribute — Applies QoS mechanisms to various classes, including bandwidth management. QoS Modes A single QoS mode is selected and applies to all interfaces in the system. The modes are: • Basic Mode — Class of Service (CoS). – Traffic is divided into classes that determine how it is treated. All traffic in a class is treated with the same QoS action. The QoS action for the class of traffic determines the egress queue on the egress port, based on the indicated QoS value in the incoming frame. The QoS value in the incoming frame is: • Layer 2 Packets — VLAN Priority Tag (VPT) 802.1p value • Layer 3 IPv4 Frames — Differentiated Service Code Point (DSCP) value • Layer 3 IPv6 Frames —Traffic Class (TC) value When operating in Basic mode, the switch trusts this externally-assigned QoS value. 652 Dell PowerConnect 55xx Systems User Guide FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxUGQoS.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY This is the default QoS mode. • Advanced Mode — Per-flow Quality of Service (QoS). In Advanced mode, a per-flow QoS consists of a class map and a policer: – A class map defines the kind of traffic in a flow, and contains one or more ACLs. Packets that match the ACLs belong to the flow. – A policer applies the configured QoS to a flow. The QoS configuration of a flow may consist of the egress queue, the DSCP or CoS value, and actions on out-of-profile (excess) traffic. • Disable Mode (QoS is not enabled) In this mode, all traffic is mapped to a single best-effort queue, so that no type of traffic is prioritized over another. Only a single mode can be active at a time. When the system is configured to work in QoS Advanced mode, settings for QoS Basic mode are not active and vice versa. When the QoS mode is changed, the following occurs: • When changing from Advanced mode to any other mode, policy profile definitions and class maps are deleted. ACLs, which are bonded directly to interfaces, remain bonded. • When changing from Basic mode to Advanced mode, the QoS Trust mode configuration in Basic mode is not retained. • When disabling QoS, the shaper and queue setting (WRR/SP bandwidth settings) are reset to default values. All other user configurations remain intact.Dell PowerConnect 55xx Systems User Guide 653 FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxUGQoS.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY General This section contains the following topics: • QoS Mode • QoS Properties • Queue • Mapping to Queue • Bandwidth • TCP Congestion Avoidance QoS Mode To enable/disable the QoS mode: 1 Click Quality of Service > General >QoS Mode in the tree view to display the QoS Mode page.

The following is an example of the CLI command: Queue The switch supports eight queues for each interface. Queue number eight is the highest priority queue. Queue number one is the lowest priority queue. Traffic Limitation Methods There are two ways of determining how traffic in queues is handled, Strict Priority and Weighted Round Robin (WRR): • Strict Priority — Egress traffic from the highest-priority queue is transmitted first. Traffic from the lower queues is processed only after the highest queue has been transmitted, thus providing the highest level of priority of traffic to the lowest-numbered queue. • Weighted Round Robin (WRR) — In WRR mode, the number of packets sent from the queue is proportional to the weight of the queue (the higher the weight, the more frames are sent). For example, if all eight queues are WRR and the default weights are used, queue 1 receives 1/15 of the bandwidth (assuming all queues are saturated and there is congestion), queue 2 receives 2/15, queue 3 receives 4/15, and queue 8 receives 8/15 of the bandwidth. The type of WRR algorithm used in the device is not the standard Deficit WRR (DWRR), but rather Shaped Deficit WRR (SDWRR). Table 22-2.

When the queuing mode is Weighted Round Robin for all queues, queues are serviced according to their weights. If all queues are assigned strict priority, queues are serviced according to that order. The following is true if some queues are assigned strict priority and others are assigned WRR: • If one queue is assigned strict priority, all higher queues are also assigned strict priority. Conversely, if a queue is assigned a WRR weight, all lower queues must also have a WRR weight assigned to them. • In the above case, traffic for the strict priority queues is always sent before traffic from the WRR queues. Traffic from the WRR queues is forwarded only after the strict priority queues have been emptied. The relative portion from each WRR queue depends on its weight.658 Dell PowerConnect 55xx Systems User Guide FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxUGQoS.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY To select the priority method and enter WRR weights: 1 Click Quality of Service > General > Queue in the tree view to display the Queue page.

It contains the following topics: • Basic Mode Overview • Workflow to Configure Basic Mode • Global Settings • DSCP Rewrite • Interface Settings Basic Mode Overview In QoS Basic mode, a specific domain in the network can be defined as trusted. Within that domain, packets are marked with CoS priority and/or DSCP values, to signal the type of service they require. Nodes within the domain use these fields to assign the packet to a specific output queue. The initial packet classification and marking of these fields is done in the ingress of the trusted domain. Workflow to Configure Basic Mode To configure Basic QoS mode, perform the following: 1 Select Basic mode for the system in the QoS Mode page. 2 Select the trust-behavior in the Global Settings page. 3 If there is any port that, as an exception, should not trust the incoming CoS mark, disable the QoS state on that port in the Interface Settings pages. If a port is disabled without trusted mode, all its ingress packets are forwarded in best effort. It is recommended that you disable the trusted mode at the ports where the CoS and/or DSCP values in the incoming packets are not trustworthy. Otherwise, performance in the network might be negatively affected. 4 If you selected DSCP Rewrite in the Global Settings page, set the DSCP in/out values in the DSCP Rewrite page.670 Dell PowerConnect 55xx Systems User Guide FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxUGQoS.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY Global Settings Use the Global Settings page to enable Trust on all interfaces on the switch.

Changing the DSCP value used in one domain to the DSCP value used in the other domain preserves the priority of traffic used in the first domain. As an example, assume that there are three levels of service: Silver, Gold, and Platinum. The DSCP incoming values used to mark these levels are 10, 20, and 30 respectively. If this traffic is forwarded to another service provider that has the same three levels of service, but uses DSCP values 16, 24, and 48, the values set in the DSCP Rewrite page are used to change the incoming values to the outgoing values.

It contains the following topics: • Advanced Mode Overview • Workflow to Configure Advanced QoS Mode • DSCP Mapping • Class Mapping • QoS Policers • Policy Binding Advanced Mode Overview In Advanced mode, the switch uses policies to support per-flow QoS. A policy and its components have the following characteristics and relationships: • A policy contains one or more class maps. • A class map defines a flow with one or more associated ACLs. Packets that match the ACL rules (ACEs) in a class map with Permit (forward) action, belong to the same flow, and are subject to the same quality of service action. A policy can contain one or more flows, each with a user-defined QoS action. • The QoS of a class map (flow) may be enforced by the associated policer. There are two type of policers, as described in "Defining Class Mapping Using CLI Commands" on page 684. • Per-flow QoS actions are applied to flows by binding the policy maps to the desired ports. A policy map and its class maps can be bound to one or more ports, but each port is bound with, at the most, one policy map. The following points should be considered: • An ACL can be configured to one or more class maps, regardless of policies. • A class map can belong to only one policy map. • When a class map, using a single policer, is bound to multiple ports, each port has its own instance of the policer. Each instance applies the QoS actions on the class map (flow) at a port independent of each other.Dell PowerConnect 55xx Systems User Guide 679 FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxUGQoS.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY • If you bind a policy map to more than one port and one of its classes contains a single policer, all policy map rules will be multiplied per port (using up more TCAM resources). • An aggregate policer applies the QoS to all of its flows in aggregation, regardless of policies and ports. Advanced QoS settings consist of the following elements: • Rules — All frames matching a single group of rules are considered to be a flow. • Actions — To be applied to frames in each flow that match the rules. – Policers — See "Single Policers" on page 689 – Aggregate Policers — "Aggregate Policers" on page 687 – Trust —"Interface Settings" on page 674, "Policy Class Maps" on page 692 – Set DSCP/CoS — "Policy Class Maps" on page 692 – Set Queue — "DSCP Mapping" on page 680 • Binding — Combination of rules and actions that are bound to one or more interfaces. Workflow to Configure Advanced QoS Mode To configure Advanced QoS mode, perform the following: 1 Select Advanced mode for the system in the QoS Mode page. 2 If external DSCP values are different from those used on incoming packets, map the external values to internal values in the DSCP Rewrite page. 3 Create ACLs, as described in "Network Security" on page 97. 4 When ACLs are defined, create class maps and associate the ACLs with them in the Class Mapping pages. 5 Create a policy map in the Policy Class Maps pages, and associate the policy map with one or more class maps. Specify the QoS action, if needed, for example by assigning a policer to a class map, when you associate the class map to the policy.680 Dell PowerConnect 55xx Systems User Guide FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxUGQoS.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY a Single Policer — Create a policy that associates a class map with a single policer in the Policy Table pages and the Class Mapping pages.

This action sends all matching frames to the same policer (aggregate policer), defined in the Aggregate Policer pages. Create a policy that associates a class map with the aggregate policer in the Policy Table pages. 6 Bind the policy to an interface in the Policy Binding pages. DSCP Mapping When a policer is assigned to a class map (flow), you can specify the action to take when the amount of traffic in the flow(s) exceeds the QoS-specified limits. The portion of the traffic that causes the flow to exceed its QoS limit is referred to as out-of-profile packets. If the exceed action is Remark DSCP (as opposed to Drop), the switch rewrites the original DSCP value of the out-of-profile IP packets to a new value, based on the values entered in the DSCP Mapping page. The switch uses the new values to assign resources and egress queues to these packets. The switch physically replaces the original DSCP value in the out-of-profile packets with the new DSCP value. To use the Remark DSCP exceed action, set the DSCP Out value in the DSCP Mapping page. Otherwise the action is null, because the DSCP value in the packet is rewritten to the original DSCP value, set by factory default.Dell PowerConnect 55xx Systems User Guide 681 FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxUGQoS.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY To set new DSCP values: 1 Click Quality of Service > QoS Advanced Mode > DSCP Mapping to display the DSCP Mapping page.

The following is an example of the CLI commands: Class Mapping A Class Map defines a traffic flow associated with ACL(s). A MAC-based ACL, IP-based ACL, and an IPv6-based ACL can be combined into a class map. Class maps are configured to match packet criteria on a match-all or match-any basis. They are matched to packets on a first-fit basis, meaning that the action associated with the first-matched class map is the action performed by the system. Packets that match the same class map belong to the same flow. There are two possible types of matching: • match-all — Traffic matches class map if it matches IP/IPV6 and MAC ACLs • match-any — Traffic matches class map if it matches at least one of the ACLs If a more complex set of rules is needed, several class maps can be grouped into a super-group called a policy (see "Defining Class Mapping Using CLI Commands" on page 684).

This is done by using the ACLs in the class map(s) to match the desired pattern of traffic, and by using a policer to apply QoS on the matching traffic. A policer is configured with a QoS specification. There are two kinds of policers: • Single Policer — A single policer applies the QoS to a single class map, and to a single flow, based on the policer's QoS specification. When a class map, using a single policer, is bound to multiple ports, each port has its own instance of the single policer; each applying the QoS on the class map (flow) at ports that are otherwise independent of each other. A single policer is created in the Policy Table and Policy Class Maps pages. • Aggregate Policer — An aggregate policer applies QoS to one or more class maps, and to one or more flows. An aggregation policer can support class maps from various policies. An aggregate policer applies QoS to all its flow(s) in aggregation, regardless of policies and ports. An aggregate policer is created in the Aggregate Policer pages. An aggregate policer is defined if the policer is to be shared with more than one class. Each policer is defined with its own QoS specification, and is composed of a combination of the following parameters: • Committed Information Rate (CIR) — A maximum allowed rate of traffic, measured in Kbps. • Committed Burst Size (CBS) — An amount of traffic, measured in bytes, which is allowed to pass as a temporary burst, even if it is above the defined maximum rate. • Exceed Action — An action to be applied to frames that are over the limits (called out-of-profile traffic). These frames can be forwarded as is, dropped, or forwarded, after rewriting their DSCP value with a value that marks them as lower-priority frames for all subsequent handling within the device. A policer is assigned to a class map when a class map is added to a policy.Dell PowerConnect 55xx Systems User Guide 687 FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell Contax\sources\CxUGQoS.fm DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY Aggregate Policers To define an aggregate policer: 1 Click Quality of Service > QoS Advanced Mode > Aggregate Policer to display the Aggregate Policer: Summary page.

For more information, see the Dell PowerConnect 5500 Series User Guide, available on your Documentation CD, or check the Dell Support website at support.dell.com/manuals for the latest updates on documentation and software. In this document, the word "switch" refers to either a single switch or a group of stacked switches. For a complete description of the PowerConnect 5500 series switch, see the Dell PowerConnect 5500 Series User Guide, available on your Documentation CD. NOTE: Even though the graphics in this guide show the Dell PowerConnect 5524P device, the instructions are the same for all models. Site Preparation PowerConnect 5500 series switches can be mounted in a standard 48.26-cm (19-inch) equipment rack or placed on a tabletop. Before installing the unit, verify that the chosen location for installation meets the following site requirements: • Power — – The unit is installed near an easily accessible 100-240 VAC, 50-60 Hz outlet. – If a Redundant Power Supply (RPS) or a Modular Power Supply (MPS) is being used, check that it is easily accessible. • Clearance — There is adequate frontal clearance for operator access. Allow clearance for cabling, power connections, and ventilation. ContaxGS.book Page 5 Friday, August 20, 2010 1:53 PM6 Installation • Cabling — The cabling is routed to avoid sources of electrical noise, such as radio transmitters, broadcast amplifiers, power lines, and fluorescent lighting fixtures. • Ambient Requirements — The ambient unit operating temperature range is 0 to 45ºC (32 to 113ºF) at a relative humidity of 10% to 90%, noncondensing. Unpacking Package Contents While unpacking the switch, ensure that the following items are included: • Switch • AC power cable • RS-232 cable with a male 8-pin RJ-45 connector • Self-adhesive rubber pads • Rack-mount kit for rack installation • Documentation CD Unpacking the Switch NOTE: Before unpacking the switch, inspect the package and immediately report any evidence of damage. To unpack the switch: 1 Place the box on a clean flat surface. 2 Open the box or remove the box top. 3 Carefully remove the switch from the box and place it on a secure and clean surface. 4 Remove all packing material. 5 Inspect the switch and accessories for damage. Report any damage immediately to the dealer. ContaxGS.book Page 6 Friday, August 20, 2010 1:53 PMInstallation 7 Installing the Switch The PowerConnect 5500 Series switches can be: • Installed on a rack • Placed on a flat surface Installing in a Rack CAUTION: Disconnect all cables from the unit before mounting the switch in a rack or cabinet. CAUTION: When mounting multiple switches into a rack, mount the switches from the bottom up. To install the switch in a rack: 1 Place the supplied rack-mounting bracket on one side of the switch, ensuring that the mounting holes on the switch line up to the mounting holes on the rack-mounting bracket. Figure 1-1 illustrates where to mount the brackets. Figure 1-1. Bracket Installation for Rack Mounting 2 Insert the supplied screws into the rack-mounting holes and tighten with a screwdriver. ContaxGS.book Page 7 Friday, August 20, 2010 1:53 PM8 Installation 3 Repeat the process for the rack-mounting bracket on the other side of the switch. 4 Insert the unit into the 48.26-cm (19-inch) rack, ensuring that the rack-mounting holes on the switch line up to the mounting holes on the rack. 5 Secure the unit to the rack with the rack screws (not provided). Fasten the lower pair of screws before the upper pair of screws. Ensure that the ventilation holes are not obstructed. Installing on a Flat Surface Install the switch on a flat surface if it is not installed on a rack. The surface must be able to support the weight of the switch and the switch cables. To install the switch on a flat surface: 1 Attach the self-adhesive rubber pads on each marked location on the bottom of the chassis. 2 Set the switch on a flat surface, leaving 5.08 cm (2 inches) on each side and 12.7 cm (5 inches) at the back. 3 Ensure that the switch has proper ventilation. Connecting the Switch to Power Supplies Each switch in the stack must be connected to an AC power supply. The power connectors are positioned on the back panel. Connecting a Redundant Power Supply (RPS) or Modular Power Supply (MPS) is optional, but recommended. The RPS or MPS connector is on the back panel of the switch. The RPS is used for non-PoE switches and MPS is used for PoE switches. Figure 1-2.

Up to eight switches are supported per stack. All stacks must have a Master unit, and may have a Master Backup unit. All other switches are connected to the stack as members (slaves). Stacking Switches PowerConnect 5500 series switches use two HDMI 10G ports for stacking. To connect the switches in the stack: 1 Insert one end of an HDMI cable into the left-hand HDMI port on the switch at the top of the stack and the other end into the right-hand HDMI port of the switch immediately below it. 2 Repeat this process until all switches are connected. 3 (Optional) Connect the left-hand HDMI port of the switch at the bottom of the stack to the right-hand HDMI port of the switch at the top of the stack. This step provides increased bandwidth and redundancy. ContaxGS.book Page 9 Friday, August 20, 2010 1:53 PM10 Stacking Figure 2-1 shows this process. Figure 2-1.

Figure 2-2 describes the stacking LEDs on the front panel of the switch. Figure 2-2. Stacking LEDs on Front Panel The Unit ID of each switch can be either automatically assigned or manually assigned, as described below. Automatic Assignment When you power-up the stack, each switch is assigned a unique Unit ID. This is displayed on the front panel of the switch, as shown in Figure 2-2. The switch that is assigned Unit ID 1 is the Master unit, by default. The switch that is assigned Unit ID 2 is the Master Backup unit. Unit ID Master ContaxGS.book Page 11 Friday, August 20, 2010 1:53 PM12 Stacking Manual Assignment To assign unit IDs to the switches in the stack, do the following for each switch in the stack: 1 Connect the switch to the terminal, as described in "Connecting the Switch to the Terminal". 2 Turn on the switch to begin auto boot and press Return or Esc to abort and enter the Start Up menu. 3 Select Stack menu to open the Stack Menu. 4 Select Set unit stack id. Enter either a Unit ID or 0. 0 indicates that the unit ID will be assigned automatically. NOTE: The entire stack should be installed, as shown in Figure 2-1, before powering up the switches.

Configuration Work Flow To configure the switches: 1 For each switch in the stack: a Connect it to a terminal, as described in the "Connecting the Switch to the Terminal". b Boot the switch, as described in the "Booting the Switch". c Assign a unit ID to the switch, as described in "Unit ID Assignment". 2 Connect the units in the stack to each other, as described in "Configuring the Stack". 3 Connect the Master unit to the terminal, reboot the unit and the Setup Wizard is run automatically, as described in "Configuration Using the Setup Wizard". 4 Respond to the Setup Wizard prompts. 5 Continue managing the switch, either through the console or Telnet, using the CLI or the web GUI, as described in the Dell PowerConnect 5500 Series User Guide. ContaxGS.book Page 13 Friday, August 20, 2010 1:53 PM14 Configuring the Switch Connecting the Switch to the Terminal The switch is configured and monitored through a terminal desktop system that runs terminal emulation software. The switch connects to the terminal through the console port. To connect the switch to a terminal: 1 Connect an RS-232 cable to a VT100-compatible terminal or the serial connector of a desktop system running terminal emulation software. 2 Connect the RS-232 cable to the switch console port on the front panel of the switch (see Figure 3-1) using an 8-pin RJ-45 male connector. Figure 3-1. Front-Panel Console Port 3 Set the terminal emulation software as follows: a Select the appropriate serial port to connect to the switch. b Set the data rate to 9600 baud. c Set the data format to 8 data bits, 1 stop bit, and no parity. d Set Flow Control to none. e Select VT100 for Emulation mode within your communication software. f Select Terminal keys for Function, Arrow, and Ctrl keys. Ensure that the setting is for Terminal keys (not Windows keys). NOTE: You can connect a console to the console port on any unit in the stack, but stack management is performed only from the stack master (Unit ID 1 or 2). Console Port ContaxGS.book Page 14 Friday, August 20, 2010 1:53 PMConfiguring the Switch 15 Booting the Switch After the local terminal is connected, turn on power. The switch then goes through power-on self-test (POST). POST runs every time the switch is started and checks hardware components, to determine if the switch is operational before completely booting. If the system detects a critical problem, the boot process stops. If POST passes successfully, a valid executable image is loaded into RAM. POST messages are displayed on the terminal and indicate test success or failure. The boot process runs for approximately 40-45seconds. When the boot process completes, the following LEDs are lit, as shown in Figure 3-2: • Power • Status • Fan (should be green) • RPS (if it is being used) Figure 3-2. Initial LEDs Power Status Fan RPS ContaxGS.book Page 15 Friday, August 20, 2010 1:53 PM16 Configuring the Switch Configuring the Stack The switch is always considered to be a stack of switches even if the stack only contains a single switch. If there is more than one switch in the stack, each switch must be configured individually. See "Unit ID Assignment" for instructions on how to configure the stack. Configuration Using the Setup Wizard The Setup Wizard guides you through the initial switch configuration to get the system up and running as quickly as possible. Note that you can skip the Setup Wizard and configure the switch manually through the CLI. The Setup Wizard configures the following fields: • SNMP Community String and SNMP Management System IP address (optional) • Username and password • Management switch IP address • IP subnet mask • Default gateway IP address NOTE: The Setup Wizard assumes the following: • The PowerConnect switch was never configured before and is in the same state as when you received it. • The PowerConnect switch booted successfully. • The console connection is established and the console prompt is displayed on the screen of a VT100 terminal switch. Connect the Master unit to a terminal. You can identify the Master unit by the illuminated Master LED on the front panel of the switch (see Figure 2-2). To configure the system using the Setup Wizard: 1 Obtain the following information from the network administrator: • SNMP Community String and SNMP Management System IP address (optional) • Username and password ContaxGS.book Page 16 Friday, August 20, 2010 1:53 PMConfiguring the Switch 17 • The IP address to be assigned to the VLAN 1 interface through which the switch is to be managed (by default, every external and internal port is a member of the VLAN 1) • The IP subnet mask for the network • The default gateway (next hop router) IP address for configuring the default route 2 Boot the Master unit. The system automatically prompts you to use the Setup Wizard.

Seule exception, l'option External Hot Key (Touche rapide externe), que vous pouvez désactiver ou activer via le programme de configuration du système uniquement. Pour plus d'informations sur la configuration des fonctions de votre système d'exploitation, reportez-vous au Centre d'aide et de support Windows. Pour accéder au Centre d'aide et de support, reportez-vous à la page 14. Les écrans de configuration du système affichent les informations sur la configuration courante et les paramètres de votre ordinateur, par exemple : • Configuration du système • Paramètres de configuration de base des périphériques • Paramètres de sécurité du système et mot de passe de disque dur • Paramètres de gestion de l'alimentation • Paramètres de configuration d'amorçage (démarrage) et d'affichage • Paramètres de la station d'accueil • Paramètres de contrôle sans fil AVIS : Ne modifiez les paramètres du programme de configuration du système que si vous êtes un utilisateur expérimenté en informatique ou si vous êtes assisté par un représentant du support technique de Dell. Certaines modifications risquent de provoquer un mauvais fonctionnement de l'ordinateur. Affichage de l'écran de configuration du système 1 Mettez votre ordinateur sous tension (ou redémarrez-le). 2 Lorsque le logo DELL™ apparaît, appuyez immédiatement sur . Si vous attendez trop longtemps et que le logo Windows apparaît, attendez encore jusqu'à ce que le bureau Windows s'affiche. Ensuite, arrêtez votre ordinateur et faites une nouvelle tentative. Programme de configuration du système L'écran de configuration du système se compose de trois fenêtres d'information. La fenêtre de gauche contient une hiérarchie développable des catégories de contrôle. Si vous sélectionnez (mettez en surbrillance) une catégorie (comme Système, Périphériques intégrés ou Vidéo) et que vous appuyez sur , vous pouvez afficher ou masquer les sous-catégories connexes. La fenêtre de droite contient des informations sur la catégorie ou sous-catégorie sélectionnée dans la fenêtre de gauche. 166 Annexe La fenêtre du bas vous indique comment contrôler les fonctions des touches du programme de configuration du système. Utilisez ces touches pour sélectionner une catégorie, modifier les paramètres, ou quitter le programme de configuration du système. Options fréquemment utilisées Certaines options nécessitent le redémarrage de l'ordinateur pour que les nouveaux paramètres entrent en vigueur. Modification de la séquence d'amorçage La séquence d'amorçage, ou ordre de démarrage, indique à l'ordinateur où chercher pour trouver le logiciel requis pour démarrer le système d'exploitation. Vous pouvez contrôler la séquence d'amorçage et activer/désactiver les périphériques à l'aide de la page Ordre d'amorçage du programme de configuration du système. REMARQUE : Pour modifier la séquence d'amorçage sur une base ponctuelle, reportez-vous à la section « Exécution d'un amorçage ponctuel » à la page 167. Cette page affiche la liste générale des périphériques amorçables pouvant être installés sur l'ordinateur, notamment les suivants : • Lecteur de disquette • Unité de disque dur interne • Périphérique de stockage USB • Lecteur de CD/DVD/CD-RW • Disque dur de la baie modulaire REMARQUE : Seuls sont amorçables les périphériques précédés d'un numéro. Pendant la procédure d'amorçage, l'ordinateur commence par le début de la liste, puis analyse chacun des périphériques activés à la recherche des fichiers de démarrage du système d'exploitation. Lorsque les fichiers ont été trouvés, l'ordinateur arrête la recherche et fait démarrer le système d'exploitation. Pour définir les périphériques d'amorçage, sélectionnez (mettez en surbrillance) un périphérique en appuyant sur les touches fléchées haut ou bas, puis activez ou désactivez le périphérique ou modifiez son ordre dans la liste. • Pour activer ou désactiver un périphérique, sélectionnez-le et appuyez sur la barre d'espacement. Les éléments activés sont précédés d'un numéro ; ceux qui ne le sont pas ne sont pas précédés d'un numéro. • Pour modifier l'ordre d'un périphérique dans la liste, sélectionnez-le et appuyez sur (h) ou (b) pour déplacer le périphérique vers le haut ou le bas. Les modifications que vous apportez à la séquence d'amorçage sont prises en compte dès que vous les enregistrez et que vous quittez le programme de configuration du système.Annexe 167 Exécution d'un amorçage ponctuel Vous pouvez définir une séquence d'amorçage ponctuelle sans devoir passer par le programme de configuration du système. (Vous pouvez également utiliser cette procédure pour initialiser Dell Diagnostics sur la partition de l'utilitaire de diagnostics de votre disque dur.) 1 Arrêtez l'ordinateur à l'aide du menu Démarrer. 2 Connectez l'ordinateur à une prise secteur. 3 Allumez l'ordinateur. Lorsque le logo DELL apparaît, appuyez immédiatement sur . Si vous attendez trop longtemps et que le logo Windows apparaît, attendez encore jusqu'à ce que le bureau Windows s'affiche.
