The CLI commands described in this document are organized according to feature groups in separate sections. This section describes how to use the CLI. It contains the following topics: • CLI Command Modes • Starting the CLI • CLI Command Conventions • Entering Commands CLI Command Modes To configure devices, the CLI is divided into various command modes. Each command mode has its own set of specific commands. Entering a question mark "?" at the console prompt displays a list of commands available for that particular command mode. A specific command, which varies from mode to mode, is used to navigate from one mode to another. The standard order to access the modes is as follows: User EXEC mode, Privileged EXEC mode, Global Configuration mode, and Interface Configuration modes. When starting a session, the initial mode for non-privileged users is the User EXEC mode. Only a limited subset of commands is available in the User EXEC mode. This level is reserved for tasks that do not change the configuration. 34 FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\CLI Folders\Dell Contax CLI\files\CLI_Preface.fm D E L L C O N F I D E N T I A L – P R E L I M I N A R Y 9 / 1 2 / 1 2 - F O R P R O O F O N LY Privileged users enter the Privileged EXEC mode directly using a password. This mode provides access to the device Configuration modes. The modes are described below. User EXEC Mode After logging into the device, the user is automatically in User EXEC command mode unless the user is defined as a privileged user. In general, the User EXEC commands enable the user to perform basic tests, and display system information. The user-level prompt consists of the device "host name" followed by the angle bracket (>). console> The default host name is "console" unless it has been changed using the hostname command in the Global Configuration mode. Privileged EXEC Mode Privileged access is password-protected to prevent unauthorized use, because many of the privileged commands set operating system parameters: The password is not displayed on the screen and is case sensitive. Privileged users enter directly into the Privileged EXEC mode. Use disable to return to the User EXEC mode. Global Configuration Mode Global Configuration mode commands apply to features that affect the system as a whole, rather than just a specific interface. To enter the Global Configuration mode, enter configure in the Privileged EXEC mode, and press . The Global Configuration mode prompt is displayed. console(config)# Use exit, end or ctrl/z to return to the Privileged EXEC mode. Interface Configuration Modes Commands in the following modes perform specific interface operations:35 FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\CLI Folders\Dell Contax CLI\files\CLI_Preface.fm D E L L C O N F I D E N T I A L – P R E L I M I N A RY 9 / 1 2 / 1 2 - F O R P R O O F O N LY • Line Interface — Contains commands to configure the management connections. These include commands such as line speed, timeout settings, etc. The Global Configuration mode command line is used to enter the Line Configuration command mode. • VLAN Database — Contains commands to create a VLAN as a whole. The Global Configuration mode command vlan database is used to enter the VLAN Database Interface Configuration mode. • Management Access List — Contains commands to define management access-lists. The Global Configuration mode command management access-list is used to enter the Management Access List Configuration mode. • Port Channel — Contains commands to configure port-channels, for example, assigning ports to a VLAN or port-channel. The Global Configuration mode command interface port-channel is used to enter the Port Channel Interface Configuration mode. • SSH Public Key-Chain — Contains commands to manually specify other device SSH public keys. The Global Configuration mode command crypto key pubkey-chain ssh is used to enter the SSH Public Key-chain Configuration mode. • Interface — Contains commands that configure the interface. The Global Configuration mode command interface is used to enter the Interface Configuration mode. Starting the CLI The switch can be managed over a direct connection to the switch console port, or via a Telnet connection. The switch is managed by entering command keywords and parameters at the prompt. Using the switch CLI commands is similar to entering commands on a UNIX system. If access is via a Telnet connection, ensure the device has an IP address defined, corresponding management access is granted, and the workstation used to access the device is connected to the device prior to using CLI commands. Accessing the CLI from the Console Line 1. Start the device and wait until the startup procedure is complete. The User Exec mode is entered, and the prompt "console>" is displayed. 36 FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\CLI Folders\Dell Contax CLI\files\CLI_Preface.fm D E L L C O N F I D E N T I A L – P R E L I M I N A R Y 9 / 1 2 / 1 2 - F O R P R O O F O N LY 2. Configure the device and enter the necessary commands to complete the required tasks. 3. When finished, exit the session with the quit or exit command. Accessing the CLI from Telnet 1. Enter telnet and the IP address of the device. A User Name prompt is displayed. 2. Enter the User Name and Password. You are in the Privileged Exec mode. 3. Configure the device and enter the necessary commands to complete the required tasks. 4. When finished, exit the session with the quit or exit command. When another user is required to log onto the system, the login command is entered in the Privileged EXEC command mode,. This effectively logs off the current user and logs on the new user. CLI Command Conventions The following table describes the command syntax conventions. Conventions Description [ ] In a command line, square brackets indicates an optional entry. { } In a command line, curly brackets indicate a selection of compulsory parameters separated by the | character. One option must be selected. For example: flowcontrol {auto|on|off} means that for the flowcontrol command either auto, on or off must be selected. Italic font Indicates a parameter. Any individual key on the keyboard. For example click . Ctrl+F4 Any combination keys pressed simultaneously on the keyboard.37 FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\CLI Folders\Dell Contax CLI\files\CLI_Preface.fm D E L L C O N F I D E N T I A L – P R E L I M I N A RY 9 / 1 2 / 1 2 - F O R P R O O F O N LY Entering Commands A CLI command is a series of keywords and arguments. Keywords identify a command, and arguments specify configuration parameters. For example, in the command "show interfaces status gi1/0/5" show, interfaces and status are keywords, gi is an argument that specifies the interface type, and 1/0/5 is an argument that specifies the port. To enter commands that require parameters, enter the required parameters after the command keyword. For example, to set a password for the administrator, enter: console(config)# username admin password smith Help information can be displayed in the following ways: • Keyword Lookup — The character ? is entered in place of a command. A list of all valid commands and corresponding help messages are displayed. • Partial Keyword Lookup — A command is incomplete and the character ? is entered in place of a parameter. The matched parameters for this command are displayed. The following describes features that assist in using the CLI: Terminal Command Buffer Every time a command is entered in the CLI, it is recorded on an internally managed Command History buffer. Commands stored in the buffer are maintained on a First In First Out (FIFO) basis.These commands can be Screen Display Indicates system messages and prompts appearing on the console. all When a parameter is required to define a range of ports or parameters and all is an option, the default for the command is all when no parameters are defined. For example, the command interface range port-channel has the option of either entering a range of channels, or selecting all.

This buffer is not preserved across device resets. The keys that can be used to access the history buffer are described in Table 1. By default, the history buffer system is enabled, but it can be disabled at any time. For information about the command syntax to enable or disable the history buffer, see the history command. There is a standard default number of commands that are stored in the buffer. The standard number of 10 commands can be increased to 256. By configuring 0, the effect is the same as disabling the history buffer system. For information about the command syntax for configuring the command history buffer, see the history size command. To display the history buffer, see show history command. Negating the Effect of Commands For many configuration commands, the prefix keyword "no" can be entered to cancel the effect of a command or reset the configuration to the default value. This guide describes the negation effect for all applicable commands. Command Completion If the command entered is incomplete, invalid, or has missing or invalid parameters, an appropriate error message is displayed. To complete an incomplete command, press the button. If the characters already entered are not enough for the system to identify a single matching command, press "?" to display the available commands matching the characters already entered. Incorrect or incomplete commands are automatically re-entered next to the cursor. If a parameter must be added, the parameter can be added to the basic command already displayed next to the cursor.

Any full match of a keyword, even if it is part of a large string, is considered a match and replaced by the corresponding value. Some macros might contain keywords that require a parameter value. You can use the macro apply macro-name command to display a list of any required values in the macro. If you apply a macro without entering the keyword values, the commands are invalid and are therefore not applied. When you apply a macro to an interface, the macro name is automatically added to the interface. You can display the applied commands and macro names by using the show running-configuration interface interface-id user EXEC mode command. A macro applied to an interface range behaves the same way as a macro applied to a single interface. When a macro is applied to an interface range, it is applied sequentially to each interface within the range. If a macro command fails on one interface, it is nonetheless applied to the remaining interfaces.

Syntax ping [ip] {ipv4-address | hostname} [size packet_size] [count packet_count] [timeout time_out] ping ipv6 {ipv6-address | hostname} [size packet_size] [count packet_count] [timeout time_out] Parameters • ip—Use IPv4 to check the network connectivity. • ipv6—Use IPv6 to check the network connectivity. • ipv4-address—IPv4 address to ping. • ipv6-address—Unicast or multicast IPv6 address to ping. When the IPv6 address is a Link Local address (IPv6Z address), the outgoing interface name must be specified. Refer to the User Guidelines for the interface name syntax. • hostname—Hostname to ping (160 characters. Maximum label size: 63.) • packet_size—Number of bytes in the packet not including the VLAN tag. The default is 64 bytes. (IPv4:64-1518, IPv6: 68-1518) • packet_count—Number of packets to send, from 1 to 65535 packets. The default is 4 packets. If 0 is entered, it pings until stopped (0–65535). • time-out—Timeout in milliseconds to wait for each reply, from 50 to 65535 milliseconds. The default is 2000 milliseconds (50–65535).72 System Management Commands FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\CLI Folders\Dell Contax CLI\files\System_Management.fm D E L L C O N F I D E N T I A L – P R E L I M I N A R Y 9 / 1 2 / 1 2 - F O R P R O O F O N LY Command Mode EXEC mode User Guidelines Press Esc to stop pinging. Following are sample results of the ping command: • Destination does not respond—If the host does not respond, a “no answer from host” appears within 10 seconds. • Destination unreachable—The gateway for this destination indicates that the destination is unreachable. • Network or host unreachable—The switch found no corresponding entry in the route table. The format of an IPv6Z address is: % • interface-name = vlan | ch | isatap | | 0 • integer = | • decimal-number = 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 • physical-port-name = Designated port number, for example gi1/0/1 When using the ping ipv6 command to check network connectivity of a directly attached host using its link local address, the egress interface may be specified in the IPv6Z format. If the egress interface is not specified, the default interface is selected. Specifying interface zone=0 is equivalent to not defining an egress interface. When using the ping ipv6 command with MC address, the information displayed is taken from all received echo responses.

(Range: Valid IP address) • ipv6-address—IPv6 address of the destination host. • hostname—Hostname of the destination host. (Range: 1–160 characters. Maximum label size: 63.) • packet_size—Number of bytes in the packet not including the VLAN tag. The default is 64 bytes. (IPv4:64-1518, IPv6: 68-1518) • ttl max-ttl—The largest TTL value that can be used. The default is 30. The traceroute command terminates when the destination is reached or when this value is reached. (Range: 1–255) • count packet_count—The number of probes to be sent at each TTL level. The default count is 3. (Range: 1–10) • timeout time_out—The number of seconds to wait for a response to a probe packet. The default is 3 seconds. (Range: 1–60) • source ip-address—One of the interface addresses of the device to use as a source address for the probes. The device will normally pick what it feels is the best source address to use. (Range: Valid IP address) • tos tos—The Type-Of-Service byte in the IP Header of the packet.(Range: 0—255) Command Mode EXEC mode User Guidelines The traceroute command works by taking advantage of the error messages generated by routers when a datagram exceeds its time-to-live (TTL) value. The traceroute command starts by sending probe datagrams with a TTL value of one. This causes the first router to discard the probe datagram and send back an error message. The traceroute command sends several probes at each TTL level and displays the round-trip time for each. 76 System Management Commands FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\CLI Folders\Dell Contax CLI\files\System_Management.fm D E L L C O N F I D E N T I A L – P R E L I M I N A R Y 9 / 1 2 / 1 2 - F O R P R O O F O N LY The traceroute command sends out one probe at a time. Each outgoing packet can result in one or two error messages. A "time exceeded” error message indicates that an intermediate router has seen and discarded the probe. A "destination unreachable" error message indicates that the destination node has received the probe and discarded it because it could not deliver the packet. If the timer goes off before a response comes in, the traceroute command prints an asterisk (*). The traceroute command terminates when the destination responds, when the maximum TTL is exceeded, or when the user interrupts the trace with Esc. The traceroute command is not relevant to IPv6 link local addresses. Example Router> traceroute ip umaxp1.physics.lsa.umich.edu Type Esc to abort.

The group defines the objects available to the community. (Range: 1–30 characters) • type router—Specifies that SNMP requests for duplicate tables configure the router tables. This is the default. • type oob—Specifies that SNMP requests for duplicate tables configure the oob tables. Default No community is defined Command Mode Global Configuration mode User Guidelines You can’t specify view-name for su, which has access to the whole MIB. You can use the view-name to restrict the access rights of a community string. The logical key of the command is the pair (community, ip-address). If ipaddress is omitted then the key is (community, All-Ips). By specifying the view-name parameter, the software: • Generates an internal security-name. • Maps the internal security-name for SNMPv1 and SNMPv2 security models to an internal group-name. • Maps the internal group-name for SNMPv1 and SNMPv2 security models to view-name (read-view and notify-view always, and for rw for write-view also), You can use the group-name to restrict the access rights of a community string. By specifying the group-name parameter the software: • Generates an internal security-name. • Maps the internal security-name for SNMPv1 and SNMPv2 security models to the group-name.162 SNMP Commands FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\CLI Folders\Dell Contax CLI\files\SNMP.fm D E L L C O N F I D E N T I A L – P R E L I M I N A R Y 9 / 1 2 / 1 2 - F O R P R O O F O N LY The snmp-server community-group command and snmp-server user command for v1 and v2 are equivalent. You should use the snmp-server community-group command when you want to configure the ipv4-address| ipv6-address management addresses. The Type keyword is used for a different purpose. Therefore, when defining an SNMP community, the administrator must indicate which tables are being configured. If Type is router, it means that the device's tables are being configured. Example snmp-server community ========================== console(config)# snmp-server community abcd su 1.1.1.121 mask 255.0.0.0 console(config)# snmp-server community-group tom abcd 1.1.1.122 prefix 8 snmp-server view The snmp-server view Global Configuration mode command creates or updates a Simple Network Management Protocol (SNMP) server view entry.

When you enter a show running-config command, you do not see a line for this user. To see if this user has been added to the configuration, type the show snmp user command. An SNMP EngineID should be defined in order to add users to the device. Changing or removing the value of snmpEngineID deletes the SNMPv3 users’ database. The logical key of the command is Username. Configuring a remote host is required in order to send informs to that host. A configured remote host is also able to manage the device (besides getting the informs) To configure a remote user, specify the IP address for the remote SNMP agent of the device where the user resides. Also, before you configure remote users for a particular agent, configure the SNMP engine ID, using the snmp-server engineID remote command. The remote agent's SNMP engine ID is needed when computing the authentication and privacy digests from the password.

Replace a single sub-identifier with the asterisk (*) wildcard to specify a subtree family; for example, 1.3.*.4. • included—Specifies that the filter type is included. • excluded—Specifies that the filter type is excluded. Default Configuration No view entry exists. Command Mode Global Configuration mode User Guidelines This command can be entered multiple times for the same filter record. If an object identifier is included in two or more lines, later lines take precedence. The command's logical key is the pair (filter-name, oid-tree). Example The following example creates a filter that includes all objects in the MIB-II system group except for sysServices (System 7) and all objects for interface 1 in the MIB-II interfaces group.

The default is 15 seconds. The parameter is relevant only for informs. (Range: 1–300) • retries retries—Maximum number of times to resend an inform request, when a response is not received for a generated message. The default is 3. The parameter is relevant only for informs. (Range: 0–255) Command Mode Global Configuration mode User Guidelines The logical key of the command is the pair (ip-address/hostname, traps/informs, version). When configuring snmp v1 or v2 notifications recipient the software would automatically generate a notification view for that recipient for all the MIB. (.For SNMPv3 the software doesn’t automatically create a user nor a notify view. Use the commands snmp-server user, snmp-server group and snmpserver view in Global Configuration mode to create a user, a group or a notify group respectively. The format of an IPv6Z address is: % interface-name = vlan | ch | isatap | | 0 integer = | decimal-number = 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 physical-port-name = Designated port number, for example 1/0/16 If the egress interface is not specified, the default interface is selected. Specifying interface zone=0 is equal to not defining an egress interface.

Use the no form of this command to remove the configured engine ID. Syntax snmp-server engineID local {engineid-string | default} no snmp-server engineID local Parameters • engineid-string—Specifies a concatenated hexadecimal character string identifying the engine ID. Each byte in a hexadecimal character string is two hexadecimal digits. Bytes are separated by a period or colon. If an odd number of hexadecimal digits are entered, the system automatically prefixes the digit 0 to the string. (Length: 5–32 characters, 9–64 hexadecimal digits) • default—Specifies that the engine ID is created automatically based on the device MAC address. Default Configuration The engine ID is not configured. If SNMPv3 is enabled using this command, and the default is specified, the default engine ID is defined per standard as: • First 4 octets: First bit = 1, the rest is IANA Enterprise number = 674. • Fifth octet: Set to 3 to indicate the MAC address that follows. • Last 6 octets: The device MAC address. Command Mode Global Configuration mode User Guidelines To use SNMPv3, specify an engine ID for the device. Any ID can be specified or use a default string, which is generated using the device MAC address.172 SNMP Commands FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\CLI Folders\Dell Contax CLI\files\SNMP.fm D E L L C O N F I D E N T I A L – P R E L I M I N A R Y 9 / 1 2 / 1 2 - F O R P R O O F O N LY As the EngineID should be unique within an administrative domain, the following guidelines are recommended: • For standalone devices, use the default keyword to configure the Engine ID. • For stackable systems, configure an EngineID, and verify that it is unique within the administrative domain. Changing or removing the value of snmpEngineID deletes the SNMPv3 users database. The SNMP EngineID cannot be all 0x0 or all 0xF or 0x000000001 Example The following example enables SNMPv3 on the device and sets the device local engine ID to the default value. Console(config)# snmp-server engineID local default snmp-server engineID remote To specify the Simple Network Management Protocol (SNMP) engine ID of a remote SNMP device, use the snmp-server engineID remote Global Configuration mode command.

Command Mode Interface Configuration mode (Ethernet) User Guidelines When short-reach Mode is enabled and is not forced, the VCT (Virtual Cable Tester) length check must be performed. The VCT length check can be performed only on a copper port operating at a speed of 1000 Mbps. If the media is not copper or the link speed is not 1000 Mbps and short-reach mode is not forced (by green-ethernet short-reach force), short-reach mode is not applied. When the interface is set to enhanced mode, after the VCT length check has completed and set the power to low, an active monitoring for errors is done continuously. In the case of errors crossing a certain threshold, the PHY will be reverted to long reach.

Command Mode Global Configuration mode User Guidelines Note that the automatic cable length measurement accuracy is +-10 meters. i.e. a cable with a real length of 30 m may be evaluated in the range of 20m–40m. Length performance depends on the link partner signal quality, cable quality and whether link partner also operates in short-reach mode.382 Green Ethernet FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\CLI Folders\Dell Contax CLI\files\750_Green_Ethernet.fm D E L L C O N F I D E N T I A L – P R E L I M I N A R Y 9 / 1 2 / 1 2 - F O R P R O O F O N LY The recommended default is 50m, as recommended by Marvell PHY team for any cable type. see appendix However, Marvell tests show that link partner can operate error free with an up to 80 m cable (cat 5e).

The analyzer port for port ingress traffic mirroring should be the same port for all mirrored ports. The analyzer port for port egress traffic mirroring should be the same port for all mirrored ports. Following are restrictions apply for ports that are configured to be source ports: • The port cannot be a destination port. The following restrictions apply to ports that are configured to be monitor ports: • The port can’t be source port. • The port isn’t member in port-channel. • IP interface is not configured on the port. • GVRP is not enabled on the port. • The port is not a member in any VLAN, except for the default VLAN (will be automatically removed from the default VLAN). • L2 protocols are not active on the copy dest. Port: LLDP, LBD, STP, LACP. The following restrictions apply to ports that are configured to be monitor ports: • The port cannot be source port. • The port is not a member in port-channel. Notes: • In this mode some traffic duplication on the analyzer port may be observed. For example: • Port 2 is being egress monitored by port 4. • Port 2 & 4 are members in VLAN 3. • Unknown Unicast packet sent to VLAN 3 will egress from port 4 twice, one instance as normal forward and another instance as mirrored from port 2.Port Monitor Commands 415 FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\CLI Folders\Dell Contax CLI\files\Port_Monitor.fm D E L L C O N F I D E N T I A L – P R E L I M I N A RY 9 / 1 2 / 1 2 - F O R P R O O F O N LY • Moreover, if port 2 is an untagged member in VLAN 3 and port 4 is a tagged member then both instances will look different (one tagged and the other is not). • When the port is configured to 802.1X auto mode it will forward any mirrored traffic regardless of the .1X state. However, it will operate as a normal network port (forward traffic) only after authorization is done. • Mirrored traffic is exposed to STP state, i.e. if the port is in STP blocking, it will not egress any mirrored traffic.

Up to 8 TCP ports can be defined in the system, in one command or by using multiple commands. (Range: 1–65536) • address ip-address—Specifies the iSCSI target IP address. If the no form is used and the TCP port to be deleted is one that was bound to a specific IP address, the IP address field must be present. • name targetname—Specifies the iSCSI target name. The name can be statically configured, but it can also be obtained from iSNS or from the sendTargets response. The initiator must present both its iSCSI Initiator Name and the iSCSI Target Name to which it wishes to connect in the first login request of a new session or connection. The name must comprise valid characters, as specified by RFC 3722. (Length: 1–223 characters) Default Configuration iSCSI well-known ports 3260 and 860 are configured as the default target ports, but they can be removed just as any other configured target.iSCSI Commands 591 FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\CLI Folders\Dell Contax CLI\files\iSCSI.fm D E L L C O N F I D E N T I A L – P R E L I M I N A RY 9 / 1 2 / 1 2 - F O R P R O O F O N LY Command Mode Global Configuration mode User Guidelines When working with private iSCSI ports (not IANA assigned iSCSI ports 3260 and 860), it is recommended that the target IP address also be specified, so that the device snoops only frames for which its TCP destination port is one of the configured TCP ports and their destination IP is the target's IP address. In this way, the CPU is not falsely loaded by non-iSCSI flows if other applications choose to use these un-reserved ports. It is the user’s responsibility to not define as iSCSI ports any ports that are well-known or are configured on the product for other uses, such as Telnet, SSH, HTTP, HTTPS, SNMP, or DHCP. To bind a port to an IP address, and the port is already defined but not bound to an IP address, first remove the port by using the no form of the command and then add it again with the relevant IP address. Target names are displayed only when using the show iscsi command. These names are not used to match (or to perform any sanity check on) the iSCSI session information acquired by snooping. A maximum of 16 TCP ports can be configured either bound to IP or not. This number can be changed by using the iscsi max target ports command. However, the change takes effect only after reset. Example The following example configures an iSCSI target port. Console(config)# iscsi target port 30001 address 176.16.1.1 name iqn.1993-11.com.diskvendor:diskarrays.sn.45678.tape:sys1.xyz iscsi cos Use the iscsi cos Global Configuration mode command to set the quality of service profile to apply to iSCSI flows.

Use the Remark option to prioritize iSCSI traffic in the next hop switch, which might be iSCSI-unaware. iSCSI flows are assigned by default with a VPT/DSCP that is mapped to the highest queue not used for stack management or voice VLAN (if the mapping was not changed by the user). The user should also configure the relevant (vpt to queue/dscp to queue) table to complete the setting. Setting the VPT/DSCP sets the QoS profile that determines the egress queue to which the frame is mapped.

The downside of strict priority queuing is that in certain circumstances (heavy high priority traffic), lower priority traffic may become bandwidth-starved. In WRR, the queue to which the flow is assigned can be set to get the required percentage. The user may want to complete the QoS setting by configuring the relevant ports to work in WRR mode with adequate weights. Example The following example sets the QoS profile to apply to iSCSI flows by assigning iSCSI frames with DSCP 31.

If, after recalculation, it is determined that the current session idle time is greater than the new aging time, the session is immediately terminated. Example The following example sets the aging time for iSCSI sessions to 10 minutes.

In the worst case, if all 256 sessions are monitored and are not terminated gracefully, the existing mechanism causes inaccuracies; the last group of monitored iSCSI sessions are aged out after (256/N)*aging-time. In general, the higher the number of ungraceful terminated iSCSI TCP connections, the higher the aging-time inaccuracy.

Command Mode Interface Configuration (Ethernet, VLAN, Port-channel) mode. It cannot be configured for a range of interfaces (range context). User Guidelines Defining a static IP address on an interface implicitly removes the DHCP client configuration on the interface. If the product supports multiple IP addresses: The product supports up to x IP addresses. The IP addresses should be from different IP subnets. When adding an IP address from a subnet that already exists in the list, the new IP address replaces the existing IP address from that subnet. If the product is switch only and supports a single IP address. If the IP address configured in global context then it would be bound to the currently defined management interface. If the management interface is Default VLAN and the VID of the default VLAN is changed then when new setting is applied, the IP address will be automatically redefined on the new Default VLAN. If the IP address is configured in Interface context then the IP address is bound to the interface in context. If a static IP address is already defined, the user must do no IP address in the relevant interface context before changing the IP address. If a dynamic IP address is already defined, the user must do no ip address in the relevant interface context before configuring another dynamic IP address. The Interface context could be a port, LAG or VLAN, depending on support that is defined for the product.

Use the no form of this command to release an acquired IP address. Syntax ip address dhcp no ip address dhcp Parameters No parameters Command Mode Interface Configuration (Ethernet, VLAN, Port-channel) mode. It cannot be configured for a range of interfaces (range context). User Guidelines The ip address dhcp command allows any interface to dynamically learn its IP address by using the DHCP protocol. DHCP client configuration on an interface implicitly removes the static IP address configuration on the interface. If the device is configured to obtain its IP address from a DHCP server, it sends a DHCPDISCOVER message to provide information about itself to the DHCP server on the network. If the ip address dhcp command is used with or without the optional keyword, the DHCP option 12 field (host name option) is included in the DISCOVER message. By default, the host name specified in the option 12 field is the globally configured device host name. The no ip address dhcp command releases any IP address that was acquired, and sends a DHCPRELEASE message.602 IP Addressing Commands FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\CLI Folders\Dell Contax CLI\files\IP_Addressing.fm D E L L C O N F I D E N T I A L – P R E L I M I N A R Y 9 / 1 2 / 1 2 - F O R P R O O F O N LY Example The following example acquires an IP address for gigabitethernet port 1/0/16 from DHCP.

Multiple IPv6 addresses can be configured per interface, but only one link-local address. When the no ipv6 link-local address command is used, the interface is reconfigured with the standard link local address (the same IPv6 link-local address that is set automatically when the enable ipv6 command is used). The system automatically generates a link-local address for an interface when IPv6 processing is enabled on the interface. To manually specify a link-local address to be used by an interface, use the ipv6 link-local address command. The system supports only 64 bits prefix length for link-local addresses. Example console(config)# interface vlan 1 console(config-if)# ipv6 address fe80::123/64 link-local ipv6 unreachables Use the ipv6 unreachables Interface Configuration mode command to enable the generation of Internet Control Message Protocol for IPv6 (ICMPv6) unreachable messages for any packets arriving on a specified interface.

Configuring a new default GW without deleting the previous configured information overwrites the previous configuration. A configured default GW has a higher precedence over automatically advertised (via router advertisement message). Precedence takes effect once the configured default GW is reachable. Reachability state is not verified automatically by the neighbor discovery protocol. Router reachability can be confirmed by either receiving Router Advertisement message containing router's MAC address or manually configured by user using the IPv6 neighbor CLI command. Another option to force reachability confirmation is to ping the router link-local address (this will initiate the neighbor discovery process). If the egress interface is not specified, the default interface is selected. Specifying interface zone=0 is equal to not defining an egress interface.

User Guidelines Duplicate Address Detection (DAD) verifies the uniqueness of new unicast IPv6 addresses before the addresses are assigned to interfaces (the new addresses remain in a tentative state while DAD is performed). DAD uses neighbor solicitation messages to verify the uniqueness of unicast IPv6 addresses. An interface returning to the administrative Up state restarts DAD for all of the unicast IPv6 addresses on the interface. While DAD is performed on the Link Local address of an interface, the state of the other IPv6 addresses is still set to TENTATIVE. When DAD is completed on the Link Local address, DAD is performed on the remaining IPv6 addresses.IPv6 Addressing Commands 635 FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\CLI Folders\Dell Contax CLI\files\IPv6_Addressing.fm D E L L C O N F I D E N T I A L – P R E L I M I N A RY 9 / 1 2 / 1 2 - F O R P R O O F O N LY When DAD identifies a duplicate address, the address state is set to DUPLICATE and the address is not used. If the duplicate address is the Link Local address of the interface, the processing of IPv6 packets is disabled on the interface and an error message is displayed. All configuration commands associated with the duplicate address remain as configured while the address state is set to DUPLICATE. If the Link Local address for an interface changes, DAD is performed on the new Link Local address and all of the other IPv6 address associated with the interface are regenerated (DAD is performed only on the new Link Local address). Configuring a value of 0 with the ipv6 nd dad attempts Interface Configuration mode command disables duplicate address detection processing on the specified interface. A value of 1 configures a single transmission without follow-up transmissions. The default is 1 message. Until the DAD process is completed, an IPv6 address is in the tentative state and cannot be used for data transfer. It is recommended to limit the configured value.

Default Configuration The IPv6 transition-mechanism global support mode is disabled. Command Mode Interface Configuration (Tunnel) mode User Guidelines The system can be enabled to ISATAP tunnel. When enabled, an automatic tunnel interface is created on each interface that is assigned an IPv4 address. Note that on a specific interface (for example, port or VLAN), both native IPV6 and transition-mechanisms can coexist. The host implementation chooses the egress interface according to the scope of the destination IP address (such as ISATAP or native IPv6). Example The following example configures an IPv6 transition mechanism global support mode. Console(config)# interface tunnel 1 Console(config-tunnel)# tunnel mode ipv6ip isatap tunnel isatap router Use the tunnel isatap router Interface Configuration (Tunnel) mode command to configure a global string that represents a specific automatic tunnel router domain name.

Default Configuration The automatic tunnel router's default domain name is ISATAP. Command Mode Interface Configuration (Tunnel) mode User Guidelines The ipv6 tunnel routers-dns command determines the string that the host uses for automatic tunnel router lookup in the IPv4 DNS procedure. By default, the string ISATAP is used for the corresponding automatic tunnel types. Only one string can represent the automatic tunnel router name per tunnel. Using this command, therefore, overwrites the existing entry. Example The following example configures the global string ISATAP2 as the automatic tunnel router domain name. Console(config)# tunnel 1 Console(config-tunnel)# tunnel isatap router ISATAP2 tunnel source Use the tunnel source Interface Configuration (Tunnel) mode command to set the local (source) IPv4 address of a tunnel interface.

If the IPv4 address is changed, then the local address of the tunnel interface is changed too. • ip4-address—Specifies the IPv4 address to use as the source address for packets sent on the tunnel interface. The local address of the tunnel interface is not changed when the IPv4 address is moved to another interface (only if StackTable is changed). Default No source address is defined. Command Mode Interface Configuration (Tunnel) mode User Guidelines The configured source IPv4 address is used for forming the tunnel interface identifier. The interface identifier is set to the 8 least significant bytes of the SIP field of the encapsulated IPv6 tunneled packets. Example console(config)# interface tunnel 1 console(config-tunnel)# tunnel source auto tunnel isatap query-interval Use the tunnel isatap query-interval Global Configuration mode command to set the time interval between Domain Name System (DNS) queries (before the ISATAP router IP address is known) for the automatic tunnel router domain name.

Use the no form of this command to detach a class map from the policy map. Syntax class class-map-name [access-group acl-name] no class class-map-name Parameters • class-map-name—Specifies the name of an existing class map. If the class map does not exist, a new class map is created under the specified name. • acl-name—Specifies the name of an IP or MAC Access Control List (ACL). Default Configuration No class map is defined for the policy map. Command Mode Policy-map Configuration mode User Guidelines Use the policy-map Global Configuration mode command to identify the policy map and to enter the Policy-map Configuration mode before using the class command. After specifying a policy map, a policy for new classes can be configured or a policy for any existing classes in that policy map can be modified. Use the service-policy Interface Configuration (Ethernet, Port-channel) mode command to attach a policy map to an interface. Use an existing class map to attach classification criteria to the specified policy map and use the access-group parameter to modify the classification criteria of the class map. If this command is used to create a new class map, the name of an IP or MAC ACL must also be specified with the access-group parameter.730 Quality of Service (QoS) Commands FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\CLI Folders\Dell Contax CLI\files\QoS.fm D E L L C O N F I D E N T I A L – P R E L I M I N A R Y 9 / 1 2 / 1 2 - F O R P R O O F O N LY Example The following example defines a traffic classification called Class1 with an access-group called Enterprise.

Use the no form of this command to return to the default trust state. Syntax trust cos-dscp no trust Parameters cos-dscp—Specifies that if the packet is IP, then QoS acts as for dscp; otherwise QoS acts as for cos. Default Configuration The default state is untrusted. If the trust command is specified with no parameters, the default mode is dscp. Command Mode Policy-map Class Configuration mode User Guidelines Use this command to distinguish the Quality of Service (QoS) trust behavior for certain traffic from others. For example, incoming traffic with certain DSCP values can be trusted. A class map can be configured to match and trust the DSCP values in the incoming traffic. Trust values set with this command supersede trust values set on specific interfaces with the qos trust Interface Configuration mode command. The trust command and the set Policy-map Class Configuration mode command are mutually exclusive within the same policy map.

Separate values by a space. (Range: 0–255) Default Configuration wrr is disabled by default. The default wrr weight is '1' for all queues. Command Mode Global Configuration mode User Guidelines The ratio for each queue is defined as the queue weight divided by the sum of all queue weights (the normalized weight). This sets the bandwidth allocation of each queue. A weight of 0 indicates that no bandwidth is allocated for the same queue, and the shared bandwidth is divided among the remaining queues. It is not recommended to set the weight of a queue to a 0 as it might stop transmission of control-protocols packets generated by the device. All eight queues participate in the WRR, excluding the expedite queues, in which case the corresponding weight is ignored (not used in the ratio calculation). The expedite queue is a priority queue; it is serviced until empty before the other queues are serviced.

Packets entering a quality of service (QoS) domain are classified at the edge of the QoS domain. When the packets are classified at the edge, the switch port within the QoS domain can be configured to one of the trusted states because there is no need to classify the packets at every switch within the domain. Use this command to specify whether the port is trusted and which fields of the packet to use to classify traffic. When the system is configured with trust DSCP, the traffic is mapped to the queue by the DSCP-queue map. When the system is configured with trust CoS, the traffic is mapped to the queue by the CoS-queue map. Example The following example configures the system to the DSCP trust state. Console(config)# qos trust dscp qos trust (Interface) Use the qos trust Interface Configuration (Ethernet, Port-channel) mode command to enable each port trust state while the system is in the basic QoS mode. Use the no form of this command to disable the trust state on each port. Syntax qos trust no qos trust Default Configuration Each port is enabled while the system is in basic mode.

Use the no form of this command to restore the trusted port with no DSCP mutation. Syntax qos dscp-mutation no qos dscp-mutation Command Mode Global Configuration mode. User Guidelines Apply the DSCP-to-DSCP-mutation map to a port at the boundary of a Quality of Service (QoS) administrative domain. If two QoS domains have different DSCP definitions, use the DSCP-to-DSCP-mutation map to translate a set of DSCP values to match the definition of another domain. Apply the map to ingress and to DSCP-trusted ports only. Applying this map to a port causes IP packets to be rewritten with newly mapped DSCP values at the ingress ports. If applying the DSCP mutation map to an untrusted port, to class of service (CoS), or to an IP-precedence trusted port, the command has no immediate effect until the port becomes DSCP-trusted. Example The following example applies the DSCP Mutation map to system DSCP trusted ports.
