Connecting to the Internet
NOTE: ISPs and ISP offerings vary by country.
To connect to the Internet, you need a modem or network connection and an
Internet service provider (ISP). Your ISP will offer one or more of the
following Internet connection options:
• DSL connections that provide high-speed Internet access through your
existing telephone line or cellular telephone service. With a DSL
connection, you can access the Internet and use your telephone on the
same line simultaneously.
• Cable modem connections that provide high-speed Internet access
through your local cable TV line.
• Satellite modem connections that provide high-speed Internet access
through a satellite television system.
• Dial-up connections that provide Internet access through a telephone line.
Dial-up connections are considerably slower than DSL, cable, and satellite
modem connections.
• Wireless Wide Area Network (WWAN) or Mobile Broadband technology
provides a connection to the Internet using cellular technology at
broadband rates.
• Wireless Local Area Network (WLAN) connections use high-frequency
radio waves to communicate. Typically, a wireless router is connected to
the broadband cable or DSL modem that broadcasts the Internet signal to
your computer.
If you are using a dial-up connection, connect a telephone line to the modem
connector on your computer and to the telephone wall jack before you set up
your Internet connection. If you are using a DSL, cable, or satellite modem
connection, contact your ISP or cellular telephone service for setup
instructions.36 Setting Up Your Computer

NOTE: If you are having problems connecting to the Internet, see "E-Mail, Modem,
and Internet Problems" on page 117. If you cannot connect to the Internet, but have
successfully connected in the past, the ISP may have a service outage. Contact
your ISP to check the service status, or try connecting again later.
NOTE: Have your ISP information ready. If you do not have an ISP, the Connect to
the Internet wizard can help you obtain one.
If you do not have an ISP icon on your desktop or if you want to set up an

Power Protection Devices
Several devices are available to protect against power fluctuations and failures:
• Surge protectors
• Line conditioners
• Uninterruptible power supplies (UPS)
Surge Protectors
Surge protectors and power strips equipped with surge protection help
prevent damage to your computer from voltage spikes that can occur during
electrical storms or after power interruptions. Some surge protector
manufacturers include warranty coverage for certain types of damage.
Carefully read the device warranty when choosing a surge protector. A device
with a higher joule rating offers more protection. Compare joule ratings to
determine the relative effectiveness of different devices.
NOTICE: Most surge protectors do not protect against power fluctuations or
power interruptions caused by nearby lightning strikes. When lightning occurs in
your area, disconnect the telephone line from the telephone wall jack and
disconnect your computer from the electrical outlet.
Many surge protectors have a telephone jack for modem protection. See the
surge protector documentation for modem connection instructions.
NOTICE: Not all surge protectors offer network adapter protection. Disconnect the
network cable from the network wall jack during electrical storms.40 Setting Up Your Computer
Line Conditioners
NOTICE: Line conditioners do not protect against power interruptions.
Line conditioners are designed to maintain AC voltage at a fairly constant level.
Uninterruptible Power Supplies
NOTICE: Loss of power while data is being saved to the hard drive may result in
data loss or file damage.
NOTE: To ensure maximum battery operating time, connect only your computer to
a UPS. Connect other devices, such as a printer, to a separate power strip that
provides surge protection.
A UPS protects against power fluctuations and interruptions. UPS devices
contain a battery that provides temporary power to connected devices when
AC power is interrupted. The battery charges while AC power is available. See
the UPS manufacturer documentation for information on battery operating
time and to ensure that the device is approved by Underwriters Laboratories (UL).Using the Display 41

not supported by your computer and display. Before you change any of the display
settings, make a note of the current settings so you can change back to the
previous settings if you need to.
You can enhance the legibility of text and change the appearance of images
on the screen by adjusting display resolution. As you increase resolution,
items appear smaller on the screen. In contrast, lower resolution causes text 42 Using the Display
and images to appear larger and can benefit people with vision impairments.

Battery Performance
NOTE: For information about the Dell warranty for your computer, see the
Product Information Guide or separate paper warranty document that shipped with
your computer.
For optimal computer performance and to help preserve BIOS settings,
operate your Dell™ portable computer with the main battery installed at all
times. One battery is supplied as standard equipment in the battery bay.
NOTE: Because the battery may not be fully charged, use the AC adapter to
connect your new computer to an electrical outlet the first time you use the
computer. For best results, operate the computer with the AC adapter until the
battery is fully charged. To view battery charge status, place the mouse cursor over
the battery icon in the Windows notification area.
NOTE: Battery operating time (the time the battery can hold a charge) decreases
over time. Depending on how often the battery is used and the conditions under
which it is used, you may need to purchase a new battery during the life of your
computer.
NOTE: It is recommended that you connect your computer to an electrical outlet
when writing to media.
Battery operating time varies depending on operating conditions. Operating
time is significantly reduced when you perform operations including, but not
limited to, the following:
• Using optical drives.
• Using wireless communications devices, ExpressCards, memory cards, or
USB devices.
• Using high-brightness display settings, 3D screen savers, or other powerintensive programs such as complex 3D graphics applications.
• Running the computer in maximum performance mode (see "Power
Management Modes" on page 56 for information about accessing
Windows Power Options Properties or Dell QuickSet, which you can use
to configure power management settings).54 Using a Battery
You can check the battery charge before you insert the battery into the
computer. You can also set power management options to alert you when the
battery charge is low.
CAUTION: Using an incompatible battery may increase the risk of fire or
explosion. Replace the battery only with a compatible battery purchased from
Dell. The battery is designed to work with your Dell computer. Do not use batteries
from other computers with your computer.
CAUTION: Do not dispose of batteries with household waste. When your battery
no longer holds a charge, call your local waste disposal or environmental agency
for advice on disposing of a lithium-ion battery (see "Battery Disposal" in the
Product Information Guide).
CAUTION: Misuse of the battery may increase the risk of fire or chemical burn.
Do not puncture, incinerate, disassemble, or expose the battery to temperatures
above 65°C (149°F). Keep the battery away from children. Handle damaged or
leaking batteries with extreme care. Damaged batteries may leak and cause
personal injury or equipment damage.
Checking the Battery Charge
You can check the battery charge on your computer using any one of the
following methods:
• Dell QuickSet Battery Meter
• Microsoft Windows battery meter icon located in the notification area
• Battery charge/health gauge located on the battery
• Low-battery warning pop-up window
Dell QuickSet Battery Meter
To view the Dell QuickSet Battery Meter:
• Double-click the Dell QuickSet icon in the taskbar, and then click
Battery Meter
or
• Press
The Battery Meter displays the status, battery health, charge level, and charge
completion time for the battery in your computer.
For more information about QuickSet, right-click the QuickSet icon, and
then click Help.Using a Battery 55
Microsoft® Windows® Battery Meter
The battery meter indicates the remaining battery charge. To check the
battery meter, double-click the icon in the notification area.
Charge Gauge
By either pressing once or pressing and holding the status button on the
battery charge gauge, you can check:
• Battery charge (check by pressing and releasing the status button)
• Battery health (check by pressing and holding the status button)
The battery operating time is largely determined by the number of times it is
charged. After hundreds of charge and discharge cycles, batteries lose some
charge capacity—or battery health. Therefore, a battery can show a status of
charged, but maintain a reduced charge capacity (health).
Check the Battery Charge
To check the battery charge, press and release the status button on the battery
charge gauge to illuminate the charge indicator lights. Each light represents
approximately 20 percent of the total battery charge. For example, if the
battery has 80 percent of its charge remaining, four of the lights are on. If no
lights are on, the battery has no charge.
Check the Battery Health
NOTE: You can check battery health in one of two ways: by using the charge gauge
on the battery, as described below, and by using the Battery Meter in Dell QuickSet.
For information about QuickSet, right-click the QuickSet icon in the notification
area, and then click Help.
To check the battery health using the charge gauge, press and hold the status
button on the battery charge gauge for at least 3 seconds to illuminate the
health indicator lights. Each light represents incremental degradation. If no
lights appear, the battery is in good condition, and more than 80 percent of its
original charge capacity remains. If five lights appear, less than 60 percent of the
charge capacity remains, and you should consider replacing the battery (see
"Battery" on page 198 for more information about the battery operating time).56 Using a Battery
Low-Battery Warning
NOTICE: To avoid losing or corrupting data, save your work immediately after a
low-battery warning, then connect the computer to an electrical outlet. If the
battery runs completely out of power, Sleep state begins automatically.
A pop-up window warns you when the battery charge is approximately
90 percent depleted. The computer enters Sleep state when the battery
charge is at a critically low level.
You can change the settings for the battery alarms in Dell QuickSet or the
Power Options window (see "Power Management Modes" on page 56).
Conserving Battery Power
To conserve battery power on your portable computer, do any of the following:

Drivers
What Is a Driver?
A driver is a program that controls a device such as a printer, mouse, or
keyboard. All devices require a driver program.
A driver acts like a translator between the device and any other programs that
use the device. Each device has its own set of specialized commands that only
its driver recognizes.
Dell ships your computer to you with required drivers already installed—no
further installation or configuration is needed.
NOTICE: Your Drivers and Utilities media may contain drivers for operating systems
that are not on your computer. Ensure that you are installing software appropriate
for your operating system.
Many drivers, such as the keyboard driver, come with your Microsoft® Windows®
operating system. You may need to install drivers if you:
• Upgrade your operating system.
• Reinstall your operating system.
• Connect or install a new device.140 Troubleshooting
Identifying Drivers
If you experience a problem with any device, identify whether the driver is the
source of your problem and, if necessary, update the driver.

Using the Operating System Media
Before You Begin
If you are considering reinstalling the Windows operating system to correct a
problem with a newly installed driver, first try using Windows Device Driver
Rollback (see "Using Windows Device Driver Rollback" on page 140).
If Device Driver Rollback does not resolve the problem, then use System
Restore to return your operating system to the operating state it was in before
you installed the new device driver (see "Using MicrosoftWindows System
Restore" on page 145).
NOTICE: Before performing the installation, back up all data files on your primary
hard drive. For conventional hard drive configurations, the primary hard drive is the
first drive detected by the computer.

Using the System Setup Program
NOTE: Your operating system may automatically configure most of the options
available in system setup, thus overriding options that you set through system setup.
An exception is the External Hot Key option, which you can disable or enable only
through system setup. For more information on configuring features for your
operating system, see Windows Help and Support (see "Microsoft Windows XP and
Windows Vista® Help and Support Center" on page 16).
You can use system setup as follows:
• To set or change user-selectable features such as your computer password
• To verify information about the computer's current configuration such as
the amount of system memory
After you set up the computer, run system setup to familiarize yourself with
your system configuration information and optional settings. You may want
to write down the information for future reference.
The system setup screens display the current setup information and settings
for your computer, such as:
• System configuration
• Boot order
• Boot (start-up) configuration
• Basic device configuration settings
• System security and hard drive password settings
NOTE: Unless you are an expert computer user or are directed to do so by Dell
technical support, do not change the system setup settings. Certain changes might
make your computer work incorrectly. 204 Appendix
Viewing the System Setup Screen
1 Turn on (or restart) your computer.
2 When the DELL logo appears, press immediately.
If you wait too long and the Microsoft Windows logo appears, continue to
wait until you see the Windows desktop, then shut down your computer
and try again.
System Setup Screen
NOTE: For information about a specific item on a system setup screen, highlight the
item and see the Help area on the screen.
On each screen, the system setup options are listed at the left. To the right of
each option is the setting or value for that option. You can change settings
that appear as white type on the screen. Options or values that you cannot
change (because they are determined by the computer) appear less bright.
The upper-right corner of the screen displays help information for the
currently highlighted option; the lower-right corner displays information
about the computer. System setup key functions are listed across the bottom
of the screen.
Commonly Used Options
Certain options require that you reboot the computer for new settings to
take effect.
Changing the Boot Sequence
The boot sequence, or boot order, tells the computer where to look to find the
software needed to start the operating system. You can control the boot
sequence and enable/disable devices using the Boot Order page of the system
setup program.
NOTE: To change the boot sequence on a one-time-only basis, see "Performing a
One-Time Boot" on page 205.
The Boot Order page displays a general list of the bootable devices that may
be installed in your computer, including but not limited to the following:
• Diskette Drive
• Internal HDDAppendix 205
• USB Storage Device
• CD/DVD/CD-RW drive
• Modular bay HDD
NOTE: Only devices that are preceded by a number are bootable.
During the boot routine, the computer starts at the top of the list and scans
each enabled device for the operating system start-up files. When the
computer finds the files, it stops searching and starts the operating system.
To control the boot devices, select (highlight) a device by pressing the downarrow or up-arrow key, and then enable or disable the device or change its
order in the list.
• To enable or disable a device, highlight the item and press the space bar.
Enabled items are preceded by a number; disabled items are not preceded
by a number.
• To reorder a device in the list, highlight the device and press to move
the device up the list or to move a device down the list.
Boot sequence changes take effect as soon as you save the changes and exit
the system setup program.
Performing a One-Time Boot
You can set a one-time-only boot sequence without entering the system setup
program (you can also use this procedure to boot the Dell Diagnostics on the
diagnostics utility partition on your hard drive).
1 Shut down the computer through the Start menu.
2 Connect the computer to an electrical outlet.
3 Turn on the computer. When the DELL logo appears, press
immediately.
If you wait too long and the Windows logo appears, continue to wait until
you see the Windows desktop, then shut down your computer and try
again.
4 When the boot device list appears, highlight the device from which you
want to boot and press .
The computer boots to the selected device.
The next time you reboot the computer, the previous boot order is restored.206 Appendix

IP Version 6 (IPv6) Support
The device functions as an IPv6-compliant host, as well as an IPv4 host (also
known as dual stack). 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

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

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

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

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.
For more information on Syslog, see "Logs" on page 195.28 Dell PowerConnect 55xx Systems User Guide

DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY
SNTP
The Simple Network Time Protocol (SNTP) assures accurate network
Ethernet Switch clock time synchronization up to the millisecond. 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.

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.
For more information, see "Password Management" on page 286.Dell PowerConnect 55xx Systems User Guide 31

DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY
Access Control Lists (ACL)
Access Control Lists (ACL) enable network managers to define classification
actions and rules for specific ingress ports. 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.

DHCP Server
Dynamic Host Configuration Protocol (DHCP) provides a means of passing
configuration information (including the IP address of a TFTP server and a
configuration file name) to hosts on a TCP/IP network. 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

Stacking Overview
This section describes how the Stacking feature of the PowerConnect 5500
series functions.
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

Stack Topology
The PowerConnect 5500 series systems operates in a ring or chain topology.
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

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:

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. The dynamic Dell PowerConnect 55xx Systems User Guide 53

DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY
configuration is not saved, for example, dynamically-learned MAC addresses
are not saved, but dynamic information is learned quickly and automatically
by network traffic.
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. Port Configurations when Replacing Units

DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY
Loading Software onto Stack Members
Software can be downloaded to all units simultaneously, or to the master unit
alone. 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

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 5-1) using an 8-pin RJ-45 male connector.
Figure 5-1. 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).

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 5-2:
• Power
• Status
• Fan (should be green)
• RPS (if it is being used)

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 "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).
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

Using the CLI
This section provides some general information for using the CLI.
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. Dell PowerConnect 55xx Systems User Guide 69
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
Privileged access can be protected, to prevent unauthorized access and to
secure operating parameters. 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. Global Configuration commands apply to system features, rather than a
specific protocol or interface.

To access Global Configuration mode, at the Privileged EXEC Mode prompt,
type configure and press . 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

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

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.

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.

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.
The device is now configured with an IP address.

Security Management and Password
Configuration
System security is handled through the Authentication, Authorization, and
Accounting (AAA) mechanism that manages user access rights, privileges,
and management methods. 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

Software Download
This section contains instructions for downloading device software (system
and boot images) through a TFTP server or USB port. 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.
To download the system image from a TFTP server, ensure that an IP address
is configured on one of the device ports and pings can be sent to the TFTP
server. In addition, ensure that the file to be downloaded is saved on the
TFTP server.
To download a system image through the USB port or TFTP server:
1 Enter the show version command, to verify which software version is
currently running on the device. The following is an example of the
information that appears:

Port Security
Network security can be enhanced by limiting access on a port to users with
specific MAC addresses. 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. Dell PowerConnect 55xx Systems User Guide 99

dynamic MAC addresses associated with the port. The port learns
up to the maximum addresses allowed on the port. Both
relearning and aging MAC addresses are enabled.
– Max Entries (0-128) — Enter the maximum number of MAC
addresses that can be learned on the port. The Max Entries field is

• Shutdown — Discard the packet from any unlearned source, and
shut down the port. Ports remain shutdown until they are
reactivated, or the device is reset.

ACLs
This section describes Access Control Lists (ACLs), which enable defining
classification actions and rules for specific ingress or egress ports.
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.
The following types of ACLs can be defined:
• MAC-based ACL — Examines Layer 2 fields only
• IPv4-based ACL —Examines the Layer 3 layer of IPv4 frames104 Dell PowerConnect 55xx Systems User Guide

ACL Binding
When an ACL is bound to an interface, all the rules that have been defined
for the ACL are applied to that interface. Whenever an ACL is assigned on a
port or LAG, flows from that ingress or egress interface that do not match the
ACL, are matched to the default rule, which is to Drop unmatched packets.
To change the default action for unmatched packets to an action other than
Drop, do the following:
• Add an additional ACE to the ACL with "Any" in all fields
• Set its action other than Drop
• Set the priority to the lowest in the ACL.

If a time range includes both absolute and recurring ranges, the ACL is
activated only if both absolute start time and the recurring time range have
been reached. The ACL is deactivated when either of the time ranges is
reached.
The switch supports a maximum of 10 absolute time ranges.
All time specifications are interpreted as local time (Daylight Savings Time
does not affect this).
To ensure that the time range entries take effect at the desired times, the

Dot1x Authentication
This section describes Dot1x authentication.
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

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

The possible options are:
• 802.1x Only — 802.1X authentication is the only authentication
method performed on the port.
• MAC Only — Port is authenticated, based on the supplicant
MAC address. Only eight MAC-based authentications can be
used on the port.
• 802.1x & MAC — Both 802.1X and MAC-based authentication
are performed on the switch. The 802.1X authentication takes
precedence.
NOTE: For MAC authentication to succeed, the RADIUS server supplicant
username and password must be the supplicant MAC address. The MAC
address must be in lower case letters and entered without the “:” or “-”
separators; for example: 0020aa00bbcc.
– Dynamic VLAN Assignment — Enable/disable dynamic VLAN
assignment for this port. This feature enables you to automatically
assign users to VLANs during the RADIUS server authentication.
When a user is authenticated by the RADIUS server, the user is
automatically joined to the VLAN configured on a RADIUS server.
• Port Lock and Port Monitor should be disabled when DVA is
enabled.
• Dynamic VLAN Assignment (DVA) can occur only if a RADIUS
server is configured, and port authentication is enabled and set to
802.1x multi-session mode.
• If the RADIUS Accept Message does not contain the supplicant’s
VLAN, the supplicant is rejected.142 Dell PowerConnect 55xx Systems User Guide

The following is an example of the CLI commands:
Power over Ethernet
A Power over Ethernet (PoE) switch is a type of PSE (Power Sourcing
Equipment) that delivers electrical power to connected Powered Devices
(PDs) over existing copper cables, without interfering with the network
traffic, updating the physical network or modifying the network
infrastructure.
Using PoE eliminates the need to:
• Place all network devices next to power sources.
• Deploy double-cabling systems, significantly decreasing installation costs.
PoE can be used in any network that deploys relatively low-powered devices
connected to the Ethernet LAN. PDs are devices that receive power from the
PowerConnect power supplies, such as:
• IP phones

SNTP Overview
The switch supports the Simple Network Time Protocol (SNTP), which
provides accurate network switch clock time synchronization of up to 100
milliseconds. 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

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). Dell PowerConnect 55xx Systems User Guide 181
FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell
Contax\sources\CxUGSystemConfig.fm
DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY
MD5 (Message Digest 5) Authentication safeguards device synchronization
paths to SNTP servers. 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.
Global Settings (Clock Source)
System time can be set manually, or it may be received from an external
SNTP server. You if wish to set the system time manually, you do not to use
the Global Settings page, because the default is manual (local) system time.
To set the clock source:
1 Click System > Time Synchronization > Global Settings in the tree view

Logs
The Logs feature enables the switch to keep several, independent logs. 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. Dell PowerConnect 55xx Systems User Guide 197

IP Addressing
This section describes how to configure IP addresses on the switch, and
contains the following topics:
• IP Addressing Overview
• IPv4 Interface Parameters
• DHCP IPv4 Interface
• IPv4 Static Routing
• IPv6 Interfaces
• IPv6 Default Gateway
• ISATAP Tunnel
• IPv6 Neighbors
• IPv6 Routes Table
• Domain Name System
• Default Domain Names
• Host Name Mapping
• ARP
• UDP Relay
IP Addressing Overview
The device functions as an IPv6-compliant host, as well as an IPv4-host (also
known as dual stack). 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.
In addition to the above validation procedure every time a switch receives an
ARP request with a sender IP address that is equal to its IP address defined on
the input interface it sends a SYSLOG message informing of IP duplication,
containing the sender IP and MAC addresses, from the received ARP
message.
To assign an IP address to an interface, and to define subnets to which traffic

DHCP IPv4 Interface
The switch can operate in the following ways:
• It can function as a DHCP client that obtains its own IP from a DHCP
server, as described in this section
• It can function as a DHCP server that allocates IP addresses to other
devices, as described in "DHCP Server" on page 297
When the interface is configured as a DHCP client, it keeps requesting an IP
address from the DHCP server, until it receives one. 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

2 Select an interface. The IPv6 addresses defined on the interface are
displayed. In addition to the fields described in the Add pages, the
following fields are displayed:
– ICMP Error Rate Limit Interval (0-2147483647) — Enter the
rate-limit interval for ICMPv6 error messages in milliseconds. The
value of this parameter together with the Bucket Size parameter
(below) determines how many ICMP error messages may be sent per
time interval, for example, a rate-limit interval of 100 ms and a bucket
size of 10 messages translates to 100 ICMP error messages per second.
– ICMP Error Rate Limit Bucket Size (1-200) — Enter the bucket size
for ICMPv6 error messages. The value of this parameter together with
the ICMP Error Rate Limit Interval parameter determines how many
ICMP error messages may be sent per time interval, for example, a
rate-limit interval of 100 ms and a bucket size of 10 messages
translates to 100 ICMP error messages per second.
3 To add a new IPv6 interface, click Add IPv6 Interface, and enter the fields:
– Interface — Select an IPv6 interface to be configured.
– Number of DAD Attempts — Enter the number of consecutive
neighbor solicitation messages that are sent on an interface while
Duplicate Address Detection (DAD) is performed on Unicast IPv6
addresses on this interface. New addresses remain in a tentative state
while duplicate address detection is performed. A field value of 0,
disables duplicate address detection processing on the specified
interface. A field value of 1, indicates a single transmission without
follow up transmissions.
– Autoconfiguration — Enable/disable stateless auto configuration of
IPv6 address assignment. When enabled, the router solicitation ND
procedure is initiated. This discovers a router in order to assign an IP
address to the interface, based on prefixes received with RA messages.
When auto configuration is disabled, no automatic assignment of
IPv6 global Unicast addresses is performed, and existing,
automatically-assigned IPv6 global Unicast addresses are removed
from the interface. Dell PowerConnect 55xx Systems User Guide 223

– Send ICMP Unreachable — Enable/disable transmission of ICMPv6
address Unreachable messages. When enabled, unreachable messages
are generated for any packet arriving on the interface with unassigned
TCP/UDP port.
4 To add an address to an IPv6 interface, click Add IPv6 Address, and enter
the fields for the selected interface:
– IPv6 Address Type — Check the means by which the IP address was
added to the interface. The possible options are:
• Link Local — The IP address is link local; non-routable and can
be used for communication on the same network only. A Link
Local address has a prefix of 'FE80'.
• Global Unicast — The IP address is a globally unique IPv6
Unicast address; visible and reachable from different subnets.
• Global Anycast — The IP address is a globally unique IPv6
Anycast address; visible and reachable from different subnets.
– IPv6 Address — Enter the IPv6 address assigned to the interface. The
address must be a valid IPv6 address, specified in hexadecimal using
16-bit values between colons. An example of an IPv6 address is
2031:0:130F:0:0:9C0:876A:130D and the compressed version is
represented as 2031:0:130F::9C0:876A:130D. Up to five IPv6
addresses (not including Link Local addresses) can be set per
interface, with the limitation of up to128 addresses per system.
– Prefix Length — For global Unicast or Anycast, enter the length of the
IPv6 prefix. The length is a decimal value that indicates how many of
the high-order contiguous bits of the address comprise the prefix (the
network portion of the address). The Prefix field is applicable only on a
static IPv6 address defined as a Global IPv6 address.
– EUI-64 — For global Unicast or Anycast, check to use the EUI-64
option.224 Dell PowerConnect 55xx Systems User Guide

Use the IPv6 Default Gateway pages to configure and view the default IPv6
router addresses. This list contains routers that are candidates to become the
switch default router for non-local traffic. The switch randomly selects a
router from the list. The switch supports one static IPv6 default router.
Dynamic default routers are routers that have sent router advertisements to

When adding or deleting IP addresses, the following events occur:
• When removing an IP interface, all of its default gateway IP addresses are
removed.
• Dynamic IP addresses cannot be removed.
• An alert message is displayed after a user attempts to insert more than one

The following are examples of these CLI command:
ISATAP Tunnel
To deliver IPv6 addresses in an IPv4 network, a tunneling process must be
defined that encapsulates IPv6 packets in IPv4 packets.
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. Thus, a Link Local address will be represented as FE80::5EFE:w.x.y.z

After the last IPv4 address is removed from the interface, the ISATAP IP
interface state becomes inactive and is represented as Down, however the
Admin state remains Enabled.
When defining tunneling, note the following:
• An IPv6 Link Local address is assigned to the ISATAP interface. The initial
IP address is assigned to the interface, and the interface state becomes
Active.
• If an ISATAP interface is active, the ISATAP router IPv4 address is resolved
via DNS by using ISATAP-to-IPv4 mapping. If the ISATAP DNS record is
not resolved, the ISATAP host name-to-address mapping is searched in the
host name cache.
• When an ISATAP router IPv4 address is not resolved via the DNS process,
the status of the ISATAP IP interface remains Active. The system does not
have a default gateway for ISATAP traffic until the DNS procedure is
resolved.
• In order for an ISATAP Tunnel to work properly over an IPv4 network, an
ISATAP router is must be set up.Dell PowerConnect 55xx Systems User Guide 231

Domain Name System
The 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 and their corresponding IP addresses.
To add a DNS server and specify the active DNS server:
1 Click System > IP Addressing > Domain Name System in the tree view
to display the Domain Name System: Summary page.
Figure 9-24. Domain Name System: Summary
The list of previously-defined DNS servers is displayed.
2 To enable mapping of host names into IP addresses through a DNS server,
select DNS Status.
3 To activate one of the currently-defined DNS servers, enable Active Server.Dell PowerConnect 55xx Systems User Guide 243

4 To add a DNS server, click Add, and enter the fields:
– Supported IP Format — Select whether the IPv4 or IPv6 format is
supported.
– IPv6 Address Type — When the server supports IPv6, this specifies
the type of static address supported. The possible options are:
• Link Local — A Link Local address that is non-routable and used
for communication on the same network only.
• Global — A globally unique IPv6 address; visible and reachable
from different subnets.
– Link Local Interface — When the server supports an IPv6 Link Local
address, this specifies the Link Local interface. The possible options
are:
• VLAN — The VLAN on which the IPv6 interface is configured.
• ISATAP — The IPv6 interface is configured on an ISATAP
tunnel.
– DNS Server — Enter the IP address of the DNS server being added.
– DNS Server Currently Active — Displays the DNS server that is
currently active.
– Set DNS Server Active — Check to activate the selected DNS server.
Configuring DNS Servers Using the CLI Commands
The following table summarizes the CLI commands for configuring the fields
in the Domain Name System pages.
Table 9-33. DNS CLI Commands
CLI Command Description
ip domain lookup Enables DNS system for translating host
names to IP addresses.
ip name-server {server1-
ipv4-address|server1-ipv6-
address} [server-address2
…server-address8]
no ip name-server [serveraddress … server-address8]
Sets the available name servers. Up to eight
name servers can be set.
The no form of the command removes a
name server.244 Dell PowerConnect 55xx Systems User Guide

Default Domain Names
A default domain name is used when an IP address cannot be mapped to a
known domain name. This domain name is applied to all unqualified host
names.
To define the default domain name:
1 Click System > IP Addressing > Default Domain Name to display the
Default Domain Name page.
Figure 9-25. Default Domain Name
If there is a currently-defined default domain name, it is displayed.
2 Enter the Default Domain Name (1 - 160 Characters).
Its Type is displayed, and has one of the following options:
– Dynamic — The IP address was created dynamically.
– Static — The IP address is a static IP address.246 Dell PowerConnect 55xx Systems User Guide
