About this Guide
This guide describes the protocols and features supported on Dell Networking switches and routers by
the Dell Networking operating system (OS) and provides configuration instructions and examples for
implementing them.
The S5000 switch is available with Dell Networking OS version 9.1(1.0) and later version. It also supports
stacking.
Though this guide contains information on protocols, it is not intended to be a complete reference. This
guide is a reference for configuring protocols on Dell Networking systems. For complete information
about protocols, refer to other documentation including IETF Requests for Comment (RFCs). The
instructions in this guide cite relevant RFCs, and the Standards Compliance chapter contains a complete
list of the supported RFCs and Management Information Base files (MIBs).
Audience
This document is intended for system administrators who are responsible for configuring and maintaining
networks and assumes that you are knowledgeable in Layer 2 and Layer 3 networking technologies.
Conventions
This guide uses the following conventions to describe command syntax.

Configuration Fundamentals
The Dell Networking OS command line interface (CLI) is a text-based interface that you use to configure
interfaces and protocols.
The CLI is structured in modes for security and management purposes. Different sets of commands are
available in each mode, and you can limit user access to modes using privilege levels.
In Dell Networking OS, after you enable a command, it is entered into the running configuration file. You
can view the current configuration for the whole system or for a particular CLI mode. To save the current
configuration, copy the running configuration to another location. For more information, refer to Saving
the Running-Configuration.
Accessing the Command Line
Access the command line through a serial console port or a Telnet session as shown in the following
example.
When the system successfully boots, you enter the command line in EXEC mode (shown in bold).
NOTE: You must have a password configured on a virtual terminal line before you can Telnet into
the system. Therefore, you must use a console connection when connecting to the system for the
first time.

CLI Modes
Different sets of commands are available in each mode.
A command found in one mode cannot be executed from another mode (except for EXEC mode
commands preceded by the do command; for more information, refer to The do Command and EXEC
Privilege Mode commands).
You can set user access rights to commands and command modes using privilege levels; for more
information about privilege levels and security options, refer to Privilege Levels Overview.
The Dell Networking OS CLI is divided into three major mode levels:
38
Configuration Fundamentals
• EXEC mode — is the default mode and has a privilege level of 1, which is the most restricted level.
Only a limited selection of commands is available, notably the show commands, which allow you to
view system information.
• EXEC Privilege mode — has commands to view configurations, clear counters, manage configuration
files, run diagnostics, and enable or disable debug operations. The privilege level is 15, which is
unrestricted. You can configure a password for this mode; for more information, refer to Configuring
the Enable Password.
• CONFIGURATION mode — allows you to configure security features, time settings, set logging and
simple network management protocol (SNMP) functions, and static address resolution protocol (ARP)
and MAC addresses on the system.
Beneath CONFIGURATION mode are sub-modes that apply to interfaces, protocols, and features. The
following example shows this sub-mode command structure. When configuring the chassis for the first
time, two sub-CONFIGURATION modes are important:
• INTERFACE sub-mode — is the mode in which you configure Layer 2 and Layer 3 protocols and IP
services specific to an interface. An interface can be physical (management interface, 10-Gigabit
Ethernet, 40-Gigabit Ethernet, or 2/4/8-Gigabit Universal Port) or logical (Loopback, Null, port
channel, or virtual local area network [VLAN]).
• LINE sub-mode — is the mode in which you to configure the console and virtual terminal lines.
NOTE: At any time, entering a question mark (?) displays the available command options. For
example, when you are in CONFIGURATION mode, entering the question mark first lists all the
available commands, including the possible sub-modes.

Navigating CLI Modes
The Dell Networking OS prompt changes to indicate the CLI mode.
The following table lists the CLI mode, its prompt, and information about how to access and exit the CLI
mode. Move linearly through the command modes, except for the end command which takes you
directly to EXEC Privilege mode and the exit command which moves you up one command mode level.
NOTE: Sub-CONFIGURATION modes all have the letters “conf” in the prompt with more modifiers
to identify the mode and slot/port information.

Port Numbering Convention
The S5000 switch uses following port numbering convention.
Odd-numbered ports are at the top and even-numbered ports are at the bottom of the I/O panel.
The following shows the fixed four 40GbE data ports and the four slots for pluggable modules on the
S5000 I/O panel. You can also use the 40GbE ports in 4 × 10GbE mode.
Figure 1. Port Numbering Convention
The S5000 supports the following possible modules:
• Twelve-Port Ethernet module (1G/10G speeds)
• Twelve-Port Universal Port module (2G/4G/8G/10G speeds)
You can install an Ethernet module in any slot (from 0 to 3) and a Universal Port module in slot 0 on the
I/O panel.
On the S5000, the valid stack-unit numbers are from 0 to 11. The valid port numbers for each interface
type are:
• 1GbE: Ports from 0 to 47
• 10GbE: Ports from 0 to 63
• 40GbE: Ports 48, 52, 56, and 60
• Universal Port: Ports from 0 to 47
• Management: Port 0
• Fibre Channel: Ports from 0 to 11
The do Command
You can enter an EXEC mode command from any CONFIGURATION mode (CONFIGURATION,
INTERFACE, SPANNING TREE, and so on.) without having to return to EXEC mode by preceding the EXEC
mode command with the do command.
The following example shows the output of the do command.
Dell(conf)#do show system brief

The no Command
When you enter a command, the command line is added to the running configuration file. Disable a
command and remove it from the running-config by entering the original command preceded by the no
command.
For example, to delete an ip address configured on an interface, use the no ip address ip-address
command, as shown in bold in the following example.
NOTE: To help you construct the “no” form of a command, use the help or ? command as
described in Obtaining Help.

Obtaining Help
Obtain a list of keywords and a brief functional description of those keywords at any CLI mode using
the ? or help command:
• To list the keywords available in the current mode, enter ? at the prompt or after a keyword.
• Enter ? after a prompt lists all of the available keywords. The output of this command is the same for
the help command.
• Enter ? after a partial keyword lists all of the keywords that begin with the specified letters.
• Enter [space]? after a keyword lists all of the keywords that can follow the specified keyword.
? Command Example
Dell#?
start Start Shell
capture Capture Packet
cd Change current directory
clear Reset functions
clock Manage the system clock
configure Configuring from terminal
copy Copy from one file to another
--More--
Keyword? Command Example
? after a partial keyword lists all of the keywords that begin with the specified letters.
Dell(conf)#cl?
class-map
clock
Dell(conf)#cl
Keyword ? Command Example
A keyword followed by [space]? lists all of the keywords that can follow the specified keyword.
Dell(conf)#clock ?
summer-time Configure summer (daylight savings) time
timezone Configure time zone
Dell(conf)#clock
Entering and Editing Commands
Notes for entering commands.
• The CLI is not case-sensitive.
• You can enter partial CLI keywords.
– Enter the minimum number of letters to uniquely identify a command. For example, you cannot
enter cl as a partial keyword because both the clock and class-map commands begin with the
letters “cl.” You can enter clo, however, as a partial keyword because only one command begins
with those three letters.
• The TAB key autocompletes keywords in commands. Enter the minimum number of letters to
uniquely identify a command.
• The UP and DOWN arrow keys display previously entered commands (refer to Command History).
• The BACKSPACE and DELETE keys erase the previous letter.
44
Configuration Fundamentals
• Key combinations are available to move quickly across the command line. The following table
describes these short-cut key combinations.
Short-Cut Key
Combination
CNTL-A Moves the cursor to the beginning of the command line.
CNTL-B Moves the cursor back one character.
CNTL-D Deletes character at cursor.
CNTL-E Moves the cursor to the end of the line.
CNTL-F Moves the cursor forward one character.
CNTL-I Completes a keyword.
CNTL-K Deletes all characters from the cursor to the end of the command line.
CNTL-L Re-enters the previous command.
CNTL-N Return to more recent commands in the history buffer after recalling commands
CNTL-P Recalls commands, beginning with the last command.
CNTL-R Re-enters the previous command.
CNTL-U Deletes the line.
CNTL-W Deletes the previous word.
Action
with CTRL-P or the UP arrow key.
CNTL-X Deletes the line.
CNTL-Z Ends continuous scrolling of command outputs.
Esc B Moves the cursor back one word.
Esc F Moves the cursor forward one word.
Esc D Deletes all characters from the cursor to the end of the word.
Command History
Dell Networking OS maintains a history of previously entered commands for each mode.
For example:
• When you are in EXEC mode, the UP and DOWN arrow keys display the previously entered EXEC
mode commands.
• When you are in CONFIGURATION mode, the UP or DOWN arrows keys recall the previously entered
CONFIGURATION mode commands.
Filtering show Command Outputs
Filter the output of a show command to display specific information by adding | [except | find |
grep | no-more | save]
The variable specified_text is the text for which you are filtering and it IS case sensitive unless you
use the
ignore-case sub-option.
specified_text after the command.
Configuration Fundamentals
45
The grep command accepts an ignore-case sub-option that forces the search to case-insensitive. For
example, the commands:
• show run | grep Ethernet returns a search result with instances containing a capitalized
“Ethernet,” such as interface TenGigabitEthernet 0/0.
• show run | grep ethernet would not return that search result because it only searches for
instances containing a non-capitalized “ethernet.”
• show run | grep Ethernet ignore-case returns instances containing both “Ethernet” and
“ethernet.”
The grep command displays only the lines containing specified text. The following example shows this
command used in combination with the do show stack-unit all stack-ports all pfc
details | grep 0 command.
Dell(conf)#do show stack-unit all stack-ports all pfc details | grep 0
stack unit 0 stack-port all
0 Pause Tx pkts, 0 Pause Rx pkts
0 Pause Tx pkts, 0 Pause Rx pkts
0 Pause Tx pkts, 0 Pause Rx pkts
0 Pause Tx pkts, 0 Pause Rx pkts
0 Pause Tx pkts, 0 Pause Rx pkts
0 Pause Tx pkts, 0 Pause Rx pkts
NOTE: Dell Networking OS accepts a space or no space before and after the pipe. To filter a phrase
with spaces, underscores, or ranges, enclose the phrase with double quotation marks.
The except keyword displays text that does not match the specified text. The following example shows
this command used in combination with the do show stack-unit all stack-ports all pfc
details | except 0 command.

The find keyword displays the output of the show command beginning from the first occurrence of
specified text. The following example shows this command used in combination with the do show
stack-unit all stack-ports all pfc details | find 0
command.
Filtering Command Outputs with the find Command
Dell(conf)#do show stack-unit all stack-ports all pfc details | find 0

Configuration Fundamentals
The display command displays additional configuration information.
The no-more command displays the output all at once rather than one screen at a time. This is similar to
terminal length command except that the no-more option affects the output of the specified
the
command only.
The save command copies the output to a file for future reference.
NOTE: You can filter a single command output multiple times. The save option must be the last
option entered. For example: Dell# command | grep regular-expression | except
regular-expression | grep other-regular-expression | find regular-expression
| save.
Multiple Users in Configuration Mode
Dell Networking OS notifies all users when there are multiple users logged in to CONFIGURATION mode.
A warning message indicates the username, type of connection (console or VTY), and in the case of a VTY
connection, the IP address of the terminal on which the connection was established. For example:
• On the system that telnets into the switch, this message appears:
% Warning: The following users are currently configuring the system:
User "<username>" on line console0
• On the system that is connected over the console, this message appears:
% Warning: User "<username>" on line vty0 "10.11.130.2" is in configuration
mode
If either of these messages appears, Dell Networking recommends coordinating with the users listed in
the message so that you do not unintentionally overwrite each other’s configuration changes.

Getting Started
This chapter helps you get started using the S5000.
Accessing Ports
The S5000 has two management ports available for system access — a console port and a universal serial
bus (USB)-B port.
The USB-B port acts the same as the console port. The terminal settings are the same for both access
ports.
Accessing the RJ-45/RS-232 Console Port
The RS-232/RJ-45 console port is labeled on the lower left-hand side of the S5000 system as you face
the Utility side of the chassis.
NOTE: Before starting this procedure, be sure that you have a terminal emulation program already
installed on your PC.
Figure 2. RS-232/RJ-45 Console Port
To access the console port, follow these steps.
1. Install an RJ-45 copper cable into the console port. Use a rollover (crossover) cable to connect the
S5000 console port to a terminal server.
2. Connect the other end of the cable to the DTE terminal server.
3. Terminal settings on the console port cannot be changed in the software and are set as follows:
• 9600 baud rate
• No parity
• 8 data bits
• 1 stop bit
48
Getting Started
• No flow control
Pin Assignments
You can connect to the console using a RJ-45 to RJ-45 rollover cable and a RJ-45 to DB-9 female DTE
adapter to a terminal server (for example, a PC).
The pin assignments between the console and a DTE terminal server are as follows:

Device
Accessing the CLI Interface and Running Scripts Using SSH
In addition to the capability to access a device using a console connection or a Telnet session, you can
also use SSH for secure, protected communication with the device. You can open an SSH session and run
commands or script files. This method of connectivity is supported with S4810, S4048–ON, S3048–ON,
S4820T, and Z9000 switches and provides a reliable, safe communication mechanism.
Entering CLI commands Using an SSH Connection
You can run CLI commands by entering any one of the following syntax to connect to a switch using the
preconfigured user credentials using SSH:
ssh username@hostname <CLI Command>
or
echo <CLI Command> | ssh admin@hostname
The SSH server transmits the terminal commands to the CLI shell and the results are displayed on the
screen non-interactively.
Executing Local CLI Scripts Using an SSH Connection
You can execute CLI commands by entering a CLI script in one of the following ways:
Getting Started
49
ssh username@hostname <CLIscript.file>
or
cat < CLIscript.file > | ssh admin@hostname
The script is run and the actions contained in the script are performed.
Following are the points to remember, when you are trying to establish an SSH session to the device to
run commands or script files:
• There is an upper limit of 10 concurrent sessions in SSH. Therefore, you might expect a failure in
executing SSH-related scripts.
• To avoid denial of service (DoS) attacks, a rate-limit of 10 concurrent sessions per minute in SSH is
devised. Therefore, you might experience a failure in executing SSH-related scripts when multiple
short SSH commands are executed.
• If you issue an interactive command in the SSH session, the behavior may not really be interactive.
• In some cases, when you use an SSH session, when certain show commands such as show tech-
support
truncated and not displayed. This may cause one of the commands to fail for syntax error. In such
cases, if you add few newline characters before the failed command, the output displays completely.
Execution of commands on CLI over SSH does not notice the errors that have occurred while executing
the command. As a result, you cannot identify, whether a command has failed to be processed. The
console output though is redirected back over SSH.
produce large volumes of output, sometimes few characters from the output display are
Default Configuration
A version of Dell Networking OS is pre-loaded onto the chassis; however, the system is not configured
when you power up for the first time (except for the default hostname, which is Dell). You must
configure the system using the CLI.
Accessing the USB-B Console Port
When you connect the USB-B port, it becomes the primary connection and, when the system is
connected, it sends all messages to the USB-B drive.
The terminal settings are the same for the USB-B port and the console port.
1. Power on the PC (Dell Networking recommends using the XP operating system).
2. Connect the USB-A end of cable into an available USB port on the PC.
3. Connect the USB-B end of cable into the USB-B console port on the S5000.
4. Power on the S5000.
5. Install the necessary USB device drivers (you need an internet connection). For assistance, contact
Dell Networking Technical Support.
6. Open your terminal software emulation program to access the S5000.
7. Set the terminal connection settings.
• 9600 baud rate
• No parity
• 8 data bits
• 1 stop bit
50
Getting Started
• No flow control
The command line interface (CLI) prompt appears (Dell>_) when you are connected to the S5000.
NOTE: Only one of the console ports can be active at a time; by default, the USB console takes
priority over the RJ-45 console. When a USB host (PC) is plugged into the USB console port, the
hardware automatically switches over to use the USB console. When the USB cable is removed or
the PC deactivates the USB connection, the hardware automatically switches to the RJ-45 console
interface.
Booting Process
After you set up the S5000 as described in the installation procedure in the S5000 Getting Started Guide,
the switch boots up.
The following example shows an example of the completed boot process.

Enter the Initial Configuration Information
To set up the switch, assign an IP address and other configuration information necessary for the switch to
communicate with the local routers and the Internet.
The minimal configuration provided here does not cover most of the features; it simply allows you to
perform other configuration tasks using a Telnet connection from your management network.
You need this information from your network administrator:
• Switch IP address
• Subnet mask (IP netmask)
• Default gateway (router)
• Enable secret password
• Enable password
• Telnet password
Configuring the Enable Password
Access EXEC Privilege mode using the enable command. EXEC Privilege mode is unrestricted by default.
Configure a password as a basic security measure.
There are two types of enable passwords:
• enable password stores the password in the running/startup configuration using a DES encryption
method.
• enable secret is stored in the running/startup configuration in using a stronger, MD5 encryption
method.
Dell Networking recommends using the enable secret password.
To configure an enable password, use the following command.
• Create a password to access EXEC Privilege mode.
CONFIGURATION mode
enable [password | secret] [level level] [encryption-type] password
– level: is the privilege level, is 15 by default, and is not required.
Getting Started
53
– encryption-type: specifies how you are inputting the password, is 0 by default, and is not
required.
* 0 is for inputting the password in clear text.
* 7 is for inputting a password that is already encrypted using a DES hash. Obtain the encrypted
password from the configuration file of another S5000 switch.
* 5 is for inputting a password that is already encrypted using an MD5 hash. Obtain the
encrypted password from the configuration file of another S5000 switch.
Configuring a Host Name
The host name appears in the prompt. The default host name is Dell.
• Host names must start with a letter and end with a letter or digit.
• Characters within the string can be letters, digits, and hyphens.
To create a host name, use the following command.
• Create a host name.
CONFIGURATION mode
hostname name
Example of the hostname Command
Dell(conf)#hostname R1
R1(conf)#
Navigating CLI Modes
The Dell prompt changes to indicate the CLI mode.
You must move linearly through the command modes, except for the end command which takes you
directly to EXEC Privilege mode and the exit command which moves you up one command mode level.
Default Configuration
A version of Dell Networking OS is pre-loaded onto the chassis; however, the system is not configured
when you power up for the first time (except for the default hostname, which is Dell). You must
configure the system using the CLI.
Configuring Layer 2 (Data Link) Mode
To enable Layer 2 data transmissions through an individual interface, use the switchport command in
INTERFACE mode
You cannot configure switching or Layer 2 protocols such as spanning tree protocol (STP) on an interface
unless the interface is set to Layer 2 mode.
1. Enable the interface.
INTERFACE mode
no shutdown
2. Place the interface in Layer 2 (switching) mode.
54
Getting Started
INTERFACE mode
switchport
To view the interfaces in Layer 2 mode, use the show interfaces switchport command in EXEC
mode.
Accessing the System Remotely
You can configure the system to access it remotely by Telnet or SSH. The system has a dedicated
management port and a management routing table that is separate from the IP routing table.
Configuring the system for Telnet is a three-step process:
1. Configure an IP address for the management port. Configure the Management Port IP Address
2. Configure a management route with a default gateway. Configure a Management Route
3. Configure a username and password. Configuring a Username and Password
Configure the Management Port IP Address
To access the system remotely, assign IP addresses to the management ports.
NOTE: Assign different IP addresses to each stack-unit’s management port.
1. Enter INTERFACE mode for the Management port.
CONFIGURATION mode
interface ManagementEthernet slot/port
• slot: the range is from 0 to 11.
• port: the range is 0.
2. Assign an IP address to the interface.
INTERFACE mode
ip address ip-address/mask
• ip-address: an address in dotted-decimal format (A.B.C.D).
• mask: a subnet mask in /prefix-length format (/ xx).
3. Enable the interface.
INTERFACE mode
no shutdown
Configure a Management Route
Define a path from the system to the network from which you are accessing the system remotely.
Management routes are separate from IP routes and are only used to manage the system through the
management port.
To configure a management route, use the following command.
• Configure a management route to the network from which you are accessing the system.
CONFIGURATION mode
Getting Started
55
management route ip-address/mask gateway
– ip-address: the network address in dotted-decimal format (A.B.C.D).
– mask: a subnet mask in /prefix-length format (/ xx).
– gateway: the next hop for network traffic originating from the management port.
Configuring a Username and Password
To access the system remotely, configure a system username and password.
To configure a system username and password, use the following command.
• Configure a username and password to access the system remotely.
CONFIGURATION mode
username username password [encryption-type] password
– encryption-type: specifies how you are inputting the password, is 0 by default, and is not
required.
* 0 is for inputting the password in clear text.
* 7 is for inputting a password that is already encrypted using a Type 7 hash. Obtaining the
encrypted password from the configuration of another S5000 switch.
Creating a Port-based VLAN
The default virtual local area network (VLAN) (VLAN 1) is part of the system startup configuration and
does not require configuration.
To configure a port-based VLAN, create the VLAN and then add physical interfaces or port channel (LAG)
interfaces to the VLAN.
• Configure a port-based VLAN (if the vlan-id is different from the default VLAN ID) and enter
INTERFACE VLAN mode.
CONFIGURATION mode
interface vlan vlan-id
After you create a VLAN, to activate the VLAN, assign interfaces in Layer 2 mode to the VLAN.
To view the configured VLANs, use the show vlan command in EXEC Privilege mode.
Assigning Interfaces to a VLAN
You can only assign interfaces in Layer 2 mode to a VLAN using the tagged and untagged commands.
To place an interface in Layer 2 mode, use the switchport command.
You can designate Layer 2 interfaces as tagged or untagged. When you place an interface in Layer 2
mode using the switchport command, the interface is automatically designated untagged and placed
in the default VLAN.
To view which interfaces are tagged or untagged and to view which VLAN the interfaces belong, use the
show vlan command. To view just the interfaces that are in Layer 2 mode, use the show interfaces
switchport
command in EXEC Privilege mode or EXEC mode.
56
Getting Started
To tag frames leaving an interface in Layer 2 mode, assign that interface to a port-based VLAN to tag it
with that VLAN ID.
1. Access the INTERFACE VLAN mode of the VLAN to which you want to assign the interface.
CONFIGURATION mode
interface vlan vlan-id
2. Enable an interface to include the IEEE 802.1Q tag header.
INTERFACE mode
tagged interface
3. To move untagged interfaces from the default VLAN to another VLAN, use the untagged command.
Access the INTERFACE VLAN mode of the VLAN to which you want to assign the interface.
CONFIGURATION mode
interface vlan vlan-id
4. Configure an interface as untagged. This command is available only in VLAN interfaces.
INTERFACE mode
untagged interface
Assigning an IP Address to a VLAN
VLANs are a Layer 2 feature. For two physical interfaces on different VLANs to communicate, assign an IP
address to the VLANs to route traffic between the two interfaces. The shutdown command in
INTERFACE mode does not affect Layer 2 traffic on the interface.
NOTE: You cannot assign an IP address to the default VLAN, which, by default, is VLAN1. To assign
another VLAN ID to the default VLAN, use the default vlan-id vlan-id command.
• Configure an IP address and mask on the interface.
INTERFACE mode
ip address ip-address mask [secondary]
Connect the S5000 to the Network
After you have completed the hardware installation and software configuration for the S5000 system, you
can connect to your company network by following your company’s cabling requirements.
Configure File Management
You can store on and access files from various storage media. Rename, delete, and copy files on the
system from the EXEC Privilege mode.
NOTE: Using flash memory cards in the system that have not been approved by Dell Networking
can cause unexpected system behavior, including a reboot.
Getting Started
57
Copying Files to and from the System
The command syntax for copying files is similar to UNIX. The copy command uses the format copy
source-file-url destination-file-url.
NOTE: For a detailed description of the copy command, refer to the Dell Networking OS Command
Line Reference Guide.
• To copy a local file to a remote system, combine the file-origin syntax for a local file location with the
file-destination syntax for a remote file location.
• To copy a remote file to Dell Networking system, combine the file-origin syntax for a remote file
location with the file-destination syntax for a local file location.

Important Points to Remember
• You may not copy a file from one remote system to another.
• You may not copy a file from one location to the same location.
• When copying to a server, you can only use a hostname if a domain name server (DNS) server is
configured.
• After you insert a USB memory device into the USB port on an S5000 and enter the format
usbflash:// command, to erase all existing files and reformat the file system on the device, allow
the process to run to completion before removing the device from the USB port. If you remove the
USB memory device before the formatting is complete, the Dell Networking OS may not recognize
the file system on the device.
Example of Copying a file to a Remote System
The following shows an example of using the copy command to save a file to an FTP server.

Mounting an NFS File System
This feature enables you to quickly access data on an NFS mounted file system. You can perform file
operations on an NFS mounted file system using supported file commands.
This feature allows an NFS mounted device to be recognized as a file system. This file system is visible on
the device and you can execute all file commands that are available on conventional file systems such as
a Flash file system.
Before executing any CLI command to perform file operations, you must first mount the NFS file system
to a mount-point on the device. Since multiple mount-points exist on a device, it is mandatory to specify
the mount-point to which you want to load the system. The /f10/mnt/nfsdirectory is the root of all
mount-points.
To mount an NFS file system, perform the following steps:
Table 4. Mounting an NFS File System
File Operation Syntax
To mount an NFS file system:
The foreign file system remains mounted as long as the device is up and does not reboot. You can run
the file system commands without having to mount or un-mount the file system each time you run a
command. When you save the configuration using the write command, the mount command is saved
to the startup configuration. As a result, each time the device re-boots, the NFS file system is mounted
during start up.

Saving the Running-Configuration
The running-configuration contains the current system configuration. Dell Networking recommends
coping your running-configuration to the startup-configuration.
The system uses the startup-configuration during boot-up to configure the system. The startupconfiguration is stored in the internal flash on the IOM by default, but you can save the startupconfiguration to a USB flash device or on a remote server.
NOTE: The commands in this section follow the same format as those in Copying Files to and from
the System but use the filenames startup-configuration and running-configuration. These
commands assume that current directory is the internal flash, which is the system default.
• Save the running-configuration to the startup-configuration on the internal flash.

View Configuration Files
Configuration files have three commented lines at the beginning of the file, as shown in the following
example, to help you track the last time any user made a change to the file, which user made the
changes, and when the file was last saved to the startup-configuration.
In the running-configuration file, if there is a difference between the timestamp on the “Last
configuration change,” and “Startup-config last updated,” you have made changes that have not been
saved and will not be preserved after a system reboot.

Compressing Configuration Files
The functionality to optimize and reduce the sizes of the configuration files is supported on the device.
You can compress the running configuration by grouping all the VLANs and the physical interfaces with
the same property. Support to store the operating configuration to the startup config in the compressed
mode and to perform an image downgrade without any configuration loss are provided.
You can create groups of VLANs using the interface group command. This command will create
non-existant VLANs specified in a range. On successful command execution, the CLI switches to the
interface group context. The configuration commands inside the group context will be the similar to that
of the existing range command.
Two existing exec mode CLIs are enhanced to display and store the running configuration in the
compressed mode.
show running-config compressed and write memory compressed
The compressed configuration will group all the similar looking configuration thereby reducing the size
of the configuration. For this release, the compression will be done only for interface related
configuration (VLAN & physical interfaces)

Enabling Software Features on Devices Using a Command Option
This capability to activate software applications or components on a device using a command is
supported on the S4810, S4820T, and S6000, platforms.
Starting with Release 9.4(0.0), you can enable or disable specific software functionalities or applications
that need to run on a device by using a command attribute in the CLI interface. This capability enables
effective, streamlined management and administration of applications and utilities that run on a device.
You can employ this capability to perform an on-demand activation or turn-off of a software component
or protocol. A feature configuration file that is generated for each image contains feature names denotes
whether this enabling or disabling method is available for such features. In 9.4(0.0), you can enable or
disable the VRF application globally across the system by using this capability.
You can activate VRF application on a device by using the feature vrf command in CONFIGURATION
mode.
NOTE: The no feature vrf command is not supported on any of the platforms.
To enable the VRF feature and cause all VRF-related commands to be available or viewable in the CLI
interface, use the following command. You must enable the VRF feature before you can configure its
related attributes.
Dell(conf)# feature vrf
Based on whether VRF feature is identified as supported in the Feature Configuration file, configuration
command feature vrf becomes available for usage. This command will be stored in running-configuration
and will precede all other VRF-related configurations.
NOTE: The MXL and Z9000 platforms currently do not support VRF. These platforms support only
the management and default VRFs, which are available by default. As a result, the feature vrf
command is not available for these platforms.
To display the state of Dell Networking OS features:
Dell#show feature
Example of show feature output
For a particular target where VRF is enabled, the show output is similar to the following:

Upgrading and Downgrading Dell Networking OS
To upgrade or downgrade Dell Networking OS, refer to the Release Notes for the version you want to
load on the system.
Using Hashes to Validate Software Images
You can use the MD5 message-digest algorithm or SHA256 Secure Hash Algorithm to validate the
software image on the flash drive, after the image has been transferred to the system, but before the
image has been installed. The validation calculates a hash value of the downloaded image file on system’s
flash drive, and, optionally, compares it to a Dell Networking published hash for that file.
The MD5 or SHA256 hash provides a method of validating that you have downloaded the original
software. Calculating the hash on the local image file, and comparing the result to the hash published for
that file on iSupport, provides a high level of confidence that the local copy is exactly the same as the
published software image. This validation procedure, and the verify {md5 | sha256} command to support
it, can prevent the installation of corrupted or modified images.
The verify {md5 | sha256} command calculates and displays the hash of any file on the specified local
flash drive. You can compare the displayed hash against the appropriate hash published on i-Support.
Optionally, the published hash can be included in the verify {md5 | sha256} command, which will display
whether it matches the calculated hash of the indicated file.
To validate a software image:
1. Download Dell Networking OS software image file from the iSupport page to the local (FTP or TFTP)
server. The published hash for that file is displayed next to the software image file on the iSupport
page.
2. Go on to the Dell Networking system and copy the software image to the flash drive, using the copy
command.
3. Run the verify {md5 | sha256} [ flash://]img-file [hash-value] command. For example, verify sha256
flash://FTOS-SE-9.5.0.0.bin
4. Compare the generated hash value to the expected hash value published on the iSupport page.
68
Getting Started
To validate the software image on the flash drive after the image has been transferred to the system, but
before the image has been installed, use the verify {md5 | sha256} [ flash://]img-file [hash-value]
command in EXEC mode.
• md5: MD5 message-digest algorithm
• sha256: SHA256 Secure Hash Algorithm
• flash: (Optional) Specifies the flash drive. The default is to use the flash drive. You can just enter the
image file name.
• hash-value: (Optional). Specify the relevant hash published on i-Support.
• img-file: Enter the name of the Dell Networking software image file to validate

Switch Management
This chapter explains the different protocols or services used to manage the S5000 switch.
Configuring Privilege Levels
Privilege levels restrict access to commands based on user or terminal line.
There are 16 privilege levels, of which three are pre-defined. The default privilege level is 1.
Level Description
Level 1 Access to the system begins at EXEC mode, and EXEC mode commands are
limited to enable, disable, and exit.
Level 15 Access to the system begins at EXEC Privilege mode, and all commands are
available.
Creating a Custom Privilege Level
Custom privilege levels start with the default EXEC mode command set. You can then customize privilege
levels 2 through 14 by:
• restricting access to an EXEC mode command
• moving commands from EXEC Privilege to EXEC mode
• allowing access to CONFIGURATION mode commands
• allowing access to INTERFACE, LINE, ROUTE-MAP, and ROUTER mode commands
A user can access all commands at his privilege level and below.
Removing a Command from EXEC Mode
To remove a command from the list of available commands in EXEC mode for a specific privilege level,
use the privilege exec command from CONFIGURATION mode.
In the command, specify a level greater than the level given to a user or terminal line, then the first
keyword of each command you wish to restrict.
Moving a Command from EXEC Privilege Mode to EXEC Mode
To move a command from EXEC Privilege to EXEC mode for a privilege level, use the privilege exec
command from CONFIGURATION mode.
In the command, specify the privilege level of the user or terminal line and specify all keywords in the
command to which you want to allow access.
70
Switch Management
Allowing Access to CONFIGURATION Mode Commands
To allow access to CONFIGURATION mode, use the privilege exec level level configure
command from CONFIGURATION mode.
A user that enters CONFIGURATION mode remains at his privilege level and has access to only two
commands, end and exit. You must individually specify each CONFIGURATION mode command you
want to allow access to using the privilege configure level level command. In the command,
specify the privilege level of the user or terminal line and specify all the keywords in the command to
which you want to allow access.
Allowing Access to the Following Modes
This section describes how to allow access to the INTERFACE, LINE, ROUTE-MAP, and ROUTER modes.
Similar to allowing access to CONFIGURATION mode, to allow access to INTERFACE, LINE, ROUTE-MAP,
and ROUTER modes, first allow access to the command that enters you into the mode. For example, to
allow a user to enter INTERFACE mode, use the
gigabitethernet
Next, individually identify the INTERFACE, LINE, ROUTE-MAP or ROUTER commands to which you want
to allow access using the privilege {interface | line | route-map | router} level
level command. In the command, specify the privilege level of the user or terminal line and specify all
the keywords in the command to which you want to allow access.
To remove, move or allow access, use the following commands.
The configuration in the following example creates privilege level 3. This level:
command.
privilege configure level level interface
• removes the resequence command from EXEC mode by requiring a minimum of privilege level 4
• moves the capture bgp-pdu max-buffer-size command from EXEC Privilege to EXEC mode by
requiring a minimum privilege level 3, which is the configured level for VTY 0
• allows access to CONFIGURATION mode with the banner command
• allows access to INTERFACE and LINE modes are allowed with no commands
• Remove a command from the list of available commands in EXEC mode.

Configuring Logging
The Dell Networking OS tracks changes in the system using event and error messages.
By default, Dell Networking OS logs these messages on:
• the internal buffer
• console and terminal lines
• any configured syslog servers
To disable logging, use the following commands.
• Disable all logging except on the console.
CONFIGURATION mode
no logging on
• Disable logging to the logging buffer.
CONFIGURATION mode

Log Messages in the Internal Buffer
All error messages, except those beginning with %BOOTUP (Message), are log in the internal buffer.
Configuration Task List for System Log Management
There are two configuration tasks for system log management:
• Disabling System Logging
• Sending System Messages to a Syslog Server
Disabling System Logging
By default, logging is enabled and log messages are sent to the logging buffer, all terminal lines, the
console, and the syslog servers.
To disable system logging, use the following commands.
• Disable all logging except on the console.
CONFIGURATION mode
no logging on
• Disable logging to the logging buffer.

Switch Management
Configuring a UNIX System as a Syslog Server
To configure a UNIX System as a syslog server, use the following command.
• Configure a UNIX system as a syslog server by adding the following lines to /etc/syslog.conf on the
UNIX system and assigning write permissions to the file.
– Add line on a 4.1 BSD UNIX system. local7.debugging /var/log/ftos.log
– Add line on a 5.7 SunOS UNIX system. local7.debugging /var/adm/ftos.log
In the previous lines, local7 is the logging facility level and debugging is the severity level.
Changing System Logging Settings
You can change the default settings of the system logging by changing the severity level and the storage
location.
The default is to log all messages up to debug level, that is, all system messages. By changing the severity
level in the logging commands, you control the number of system messages logged.
To specify the system logging settings, use the following commands.
• Specify the minimum severity level for logging to the logging buffer.

Synchronizing Log Messages
You can configure Dell Networking OS to filter and consolidate the system messages for a specific line by
synchronizing the message output.
Only the messages with a severity at or below the set level appear. This feature works on the terminal and
console connections available on the system.
1. Enter LINE mode.
CONFIGURATION mode
line {console 0 | vty number [end-number] | aux 0}
Configure the following parameters for the virtual terminal lines:
• number: the range is from zero (0) to 9.
• end-number: the range is from 1 to 8.
You can configure multiple virtual terminals at one time by entering a number and an end-number.
2. Configure a level and set the maximum number of messages to print.
LINE mode
logging synchronous [level severity-level | all] [limit]
Configure the following optional parameters:
• level severity-level: the range is from 0 to 7. The default is 2. Use the all keyword to
include all messages.
• limit: the range is from 20 to 300. The default is 20.
To view the logging synchronous configuration, use the show config command in LINE mode.
Enabling Timestamp on Syslog Messages
By default, syslog messages do not include a time/date stamp stating when the error or message was
created.
To enable timestamp, use the following command.
• Add timestamp to syslog messages.
CONFIGURATION mode
service timestamps [log | debug] [datetime [localtime] [msec] [show-timezone]
| uptime]
Specify the following optional parameters:
– You can add the localtime keyword to include the localtime, msec, and show-timezone. If
you do not add the localtime keyword, the time is UTC.

Switch Management
– uptime: To view time since last boot.
If you do not specify a parameter, Dell Networking OS configures uptime.
To view the configuration, use the show running-config logging command in EXEC privilege mode.
To disable time stamping on syslog messages, use the no service timestamps [log | debug]
command.
File Transfer Services
With Dell Networking OS, you can configure the system to transfer files over the network using the file
transfer protocol (FTP).
One FTP application is copying the system image files over an interface on to the system; however, FTP is
not supported on virtual local area network (VLAN) interfaces.
For more information about FTP, refer to RFC 959, File Transfer Protocol.
NOTE: To transmit large files, Dell Networking recommends configuring the switch as an FTP
server.
Configuration Task List for File Transfer Services
The configuration tasks for file transfer services are:
• Enabling the FTP Server
• Configuring FTP Server Parameters
• Configuring FTP Client Parameters
Enabling the FTP Server
To enable the system as an FTP server, use the following command.
To view FTP configuration, use the show running-config ftp command in EXEC privilege mode.

Terminal Lines
You can access the system remotely and restrict access to the system by creating user profiles.
Terminal lines on the system provide different means of accessing the system. The console line (console)
connects you through the console port in the route processor modules (RPMs). The virtual terminal lines
(VTYs) connect you through a remote session to the system. The auxiliary line (aux) connects secondary
devices such as modems.
Denying and Permitting Access to a Terminal Line
Dell Networking recommends applying only standard access control lists (ACLs) to deny and permit
access to VTY lines.
• Layer 3 ACLs deny all traffic that is not explicitly permitted, but in the case of VTY lines, an ACL with
no rules does not deny traffic.
• You cannot use the show ip accounting access-list command to display the contents of an
ACL that is applied only to a VTY line.
To apply an IP ACL to a line, use the following command.
• Apply an ACL to a VTY line.
LINE mode
ip access-class access-list
Example of an ACL that Permits Terminal Access
To view the configuration, use the show config command in LINE mode.
Dell(config-std-nacl)#show config
!
ip access-list standard myvtyacl
seq 5 permit host 10.11.0.1
Dell(config-std-nacl)#line vty 0
Dell(config-line-vty)#show config
line vty 0
access-class myvtyacl
Dell Networking OS Behavior: Prior to Dell Networking OS version 7.4.2.0, in order to deny access on a
VTY line, apply an ACL and accounting, authentication, and authorization (AAA) to the line. Then users are
denied access only after they enter a username and password. Beginning in Dell Networking OS version
7.4.2.0, only an ACL is required, and users are denied access before they are prompted for a username
and password.
Configuring Login Authentication for Terminal Lines
You can use any combination of up to six authentication methods to authenticate a user on a terminal
line.
A combination of authentication methods is called a method list. If the user fails the first authentication
method, Dell Networking OS prompts the next method until all methods are exhausted, at which point
the connection is terminated. The available authentication methods are:
Switch Management
81
enable

1. Configure an authentication method list. You may use a mnemonic name or use the keyword
default. The default authentication method for terminal lines is local and the default method list is
empty.
CONFIGURATION mode
aaa authentication login {method-list-name | default} [method-1] [method-2]
[method-3] [method-4] [method-5] [method-6]
2. Apply the method list from Step 1 to a terminal line.
CONFIGURATION mode

Lock CONFIGURATION Mode
Dell Networking OS allows multiple users to make configurations at the same time. You can lock
CONFIGURATION mode so that only one user can be in CONFIGURATION mode at any time (Message
2).
You can set two types of lockst: auto and manual.
• Set auto-lock using the configuration mode exclusive auto command from
CONFIGURATION mode. When you set auto-lock, every time a user is in CONFIGURATION mode, all
other users are denied access. This setting means that you can exit to EXEC Privilege mode, and reenter CONFIGURATION mode without having to set the lock again.
• Set manual lock using the configure terminal lock command from CONFIGURATION mode.
When you configure a manual lock, which is the default, you must enter this command each time you
want to enter CONFIGURATION mode and deny access to others.
Viewing the Configuration Lock Status
If you attempt to enter CONFIGURATION mode when another user has locked it, you may view which
user has control of CONFIGURATION mode using the show configuration lock command from
EXEC Privilege mode.
You can then send any user a message using the send command from EXEC Privilege mode.
Alternatively, you can clear any line using the
console session, the user is returned to EXEC mode.
Example of Locking CONFIGURATION Mode

802.1ag
Ethernet operations, administration, and maintenance (OAM) are a set of tools used to install, monitor,
troubleshoot, and manage Ethernet infrastructure deployments. Ethernet OAM consists of three main
areas:
• Service layer OAM — IEEE 802.1ag connectivity fault management (CFM)
• Link layer OAM — IEEE 802.3ah OAM
• Ethernet local management Interface — (MEF-16 E-LMI)
Ethernet CFM
Ethernet CFM is an end-to-end per-service-instance Ethernet OAM scheme which enables: proactive
connectivity monitoring, fault verification, and fault isolation.
The service-instance regarding OAM for Metro/Carrier Ethernet is a virtual local area network (VLAN). This
service is sold to an end-customer by a network service provider. Typically the service provider contracts
with multiple network operators to provide end-to-end service between customers. For end-to-end
service between customer switches, connectivity must be present across the service provider through
multiple network operators.
Layer 2 Ethernet networks usually cannot be managed with IP tools such as internet control message
protocol (ICMP) Ping and IP Traceroute. Traditional IP tools often fail because:
• there are complex interactions between various Layer 2 and Layer 3 protocols such as spanning tree
protocol (STP), link aggregation group (LAG), virtual router redundancy protocol (VRRP), and
electronic commerce messaging protocol (ECMP) configurations.
• ping and traceroute are not designed to verify data connectivity in the network and within each node
in the network (such as in the switching fabric and hardware forwarding tables).
• when networks are built from different operational domains, access controls impose restrictions that
cannot be overcome at the IP level, resulting in poor fault visibility. There is a need for hierarchical
domains that are monitored and maintained independently by each provider or operator.
• routing protocols choose a subset of the total network topology for forwarding, making it hard to
detect faults in links and nodes that are not included in the active routing topology. This is made more
complex when using some form of traffic engineering (TE) based routing.
• network and element discovery and cataloging is not clearly defined using IP troubleshooting tools.
There is a need for Layer 2 equivalents to manage and troubleshoot native Layer 2 Ethernet networks.
With these tools, you can identify, isolate, and repair faults quickly and easily, which reduces operational
cost of running the network. OAM also increases availability and reduces mean time to recovery, which
allows for tighter service level agreements, resulting in increased revenue for the service provider.
88
802.1ag
In addition to providing end-to-end OAM in native Layer 2 Ethernet Service Provider/Metro networks, you
can also use CFM to manage and troubleshoot any Layer 2 network including enterprise, datacenter, and
cluster networks.
Maintenance Domains
Connectivity fault management (CFM) divides a network into hierarchical maintenance domains, as
shown in the following illustration.
A CFM maintenance domain is a management space on a network that a single management entity owns
and operates. The network administrator assigns a unique maintenance level (from 0 to 7) to each
domain to define the hierarchical relationship between domains. Domains can touch or nest but cannot
overlap or intersect as that would require management by multiple entities.
Figure 3. OAM Domains
Maintenance Points
Domains are comprised of logical entities called maintenance points.
A maintenance point is an interface demarcation that confines CFM frames to a domain. There are two
types of maintenance points:
• Maintenance end points (MEPs) — a logical entity that marks the end point of a domain.
• Maintenance intermediate points (MIPs) — a logical entity configured at a port of a switch that is an
intermediate point of a maintenance entity (ME). An ME is a point-to-point relationship between two
MEPs within a single domain. MIPs are internal to a domain, not at the boundary, and respond to CFM
only when triggered by linktrace and loopback messages. You can configure MIPs to snoop continuity
check Messages (CCMs) to build a MIP CCM database.
These roles define the relationships between all devices so that each device can monitor the layers under
its responsibility. Maintenance points drop all lower-level frames and forward all higher-level frames.
802.1ag
89
Figure 4. Maintenance Points
Maintenance End Points
A maintenance end point (MEP) is a logical entity that marks the end point of a domain.
There are two types of MEPs defined in 802.1ag for an 802.1 bridge:
• Up-MEP — monitors the forwarding path internal to a bridge on the customer or provider edge. On
Dell Networking systems, the internal forwarding path is effectively the switch fabric and forwarding
engine.
• Down-MEP — monitors the forwarding path external another bridge.
Configure Up-MEPs on ingress ports, ports that send traffic towards the bridge relay. Configure DownMEPs on egress ports, ports that send traffic away from the bridge relay.
Figure 5. Maintenance End Points

802.1ag
Implementation Information
Because the S5000 has a single MAC address for all physical/LAG interfaces, only one MEP is allowed per
MA (per VLAN or per MD level).
Configuring the CFM
To configure the CFM, follow these steps:
1. Configure the ecfmacl CAM region using the cam-acl command. Refer to Configure Ingress ACLs.
2. Enabling Ethernet CFM
3. Creating a Maintenance Domain
4. Creating a Maintenance Association
5. Create Maintenance Points
6. Use CFM tools:
a. Continuity Check Messages
b. Sending Loopback Messages and Responses
c. Sending Linktrace Messages and Responses

Creating a Maintenance Association
A maintenance association (MA) is a subdivision of an MD that contains all managed entities
corresponding to a single end-to-end service, typically a virtual area network (VLAN).
An MA is associated with a VLAN ID.
• Create maintenance association.
ECFM DOMAIN mode

Create Maintenance Points
Domains are comprised of logical entities called maintenance points. A maintenance point is an interface
demarcation that confines CFM frames to a domain.
There are two types of maintenance points:
• Maintenance End Points (MEPs) — a logical entity that marks the end point of a domain.
• Maintenance Intermediate Points (MIPs) — a logical entity configured at a port of a switch that
constitutes intermediate points of a Maintenance Entity (ME). An ME is a point-to-point relationship
between two MEPs within a single domain.
These roles define the relationships between all devices so that each device can monitor the layers under
its responsibility.

Displaying the MP Databases
CFM maintains two MP databases:
• MEP Database (MEP-DB) — Every MEP must maintain a database of all other MEPs in the MA that have
announced their presence via CCM.
• MIP Database (MIP-DB) — Every MIP must maintain a database of all other MEPs in the MA that have
announced their presence via CCM.
To display the MEP and MIP databases, use the following commands.
• Display the MEP Database.
EXEC Privilege mode
show ethernet cfm maintenance-points remote detail [active | domain {level |
name} | expired | waiting]
• Display the MIP Database.
EXEC Privilege mode

802.1ag
Continuity Check Messages
Continuity check messages (CCM) are periodic hellos.
Continuity check messages:
• discover MEPs and MIPs within a maintenance domain
• detect loss of connectivity between MEPs
• detect misconfiguration, such as VLAN ID mismatch between MEPs
• to detect unauthorized MEPs in a maintenance domain
CCMs are multicast Ethernet frames sent at regular intervals from each MEP. They have a destination
address based on the MD level (01:80:C2:00:00:3X where X is the MD level of the transmitting MEP from
0 to 7). All MEPs must listen to these multicast MAC addresses and process these messages. MIPs may
optionally process the CCM messages the MEPs originate and construct a MIP CCM database.
MEPs and MIPs filter CCMs from higher and lower domain levels as described in the following table.
Table 6. Continuity Check Message Processing
Frames at Frames from UP-MEP Action Down-MEP Action MIP Action
Less than my level Bridge-relay side or
Wire side
My level Bridge-relay side Consume Drop Add to MIP-DB and
My level Wire side Drop Consume Add to MIP-DB and
Greater than my
level
All the remote MEPs in the maintenance domain are defined on each MEP. Each MEP then expects a
periodic CCM from the configured list of MEPs. A connectivity failure is then defined as:
• Loss of three consecutive CCMs from any of the remote MEP, which indicates a network failure.
• Reception of a CCM with an incorrect CCM transmission interval, which indicates a configuration
error.
• Reception of a CCM with an incorrect MEP ID or MAID, which indicates a configuration or crossconnect error. This error could happen when different VLANs are cross-connected due to a
configuration error.
• Reception of a CCM with an MD level lower than the receiving MEP, which indicates a configuration
or cross-connect error.
• Reception of a CCM containing a port status/interface status TLV, which indicates a failed bridge or
aggregated port.
The continuity check protocol sends fault notifications (Syslogs, and SNMP traps, if enabled) whenever
you encounter any of these errors.

Sending Loopback Messages and Responses
Loopback message and response (LBM, LBR), also called Layer 2 Ping, is an administrative echo
transmitted by MEPs to verify reachability to another MEP or MIP within the maintenance domain. LBM
and LBR are unicast frames.
• Send a Loopback message
EXEC Privilege mode

96
802.1ag
Sending Linktrace Messages and Responses
Linktrace message and response (LTM, LTR), also called Layer 2 Traceroute, is an administratively sent
multicast frame transmitted by MEPs to track, hop-by-hop, the path to another MEP or MIP within the
maintenance domain.
All MEPs and MIPs in the same domain respond to an LTM with a unicast LTR. Intermediate MIPs forward
the LTM toward the target MEP.
Figure 6. MPLS Core
Link trace messages carry a unicast target address (the MAC address of an MIP or MEP) inside a multicast
frame. The destination group address is based on the MD level of the transmitting MEP
(01:80:C2:00:00:3[8 to F]). The MPs on the path to the target MAC address reply to the LTM with an LTR,
and relays the LTM towards the target MAC until the target MAC is reached or TTL equals 0.
• Send a Linktrace message. Because the LTM is a Multicast message sent to the entire ME, there is no
need to specify a destination.
