how to upgrade the system software, protecting the switch from outside attacks etc.).
Chapter 5: Configuring Switch Authentication Features - The Command Line Interface
supports privilege levels of access to commands that can be used for protecting the system from
unauthorized access. The chapter describes the SSH Secure Shell protocol which provides a secure,
remote connection to the switches. Additionally, it describes the TACACS+ security protocol for
remote Authentication, Authorization and/or Accounting. Also included in this chapter is the
RADIUS client/server protocol for carrying authentication, authorization, and configuration
information between a Network Access Server (Switch).
Chapter 6: Configuring Interfaces - describes the switching frames between segments, and
explains how to build the address table and how to configure and display the Fast Ethernet and
Giga Ethernet Ports. The chapter also deals with static link aggregation groups (LAGs). It explains
how to establish resilience across all segments of a network which feature provides fault recovery
that is so fast that faults are actually transparent to network applications or users. Information on
the Alarm Propagation feature and Remote Loopback feature can also be found in this chapter.
Chapter 7: Configuring VLANs - explains how to create and maintain VLANs. The chapter
includes information about the VLAN database, VLAN configuration modes, etc. It contains
information about VLAN-related features such as Super VLAN and the GARP VLAN registration
protocol.

across an Ethernet ring-based service provider network. Also included are GARP Multicast
Registration and IGMP Snooping along with information on how to configure these protocols.
Chapter 15: Configuring Quality of Service (QoS) - describes the QoS that allows the user to
specify different service levels for traffic that traverses the switch. Policy-based QoS is an effective
control mechanism for networks that have heterogeneous traffic patterns. Using Policy-based QoS,
the user can specify the service level for a traffic type or host.
Chapter 16: Configuring Hierarchical Quality of Service (HQoS) - explains how to configure
the HQoS feature.
Chapter 17: Configuring Access Control List (ACL) - explains how to create ACLs, traffic rate
limit, traffic redirection and how to obtain QoS by using ACL.
Chapter 18: Configuring Routing Information - describes the configuration and management
of routing and related protocols and features, such as ICMP Router Discovery Protocol (IRDP).
The chapter also describes Proxy ARP between subnets and the advantages and drawbacks of using
Proxy ARP, a broadcast directed to a specified network prefix and how to configure directed
broadcast.
Chapter 19: Configuring Advanced Routing Information - provides in-depth explanation of
the implementation of the Open Shortest Path First protocol. The chapter also includes information
about Bidirectional Forwarding Detection (BFD) that is intended to validate the operation of the
LSP or the IP routing neighbor.
Chapter 20: Network Administration Tools - describes the tools and utilities for installing,
monitoring and troubleshooting the network. The chapter includes information about 802.3ah
EFM-OAM functionality that provides reliable service assurance mechanisms both for provider
and for customer networks. Also, described are 802.1ag CFM functionality, which allows
monitoring of services, and MEF OAM, which provides connectivity tests. The chapter also
includes information about Response Time Reporter (RTR) and SAA (Service Assurance
Application), software that allows the user to monitor the performance of network-hosted
applications by emulating the traffic of these application.. SAA provides the capability of
controlling and provisioning various OAM tests and SAA monitoring.
Chapter 21: Configuring SAA via SNMP - describes how to configure SAA (Service Assurance
Application) via SNMP.
Chapter 22:
Configuring Remote Monitoring (RMON) - explains how to configure the RMON
feature, which is used with the Simple Network Management Protocol (SNMP) agent in the switch,
to allow the user to monitor all the traffic flowing among switches on all connected LAN segments.

Overview
The configuration program uses a CLI (Command Line Interface) that enables the user to start
using the device quickly and without extensive background knowledge. It does this by prompting
the user for the information required to perform basic configuration procedures.
The device can run with the default factory parameters. After changing the default factory
parameters, be sure to save the changes in the NVRAM.

prompt is displayed, allowing the user to begin the configuration process.
Basic CLI Operating Conventions
When the user enters commands at the CLI prompt and then press the <Enter> key, the CLI
responds with information based on the entered commands, and passes the commands on to be
executed by the software.
The user types all commands on one line and then press <Enter>. The CLI response is displayed on
the screen.
The user may abbreviate CLI commands down to the least number of leading characters that are
not ambiguous in the available vocabulary. For example, the user may enter the letters sho for the
show command.
If the CLI requires more than one screen to respond to certain commands, it displays the following
prompt at the bottom of each but the last screen:
--More--
If this prompt appears, press on the space bar to continue to the next screen.
Special Keys
Table 1 describes special keys available at the CLI prompt.

device-name>keyword(s) [argument(s)] ... [keyword(s)] [argument(s)]
or
device-name[(config ...)]#keyword(s) [argument(s)] ... [keyword(s)]
[argument(s)]
where:
•The angle bracket (>) is the CLI prompt symbol in View mode.
•The pound symbol (#) is the CLI prompt symbol in all other modes.
•The left part, up to and including the prompt symbol represents the command prompt displayed
by the computer. In this part:
oThe optional expression “(config ...)”– including the parentheses – appears on the
screen exactly as in the manual.

Foundry NetIron M2404C and M2404F Metro Access Switches Using the Command Line Interface (Rev. 03)
Getting Started with the CLI © 2008 Foundry Networks, Inc. Page 6 of 12
oThe part following the prompt symbol represents the command. Table 2 lists the
symbols and word-formatting used in the CLI command syntax descriptions.
Table 2: CLI Command Syntax Conventions
Symbol/Format Description
<> Numerical argument.
[] Optional argument or keyword.
{ | } ORsign, between two arguments or keywords.
Bold letters Keyword.
Italic, small letters Numerical argument.
ITALIC IN CAPITALS Non-numerical argument.
A.B.C.D IP address.
UU/SS/PP Physical interface in unit/slot/port numbers.
CLI Modes
The command language interface is divided into several CLI modes and associated prompt levels.
The prompt appears as a string starting with the device-name and ending with an angle bracket (>)
or pound symbol (#), depending on the prompt level. The current CLI mode determines the
available commands. Enter a question mark (?) at the system prompt to obtain a list of commands
available for each command mode.
View Mode (User-level)
When a session is started, the user begins in View mode. Only a limited number of CLI commands
are available in View mode. The View mode allows viewing capabilities only. The View mode
prompt is an angle bracket (>):
device-name>
There is no default password. The user can configure a password by using the password command
in Global Configuration mode.
Privileged (Enable) Mode
To have access to the commands, the user must enter Privileged (Enable) mode. The Privileged
(Enable) mode allows advanced viewing of the device capabilities and limited configuration
capabilities. Its prompt is a pound symbol (#):
device-name#
By default, Privileged (Enable) mode is not password-protected. However, the user can configure
password protection by using the enable password in the Global Configuration mode.
To access the Privileged (Enable) mode from the View mode, use the enable command.
device-name>enable

Foundry NetIron M2404C and M2404F Metro Access Switches Using the Command Line Interface (Rev. 03)

device-name#
Configuration Modes
Using the configuration modes (Global, Interface, etc.), the user can make changes to the device
configuration. If the user saves the configuration, these commands are stored and used after
rebooting. To access the various configuration modes, the user must start at Global Configuration
mode.
The Global Configuration mode allows full configuration capabilities. Its prompt is displayed as
follows:
device-name(config)#
Additional information can be displayed inside the parentheses, before the pound symbol, to
indicate the present configuration mode.
The following example indicates that the CLI is in Protocol Configuration mode:
device-name(cfg protocol)#
To access the Global Configuration mode:
Type the enable command at the EXEC prompt:
device-name>enable
The system displays the privileged-level prompt:
device-name#
To access the Configuration mode:
Type the configure terminal command, in Privileged (Enable) mode.
device-name#configure terminal
The following prompt is displayed, indicating that the CLI has entered into Global Configuration
mode:

CLI Messages
The user might encounter some error messages while using the CLI to configure the device.
Several messages may be issued in response to incorrect entries (e.g., wrong syntax, or incomplete
commands). The following are some of these messages:
•When the user enters a string that is not a command:
% is not recognized
•When the user types a valid command but fail to enter all its required arguments. Press the
<Tab> key to display the possible options.
% command incomplete
•Other messages are displayed if the user enters too few characters. The CLI detects an
ambiguity and displays the possible matches:
% Ambiguous token : w
% It matches the following tokens : who write
Command History
The operating system provides a history or record of commands that the user has entered. This
feature is particularly useful for recalling long or complex commands or entries, including access
lists. A memory buffer in the device retains the last 20 entered commands. For more information
see chapter “Configuring System Message Logging”.
Using no Forms of Commands
Most configuration commands also have a no form. In general, use the no form to disable a feature
or function or reverse the action of a command. The no forms of some commands also return a
feature or function to its default value.
Dynamic Completion of the Arguments
The CLI allows automatic completion of arguments (VLAN-names, interface-names, file-names,
etc.) with their actual (current) values.
For example, if the user enters interface in configuration node and press the <TAB> key, a list of
currently configured interfaces on the device is displayed:
device-name(config)#interface <TAB>
UU/SS/PP ag01 ag02 ag03 ag04 ag05 ag06
ag07 ag08 ag09 ag10 ag11 ag12 ag13

Command Aliases
The CLI allows the user to associate a contiguous character string as an alias to any command,
optionally including specific arguments. This user-defined alias is then fully equivalent to the
command expression to which the user has associated it, in the CLI mode in which the user has
defined the alias. The user can thus set a substitute name for a command and use this name instead
of typing the command again.
For example, the user can assign an alias to the show interface 1/1/1 statistics command, by
typing:
device-name#alias sint1 show interface 1/1/1 statistics
Once the alias is assigned, the user can execute the show interface 1/1/1 statistics command by
simply typing sint1 in the mode in which it was assigned (the Privileged mode):
device-name#sint1

Last5minOutPkts 0 Last5minOutBps 0
To remove the alias sint, type:
device-name#no alias sint1
Filtering the Output of a show Command
The CLI allows the filtering of associated sections of output from the show commands. Filtering
the output of a show command to match a specific regular expression (text string) provides control
over the type and amount of information that is displayed by the system. Filtering is useful, when
displaying large files, for example the configuration file.
The pipe (“|”) character indicates a filtering action. If the include or exclude keyword is not
specified, include is the default.
Syntax Description
device-name#show COMMAND |[include |exclude] REGEXP
Argument Description
COMMAND Any CLI command.

Foundry NetIron M2404C and M2404F Metro Access Switches Using the Command Line Interface (Rev. 03)
Getting Started with the CLI © 2008 Foundry Networks, Inc. Page 11 of 12
| To search the output of show commands, enter the pipe character (the vertical
bar).
include (Optional). Includes only the lines that contain a specified regular expression. This
is the default when no keyword is specified.
exclude (Optional). Excludes any lines that contain a specified regular expression.
REGEXP Any regular-expression (text string) found in show command output.
Example
The following example demonstrates the filtering characteristics of the show running
config command. In this example, only the lines in the configuration file that contain “interface”
are displayed:
device-name#show running-config | include interface
Building the configuration ...
interface 1/1/1
interface 1/1/2
interface 1/1/3
interface 1/1/4
interface 1/1/5
interface 1/1/6
...
General Commands
Table 4 lists the commands the user can use at all times, regardless of the type of the prompt
displayed.
Table 4: General Commands
Command Description
exit Escape current mode and go to previous mode.
help Displays help information.
quit Disconnect and log out.
end Escape current mode and go to Privileged (Enable) mode.
Using Telnet
Any workstation with a Telnet facility should be able to communicate with the device over a
TCP/IP network. Up to five active Telnet sessions can access the device concurrently. The Telnet
session will be disconnected after a specified time of inactivity. For more information regarding
Telnet refer to chapter “Switch Setup and Maintenance”.
Before the user can start a Telnet session, the user must set up the IP parameters described in
chapter “Switch Setup and Maintenance”.
