About This Manual
This document describes command-line interface (CLI) commands you use to view and configure
7200 Series Switches software. You can access the CLI by using a direct connection to the serial
port or by using telnet or SSH over a remote network connection.
Audience
This document is for system administrators who configure and operate systems using 7200 Series
Switches software. It provides an understanding of the configuration options of the software.
Software engineers who integrate software into their hardware platform can also benefit from a
description of the configuration options.
This document assumes that the reader has an understanding of the software base and has read the
appropriate specification for the relevant networking device platform. It also assumes that the
reader has a basic knowledge of Ethernet and networking concepts.
Refer to the release notes for the application-level code. The release notes detail the platformspecific functionality of the Switching, Routing, SNMP, Configuration, Management, and other
packages. The suite of features the packages support is not available on all the platforms to which
software has been ported.
About the Software
The software has two purposes:
• Assist attached hardware in switching frames, based on Layer 2, 3, or 4 information contained
in the frames.
• Provide a complete device management portfolio to the network administrator.
Note: This document contains both standalone and stacking commands.

v1.0, May 2010
Scope
The software encompasses both hardware and software support. The software is partitioned to run
in the following processors:
• CPU – This code runs the networking device management portfolio and controls the overall
networking device hardware. It also assists in frame forwarding, as needed and specified. This
code is designed to run on multiple platforms with minimal changes from platform to
platform.
• Networking device processor – This code does the majority of the packet switching, usually at
wire speed. This code is platform dependent, and substantial changes might exist across
products.
Product Concept
Fast Ethernet and Gigabit Ethernet switching continues to evolve from high-end backbone
applications to desktop switching applications. The price of the technology continues to decline,
while performance and feature sets continue to improve. Devices that are capable of switching
Layers 2, 3, and 4 are increasingly in demand. The software provides a flexible solution to these
ever-increasing needs.
The exact functionality provided by each networking device on which the software base runs
varies depending upon the platform and requirements of the FASTPATH software.
The software includes a set of comprehensive management functions for managing both the
software and the network. You can manage the software by using one of the following three
methods:
• Command-Line Interface (CLI)
• Simple Network Management Protocol (SNMP)
• Web-based
Each of the management methods enables you to configure, manage, and control the software
locally or remotely using in-band or out-of-band mechanisms. Management is standards-based,
with configuration parameters and a private MIB providing control for functions not completely
specified in the MIBs.

Using the Command-Line Interface
The command-line interface (CLI) is a text-based way to manage and monitor the system. You can
access the CLI by using a direct serial connection or by using a remote logical connection with
telnet or SSH.
This chapter describes the CLI syntax, conventions, and modes. It contains the following sections:
• “Command Syntax” on page 1-1
• “Command Conventions” on page 1-2
• “Common Parameter Values” on page 1-3
• “Slot/Port Naming Convention” on page 1-3
• “Using the “No” Form of a Command” on page 1-4
• “Managed Switch Modules” on page 1-5
• “Command Modes” on page 1-5
• “Command Completion and Abbreviation” on page 1-9
• “CLI Error Messages” on page 1-9
• “CLI Line-Editing Conventions” on page 1-10
• “Using CLI Help” on page 1-11
• “Accessing the CLI” on page 1-12
Command Syntax
A command is one or more words that might be followed by one or more parameters. Parameters
can be required or optional values.
Some commands, such as show network or clear vlan, do not require parameters. Other
commands, such as network parms, require that you supply a value after the command. You
must type the parameter values in a specific order, and optional parameters follow required
parameters. The following example describes the network parms command syntax:
Format network parms <ipaddr> <netmask> [gateway]
ProSafe 7200 Managed Switches CLI Manual, Software Version 8.0.3
Using the Command-Line Interface 1-2
v1.0, May 2010
• network parms is the command name.
• <ipaddr> and <netmask> are parameters and represent required values that you must
enter after you type the command keywords.
• [gateway] is an optional parameter, so you are not required to enter a value in place of the parameter.
The CLI Command Reference lists each command by the command name and provides a brief
description of the command. Each command reference also contains the following information:
• Format shows the command keywords and the required and optional parameters.
• Mode identifies the command mode you must be in to access the command.
• Default shows the default value, if any, of a configurable setting on the device.
The show commands also contain a description of the information that the command shows.
Command Conventions
In this document, the command name is in bold font. Parameters are in italic font. You
must replace the parameter name with an appropriate value, which might be a name or number.
Parameters are order dependent.
The parameters for a command might include mandatory values, optional values, or keyword
choices. Table 1 describes the conventions this document uses to distinguish between value types.
Table 1. Parameter Conventions
Symbol Example Description
<> angle brackets <value> Indicates that you must enter a value in place of the
brackets and text inside them.
[] square brackets [value] Indicates an optional parameter that you can enter in
place of the brackets and text inside them.
{} curly braces {choice1 |
choice2}
Indicates that you must select a parameter from the list of
choices.
| Vertical bars choice1 | choice2 Separates the mutually exclusive choices.
[{}] Braces within
square brackets
[{choice1 |
choice2}]
Indicates a choice within an optional element.

Common Parameter Values
Parameter values might be names (strings) or numbers.To use spaces as part of a name parameter,
enclose the name value in double quotes. For example, the expression “System Name with
Spaces” forces the system to accept the spaces. Empty strings (““) are not valid user-defined
strings. Table 2 describes common parameter values and value formatting.
Slot/Port Naming Convention
Managed switch software references physical entities such as cards and ports by using a unit/slot/
port naming convention. The software also uses this convention to identify certain logical entities,
such as Port-Channel interfaces.
Table 2. Parameter Descriptions
Parameter Description
ipaddr This parameter is a valid IP address. You can enter the IP address in the following
formats:
a (32 bits)
a.b (8.24 bits)
a.b.c (8.8.16 bits)
a.b.c.d (8.8.8.8)
In addition to these formats, the CLI accepts decimal, hexadecimal and octal formats
through the following input formats (where n is any valid hexadecimal, octal or decimal
number):
0xn (CLI assumes hexadecimal format)
0n (CLI assumes octal format with leading zeros)
n (CLI assumes decimal format)
ipv6-address FE80:0000:0000:0000:020F:24FF:FEBF:DBCB, or
FE80:0:0:0:20F:24FF:FEBF:DBCB, or
FE80::20F24FF:FEBF:DBCB, or
FE80:0:0:0:20F:24FF:128:141:49:32
For additional information, refer to RFC 3513.
Interface or
unit/slot/port
Valid slot and port number separated by forward slashes. For example, 0/1 represents
slot number 0 and port number 1.
Logical Interface Represents a logical slot and port number. This is applicable in the case of a port-
channel (LAG). You can use the logical unit/slot/port to configure the port-channel.
Character strings Use double quotation marks to identify character strings, for example, “System Name
with Spaces”. An empty string (“”) is not valid.
ProSafe 7200 Managed Switches CLI Manual, Software Version 8.0.3
Using the Command-Line Interface 1-4
v1.0, May 2010
The slot number has two uses. In the case of physical ports, it identifies the card containing the
ports. In the case of logical and CPU ports it also identifies the type of interface or port.
The port identifies the specific physical port or logical interface being managed on a given slot.
Using the “No” Form of a Command
The no keyword is a specific form of an existing command and does not represent a new or
distinct command. Almost every configuration command has a no form. In general, use the no
form to reverse the action of a command or reset a value back to the default. For example, the no
Table 3. Type of Slots
Slot Type Description
Physical slot numbers Physical slot numbers begin with zero, and are allocated up to the maximum
number of physical slots.
Logical slot numbers Logical slots immediately follow physical slots and identify port-channel (LAG) or
router interfaces.
CPU slot numbers The CPU slots immediately follow the logical slots.
Table 4. Type of Ports
Port Type Description
Physical Ports The physical ports for each slot are numbered sequentially starting from zero.
Logical Interfaces Port-channel or Link Aggregation Group (LAG) interfaces are logical interfaces
that are only used for bridging functions.
VLAN routing interfaces are only used for routing functions.
Loopback interfaces are logical interfaces that are always up.
Tunnel interfaces are logical point-to-point links that carry encapsulated packets.
CPU ports CPU ports are handled by the driver as one or more physical entities located on
physical slots.
Note: In the CLI, loopback and tunnel interfaces do not use the unit/slot/port format. To
specify a loopback interface, you use the loopback ID. To specify a tunnel
interface, you use the tunnel ID.
ProSafe 7200 Managed Switches CLI Manual, Software Version 8.0.3
Using the Command-Line Interface 1-5
v1.0, May 2010
shutdown configuration command reverses the shutdown of an interface. Use the command
without the keyword no to re-enable a disabled feature or to enable a feature that is disabled by
default. Only the configuration commands are available in the no form.
Managed Switch Modules
Managed switch software consists of flexible modules that can be applied in various combinations
to develop advanced Layer 2/3/4+ products. The commands and command modes available on
your switch depend on the installed modules. Additionally, for some show commands, the output
fields might change based on the modules included in the software.
The software suite includes the following modules:
• Switching (Layer 2)
• Quality of Service
• Management (CLI, Web UI, and SNMP)
• IPv6 Management—Allows management of the device through an IPv6 through an IPv6
address without requiring the IPv6 Routing package in the system. The management address
can be associated with the network port (front-panel switch ports), a routine interface (port or
VLAN) and the Service port.
• Stacking
Not all modules are available for all platforms or software releases.
Command Modes
The CLI groups commands into modes according to the command function. Each of the command
modes supports specific software commands. The commands in one mode are not available until
you switch to that particular mode, with the exception of the User EXEC mode commands. You
can execute the User EXEC mode commands in the Privileged EXEC mode.
The command prompt changes in each command mode to help you identify the current mode.
Table 5 describes the command modes and the prompts visible in that mode.
Note: The command modes available on your switch depend on the software modules
that are installed. For example, a switch that does not support BGPv4 does not have
the Router BGPv4 Command Mode.

Accessing the CLI
You can access the CLI by using a direct console connection or by using a telnet or SSH
connection from a remote management host.
For the initial connection, you must use a direct connection to the console port. You cannot access
the system remotely until the system has an IP address, subnet mask, and default gateway. You can
set the network configuration information manually, or you can configure the system to accept
these settings from a BOOTP or DHCP server on your network. For more information, see
“Network Interface Commands” on page 8-4.

Stacking Commands
The Stacking Commands chapter includes the following sections:
• “Dedicated Port Stacking” on page 2-1
• “Front Panel Stacking Commands” on page 2-10
Dedicated Port Stacking
This section describes the commands you use to configure dedicated port stacking.
stack
This command sets the mode to Stack Global Config.
Note: The commands in this chapter are in one of two functional groups:
Note: Show commands display switch settings, statistics, and other information.
Note: Configuration commands configure features and options of the switch. For
every configuration command, there is a show command that displays the
configuration setting.
The Primary Management Unit is the unit that controls the stack.

Stacking Commands 2-2
v1.0, May 2010
member
This command configures a switch. The <unit> is the switch identifier of the switch to be
added/removed from the stack. The <switchindex> is the index into the database of the
supported switch types, indicating the type of the switch being preconfigured. The switch index is
a 32-bit integer. This command is executed on the Primary Management Unit.
no member
This command removes a switch from the stack. The <unit> is the switch identifier of the
switch to be removed from the stack. This command is executed on the Primary Management Unit.
switch priority
This command configures the ability of a switch to become the Primary Management Unit. The
<unit> is the switch identifier. The <value> is the preference parameter that allows the user
to specify, priority of one backup switch over another. The range for priority is 1 to 15. The switch
with the highest priority value will be chosen to become the Primary Management Unit if the
active Primary Management Unit fails. The switch priority defaults to the hardware management
preference value 1. Switches that do not have the hardware capability to become the Primary
Management Unit are not eligible for management.
Format member <unit> <switchindex>
Mode Stack Global Config
Note: Switch index can be obtained by executing the show supported switchtype
command in User EXEC mode.
Format no member <unit>
Mode Stack Global Config
Default enabled
Format switch <unit> priority <value>

Stacking Commands 2-3
v1.0, May 2010
switch renumber
This command changes the switch identifier for a switch in the stack. The <oldunit> is the
current switch identifier on the switch whose identifier is to be changed. The <newunit> is the
updated value of the switch identifier. Upon execution, the switch will be configured with the
configuration information for the new switch, if any. The old switch configuration information will
be retained, however the old switch will be operationally unplugged. This command is executed on
the Primary Management Unit.
movemanagement
This command moves the Primary Management Unit functionality from one switch to another.
The <fromunit> is the switch identifier on the current Primary Management Unit. The
<tounit> is the switch identifier on the new Primary Management Unit. Upon execution, the
entire stack (including all interfaces in the stack) is unconfigured and reconfigured with the
configuration on the new Primary Management Unit. After the reload is complete, all stack
management capability must be performed on the new Primary Management Unit. To preserve the
current configuration across a stack move, execute the copy system:running-config
nvram:startup-config (in Privileged EXEC) command before performing the stack move.
A stack move causes all routes and layer 2 addresses to be lost. This command is executed on the
Primary Management Unit. The system prompts you to confirm the management move.
Note: If the management unit is renumbered, then the running configuration is no longer
applied (i.e. the stack acts as if the configuration had been cleared)
Format switch <oldunit> renumber <newunit>
Mode Global Config

slot
This command configures a slot in the system. The <unit/slot> is the slot identifier of the
slot. The <cardindex> is the index into the database of the supported card types, indicating the
type of the card being preconfigured in the specified slot. The card index is a 32-bit integer. If a
card is currently present in the slot that is unconfigured, the configured information will be deleted
and the slot will be re-configured with default information for the card.
no slot
This command removes configured information from an existing slot in the system.
set slot disable
This command configures the administrative mode of the slot(s). If you specify [all], the
command is applied to all slots, otherwise the command is applied to the slot identified by
<unit/slot>.
Format slot <unit/slot> <cardindex>
Mode Global Config
Note: Card index can be obtained by executing show supported cardtype command in
User EXEC mode.
Format no slot <unit/slot> <cardindex>
Mode Global Config
Note: Card index can be obtained by executing show supported cardtype command in
User EXEC mode.
