Chapter 1
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
• “Unit/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]
1-1
Managed Switch CLI Manual, Release 8.0
• 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}
| Vertical bars choice1 | choice2 Separates the mutually exclusive choices. [{}] Braces within
square brackets
[{choice1 | choice2}]
Using the Command-Line Interface 1-2
Indicates that you must select a parameter from the list of choices.
Indicates a choice within an optional element.
Managed Switch CLI Manual, Release 8.0

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.
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
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.
with Spaces”. An empty string (“”) is not valid.

Unit/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.
Using the Command-Line Interface 1-3
Managed Switch CLI Manual, Release 8.0
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.
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.
The port identifies the specific physical port or logical interface being managed on a given slot.
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.

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
Using the Command-Line Interface 1-4
Managed Switch CLI Manual, Release 8.0
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)
• Routing (Layer 3)
• IPv6—IPv6 routing
• Multicast
• 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.
Using the Command-Line Interface 1-5
Managed Switch CLI Manual, Release 8.0
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 10-4.

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
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.
Chapter 2

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.
Format stack Mode Global Config
2-1
Managed Switch CLI Manual, Release 8.0
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.
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.
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.
Format no member <unit> Mode Stack Global Config
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.
Default enabled Format switch <unit> priority <value> Mode Global Config
Stacking Commands 2-2
Managed Switch CLI Manual, Release 8.0
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.
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
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.
Format movemanagement <fromunit> <tounit> Mode Stack Global Config
Stacking Commands 2-3
Managed Switch CLI Manual, Release 8.0
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.
Format slot <unit/slot> <cardindex> Mode Global Config
Note: Card index can be obtained by executing show supported cardtype command in
User EXEC mode.
no slot
This command removes configured information from an existing slot in the system.
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.
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>.
Stacking Commands 2-4
Managed Switch CLI Manual, Release 8.0
If a card or other module is present in the slot, this administrative mode will effectively be applied to the contents of the slot. If the slot is empty, this administrative mode will be applied to any module that is inserted into the slot. If a card is disabled, all the ports on the device are operationally disabled and shown as “unplugged” on management screens.
Format set slot disable [<unit/slot> | all] Mode Global Config
no set slot disable
This command unconfigures the administrative mode of the slot(s). If you specify [all], the command removes the configuration from all slots, otherwise the configuration is removed from the slot identified by <unit/slot>.
If a card or other module is present in the slot, this administrative mode removes the configuration from the contents of the slot. If the slot is empty, this administrative mode removes the configuration from any module inserted into the slot. If a card is disabled, all the ports on the device are operationally disabled and shown as “unplugged” on management screens.
Format no set slot disable [<unit/slot> | all] Mode Global Config
set slot power
This command configures the power mode of the slot(s) and allows power to be supplied to a card located in the slot. If you specify [all], the command is applied to all slots, otherwise the command is applied to the slot identified by <unit/slot>.
Use this command when installing or removing cards. If a card or other module is present in this slot, the power mode is applied to the contents of the slot. If the slot is empty, the power mode is applied to any card inserted into the slot.
Format set slot power [<unit/slot> | all] Mode Global Config
Stacking Commands 2-5
Managed Switch CLI Manual, Release 8.0
no set slot power
This command unconfigures the power mode of the slot(s) and prohibits power from being supplied to a card located in the slot. If you specify [all], the command prohibits power to all slots, otherwise the command prohibits power to the slot identified by <unit/slot>.
Use this command when installing or removing cards. If a card or other module is present in this slot, power is prohibited to the contents of the slot. If the slot is empty, power is prohibited to any card inserted into the slot.
Format no set slot power [<unit/slot> | all] Mode Global Config
reload (Stack)
This command resets the entire stack or the identified <unit>. The <unit> is the switch identifier. The system prompts you to confirm that you want to reset the switch.
Format reload [<unit>] Mode User EXEC
show slot
This command displays information about all the slots in the system or for a specific slot.
Format show slot [<unit/slot>] Mode User EXEC
