Cisco IOS XR software supports generic alias definitions for various entities. Any physical or logical entity can have an alias as a reference. For example, an alias can refer to a command, a partial command, a group of commands, a location, or an IP address.

An alias must first be defined. The alias can then be used in command lines in place of the defined entity.

Following is a list of properties for an alias:

An alias can be used anywhere and in any mode.
An alias can have zero, one, or many parameters.
An alias can refer to those parameters with the $ sign.
If an alias refers to more than one command, the commands must be separated by a semicolon (;).
The size of the alias command is limited to 1024 characters.

The alias command can be used anywhere. If the content referenced by the alias is invalid or inappropriate in that context or mode, the system issues a warning message containing the substituted content.

An alias name should not be a subset of the keywords that it represents as alias. Substitution is done only when the entered input match fails completely. For instance, the attempt to define an alias with “config�? as the alias name fails, as shown in the following example:

RP/0/RP0/CPU0:router# (config)# alias config set_host hostname router
RP/0/RP0/CPU0:router# (config)# show configuration

alias set_host hostname router

Use the show aliases command to display all command aliases or the command aliases in a specified mode.

Task ID

Task ID	Operations
logging	read, write

Examples

The following example shows how to create an alias named ipbr for the show ipv4 interface brief command, commit the configuration, enter EXEC mode, and then enter the configured alias:

RP/0/RP0/CPU0:router# configure
RP/0/RP0/CPU0:router(config)# alias ipbr show ipv4 interface brief
RP/0/RP0/CPU0:router(config)# show configuration 
  
Building configuration... 
alias ipbr show ipv4 interface brief 
end
RP/0/RP0/CPU0:router(config)# commit

The following example shows how to define an alias, mycompany-10ge, for POS interface 1/0/2/3 and then how to use that alias to shut down the interface:

RP/0/RP0/CPU0:router(config)# alias mycompany-10ge gigabitethernet1/0/2/3 
RP/0/RP0/CPU0:router(config)# interface mycompany-10ge 
RP/0/RP0/CPU0:router(config-if)# shutdown
RP/0/RP0/CPU0:router(config-if)# exit
RP/0/RP0/CPU0:router(config)#

The following example shows the use of a parameter name in an alias definition:

RP/0/RP0/CPU0:router(config)# alias shint (intname) show interface $intname

The following example shows an alias defined with one parameter and two commands:

RP/0/RP0/CPU0:router(config)# alias shint_both (intname) show interface $intname;show run interface $intname

The following example shows the use of the alias shint_both in EXEC mode:

RP/0/RP0/CPU0:router(exec)# shint_both(gigabitethernet1/2/3/4)

Two commands are issued, as follows:

RP/0/RP0/CPU0:router(exec)# show interface gigabitethernet1/2/3/4; show run interface gigabitethernet1/2/3/4

RP/0/RP0/CPU0:router(config-if)# ipv4 address 1.1.1.1 255.0.0.0

clear configuration commits

To delete old commit IDs from the commit database to free up disk space, use the clear configuration commits command in EXEC or administration EXEC mode.

clear configuration commits { diskspace kilobytes | oldest number-of-commits }

Syntax Description

diskspace kilobytes

Deletes as many commit IDs (beginning with the oldest available commit ID) from the commit database as required to free the number of kilobytes (KB) specified for the kilobytes argument. The range for the number of kilobytes of disk space to free is 1 to 4194304.

Note

The amount of disk space freed may vary depending on the size and number of commits present in the commit database.

oldest number-of-commits

Deletes the number of commit IDs specified for the number-of-commits argument.

Note

Use the online help ( ? ) function to display the range of commit IDs available for deletion.

Command Default

None

Command Modes

EXEC

Administration EXEC

Command History

Release	Modification
Release 2.0	This command was introduced.
Release 3.2	This command was earlier named clear configuration rollback points .
Release 3.3.0	Support was added for administration EXEC mode.

Usage Guidelines

To use this command, you must be in a user group associated with a task group that includes the proper task IDs. If you suspect user group assignment is preventing you from using a command, contact your AAA administrator for assistance.

Use the clear configuration commits command to delete the number of commit IDs available for rollback operations. The most recent 100 commits are retained by the system. As new commit IDs are added, the oldest commit IDs are discarded and are no longer available for rollback operations.

Note

The clear configuration commits command deletes commits from the commit database only. The running configuration, thus, is not changed.

Note

When a commit ID is deleted from the commit database, it is no longer available for rollback and can no longer be used to display commit changes (with the show configuration rollback changes command).

Use the rollback configuration command to roll back the current running configuration to a previous configuration. Use the show configuration rollback changes command to display a list of the commit IDs available for rollback operations or to display the changes that would be made by the rollback configuration command.

Task ID

Task ID	Operations
config-services	execute

Examples

The following example shows how to delete the oldest 16 commit IDs to free up disk space. After entering this command, you will be prompted to confirm the deletion.

RP/0/RP0/CPU0:router# clear configuration commits oldest 16
  
Deleting 16 rollback points '1000000021' to '1000000036'
256 KB of disk space will be freed. Continue with deletion?[confirm] y

clear configuration inconsistency

To clear an inconsistency alarm for an SDR configuration or admin plane configuration, use the clear configuration inconsistency command in EXEC or administration EXEC mode.

clear configuration inconsistency

Syntax Description

This command has no keywords or arguments.

Command Default

Administration EXEC mode: Clears the inconsistency alarms for the admin plane configuration.

EXEC mode: Clears the inconsistency alarms for an SDR configuration.

Command Modes

EXEC

Administration EXEC

Command History

Release	Modification
Release 3.4.0	This command was introduced.

Usage Guidelines

To use this command, you must be in a user group associated with a task group that includes the proper task IDs. If you suspect user group assignment is preventing you from using a command, contact your AAA administrator for assistance.

An inconsistency alarm is set when there is a failure to restore the configuration; this can occur during router startup, or when a line card, modular services card (MSC), or route processor (RP) card is inserted or removed.

If an inconsistency alarm is set, a message similar to the following example is displayed:

RP/0/0/CPU0:May 26 11:58:40.662 : cfgmgr-rp[130]: %MGBL-CONFIGCLI-3 
   BATCH_CONFIG_FAIL : 28 config(s) failed during startup. To view 
   failed config(s) use the command - "show configuration failed startup"
  
RP/0/0/CPU0:May 26 11:58:41.731 : cfgmgr-rp[130]: 
   %MGBL-CONFIG-3-ADMIN_INCONSISTENCY_ALARM : Admin plane configuration
   inconsistency alarm has been raised. Configuration commits will be
   blocked until an ADMIN plane 'clear configuration inconsistency' command
   has been run to synchronize persisted admin plane configuration with 
   running admin configuration.

When the inconsistency alarm is set, all configuration commit operations fail until the alarm is cleared using the clear configuration inconsistency command. This command clears the alarm and removes the failed configuration.

For example, the following configuration commit fails to finish due to an existing inconsistency alarm:

RP/0/RP0/CPU0:router# configure 
  
ADMIN plane running configuration is inconsistent with persistent 
  configuration.
No configuration commits will be allowed until an admin plane 
'clear configuration inconsistency' command is performed.
RP/0/RP0/CPU0:router(config)# hostname router2
RP/0/RP0/CPU0:router(config)#commit
  
ADMIN plane running configuration is inconsistent with persistent 
  configuration.
No configuration commits will be allowed until an admin plane 
'clear configuration inconsistency' command is performed.

Enter the clear configuration inconsistency command to clear the alarm and allow commit operations to continue.

Note

To reapply the failed configuration, you must reapply and recommit the configuration. Use the load configuration failed command with the startup keyword to populate the target configuration with the contents of the previous failed configuration from the startup configuration.

Use the show configuration history command with the alarm keyword to view the inconsistency alarm set and alarm clear events in the configuration history log.

Command Modes

To clear the inconsistency alarms for the admin plane configuration, enter the clear configuration inconsistency command in administration EXEC mode.

To clear the inconsistency alarms for an SDR configuration, enter the clear configuration inconsistency command in EXEC mode for that SDR.

Task ID

Task ID	Operations
config-services	execute

Examples

The following example shows how to clear the inconsistency alarms for the admin plane configuration by entering the clear configuration inconsistency command in administration EXEC mode:

RP/0/RP0/CPU0:router# admin
RP/0/RP0/CPU0:router(admin)# clear configuration inconsistency
  
Creating any missing directories in Configuration File system...OK
Initializing Configuration Version Manager...OK
Syncing ADMIN commit database with running configuration...OK
Re-initializing cache files...OK
Updating Commit Database.  Please wait...[OK]

The following example shows how to clear the inconsistency alarms for an SDR configuration. The command is entered in EXEC mode and impacts only that SDR.

Creating any missing directories in Configuration File system...OK
Initializing Configuration Version Manager...OK
Syncing commit database with running configuration...OK
Re-initializing cache files...OK

Usage Guidelines

To use this command, you must be in a user group associated with a task group that includes the proper task IDs. If you suspect user group assignment is preventing you from using a command, contact your AAA administrator for assistance.

In administration EXEC mode, the replica node for the clear configuration inconsistency replica command is the standby designated system controller (DSC). In EXEC mode, the replica nodes are the route processors (RPs) or distributed route processors (DRPs) that can become the designated secure domain router shelf controller (DSDRSC) .

Use the clear configuration inconsistency replica command if there is a configuration inconsistency between the standby DSC and the current active DSC; or alternatively, if the configuration on any nodes that could become the DSC is not the same as the configuration on the current DSC. To determine if you have a configuration inconsistency, use the show configuration inconsistency replica command.

To clear configuration inconsistencies for the admin plane configuration, enter the clear configuration inconsistency replica command in administration EXEC mode.

To clear configuration inconsistencies for an SDR configuration, enter the clear configuration inconsistency replica command in EXEC mode for that SDR.

commit

To commit the target configuration to the active (running) configuration, use the commit command in any configuration mode.

commit [best-effort] [ comment line ] [ confirmed [ seconds | minutes minutes ] ] [force] [ label line ] [replace] [ save-running filename file_path ]

Syntax Description

best-effort

(Optional) Merges the target configuration with the running configuration and commits only valid changes (best effort). Some configuration changes might fail due to semantic errors.

comment line

(Optional) Assigns a comment to a commit. This text comment is displayed in the commit entry displayed in the output for the show configuration commit list command with the optional detail keyword.

confirmed [seconds | minutes minutes]

(Optional) Commits the configuration on a trial basis for the time specified in seconds or minutes.

Note

The confirmed option is not available in administration configuration mode.

force

(Optional) Forces a commit operation in low-memory conditions.

label line

(Optional) Assigns a meaningful label. This label is displayed (instead of the autogenerated commit ID) in the output for the show configuration commit list .

replace

(Optional) Replaces the entire running configuration with the contents of the target configuration.

save-running filename file_path

(Optional) Saves the running configuration to a specified file.

Command Default

The default behavior is pseudo-atomic, meaning that all changes must succeed for the entire commit operation to succeed. If any errors are found, none of the configuration changes take effect.

Command Modes

Any configuration

Command History

Release	Modification
Release 2.0	This command was introduced.
Release 3.2	The replace keyword was added.
Release 3.3.0	The confirmed minutes keyword and argument were added. The confirmed option is not available in administration configuration mode.
Release 3.7.0	Support was added for the save-running filename file_path keywords and argument in global configuration mode.
Release 3.8.0	Support was added for the save-running filename file_path keywords and argument in administration configuration mode.

Usage Guidelines

To use this command, you must be in a user group associated with a task group that includes the proper task IDs. If you suspect user group assignment is preventing you from using a command, contact your AAA administrator for assistance.

Changes made during a configuration session are inactive until the commit command is entered. By default, the commit operation is pseudo-atomic, meaning that all changes must succeed for the entire commit operation to succeed. If any errors are found, none of the configuration changes takes effect.

To replace the default numeric ID for the commit, use the optional label keyword. This label is displayed (instead of the autogenerated commit ID) in the output for the show configuration commit list command.

Enter an optional comment with the comment keyword to provide additional information about the commit action. This comment is displayed in the output for the show configuration commit list command with the detail keyword.

Use the optional confirmed minutes keyword and argument to commit a configuration on a trial basis for a minimum of 30 seconds and a maximum of 300 seconds (5 minutes). During the trial configuration period, enter the commit command to confirm the configuration. If the commit command is not entered, then the system reverts to the previous configuration when the trial time period expires. The confirmed option is not available in administration configuration mode.

You can use the commit command in conjunction with the load command. Load a new configuration with the load command, and use the commit command with the replace keyword to have the loaded configuration become the active (running) configuration.

Use the optional save-running filename file_path keywords and argument to save the running configuration to a specified file. To configure automatic saving of the configuration file on every commit, use the configuration commit auto-save command. If automatic saving of the configuration file is already enabled, specifying save-running filename file_path with the commit command has no additional effect.

Caution

Saving the running configuration to a file is CPU intensive.

Note

If you use the commit command without previously loading a target configuration, a blank configuration is committed.

configure

To enter global configuration mode or administration configuration mode, use the configure command in EXEC or administration EXEC mode.

configure [ exclusive | terminal ]

Syntax Description

exclusive	(Optional) Locks the router configuration. The system configuration can be made only from the login terminal.
terminal	(Optional) Configures the system from the login terminal. This is the default.

Command Default

If the configure command is entered without a keyword, the system is configured from the login terminal.

Command Modes

EXEC

Command History

Release	Modification
Release 2.0	This command was introduced.

Usage Guidelines

To use this command, you must be in a user group associated with a task group that includes the proper task IDs. If you suspect user group assignment is preventing you from using a command, contact your AAA administrator for assistance.

Configuration modes are used to enter changes to a target configuration session and commit those changes to the running configuration. A router running Cisco IOS XR software contains multiple configurations:

The configuration for a specific secure domain router (SDR). Each SDR has its own configuration that is modified when a user logs into an SDR and enters global configuration mode . This mode is used to configure SDR-specific features such as routing protocols.
The administration configuration for system-wide resources and settings. Some features, such as creating SDRs, can be configured only in administration configuration mode.

Global Configuration Mode

Use the configure command in EXEC mode to enter global configuration mode and create a new target configuration for an SDR. From global configuration mode, you can enter any configuration mode. Configuration changes entered in global configuration mode impact the SDR to which the user is currently logged in.

Administration Configuration Mode

Use the configure command in administration EXEC mode to enter administration configuration mode and create a new target configuration. From administration configuration mode, you can enter any administration configuration mode. Configuration changes entered in administration configuration mode can impact resources for the entire router. See the command reference documentation for a specific command to determine the impact of commands entered in administration configuration mode.

Router Prompt

After you enter the configure command, the system appends “(config)” to the router prompt, indicating that the router is in a configuration mode. For example:

The following prompt indicates that you are in global configuration mode for an SDR: RP/0/RP0/CPU0:router(config)#
The following prompt indicates that you are in administration configuration mode: RP/0/RP0/CPU0:router(admin-config)#

Locking a Configuration Session

To lock the configuration so that no other user can commit changes to the running configuration during your configuration session, issue the configure command with the exclusive keyword.

Committing Changes and Returning to EXEC or Administration EXEC Mode

Changes to the target configuration remain inactive until the commit command is entered. To leave global configuration or administration configuration mode and return to the EXEC or administration EXEC prompt, issue the end or exit command; you are prompted to commit any uncommitted changes.

To leave configuration mode and return directly to EXEC or administration EXEC mode without being prompted to commit changes and without saving changes to the target configuration, enter the abort command in any configuration mode.

Examples

The following example shows how to enter global configuration mode from EXEC mode and then enter interface configuration mode to configure an IPv4 address for Gigabit Ethernet interface 0/1/0/0. In the example, the configure command commits the configuration, and the end command terminates the configuration session and return the router to EXEC mode.

RP/0/RP0/CPU0:router# configure
RP/0/RP0/CPU0:router(config)# interface gigabitethernet 0/1/0/0
RP/0/RP0/CPU0:router(config-if)# ipv4 address 1.1.1.1 255.0.0.0
RP/0/RP0/CPU0:router(config-if)# commit
RP/0/RP0/CPU0:router(config-if)# end
RP/0/RP0/CPU0:router#

The following example shows how to enter administration configuration mode and then configure an SDR. In this example, the user also enters SDR configuration mode.


RP/0/RP0/CPU0:router# admin 
RP/0/RP0/CPU0:router(admin)# configure
RP/0/RP0/CPU0:router(admin-config)# sdr rname

Usage Guidelines

To use this command, you must be in a user group associated with a task group that includes the proper task IDs. If you suspect user group assignment is preventing you from using a command, contact your AAA administrator for assistance.

Use the more command to display any text file, especially an ASCII file stored on the router or accessible through the network. The file can be a configuration file or any other text file.

Filtering Output

This table shows filter options for the output displayed by the more command.

Table 1 Filtering Options
Command	Purpose
more filesystem: \| begin regular-expression	Begins unfiltered output of the more command with the first line that contains the regular expression.
more filesystem: \| exclude regular-expression	Displays output lines that do not contain the regular expression.
more filesystem: \| include regular-expression	Displays output lines that contain the regular expression.

Adding a Filter at the --More-- Prompt

You can also specify a filter at the --More-- prompt of a more command output. To filter output from the --More-- prompt, enter a forward slash ( / ) followed by a regular expression. The filter remains active until the command output finishes or is interrupted (using Ctrl-Z or Ctrl-C).

A second filter cannot be specified at a --More-- prompt if a filter has already been specified at the original command or at a previous --More-- prompt.
The minus sign (–) preceding a regular expression displays output lines that do not contain the regular expression.
The plus sign (+) preceding a regular expression displays output lines that contain the regular expression.

Note

After you specify a filter for a more command, you cannot specify another filter at the next --More-- prompt. The first specified filter remains until the more begin command output finishes or until you interrupt the output. The use of the keyword does not constitute a filter.

Release	Modification
Release 3.5.0	This command was introduced.

Usage Guidelines

To use this command, you must be in a user group associated with a task group that includes the proper task IDs. If you suspect user group assignment is preventing you from using a command, contact your AAA administrator for assistance.

Examples

The following example shows how to use the pwd command from an interface configuration submode:

RP/0/RP0/CPU0:router# configure 
RP/0/RP0/CPU0:router(config)# interface tengige 0/6/4/5
RP/0/RP0/CPU0:router(config-if)# pwd
  
interface TenGigE0/6/4/5
RP/0/RP0/CPU0:router(config-if)#

rollback configuration

To roll back the running configuration to a previous configuration, use the rollback configuration command in EXEC or administration EXEC mode.

rollback configuration { last number-of-commits | to commit-id } { best-effort | force } [ label label ] comment comment

Syntax Description

last number-of-commits	Rolls back to the configuration that existed before the last number of commits (specified with the number-of-commits argument) were made.
to commit-id	Rolls back to the running configuration that existed before the configuration specified with the commit-id argument.
best-effort	Rolls back to the configuration that existed before the last n commits, and commits only valid changes (best effort). Some configuration changes might fail due to semantic errors.
force	(Optional) Specifies to override any commit blocks.
label label	(Optional) Assigns a text label to this rollback. The label argument must begin with a letter.
comment comment	(Optional) Assigns a text comment to this rollback. The comment argument can be up to 60 characters long.

Command Default

None

Command Modes

EXEC

Administration EXEC

Command History

Release	Modification
Release 2.0	This command was introduced.
Release 3.5.0	This command was added to administration EXEC mode.
Release 4.0.0	The best-effort keyword was added.

Usage Guidelines

To use this command, you must be in a user group associated with a task group that includes the proper task IDs. If you suspect user group assignment is preventing you from using a command, contact your AAA administrator for assistance.

Each time the commit command is entered, a commit ID is assigned to the new configuration. You can revert the system to the configuration of a previous commit ID with the rollback configuration command:

Use the to keyword to revert to the configuration that existed before the configuration specified with the commit-id argument.
Use the last keyword to revert to the configuration that existed before the last number of configuration commits (specified with the number-of-commits argument) were made.
Use show configuration commit list to display a list of the commit IDs available for rollback operations.

Note

The most recent 100 commits are retained by the system. As new commit IDs are added, the oldest commit IDs are discarded and are no longer available for rollback operations.

Use the force keyword to override commits that would fail otherwise. This is useful in the event of a low-memory condition on the router, to revert to a commit that would remove a configuration that caused the low-memory condition.

Note

The rollback operation may fail if you try to rollback two (or more) commits where the individual commits involve the configuration and removing of the configuration of the same item, and there is a dependency of one item over another in any of the individual commit operations.

Usage Guidelines

To use this command, you must be in a user group associated with a task group that includes the proper task IDs. If you suspect user group assignment is preventing you from using a command, contact your AAA administrator for assistance.

Use the set default-vrf command to set the default VRF setting for the current session. This command acts as a keystroke shortcut for show commands. For example, if the default VRF is configured, you can issue the show route command without specifying the VRF name.

When the default VRF for the session is set to none, then IPv4 routes for the system default VRF are displayed.

Note

To override the default VRF setting, specify the VRF name in the show command.

Use the show default-afi-safi-vrf command to display the default VRF setting.

Task ID

Task ID	Operations

Examples

In the following example, the default VRF is set to “dft_vrf:”

RP/0/RP0/CPU0:router# set default-vrf dft_vrf 
  
  %% Default Virtual Routing/Forwarding is set to 'dft_vrf'

In the following command, the show route command is entered without specifying a VRF name. The results for the "dft_vrf" VRF are displayed because the default VRF was set to “dft_vrf.”

RP/0/RP0/CPU0:router# show route ipv4
   
  % No matching vrf found

When the default VRF for the session is set to none, the system default VRF routes are displayed. In the following example, the default VRF is set to (empty) and the show route command displays the system default VRF information:

RP/0/RP0/CPU0:router# set default-vrf none
  
%% Default Virtual Routing/Forwarding is set to ''

Usage Guidelines

To use this command, you must be in a user group associated with a task group that includes the proper task IDs. If you suspect user group assignment is preventing you from using a command, contact your AAA administrator for assistance.

The show commands display information about the system and its configuration. To display a list of the available show commands, use the question mark (?) online help function.

Filtering Output

Search options for the show command are shown in this table.

Table 2 Show Command Search Options
Command	Purpose
show command \| begin regular-expression	Begins unfiltered output of the show command command with the first line that contains the regular expression.
show command \| exclude regular-expression	Displays output lines that do not contain the regular expression.
show command \| include regular-expression	Displays output lines that contain the regular expression.
show command \| file filesystem:	Writes the output lines that contain the regular expression to the specified file on the specified file system.

Adding a Filter at the --More-- Prompt

You can also specify a filter at the --More-- prompt of a show command output. To filter output from the --More-- prompt, enter a forward slash (/) followed by a regular expression. The filter remains active until the command output finishes or is interrupted (using Ctrl-Z or Ctrl-C).

If a filter is specified at the original command or a previous --More-- prompt, a second filter cannot be applied.
The use of the begin keyword does not constitute a filter.
The minus sign (–) preceding a regular expression displays output lines that do not contain the regular expression.
The plus sign (+) preceding a regular expression displays output lines that contain the regular expression.

Task ID

Task ID	Operations
Task ID for the feature used with the show command	read

For example, the show interfaces command requires read privileges in the interface task ID.

Examples

The following example shows output from the show interface | include protocol command. In this example, the show command command includes only lines in which the regular expression “protocol” appears:

RP/0/RP0/CPU0:router# show interface | include protocol
  
  Null0 is up, line protocol is up
  0 drops for unrecognized upper-level protocol
  TenGigE0/2/0/0 is administratively down, line protocol is administratively down
  0 drops for unrecognized upper-level protocol
  TenGigE0/2/0/1 is administratively down, line protocol is administratively down
  0 drops for unrecognized upper-level protocol
  TenGigE0/2/0/2 is administratively down, line protocol is administratively down
  0 drops for unrecognized upper-level protocol
  TenGigE0/2/0/3 is administratively down, line protocol is administratively down
  0 drops for unrecognized upper-level protocol
  FastEthernet0/RP0/CPU0/0 is administratively down, line protocol is administratively
  down
  FastEthernet0/RP0/CPU0/0 is administratively down, line protocol is administratively
  down
  0 drops for unrecognized upper-level protocol

On most systems, the Ctrl-Z key combination can be entered at any time to interrupt the output and return to EXEC mode. For example, use the show running-config | begin hostname command to start the display of the running configuration file at the line containing the hostname setting, then use Ctrl-Z when you get to the end of the information you are interested in.

The following example shows sample output from the show configuration running | begin line command. The output begins with unfiltered output from the first line that contains the regular expression “line.” In this example, at the --More-- prompt, a new search is specified that begins with output lines that contain the regular expression “ipv4.”

Note

The use of the begin keyword does not constitute a filter.

RP/0/RP0/CPU0:router# show configuration running | begin line
  
  Building configuration...

Usage Guidelines

To use this command, you must be in a user group associated with a task group that includes the proper task IDs. If you suspect user group assignment is preventing you from using a command, contact your AAA administrator for assistance.

Use the template command to enter template configuration mode. From template configuration mode, you can group a subset of configuration commands in a named template. Commonly used sets of configuration commands can be grouped into a named template. Defining a template is similar to creating a C macro function. A template provides modularity and ease of use during user configuration.

Use the end-template command to exit template configuration mode. After defining a template, use the apply-template command to apply the template. Use the show running-config command with the optional template keyword and template-name argument to display the contents of a template.

The following example shows how to enter template configuration mode to create a template. In this example, a template named “pre-pos” is defined for the preconfigured Packet-over-SONET/SDH (POS) interface 0/1/0/1. The end-template command is used to exit from template configuration mode.

RP/0/RP0/CPU0:router# configure
RP/0/RP0/CPU0:router(config)# template pre-pos
RP/0/RP0/CPU0:router(config-TPL)# interface preconfigure pos0/1/0/0
RP/0/RP0/CPU0:router(config-if-pre)# ipv4 address 10.3.32.154 255.0.0.0
RP/0/RP0/CPU0:router(config-if-pre)# end-template
RP/0/RP0/CPU0:router(config)#

Note

After configuring a template, you may want to display the contents of the configured template. To display a template configuration, use the show running-config command with the template name keyword and argument.

The following example shows sample output from the show running-config command with the template name keyword and argument. In this example, the output displays the contents of a template named “pre-pos.”

RP/0/RP0/CPU0:router# show running-config template pre-pos
