abort
To terminate a configuration session and discard all uncommitted changes without system confirmations, use the abort command in any configuration mode.
Command History
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 abort command to terminate a configuration session and return to EXEC mode from any configuration mode. This command causes all uncommitted configuration changes to be discarded. You will not be prompted to commit the changes.
Task ID
Task ID
Operations
Task ID for the feature or mode impacted by the command

Examples
The following example shows how to use the abort command to discard all changes made during a configuration session:
RP/0/0/CPU0:router# configure RP/0/0/CPU0:router(config)# interface gigabitethernet 0/2/0/0 RP/0/0/CPU0:router(config-if)# ipv4 address 1.1.1.1 255.0.0.0 RP/0/0/CPU0:router(config-if)# abort RP/0/0/CPU0:router#admin
Command History
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 admin command to enter administration EXEC mode. Administration commands are used to configure secure domain routers (SDRs) and to execute various administration plane commands.
Note
Administration commands can be run only by entering administration mode and not by prefixing the admin command with the keyword in EXEC mode.
Task ID
Examples
The following example shows how to enter administration EXEC mode:
RP/0/0/CPU0:router# admin RP/0/0/CPU0:router(admin)#To use administration configuration mode, use the configure command in administration EXEC mode:
RP/0/0/CPU0:router# admin RP/0/0/CPU0:router(admin)# configure RP/0/0/CPU0:router(admin-config)#alias
To create a command alias, use the alias command in global configuration mode. To delete an alias, use the no form of this command.
Syntax Description
alias-name
Name of the command alias. Alias names can be a single word or multiple words joined by a hyphen (-) or an underscore (_).
param-list
(Optional) Parameters assigned to the alias. These parameters are filled in at execution time.
content
Original command syntax. Valid abbreviations of the original command syntax can be entered for the content argument.
Command History
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.
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 routerUse the show aliases command to display all command aliases or the command aliases in a specified mode.
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/0/0/CPU0:router# configure RP/0/0/CPU0:router(config)# alias ipbr show ipv4 interface brief RP/0/0/CPU0:router(config)# show configuration Building configuration... alias ipbr show ipv4 interface brief end RP/0/0/CPU0:router(config)# commit RP/0/0/CPU0:Feb 21 04:42:57.017 : config[65689]: %MGBL-LIBTARCFG-6-COMMIT : Configuration committed by user 'lab'.

RP/0/0/CPU0:router(exec)# shint_both(gigabitethernet1/2/3/4)Two commands are issued, as follows:
RP/0/0/CPU0:router(exec)# show interface gigabitethernet1/2/3/4; show run interface gigabitethernet1/2/3/4apply-template
To apply a template to the target configuration, use the apply-template command in global configuration mode.
Syntax Description
template-name
Name of the template to be applied to the running configuration. Use the template command to define a template.
param-list
(Optional) Up to five template parameters.
Command History
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 apply-template command to apply a template to the target configuration. Templates allow you to create a template name that represents a group of configuration commands.
Use the template command to define a template. Use the end-template command to exit template configuration mode and return to global configuration mode. Use the show-running command with the optional template template-name keyword and argument to display the contents of a template.
Task ID
Examples
The following example shows how to define a template and then apply the template to the target configuration:
RP/0/0/CPU0:router(config)# template hostname-template RP/0/0/CPU0:router(config-TPL)# hostname router1 RP/0/0/CPU0:router(config-TPL)# end-template RP/0/0/CPU0:router(config)# apply-template hostname-templateclear comment
To discard a comment associated with a configuration, use the clear comment command in any configuration mode.
Command History
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 clear comment command clears any comments that were added for a specific configuration in the configuration file. After you enter the clear comment command, enter the configuration for which you want to delete the comment on a separate line.
To enter configuration comments, enter ! followed by the comment. The comment you enter is associated with the next configuration entered. For example:
RP/0/0/CPU0:router#!router1 is located in xxx RP/0/0/CPU0:router# hostname router1 RP/0/0/CPU0:router# commitThe comment is displayed in the output of the show running-config command:
RP/0/0/CPU0:router# show running-config ... !router1 is located in xxx hostname router1 ...Task ID
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.
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 History
Release
Modification
Release 3.2
This command was introduced.
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
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/0/0/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] yclear 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.
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 History
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 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/0/0/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/0/0/CPU0:router(config)# hostname router2 RP/0/0/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.
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
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/0/0/CPU0:router# admin RP/0/0/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.
RP/0/0/CPU0:router# clear configuration inconsistency 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 Updating Commit Database. Please wait...[OK]In the following example, a history of the inconsistency alarms set and cleared for the SDR configuration are displayed using the show configuration history command with the alarm keyword:
RP/0/0/CPU0:router# show configuration history alarm Sno.

To resolve configuration inconsistencies on a replica node, use the clear configuration inconsistency replica command in EXEC or administration EXEC mode.
Syntax Description
location node-id
Resolves the configuration inconsistencies on the designated node. The node-id argument is expressed in the rack/slot/module notation.
Command Default
Administration EXEC mode: Resolves any configuration inconsistencies for the admin plane configuration.
EXEC mode: Resolves any configuration inconsistencies for the SDR configuration.
Command History
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) 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.
Examples
The following example shows how to clear any configuration inconsistencies for the DSC configuration by using the clear configuration inconsistency replica command in EXEC mode:
RP/0/0/CPU0:router# clear configuration inconsistency replica location 0/rp1/cpu0 The replica has been repaired.clear configuration sessions
To clear (end) an active configuration session, use the clear configuration sessions command in EXEC or administration EXEC mode.
Syntax Description
Command History
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 sessions command to clear a configuration session. This command can be used to end the configuration sessions of another user. Any uncommitted changes to a user’s target configuration are discarded.
Use the show configuration sessions command to identify active configuration sessions.
When a configuration session is cleared, a message is displayed on the terminal of the terminated user. For example:
RP/0/0/CPU0:router(config)# This configuration session was terminated by user 'user_a' from line 'aux0_0_CPU0'Task ID
Examples
The following example shows how to clear an active configuration session. In this example, the show configuration sessions command displays the active configuration session. The clear configuration sessions command clears the active configuration session.
RP/0/0/CPU0:router# show configuration sessions Current Configuration Session Line User Date Lock 00000211-002c409b-00000000 con0_RPs1_CPU0 UNKNOWN Mon Feb 2 01:02:09 2009 RP/0/0/CPU0:router# clear configuration sessions 00000211-002c409b-00000000 session ID '00000211-002cb09b-00000000' terminatedcommit
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 History
Release
Modification
Release 3.2
This command was introduced.
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.

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

Use the end command to exit any configuration mode and return directly to EXEC or administration EXEC mode. If you enter this command without committing the changes to the target configuration, you are prompted to do so:
Uncommitted changes found, commit them before exiting(yes/no/cancel)?[cancel]:
- Entering yes saves configuration changes to the running configuration file, exits the configuration session, and returns the router to EXEC or administration EXEC mode.
If errors are found in the running configuration, the configuration session does not end. To view the errors, enter the show configuration (config) command with the failed keyword.
- Entering no exits the configuration session and returns the router to EXEC or administration EXEC mode without committing the configuration changes.
- Entering cancel leaves the router in the current configuration session without exiting or committing the configuration changes.
Note
Entering Ctrl-Z is functionally equivalent to entering the end command.
Use the abort command to exit the configuration session and return to EXEC or administration EXEC mode without being prompted to commit changes and without saving changes to the target configuration.
Examples
The following example shows how to use the end command to end a configuration session. Changes stored in the target configuration are committed by answering yes.
RP/0/0/CPU0:router# configure RP/0/0/CPU0:router(config)# interface gigabitethernet 0/2/0/0 RP/0/0/CPU0:router(config-if)# ipv4 address 1.1.1.1 255.0.0.0 RP/0/0/CPU0:router(config-if)# end Uncommitted changes found, commit them before exiting(yes/no/cancel)?

Table 1 Filtering OptionsCommand
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.
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.

Command History
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 History
Release
Modification
Release 3.2
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.
Examples
Rolling Back to a Specific Commit IDThe following example shows how to roll back to a specific commit ID. In this example, the show configuration commit list command displays the available rollback points. The configuration is then rolled back to a prior commit with the rollback configuration command.

set default-afi
To set the default address family identifier (AFI) for the current session, use the set default-afi command in EXEC mode.
Syntax Description
all
Sets the default AFI to IPv4 and IPv6 for the current session.
ipv4
Sets the default AFI to IPv4 for the current session. This is the default setting.
ipv6
Sets the default AFI to IPv6 for the current session.
Command History
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 command to set the default AFI for the current session. This command acts as a keystroke shortcut for show commands. If the default AFI setting is set to IPv4, then you would not have to specify the ipv4 keyword for show commands that support the ipv4 keyword. For example, if the AFI setting is set to IPv4, you could issue the show route command without specifying the ipv4 keyword to display IPv4 routes in the Routing Information Base (RIB).
Use the show default-afi-safi-vrf command to display the default AFI setting.
Examples
The following example shows how to set the default AFI to IPv6:
RP/0/0/CPU0:router# set default-afi ipv6 %% Default Address Family Identifier is set to 'ipv6'set default-safi
To set the default subaddress family identifier (SAFI) for the current session, use the set default-safi command in EXEC mode.
Syntax Description
all
Sets the default SAFI to multicast and unicast for the current session.
multicast
Sets the default SAFI to multicast for the current session.
unicast
Sets the default SAFI to unicast for the current session. This is the default setting.
Command History
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 command to set the default SAFI setting for the current session. This command acts as a keystroke shortcut for show commands. If the default SAFI setting is set to unicast, you would not have to specify the unicast keyword for show commands that support that keyword. For example, if the default SAFI setting is set to unicast, you could issue the show router command without specifying the unicast keyword to display information about unicast address prefixes in the Routing Information Base (RIB).
Use the show default-afi-safi-vrf command to display the default SAFI setting.
Examples
The following example shows how to set the default SAFI to multicast:
RP/0/0/CPU0:router# set default-safi multicast %% Default Sub-Address Family Identifier is set to 'multicast'set default-vrf
To set the default VPN routing and forwarding (VRF) instance for the current session, use the set default-vrf command in EXEC mode.
Syntax Description
name
Default VPN routing and forwarding name.
none
Sets the default VPN routing and forwarding name to empty.
Command History
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.
Examples
In the following example, the default VRF is set to “dft_vrf:”
RP/0/0/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/0/0/CPU0:router# show route ipv4 % No matching vrf foundWhen 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/0/0/CPU0:router# set default-vrf none %% Default Virtual Routing/Forwarding is set to '' RP/0/0/CPU0:router# show route ipv4 Codes: C - connected, S - static, R - RIP, M - mobile, B - BGP D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2 E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP i - ISIS, L1 - IS-IS level-1, L2 - IS-IS level-2 ia - IS-IS inter area, su - IS-IS summary null, * - candidate default U - per-user static route, o - ODR, L - local Gateway of last resort is 12.29.0.1 to network 0.0.0.0 S* 0.0.0.0/0 [1/0] via 12.29.0.1, 00:31:30 L 10.10.10.10/32 is directly connected, 3d02h, Loopback1 C 12.29.0.0/16 is directly connected, 00:31:30, MgmtEth0/0/CPU0/0 L 12.29.56.21/32 is directly connected, 00:31:30, MgmtEth0/0/CPU0/0show

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.
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
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/0/0/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 protocolOn 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/0/0/CPU0:router# show configuration running | begin line Building configuration... line console exec-timeout 120 120 ! logging trap --More-- /ipv4 filtering... route ipv4 0.0.0.0 255.255.0.0 pos0/2/0/0 interface TenGigE0/2/0/0 ipv4 address 172.19.73.215 255.255.0.0 endshow aliases

The show history command displays a history of the command entered for the current command mode. For example, enter the show history command to display a history of commands entered in EXEC mode. Enter the show history command in global configuration mode to display a history of the commands entered in global configuration mode.
Task ID
Examples
In the following example, the show history command is run in EXEC mode to display a history of the command entered in EXEC mode:
RP/0/0/CPU0:router# show history configure admin show historyIn the following example, the show history command is run in global configuration mode to display a history of the command entered in global configuration mode:
RP/0/0/CPU0:router(config)# show history interface pos 0/1/0/0 ipv4 address 10.0.0.0 root end describe line default autocommand config line default autocommand configure end show historyshow running-config
To display the contents of the currently running configuration or a subset of that configuration, use the show running-config command in the appropriate mode.
Syntax Description
exclude
(Optional) Excludes a specific configuration from the display.
command
(Optional) Displays only a single command or a subset of commands available under a specified command mode.
sanitized
(Optional) Displays a sanitized configuration for safe distribution and analysis.
Command Default
The command without any arguments or keywords displays the entire contents of the running configuration file.
Command History
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.
You can display either the entire running configuration or a subset of the running configuration. The subset may be all the commands within a specified command mode.
Note
In Cisco IOS XR software, the running configuration is automatically used at system startup, reset, or power cycle. The running configuration is the committed configuration.
Use the command with the sanitized keyword to display the contents of the active running configuration without installation-specific parameters. Some configuration details, such as IP addresses, are replaced with different addresses. The sanitized configuration can be used to share a configuration without exposing the configuration details.
When the command is entered in administration configuration mode, the configuration for the administration plane is displayed, including the configured logical routers for the system. When the command is entered in any global configuration mode, or in EXEC mode, the configuration for the specific secure domain router (SDR) is displayed.
Use the exclude keyword followed by a command argument to exclude a specific configuration from the display.
Examples
The following example shows how to enter the command with the question mark (?) online help function to display the available subsets of the running configuration that can be entered to display a subset of the running configuration:

To create a template name and enter template configuration mode, use the template command in global configuration mode. To remove a template definition, use the no form of this command.
Syntax Description
Command History
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 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.
Task ID
Examples
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/0/0/CPU0:router# configure RP/0/0/CPU0:router(config)# template pre-pos RP/0/0/CPU0:router(config-TPL)# interface preconfigure pos0/1/0/0 RP/0/0/CPU0:router(config-if-pre)# ipv4 address 10.3.32.154 255.0.0.0 RP/0/0/CPU0:router(config-if-pre)# end-template RP/0/0/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/0/0/CPU0:router# show running-config template pre-pos template pre-pos interface preconfigure POS0/1/0/0 ipv4 address 10.3.32.154 255.0.0.0 ! end-template
