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.

Usage Guidelines

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

Configuration statements in configuration groups come into effect only when the configuration groups are applied in the system configuration, and the configuration statements have the correct context and inheritance priority in the mode in which the configuration groups are applied. The maximum number of configuration groups that can be specified in a single apply-group command is eight.

To change the composition of an apply-group command, you must specify all desired groups. For example, if you used the command apply-group g10 g20 g30, and now you want to add the group g15, use the command apply-group g10 g15 g20 g30. If you now want to delete group g20, use the command apply-group g10 g15 g30. If you use the no apply-group command, all groups are removed from the configuration.

Note	From the Release 6.3.1 onwards, you are able to enter the Flexible CLI config group definition, apply-group and exclude-group command in any order as long as the entire commit has all the group definitions needed.

Note	Use multi-line configuration style to configure Flexible CLI configuration groups by entering each configuration mode in a separate line, one configuration per line. This is important so that the configuration properties are fully inherited and for better readability during troubleshooting.

Usage Guidelines

To use this command, you must be in a user group associated with a task group that includes appropriate task IDs. If the 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

Usage Guidelines

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.

The comment is displayed in the output of the show running-config command:

RP/0/RP0/CPU0:router# show running-config
...
!router1 is located in xxx
hostname router1
...
  

Usage Guidelines

To use this command, you must be in a user group associated with a task group that includes appropriate task IDs. If the 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

Usage Guidelines

To use this command, you must be in a user group associated with a task group that includes appropriate task IDs. If the 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 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.

Usage Guidelines

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

In XR EXEC mode, the replica nodes are the that can become the .

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

Usage Guidelines

To use this command, you must be in a user group associated with a task group that includes appropriate task IDs. If the 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/RP0/CPU0:router(config)# This configuration session was terminated by user 'user_a' from line 'aux0_0_CPU0'

Usage Guidelines

To define a template, use the template command. To apply a template to the target configuration, use the apply-template command. To view the contents of a template, use the show running-config command with the optional template template-name keyword and argument.

Usage Guidelines

Use the end command to exit any configuration mode and return directly to XR EXEC mode System Admin 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 XR EXEC mode System Admin 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 XR EXEC mode System Admin 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 XR EXEC mode System Admin EXEC mode without being prompted to commit changes and without saving changes to the target configuration.

Usage Guidelines

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

To log off from a terminal session, enter the exit command in XR EXEC mode System Admin EXEC mode.

When exiting from global or administration configuration mode to XR EXEC mode System Admin EXEC mode, you are prompted to commit any uncommitted configuration changes.

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 XR EXEC mode System Admin 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 XR EXEC mode System Admin 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 the exit command from global configuration is functionally equivalent to entering the end command.

Usage Guidelines

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

The group command enters group configuration mode where you can list a series of configuration statements that can then be used elsewhere in the router configuration. Most configuration commands can be used in group configuration mode. You must be in a user group associated with a task group that includes the appropriate task IDs for each of the command statements that you list within a configuration group.

The group-name argument is limited to 32 characters and is case-sensitive. It must not contain any of these special characters:

• ` - grave

• ' - single quote

• " - double quote

• < - less than

• > - greater than

• ( - open parenthesis

• ) - close parenthesis

• [ - open bracket

• ] - close bracket

• { - open brace

• } - close brace

• / - slash

• \ - backslash

• & - ampersand

• ? - question mark

• ~ - tilde

• * - asterisk

• % - percent sign

• = - equal sign

• , - comma

• + - plus sign

• | - vertical bar

•   - space

A configuration group can be removed from the running configuration, only if it is not used by a configured apply-group command.

To exit from configuration group submode and return to global configuration mode, use the end-group command.

Regular expressions are used within the configuration statements to make them widely applicable. POSIX 1003.2 regular expressions are supported in the names of configuration statements. Single quotes are used to delimit a regular expression. For example, to specify the regular expression GigabitEthernet.* that matches all GigabitEthernet interfaces, enter the regular expression within single quotes as 'GigabitEthernet.*'.

To display a list of available interface types for your router configuration, enter interface ? at the configuration group prompt:

RP/0/RP0/CPU0:router(config-GRP)# interface ?

  ATM              'RegExp': ATM Network Interface(s)
  BVI              'RegExp': Bridge-Group Virtual Interface
  Bundle-Ether     'RegExp': Aggregated Ethernet interface(s)
  Bundle-POS       'RegExp': Aggregated POS interface(s)
  GigabitEthernet  'RegExp': GigabitEthernet/IEEE 802.3 interface(s)
  IMA              'RegExp': ATM Network Interface(s)
  Loopback         'RegExp': Loopback interface(s)
  MgmtEth          'RegExp': Ethernet/IEEE 802.3 interface(s)
  Multilink        'RegExp': Multilink network interface(s)
  Null             'RegExp': Null interface
  POS              'RegExp': Packet over SONET/SDH network interface(s)
  PW-Ether         'RegExp': PWHE Ethernet Interface
  PW-IW            'RegExp': PWHE VC11 IP Interworking Interface
  Serial           'RegExp': Serial network interface(s)
  tunnel-ip        'RegExp': GRE/IPinIP Tunnel Interface(s)
  tunnel-mte       'RegExp': MPLS Traffic Engineering P2MP Tunnel interface(s)
  tunnel-te        'RegExp': MPLS Traffic Engineering Tunnel interface(s)
  tunnel-tp        'RegExp': MPLS Transport Protocol Tunnel interface
  

Note	Although you are required to enter only enough characters for the interface type to be unique, it is recommended that you enter the entire phrase. All interface types used in regular expressions are case-sensitive.

For example, you can use the command interface 'GigabitEthernet.*', but not interface 'gigabite.*'. To specify a subinterface, prefix the expression with the characters \. (backslash period), for example: interface 'GigabitEthernet.*\..*'. Refer to the Configuring Flexible Command Line Interface Configuration Groups module in the System Management Configuration Guide for Cisco NCS 5500 Series RoutersSystem Management Configuration Guide for Cisco NCS 540 Series RoutersSystem Management Configuration Guide for Cisco NCS 560 Series Routers for more extensive examples.

Usage Guidelines

The hostname is used in prompts and default configuration filenames.

No blank or space characters are permitted as part of a name. Do not expect case to be preserved. Uppercase and lowercase characters look the same to many Internet software applications. It may seem appropriate to capitalize a name the same way you might do in English, but conventions dictate that computer names appear all lowercase. For more information, see RFC 1178, Choosing a Name for Your Computer.

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.
