Chapter 5 CLI Tips, Techniques, and Shortcuts
Wildcards, Templates, and Aliases
Examples
In the following example, a simple template is defined. The template contents are then displayed with
the show running-config template template-name command:
RP/0/RSP0/CPU0:router# configure
RP/0/RSP0/CPU0:router(config)# template jbtest
RP/0/RSP0/CPU0:router(config-TPL)# hostname test
RP/0/RSP0/CPU0:router(config-TPL)# end-template
RP/0/RSP0/CPU0:router(config)# commit
RP/0/RSP0/CPU0:router(config)# show running-config template jbtest
template jbtest
hostname test
end-template
In the next example, a template is defined, and the template requires a parameter. The template contents
are then displayed with the show running-config template template-name command:
RP/0/RSP0/CPU0:router# configure
RP/0/RSP0/CPU0:router(config)# template test2 (hostname)
RP/0/RSP0/CPU0:router(config-TPL)# hostname $hostname
RP/0/RSP0/CPU0:router(config-TPL)# end-template
RP/0/RSP0/CPU0:router(config)# commit
RP/0/RSP0/CPU0:router(config)# show running-config template test2
template test2 (hostname )
hostname $hostname
end-template
Applying Configuration Templates
To apply a template, type the apply-template template-name [(parameter)] command in global
configuration mode and consider the following guidelines:
• Only one template can by applied at a time.
• If the same template is applied multiple times, the most recent application overwrites the previous
ones.
• Provide the exact number of parameters for the template.
• Templates are applied as a “best effort” operation; only valid changes are committed. If any
command in the template fails, that command is discarded.
• After a template is applied, the show configuration command displays the target configuration
changes. The target configuration must be committed (with the commit command) to become part
of the running configuration.
Examples
In the following example, a simple template is defined. The template contents are then displayed with
the show running-config template template-name command:
RP/0/RSP0/CPU0:router# configure
RP/0/RSP0/CPU0:router(config)# apply-template jbtest
RP/0/RSP0/CPU0:router(config)# show running-config template jbtest
