RP/0//CPU0:router#

Limiting show Command Output to a Specific Feature or Interface
Entering keywords and arguments in the show command limits the show output to a specific feature or
interface.
In the following example, only information about the static IP route configuration appears:
RP/0//CPU0:router# show running-config router static
router static
address-family ipv4 unicast
0.0.0.0/0 10.21.0.1
0.0.0.0/0 /1/0/1 10.21.0.1
!
!
In the following example, the configuration for a specific interface appears:
RP/0//CPU0:router# show running-config interface 0/1/0/1
interface /1/0/1
ipv4 address 10.21.54.31 255.255.0.0
!
Using Wildcards to Display All Instances of an Interface

If the full path of the file is not specified, the default directory for your account is used. You should
always save your target configuration files to this location.
If the saved output is to be used as a configuration file, the filename should end with the
for easy identification. This suffix is not required, but can help locate target configuration files.

myconfig.cfg
