General question of how to maintain device configuration

[leowls]

Hi guys,

Is there anyway I can check for all the commands related to a certain configuration on a switch/router? For example for "Policy Based Routing" configuration, is there a way for to list all PBR commands if there is a need to remove them from the device completely? 

Thanks.

Hello,

you can use the | (pipe) command with keywords to filter and display parts of your configuration, e.g.:

R1#sh run | section route-map
route-map BGP_OUT permit 10
match ip address prefix-list BGP_PREFIX
set community no-export

You can also use 'grep' to filter output.

Router#conf t
Router(config)#shell processing full
Router(config)#exit
Router#terminal shell

This enables you to run show commands with grep.

Router#sh run | grep 'route-map'

The | pipe command allows for regular expressions as well...

BTW, older Cisco software images don't support as many line matching commands as the newer Cisco images. For example, you might find "sec(tion)" not supported, but some commands go way back, like "in(clude)".
