Show code for specific block in cisco IOS conf mode?

  • 772

I work with Fortigate gear a lot and in the CLI it's possible to navigate to a node (say config system global then type in show and it will show me the configuration from that block.

In IOS I can't figure out how to do this, I know I can exit conf term mode and use show run but the configs can be very long.

Is it possible while in say:

router>en
router#conf t
router(config)#interf f0/1

To type a command that will show me only the config section like this:

interface FastEthernet0/1
 no ip address
 speed auto
 full-duplex
 pppoe enable group global
 pppoe-client dial-pool-number 1

Thanks for any advice!

    I think what you are looking for is :

    router# show running-config interface FastEthernet0/1

    This will only display the configuration for port Fa0/1.

    When you are in config mode, you can use the do keyword to call the show command :

    router(config)# do show running-config interface FastEthernet0/1

  2. Try

    show running-config | section ?

    e.g.

    show running-config | section router bgp

    It works similar to the include statement, but also lists all the sub-commands.

  3. Another useful tool is the pipe command | and include, so:

    router# show running-config | include interface

    would show you all lines in the running-config containing the word interface
