Display Configuration of a Single Interface

Displaying configuration of a single interface can be a time-consuming task if your router has extremely long configuration (for example, high-end device with hundreds of interfaces, route-maps, access-lists etc.). In this case, the interface keyword of the show running-config command becomes extremely useful.

For example, the show running-config interface serial 0/0.1 command displays only configuration of the specified interface (without building the whole running configuration)

POP#show running-config interface serial 0/0.1
Building configuration...

Current configuration : 154 bytes
interface Serial0/0.1 point-to-point

  1. Got any tricks to for example display running config for all vlan interfaces?
    Something like "sh ru int vlan *" ?
