Command
Show Running-Config Interface
Use
Shows the current configuration of a given interface on the router. This command is useful because it reduces IOS’s output to just show you the interface information. Read the filtering page under the show command section for more information on further ways to filter output.
Syntax
Router#show running-config interface <int name>
Example
In this example, we trim the show run output to just show the configuration of Fa0/0 on R2.
R2#show run int fa0/0 Building configuration… Current configuration : 93 bytes ! interface FastEthernet0/0 ip address 10.1.1.2 255.255.255.0 duplex auto speed auto end R2#
