Cisco IOS Tips: Display Interface The Smart Way

Hello there! If you are new here, you might want to subscribe to the RSS feed for updates on this topic.

Use the following command to dsplay brief summary of interfaces

Router#show ip interface brief
Interface                  IP-Address      OK? Method Status                Protocol
FastEthernet0/0            192.168.1.2     YES manual up                    up
FastEthernet0/1            192.168.10.2    YES manual up                    up
FastEthernet1/0            unassigned      YES unset  up                    down
FastEthernet1/1            unassigned      YES unset  up                    down
FastEthernet1/2            unassigned      YES unset  up                    down
FastEthernet1/3            unassigned      YES unset  up                    down
...

To display only the configured interface, the same command can be used with little modification

Router#show ip interface brief | exclude unassigned
Interface                  IP-Address      OK? Method Status                Protocol
FastEthernet0/0            192.168.1.2     YES manual up                    up
FastEthernet0/1            192.168.10.2    YES manual up                    up
Router#

The above command with “include” keyword can be used to display interfaces which has no ip address assigned to them

Router#show ip interface brief | include unassigned
FastEthernet1/0            unassigned      YES unset  up                    down
FastEthernet1/1            unassigned      YES unset  up                    down
FastEthernet1/2            unassigned      YES unset  up                    down
FastEthernet1/3            unassigned      YES unset  up                    down
...
