Monitoring and Maintaining the Interfaces
These sections contain interface monitoring and maintenance information:

Monitoring Interface Status

Commands entered at the privileged EXEC prompt display information about the interface, including
the versions of the software and the hardware, the configuration, and statistics about the interfaces.
Table 12-4 lists some of these interface monitoring commands. (You can display the full list of show
commands by using the show ? command at the privileged EXEC prompt.) These commands are fully
described in the Cisco IOS Interface Command Reference, Release 12.2 from the Cisco.com page under
Documentation > Cisco IOS Software > 12.2 Mainline > Command References.
