Using show Commands to Display Interface Information
To display information about a specific interface, use the show interfaces command with the
interface type and port address in the format show interfaces [type slot/adapter/port].
Following is a partial-display example of how the show interfaces command displays status
information (including the physical slot and port address) for the interface you specify. In this
example, most of the status information for each interface is omitted, and an FEIP in interface
processor slot 3 is shown:
Router# sh int fastethernet 2/0/0
FastEthernet2/0/0 is administratively down, line protocol is down
(additional displayed text omitted from this example)
With the show interfaces [type slot/adapter/port] command, use arguments such as the interface
type (fastethernet, and so forth) and the port number (slot/port) to display information about a
specific interface only, as in the following example of the show interfaces fastethernet command,
which shows information specific to the first interface on an FEIP in interface processor slot 2:
Router# show interfaces fastethernet 2/0/0
FastEthernet2/0/0 is administratively down, line protocol is down
(additional displayed text omitted from this example)
