Monitoring Interface and Controller Status

The Cisco IOS software for the Catalyst 4500 series switch contains commands that you can enter at the
EXEC prompt to display information about the interface, including the version of the software and the
hardware, the controller status, and statistics about the interfaces. The following table lists some of the
interface monitoring commands. (You can display the full list of show commands by entering the show ?
command at the EXEC prompt.)
To display information about the interface, enter one of the following commands:
Command
Switch# show interfaces [type
slot/interface]
Switch# show running-config
Switch# show protocols [type
slot/interface]
Switch# show version
This example shows how to display the status of Fast Ethernet interface 5/5:
Switch# show protocols fastethernet 5/5
FastEthernet5/5 is up, line protocol is up
