• unit—Must match a port number on the selected interface.
• accounting—(Optional) Displays the number of packets of each protocol type that have been sent through the interface.
• slot—Refer to the appropriate hardware manual for slot and port information.
• port—Refer to the appropriate hardware manual for slot and port information.

This command first appeared in Cisco IOS Release 10.0. If you do not provide values for the argument unit (or slot and port on the Cisco 7200 series or slot and port-adapter on the Cisco 7500 series), the command will display statistics for all network interfaces. The optional keyword accounting displays the number of packets of each protocol type that have been sent through the interface.
