Troubleshooting Ethernet 4-61
show interfaces ethernet
show interfaces ethernet unit [accounting]
show interfaces ethernet [slot | port] [accounting] (for the Cisco 7200 series and Cisco 7500)
show interfaces ethernet [type slot | port-adapter | port] (for ports on VIP cards in the
Cisco 7500 series routers)
Syntax Description
• 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.
• port-adapter—Refer to the appropriate hardware manual for information about port adapter
compatibility.
Command Mode
Privileged exec
Usage Guidelines
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.
