Monitoring Interface Status; Clearing Counters On An Interface - Cisco WS-SUP32-GE-3B - Supervisor Engine 32 Software Configuration Manual

Chapter 7 Configuring Interfaces

Monitoring Interface Status

The software 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 and statistics about interfaces. The
following table lists some of the interface monitoring commands. (You can display the complete list of
show commands by using the show ? command at the EXEC prompt.) These commands are described
in the Cisco IOS Interface Command Reference publication.
To display information about the interface, perform these tasks:
Command
Router# show ibc
Router# show eobc
Router# show interfaces [type slot/port]
Router# show running-config
Router# show rif
Router# show protocols [type slot/port]
Router# show version
This example shows how to display the status of Fast Ethernet port 5/5:
Router# show protocols fastethernet 5/5
FastEthernet5/5 is up, line protocol is up
Router#

Clearing Counters on an Interface

To clear the interface counters shown with the show interfaces command, perform this task:
Command
Router# clear counters {{vlan vlan_ID} |
1
{type slot/port} | {port-channel channel_ID}}
1. type = ethernet, fastethernet, gigabitethernet, or tengigabitethernet
This example shows how to clear and reset the counters on Fast Ethernet port 5/5:
Router# clear counters fastethernet 5/5
Clear "show interface" counters on this interface [confirm] y
Router#
*Sep 30 08:42:55: %CLEAR-5-COUNTERS: Clear counter on interface FastEthernet5/5
The clear counters command clears all the current counters from the interface unless the optional
arguments specify a specific interface.
