Clearing And Resetting The Interface; Shutting Down And Restarting An Interface - Cisco 4500M Software Manual

Monitoring and Maintaining the Interface
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
Switch#

Clearing and Resetting the Interface

To clear the interface counters shown with the show interfaces command, enter the following command:
Command
Switch# clear counters { type slot/interface }
This example shows how to clear and reset the counters on Fast Ethernet interface 5/5:
Switch# clear counters fastethernet 5/5
Clear "show interface" counters on this interface [confirm] y
Switch#
*Sep 30 08:42:55: %CLEAR-5-COUNTERS: Clear counter on interface FastEthernet5/5
by vty1 (171.69.115.10)
Switch#
The clear counters command (without any arguments) clears all the current interface counters from all
interfaces.
Note The clear counters command does not clear counters retrieved with SNMP; it clears only those counters
displayed with the EXEC show interfaces command.

Shutting Down and Restarting an Interface

You can disable an interface, which disables all functions on the specified interface and marks the
interface as unavailable on all monitoring command displays. This information is communicated to other
network servers through all dynamic routing protocols. The interface will not be mentioned in any
routing updates.
To shut down an interface and then restart it, perform this task:
Command
Step 1
Switch(config)# interface {vlan vlan_ID } |
{{fastethernet | gigabitethernet |
tengigabitethernet} slot / port } | {port-channel
port_channel_number }
Step 2
Switch(config-if)# shutdown
Step 3
Switch(config-if)# no shutdown
