Note
counters retrieved using SNMP.

Resetting an Interface

To reset an interface, perform this task:
Command
Router# clear interface type
1. type = ethernet, fastethernet, gigabitethernet, or tengigabitethernet
This example shows how to reset Fast Ethernet port 5/5:
Router# clear interface fastethernet 5/5
Router#

Shutting Down and Restarting an Interface

You can shut down an interface, which disables all functions on the specified interface and shows the
interface as unavailable on all monitoring command displays. This information is communicated to other
network servers through all dynamic routing protocols. The interface is not included in any routing
updates.
To shut down an interface and then restart it, perform this task:
Command
Step 1
Router(config)# interface {{vlan vlan_ID} |
1
{type slot/port} | {port-channel channel_ID}}
Step 2
Router(config-if)# shutdown
Step 3
Router(config-if)# no shutdown
1. type = ethernet, fastethernet, gigabitethernet, or tengigabitethernet
This example shows how to shut down Fast Ethernet port 5/5:
Router(config)# interface fastethernet 5/5
Router(config-if)# shutdown
Router(config-if)#
*Sep 30 08:33:47: %LINK-5-CHANGED: Interface FastEthernet5/5, changed state to
administratively down
This example shows how to reenable Fast Ethernet port 5/5:
Router(config-if)# no shutdown
Router(config-if)#
*Sep 30 08:36:00: %LINK-3-UPDOWN: Interface FastEthernet5/5, changed state to up
To check if an interface is disabled, enter the EXEC show interfaces command. An interface that has
been shut down is shown as administratively down in the show interfaces command display.
