To reset an interface, perform this task:

This example shows how to reset Fast Ethernet port 5/5:

Router# clear interface fastethernet 5/5 

Router# 

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: 

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)#

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
