The clear counters privileged EXEC command does not clear counters retrieved by using Simple 
Network Management Protocol (SNMP), but only those seen with the show interface privileged EXEC 
command.

Shutting down an interface 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 is not mentioned in any routing updates.

Beginning in privileged EXEC mode, follow these steps to shut down an interface:

Use the no shutdown interface configuration command to restart the interface.

To verify that an interface is disabled, enter the show interfaces privileged EXEC command. A disabled 
interface is shown as administratively down in the display.

Enter global configuration mode.

interface {vlan vlan-id} | {{fastethernet | gigabitethernet} 
interface-id} | {port-channel port-channel-number}

Select the interface to be configured.

Shut down an interface.

Return to privileged EXEC mode.

Verify your entry.
