Shutting Down and Restarting the Interface
Shutting down an interface disables all functions on the specified interface and marks the interface as
unavailable on all monitoring command displays.
Beginning in privileged EXEC mode, follow these steps to shut down an interface:
Command
Step 1
configure terminal
Step 2
interface {vlan vlan-id} | {{fastethernet | gigabitethernet}
interface-id} | {port-channel port-channel-number}
Step 3
shutdown
Step 4
end
Step 5
show running-config
Use the no shutdown interface configuration command to restart the interface.
This example shows how to shut down Fast Ethernet interface 0/5:
Switch# configure terminal
Switch(config)# interface fastethernet0/5
Switch(config-if)# shutdown
Switch(config-if)#
