Shutting Down And Restarting The Interface - Cisco Catalyst 3750 Software Configuration Manual

Monitoring and Maintaining the Interfaces

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