Chapter 11      Configuring Interface Characteristics
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:
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.
