  2. Enable port lock globally:

    portlock enable

  3. Enter GigabitEthernet Interface Configuration mode:

    interface gigabitethernet {slot/port[/sub-port][-slot/port[/sub-port]][,...][slot/all][all]}

  4. Lock a port:

    lock [port {slot/port[/sub-port][-slot/port[/sub-port]][,...][slot/all][all]}] enable

Example

Switch:1> enable 
Switch:1# configure terminal

Log on to GigabitEthernet Interface Configuration mode:

Switch:1(config)# interface GigabitEthernet 1/1

Lock port 1/1:

Switch:1(config-if)# lock port 1/1 enable
