Enabling or Disabling an Interface

Context

After modifying parameters of an interface, run the shutdown and undo shutdown commands, or run the restart command to make the modification take effect.

When an interface is not connected to a cable or a fiber, disable the interface using the shutdown command to prevent exceptions caused by interference.

NOTE:
  • Running the shutdown and undo shutdown commands is equivalent to running the restart command. Running the shutdown command does not modify or delete interface configurations..
