Undoing Commands

When you enter a command, the command line is added to the running conguration le (running-cong).

To disable a command and remove it from the running-cong, enter the no command, then the original command. For example, to delete

an IP address congured on an interface, use the no ip address ip-address command.

NOTE: Use the help or ? command as described in Obtaining Help.
