Undoing Commands
When you enter a command, the command line is added to the running configuration file (running-
config).
To disable a command and remove it from the running-config, enter the no command, then the original
command. For example, to delete an IP address configured on an interface, use the no ip address
ip-address command.
NOTE: Use the help or ? command as described in Obtaining Help .
