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.

Example of Viewing Disabled Commands

DellEMC(conf)#interface tengigabitethernet 2/17
DellEMC(conf-if-te-2/17)#ip address 192.168.10.1/24
