Undoing Commands
When you enter a command, the command line is added to the running configuration file. Disable a
command and remove it from the running-config by entering the original command preceded by the
command no. For example, to delete an ip address configured on an interface, use the no ip address
ip-address command, as shown in Figure 2-5.
Note: Use the help or ? command as discussed in Obtaining Help command to help you construct the “no”
form of a command.
Figure 2-5. Undoing a command with the no Command
Layer 2 protocols are disabled by default. Enable them using the no disable command. For example, in
PROTOCOL SPANNING TREE mode, enter no disable to enable Spanning Tree.
