Understanding Abbreviated Commands
Understanding Abbreviated Commands
You need to enter only enough characters for the switch to recognize the command as unique.
This example shows how to enter the show configuration privileged EXEC command in an abbreviated form:
Controller# show conf
Understanding no and default Forms of Commands
Almost every configuration command also has a no form. In general, use the no form to disable a feature or
function or reverse the action of a command. For example, the no shutdown interface configuration command
reverses the shutdown of an interface. Use the command without the keyword no to re-enable a disabled
feature or to enable a feature that is disabled by default.
Configuration commands can also have a default form. The default form of a command returns the command
setting to its default. Most commands are disabled by default, so the default form is the same as the no form.
However, some commands are enabled by default and have variables set to certain default values. In these
cases, the default command enables the command and sets variables to their default values.
