Using the Command-Line Interface
Getting Help
You can enter a question mark (?) at the system prompt to display a list of commands available for each
command mode. You can also obtain a list of associated keywords and arguments for any command, as
shown in

Abbreviating Commands
You have to enter only enough characters for the access point to recognize the command as unique. This
example shows how to enter the show configuration privileged EXEC command:
ap# show conf
Using no and default Forms of Commands
Most configuration commands also have 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.
