Understanding Abbreviated Commands

Using the Command-Line Interface

	Command or Action	Purpose
Step 4	?	Lists all commands available for a particular command
		mode.
	Example:
	Switch> ?
Step 5	command ?	Lists the associated keywords for a command.
	Example:
	Switch> show ?
Step 6	command keyword ?	Lists the associated arguments for a keyword.
	Example:
	Switch(config)# cdp holdtime ?
	<10-255> Length of time (in sec) that receiver
	must keep this packet

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:

Switch# show conf

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 reenable 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.
