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 Table 6-2.

Table 6-2 Help Summary

Command	Purpose
help	Obtains a brief description of the help system in any command mode.
abbreviated-command-entry?	Obtains a list of commands that begin with a particular character string.
	For example:
	br# di?
	dir disable disconnect
abbreviated-command-entry<Tab>	Completes a partial command name.
	For example:
	br# sh conf<tab>
	br# show configuration
?	Lists all commands available for a particular command mode.
	For example:

command ?	Lists the associated keywords for a command.
	For example:
	br> show ?
command keyword ?	Lists the associated arguments for a keyword.
	For example:
	br(config)#	cdp holdtime ?
	<10-255>	Length of time (in sec) that receiver must keep this packet

Abbreviating Commands

You have to enter only enough characters for the access point/bridge to recognize the command as unique. This example shows how to enter the show configuration privileged EXEC command:

br# 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.
