Finding Command Options
This section provides an example of how to find and display the syntax for a command. The syntax
can consist of optional or required keywords. To display keywords for a command, enter a question
mark (?) at the configuration prompt, or after entering part of a command followed by a space.
The Cisco IOS software displays a list of keywords available along with a brief description of the
keywords. For example, if you were in global configuration mode, typed the command arap, and
wanted to see all the keywords for that command, you would type arap ?.
The following table shows you how to find the command options for the following two commands:
• controller t1 1
• cas-group 1 timeslots 1-24 type e&m-fgb dtmf
