How to Find Command Options
This section provides an example of how to display 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
command prompt or after entering part of a command followed by a space. The Catalyst4500 series
switch software displays a list of available keywords along with a brief description of the keywords. For
example, if you are in global configuration mode and want to see all the keywords for the arap
command, you enter arap ?.
Table1-2 shows examples of how you can use the question mark (?) to assist you in entering commands
and also guides you through entering the following commands:
• interface gigabitethernet 1/1
• channel-group 1 mode auto
