Usage Guideline
The help command provides a brief description of the context-sensitive help
system, which functions as follows:
To list all commands available for a particular command mode, enter a question
mark (?) at the system prompt.
To obtain a list of commands that begin with a particular character string, enter
the abbreviated command entry immediately followed by a question mark (?).
This form of help is called word help, because it lists only the keywords or
arguments that begin with the abbreviation entered.
To list the keywords and arguments associated with a command, enter a
question mark (?) in place of a keyword or argument on the command line. This
form of help is called command syntax help, because it lists the keywords or
arguments that apply based on the command, keywords, and arguments that
have already been entered.
Example
In the following example, the help command is used to display a brief description
of the help system:
Switch# help
The switch CLI provides advanced help feature. When you need help,
anytime at the command line please press '?'.
If nothing matches, the help list will be empty and you must backup
until entering a '?' shows the available options.
Two styles of help are provided:
1. Full help is available when you are ready to enter a
command argument (e.g. 'show ?') and describes each possible
argument.
2. Partial help is provided when an abbreviated argument is entered
and you want to know what arguments match the input
(e.g. 'show ve?'.)
