The help command is in all command modes and displays a brief message about
using the CLI help system. The syntax for the
help command is:
help
The help command has no parameters or variables.
Figure 4 shows the output from the
help command.

no command
The no command is always used as a prefix to a configuration command, and it
negates the action performed by that command. The effect of the
no command is
to remove or to clear the configuration controlled by the specified command.
Various
no commands are in the config and config-if command modes.
Refer to Appendix A for an alphabetical listing of all
no commands.
Note: Not all configuration commands support the no prefix
command.
BPS2000#help
Help may be requested at any point in a command by entering
a question mark ’?’. 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 pr?’.)
