Getting Context-Sensitive Help - HP J3138A Installation Manual

Configuring the HP AdvanceStack Internet Router
Cisco IOS Software Basics
Almost every configuration command also has a "no" form. In general, use the
"no" form to disable a feature or function. Use the command without the
keyword "no" to reenable a disabled feature or to enable a feature that is
disabled by default. For example, IP routing is enabled by default. To disable
IP routing, enter the no ip routing command and enter ip routing to reenable
it. The Cisco IOS software command reference publication provides the
complete syntax for the configuration commands and describes what the no
form of a command does. Note that you cannot override or modify a parameter
of an existing command. It must first be deleted and then use "no" form.

Getting Context-Sensitive Help

In any command mode, you can get a list of available commands by entering
a question mark (?).
To obtain a list of commands that begin with a particular character sequence,
type in those characters followed immediately by the question mark (?). Do
not include a space. This form of help is called word help, because it completes
a word for you.
To list keywords or arguments, enter a question mark in place of a keyword
or argument. Include a space before the question mark. This form of help is
called command syntax help because it reminds you which keywords or
arguments are applicable based on the command, keywords, and arguments
you have already entered.
You can also abbreviate commands and keywords by entering just enough
characters to make the command unique from other commands. For example,
you can abbreviate the show command to sh.
