Navigating the CLI Commands
•
To display keywords and arguments for a command, enter
?
at the prompt or after entering part of a
command followed by a space:
acs/admin#
show ?
ACS displays a list and brief description of available keywords and arguments.
Note
The <cr> symbol in command help stands for “carriage return” (
Return
or
Enter
key). The
<cr> at the end of command help output indicates that you have the option to press
Enter
to
complete the command and that the arguments and keywords in the list preceding the <cr>
symbol are optional. The <cr> symbol by itself indicates that no more arguments or
keywords are available, and that you must press
Enter
to complete the command.
•
To redisplay a command that you previously entered, press the
Up Arrow
key. Continue to press the
Up Arrow
key to see more commands.
Using the No and Default Forms of Commands
Some EXEC or configuration commands have a
no
form. In general, use the
no
form to disable a
function. Use the command without the
no
keyword to re-enable a disabled function or to enable a
function disabled by default; for example, an IP address enabled by default. To disable the IP address,
use the
no ip address
command; to re-enable the IP address, use the
ip address
command.
Configuration commands can also have a
default
form, which returns the command settings to the
default values. Most commands disable by default, so in such cases using the
default
form has the same
result as using the
no
form of the command. However, some commands are enabled by default and have
variables set to certain default values. In these cases, the
default
form of the command enables the
command and sets the variables to their default values.
See
Appendix A, “ACS Command Reference,”
for a description of the complete syntax of the
configuration commands, and the
no
and default forms of a command.
