Understanding the
Command Syntax
This section describes the steps to take when entering a command. Refer
to the sections that follow for detailed information on using the
command-line interface.
To use the command-line interface (CLI), follow these steps:
1 When entering a command at the prompt, ensure that you have the
appropriate privilege level.
Most configuration commands require you to have the administrator
privilege level.
2
Enter the command name.
If the command does not include a parameter or values, skip to Step 3. If
the command requires more information, continue to Step 2a.
a If the command includes a parameter, enter the parameter name and
values.
b The value part of the command specifies how you want the parameter
to be set. Values include numerics, strings, or addresses, depending on
the parameter.
3 After entering the complete command, press [Return].
If an asterisk (*) appears in front of the command-line prompt, it
indicates that you have outstanding configuration changes that have not
been saved. For more information on saving configuration changes, refer
to
Chapter 10 .
Syntax Helper
The CLI has a built-in syntax helper. If you are unsure of the complete
syntax for a particular command, enter as much of the command as
possible and press [Return]. The syntax helper provides a list of options
for the remainder of the command.
The syntax helper also provides assistance if you have entered an incorrect
command.
Command
Completion with
Syntax Helper
The switch provides command completion by way of the [Tab] key. If you
enter a partial command, pressing the [Tab] key posts a list of available
options, and places the cursor at the end of the command.
