24 CHAPTER 1: USING THE CLI
To enter commands that require parameters, enter the required
parameters after the command keyword. For example, to set a password
for the administrator, enter:
When working with the CLI, the command options are not displayed. The
command is not selected from a menu, but is manually entered. To see
what commands are available in each mode or within an Interface
Configuration, the CLI does provide a method of displaying the available
commands, the command syntax requirements and in some instances
parameters required to complete the command. The standard command
to request help is ?.
There are two instances where help information can be displayed:
■ Keyword lookup — The character ? is entered in place of a
command. A list of all valid commands and corresponding help
messages are is displayed.
■ Partial keyword lookup — If a command is incomplete and or the
character ? is entered in place of a parameter. The matched keyword
or parameters for this command are displayed.
To assist in using the CLI, there is an assortment of editing features. The
following features are described:
■ Terminal Command Buffer
■ Command Completion
■ Nomenclature
■ Keyboard Shortcuts
Terminal Command Buffer
Every time a command is entered in the CLI, it is recorded on an internally
managed Command History buffer. Commands stored in the buffer are
maintained on a First In First Out (FIFO) basis. These commands can be
recalled, reviewed, modified, and reissued. This buffer is not preserved
across device resets.
