In addition, after typing any given command plus one space, users can see all of the next possible
sub-commands, in sequential order, by repeatedly pressing the Tab key.
To re-enter the previous command at the command prompt, press the up arrow cursor key. The
previous command will appear at the command prompt.
DGS-3420-28SC:admin# config account
Command: config account
Next possible completions:
<username>
DGS-3420-28SC:admin# config account
In the above example, the command config account was entered without the required parameter
<username>, the CLI returned the Next possible completions: <username> prompt. The up
arrow cursor control key was pressed to re-enter the previous command (config account) at the
command prompt. Now the appropriate username can be entered and the config account
command re-executed.
All commands in the CLI function in this way. In addition, the syntax of the help prompts are the
same as presented in this manual − angle brackets < > indicate a numerical value or character
string, braces { } indicate optional parameters or a choice of parameters, and brackets [ ] indicate
required parameters.
If a command is entered that is unrecognized by the CLI, the top-level commands will be displayed
under the Available commands: prompt.

The top-level commands consist of commands such as show or config. Most of these commands
require one or more parameters to narrow the top-level command. This is equivalent to show what?
or config what? Where the what? is the next parameter.
For example, entering the show command with no additional parameters, the CLI will then display
all of the possible next parameters.
