Figure 2-4.  Using the Up Arrow to Re-enter a Command 
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 user name 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.

Figure 2-5.  The Next 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, if you enter the show command with no additional parameters, the CLI will then display all of the possible next 
parameters.
