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.
