About the Command Line Interface
To use and navigate the command line interface of your unit, please refer to the following points for assistance:
â– When initially accessing the command line interface, press Enter when prompted. The User View menu for the unit is
displayed. This is indicated by the chevron brackets around the name of the unit at the prompt, for example,
<4500G>.
â– When in the System View menu, square brackets appear around the name of the unit at the prompt, for example,
[4500G].
â– You must be in the System View menu to access the configurable CLI commands.
â– Some commands can be entered directly at any prompt from anywhere in the interface.
â– If you enter part of a command followed by a ? (with no space between), the CLI will show you all the commands
that begin in that way.
■The term ‘view’ may be used interchangeably with the term ‘menu’.
â– The undo command is placed before the command you wish to undo, for example, undo setauthentication password.
â– <CTRL-A> places the cursor back to the start of the command line.
â– Enter the first few characters of a command and press TAB to enter the full command without having to input the
entire command (where there is only one command that starts with the entered characters).
â– Use the Up Arrow key at the prompt to repeat the previous command string.
â– Use the Delete key to delete the character after the cursor; the Backspace key deletes the character before the cursor.
â– When entering physical port numbers, Enter the port number as x/0/z, where x is the unit number and z is the
physical port number.
