14.3 Operation Interface
For serial console and Telnet management, the Router implements two operational interfaces: command line
interface (CLI) and menu driven interface. The CLI mode provides users with a simple command line interface.
The menu driven interface is a more user-friendly interface for general operations. The command syntax for CLI
is the same as that of the menu driven interface. The only difference is that the menu driven interface displays all
available commands for you to select. This means that you don’t need to remember the command syntax and can
save you time by not requiring you to type the whole command line.
The following figure gives you an example of the menu driven interface. In the menu, you scroll up/down by
pressing key I / K, select one command by key L, and go back to a higher level of menu by key J. For example, to
show the system information, just logon to the Router, move down the cursor by pressing key K twice and select
“show” command by pressing key L, you shall see a submenu and select “system” command in this submenu,
then the system will display the general information.
