erations. The command syntax for CLI is the same as that of the menu driven
interface. The only difference is that the menu driven interface shows you all of
available commands for you to select. You don't need to remember the com-
mand syntax and save your time on typing 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 GRT-101, move down the cursor by pressing
key K twice and select "show" command by key L, you shall see a submenu
and select "system" command in this submenu, then the system will show you
the general information.
In this chapter, all configuration procedures are explained by command line
examples with necessary parameters. When operating in the menu driven in-
terface, just select the corresponding command items from the menu hierarchy
to configure the same setting.
Note: GRT-101 invokes menu driven interface when first time logon with default user profile "admin". Both interfaces
have on-line help information. To get on-line help, type "?" for CLI mode or press CTRL+Q for menu driven interface.
