What Is CLI?
The command line interface (CLI) enables you to interact with your device by typing text commands. At
the CLI, you can instruct your device to perform a given task by typing a text command and then
pressing Enter to submit it to your device. Compared with the graphical user interface (GUI) where you
can use a mouse to perform configurations, the CLI allows you to input more information in one
command line. The CLI of H3C devices is as shown in Figure 1-1 .
