What Is CLI?
The command line interface (CLI) is an interface where you can 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 pointer to click on options for configuration, the CLI allows you to input a
command containing more information at one time. On the H3C switch series, which deliver powerful
functions, it is faster to perform configurations by using the CLI. The CLI of H3C switches is as shown in
Figure 1-1 .
