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. Compared with a graphical user interface (GUI) where you use a mouse to perform configuration,
the CLI allows you to input more information in one command line.

Telnet, and through SSH. For more information, see the chapter "Logging in to the switch configuration."
