Command Line Interface
Introduction
The CLI is used for viewing switch information and statistics. In addition, the administrator can use the CLI for
performing all levels of switch configuration.
To make the CLI easy to use, the various commands have been logically grouped into a series of menus and
submenus. Each menu displays a list of commands and/or submenus that are available, along with a summary of
what each command will do. Below each menu is a prompt where you can enter any command appropriate to the
current menu.
This chapter describes the Main Menu commands, and provides a list of commands and shortcuts that are
commonly available from all the menus within the CLI.
Main Menu
The Main Menu displays after a successful connection and login. The following table shows the Main Menu for the
administrator login. Some features are not available under the user login.
