Supervisor Engine Software

The supervisor engine software is factory installed on every supervisor engine module or fixed-configuration switch. Some modules require an additional software image, which is factory installed on the module.

The Catalyst enterprise LAN switches share a command-line interface (CLI) with which you can configure modules and ports on the switches. For more information, see "Using the Command-Line Interface." For descriptions of the available CLI commands, refer to the Command Reference—Catalyst 4000 Family, Catalyst 2948G, and Catalyst 2980G Switches.
