The Cisco Catalyst 2912MF XL Fast Ethernet switch combines outstanding performance, ease of use, and integrated Cisco IOS software from the leader in networking. The Catalyst 2912MF XL is a flexible, scalable, and affordable solution, ideal for aggregating Fast Ethernet workgroups over 100Base-FX connections in small and midsized campus environments. The Catalyst 2912MF XL switch, a member of the Catalyst 2900 Series XL family, contains 12 100Base-FX ports and two versatile module slots to provide unmatched expansion capabilities and high-speed connectivity. The modular design allows users to easily add 10Base-T/100Base-T, 100Base-FX, Gigabit Ethernet, or ATM (OC-3) ports to increase port density and deliver high-speed uplinks. With the Gigabit Ethernet module, Catalyst 2912MF XL switches (as well as the Catalyst 2924M XL switch) can be stacked (up to nine switches) with the low-cost Cisco GigaStack GBIC. The advanced Cisco architecture incorporates a switch fabric of 3.2 Gbps and a forwarding rate of 3.0 million pps to deliver wire-speed performance across all ports.
