Designed specifically for use with the Cisco Catalyst 6500 Series Supervisor Engine 720, the WS-X6724-SFP features 24 Gigabit Ethernet ports that use a 20-Gbps connection to the 720-Gbps switch fabric. As a result, this CEF720-based module can be deployed in every Cisco Catalyst 6500 Series chassis slot, increasing modular fiber-based Gigabit Ethernet port density to 288 ports in a single Cisco Catalyst 6513 chassis.
