Key Features of Cisco 48 port 1000Base-X SFP Gigabit Ethernet Module
The Cisco Catalyst 4500 Series Classic line cards provide 6 gigabits of switching capacity per slot. Classic line cards may be deployed in both classic and E-Series chassis with either classic Cisco Catalyst 4500 Series supervisor engines or with the Supervisor Engine 6-E. With the Supervisor Engine 6-E, the classic line cards per slot switching capacity remains at 6 gigabits per slot. However, because of the centralized switching architecture of the Cisco Catalyst 4500, the classic line cards will adopt all of the new Supervisor Engine 6-E features such as eight queues per port, dynamic QoS, and hardware-based IPv6 routing.
