The Cisco Catalyst 6500 Series switch fabric modules, including this Switch Fabric Module, in combination with the Supervisor Engine 2, deliver an increase in available system bandwidth from the existing 32Gbps to 256 Gbps. This significant increase in available bandwidth ensures that the Cisco Catalyst 6500 Series continues to deliver not only best-in-class bandwidth, but also the performance and advanced services required for today's most advanced networks.The Switch Fabric Module provides frameworks for delivering high-bandwidth architecture. This switch fabric module is key enabler for the optional distributed forwarding architecture that facilitates convergence of high traffic volumes at different parts of the network. The Switch Fabric Module enables a new architecture that allows 30 Mpps of Cisco Express Forwarding (CEF)-based central forwarding performance on Supervisor Engine 2 and up to 210 Mpps of distributed forwarding performance. The higher bandwidth and performance enabled by the switch fabric modules, coupled with advanced services such as quality of service (QoS) and security in hardware via access control lists (ACLs), make the Cisco Catalyst 6500 Series the premier platform for service providers and enterprises.This Switch Fabric Module is supported in the Catalyst 6506 and Catalyst 6509 only.
