CISCO WS-F6K-DFC3B

This Cisco Catalyst 6500 Distributed Forwarding Card-3B is installed in DFC-enabled line-card modules that perform distributed forwarding supported by the Catalyst 6500 Supervisor Engine 720 as a field upgrade. When this Distributed Forwarding Card-3B is installed, modules that are DFC-enabled make forwarding decisions locally, leaving the supervisor engine free to perform routing and management functions. This Distributed Forwarding Card-3B replicates Layer 2 and 3 forwarding logic of the Supervisor 720's PFC-3 on each DFC-3B equipped line card. This enables hardware acceleration of IPv6, MPLS, GRE, QoS, ACL policy enforcement and more.
