WSFSK-DFC Daughter Card 32284-12

The Catalyst 6500 Distributed Forwarding Card is installed in DFC-enabled line-card modules that perform distributed forwarding supported by the Catalyst 6500 Supervisor Engine 2 as a field upgrade. These line cards include the WS-X6516-GBIC and the WS-X6816-GBIC.

Key Features:

  • When the Distributed Forwarding Card is installed, Line cards that are DFC-enabled make forwarding decisions locally, leaving the supervisor engine free to perform routing and management functions
  • The Distributed Forwarding Card supports Cisco¬ís distributed Cisco Express Forwarding (CEF)-based forwarding architecture
  • The Distributed Forwarding Card replicates Layer 2 and 3 forwarding logic in hardware as well as a bus on each line card
