Cisco Systems® announces distributed forwarding cards with enhanced features for CEF720-based line cards.

The Cisco ® Catalyst ® 6500 Series Distributed Forwarding Card 3 (DFC3), including WS-F6700-DFC3A (DFC3A), WS-F6700-DFC3B (DFC3B), WS-F6700-DFC3BXL (DFC3BXL), is an optional daughter card for CEF720-based line cards such as WS-X6704-10GE, WS-X6724-SFP, WS-X6748-SFP, and WS-X6748-GE-TX. The DFC3 provides localized forwarding decisions for each line card and scales the aggregate system performance to reach up to 400 mpps. The new DFC3B and DFC3BXL offer enhancements to support Multiprotocol Label Switching (MPLS) and Access Control Entries (ACE) counters on the Cisco 6700 Series line cards. The DFC3BXL also has improved scalability to support one million IPv4 routes and 256-KB NetFlow entries.
