Cisco WS-F6700-DFC3C is a Distributed Forwarding Card 3C (DFC3C) designed for Cisco Catalyst 6500 Series and Cisco 7600 Series platforms. It is an optional daughter card installed directly onto compatible CEF720 line cards, enabling distributed forwarding (dCEF) instead of centralized forwarding through the supervisor engine. This significantly improves performance and scalability in large enterprise and service provider networks.

The DFC3C provides hardware-based forwarding for:

• Layer 2 switching
• Layer 3 routing
• QoS
• ACL processing
• IPv4 / IPv6 forwarding

? KEY FEATURES
