WS-F6700-DFC3C Use Case
Data Center Spine-Leaf Scaling with WS-F6700-DFC3C Catalyst 6500 DFC
In a large enterprise data center running a spine-leaf fabric, deploying the WS-F6700-DFC3C distribution forwarding card in WS-X67xx modules offloads Layer 2/3 switching to a dedicated ASIC. This delivers 1.44 Tbps of deterministic throughput, sub-microsecond forwarding latency, and advanced MAC/route table caching. Outcome: 50 % reduction in east-west congestion, consistent sub-millisecond VM-to-VM latency, and non-disruptive addition of leaf switches to scale beyond 10,000 virtual machines.
Campus Core Aggregation for High-Performance Access with Catalyst 6500 DFC Card
A global enterprise campus network uses the WS-F6700-DFC3C in WS-X67xx modules at the core to aggregate 10/40 Gbps access uplinks. By leveraging hardware-accelerated forwarding and enhanced QoS policing, network engineers achieve deterministic traffic handling for VoIP, video conferencing, and critical application traffic. Outcome: 40 % improvement in voice packet delivery, 25 % reduction in jitter, and streamlined policy enforcement across 5,000+ edge ports.
Service Provider MPLS Edge Routing with WS-F6700-DFC3C
An ISP deploying MPLS VPN services integrates the WS-F6700-DFC3C card into WS-X67xx line cards to accelerate label switching and route-lookup operations. The card’s distributed forwarding architecture supports millions of LDP/BGP routes while maintaining wire-speed forwarding for customer traffic. Outcome: scalable PE edge density up to 8 Tbps, guaranteed SLAs with sub-microsecond forwarding jitter, and simplified network operations through centralized route management.
