In a Fortune 500 enterprise data center, the WS-F6700-DFC3B Catalyst 6500 Distribution Forwarding Card enables converged routing for over 200,000 VLANs and 256K routes. By offloading inter-VLAN/MPLS routing to dedicated hardware, latency drops by 40% and core switch CPU utilization decreases by 75%, ensuring deterministic performance and capacity for virtualization, big data analytics, and east-west traffic.
A global telecom operator leverages the WS-F6700-DFC3B on its Catalyst 6500 series to support multi-gigabit MPLS/VPN services across 256K routes. The card’s hardware-based forwarding delivers sub-microsecond packet processing, enabling seamless on-net/off-net peering, automated failover, and line-rate subscriber aggregation. Outcome: 99.999% service availability and 30% faster L3 convergence in large-scale edge POPs.
In a large university campus network, the WS-F6700-DFC3B Distribution Forwarding Card is deployed in redundant Catalyst 6500 chassis to manage 256K dynamic OSPF/BGP routes across academic, administrative, and research VLANs. Hardware-accelerated forwarding ensures sub-millisecond convergence during link failures, delivering 100% SLA adherence for VoIP, remote labs, and e-learning platforms while reducing network jitter by 50%.
