Description

Distributed Forwarding Card (DFC3C) that offloads L2/L3, IPv4/IPv6, ACL, QoS, and NetFlow to the line card for lower latency and higher scalability on fabric-enabled 67xx/ES modules. Ideal for large routing tables and feature-rich edge or core deployments. Verify PFC class and software compatibility with your supervisor engine and chassis before install.

Features

- Distributed hardware forwarding for reduced CPU load
- IPv6, MPLS, NetFlow, and QoS offload on supported line cards
- Improves scalability for large FIB/ACL deployments
- Supports high availability frameworks with compatible supervisors

FAQs

Q: Which line cards support this DFC?
A: Fabric-enabled WS-X67xx and ES-series line cards designed for DFC3C. Check the specific line card PID and Cisco release notes to confirm support.

Q: Does it require a specific supervisor?
A: It should be paired with a supervisor using a matching PFC class (PFC3C). Mixing with other classes can reduce features or be unsupported.

Q: What software features are enabled by the DFC?
A: Hardware offload for L2/L3 forwarding, IPv6, ACLs, NetFlow, QoS, and MPLS—subject to line-card and IOS feature set.
