Cisco Policy Feature Card 4 XL - control processor

The integrated Policy Feature Card 4 (PFC4) improves performance and scalability and provides enhanced hardware features. The PFC4 is equipped with a high-performance ASIC complex that enables hardware acceleration for existing and software features. The PFC4 supports Layer 2 and Layer 3 forwarding, QoS, Netflow and Access Control List (ACLs) and multicast packet replication and processes security policies such as access control lists (ACLs) operations all simultaneously enabled with no performance impact. The PFC4 supports all of these operations for both IPv4 and IPv6. PFC4 also provides enhanced performance and scalability and supports many innovations such as native VPLS, flexible NetFlow, egress NetFlow, Cisco TrustSec, distributed policers, control plane policing, and comprehensive IPv6 features.
