Cisco Supervisor Engine 2T XL - For Data Networking, Optical Network - 125 MB/s Gigabit Ethernet, 1.25 GB/s 10 Gigabit Ethernet - 3 x SFP (mini-GBIC) , 2 x X2 1000 Mbit/s - 5 x Expansion Slots VS-S2T-10G-XL-RF

Policy Feature Card 4 Supervisor Engine 2T features the integrated Policy Feature Card 4 (PFC4), which improves performance and scalability and provides new and enhanced hardware features. The PFC4 is equipped with a high-performance ASIC complex that enables hardware acceleration for existing and new 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 new innovations such as native VPLS, flexible NetFlow, egress NetFlow, Cisco TrustSec, distributed policers, control plane policing, and comprehensive IPv6 features.
