Supervisor Engine 2T
Primary Supervisor Engine 2T Components
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 ACL 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.
Multilayer Switch Feature Card 5
Supervisor Engine 2T features the Multilayer Switch Feature Card 5 (MSFC5), providing
high-performance, multilayer switching and routing intelligence. Equipped with a high-performance
processor, the MSFC5 runs both Layer 2 protocols and Layer 3 protocols on the dual-core CPU complex.
These include routing protocol support, Layer 2 protocols (for example, Spanning Tree Protocol and
VLAN Trunking Protocol), and security services.
The MSFC5 builds the Cisco Express Forwarding information base (FIB) table in software and then
downloads this table to the hardware application-specific-integrated circuits (ASICs) on the PFC4 and
Distributed Forwarding Card 4 (DFC4), if present on a module, which make the forwarding decisions
for IP unicast and multicast traffic.
