The Cisco Supervisor Engine 720 offers a strong set of security features. System security is hardened with support for features such as Port Security, CPU rate limiting, Multi-Path uRPF and a long list 802.1x extension. Extensive feature support such as QoS mechanisms, hardware-based generic-routing-encapsulation (GRE) tunneling, and access control lists (ACLs) enable customers to build high-performance, feature-rich campus networks, metropolitan (metro) aggregation, and various WAN edge networks. With enhanced security, rich QoS and scalable performance for Gigabit and 10gigabit, the Sup720 is ideal for enterprise core and distribution and datacenters. The Supervisor

Engine 720 builds on the proven Cisco Express Forwarding (CEF) architecture, by supporting centralized forwarding (CEF) and distributed forwarding (dCEF). The variants of PFC3 distinguish the various Supervisor 720 families of engines. There are three flavors, PFC3A, PFC3B and PFC3BXL, correspond to WS-SUP720, WS-SUP720-3B and WS-SUP720-3BXL. The Supervisor Engine 720 family is supported on both operating systems-Cisco Catalyst OS^® and Cisco IOS^®. The Supervisor Engine 720 delivers scalable-performance, intelligence, and a broad set of features to address the needs of the most demanding service provider and enterprise deployment requirements for building modular, resilient, scalable, and secure layer 2 or layer 3 solution by:

·         Delivering scalable forwarding Performance: up to 400 Mpps¹ IPv4 and 200 Mpps IPv6 with dCEF

·         Multi-Protocol Label Switching support (MPLS) in hardware: enabling the use of VPNs and layer 2 tunneling while improving traffic engineering for QoS

·         Delivering up to 40 Gbps per slot of switching capacity; 720 Gbps aggregate bandwidth

·         Providing support for new high performance next generation gigabit and 10Gigabit interfaces
