New and Used Cisco WS-SUP720-3B Supervisor Engines for Sale (WSSUP7203B)

WS-SUP720-3B Product Specifications

The Cisco Catalyst 6500 Series Supervisor Engine 720 is designed to scale and deliver a rich set of hardware features enabling scalability with performance. The hardware-based feature set can enable applications, such as Layer 2 and Layer 3 Multiprotocol Label Switching (MPLS) VPNs and Ethernet over MPLS (EoMPLS), with quality of service (QoS) and security. The Supervisor Engine 720 integrates a high-performance 720 Gbps crossbar switch fabric with a new forwarding engine in a single module, delivering 40 Gbps of switching capacity per slot (enabling 4-port 10 Gigabit Ethernet and 48-port 10/100/1000 density line cards). With hardware-enabled forwarding for IPv4, IPv6, and MPLS, the performance delivered is 400 million packets per second (mpps) of IPv4, 200 mpps of IPv6 traffic with features, and 1000 VPN Routing/Forwarding instance (VRF) with up to 700 routes/VRF for MPLS.

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 MSFC3 is an integral part of the Supervisor Engine 720, providing high performance, multilayer switching and routing intelligence. Equipped with a high performance processor, the MSFC runs layer 2 protocols on one CPU and layer 3 protocols on the second CPU. These include routing protocol support, layer 2 protocols (Spanning Tree Protocol and VLAN Trunking Protocol for example), and security services. The Supervisor Engine 720 features the PFC3, which is equipped with a high-performance ASIC complex supporting a range of hardware-based features. The PFC3 supports routing and bridging, QoS, and multicast packet replication, and processes security policies such as access control lists (ACLs).
