The Supervisor Engine II-Plus-10GE complements the Catalyst 4500 Series Supervisor Engine portfolio by delivering 10-Gigabit Ethernet capability in an enhanced Layer 2 supervisor engine. The Supervisor Engine II-Plus-10GE is equipped with both Gigabit (SFP) and line-rate 10-Gigabit (X2) ports, providing 10-Gigabit scalability and an easy and cost-efficient migration to 10-Gigabit Ethernet. The Supervisor Engine II-Plus-10GE provides 108Gbps of nonblocking enhanced Layer 2 switching and 81mpps throughput with basic Layer 3 and Layer 4 intelligent services. It helps enable resilient, multilayer switching solutions for converged data, voice and video networks. The Supervisor Engine II-Plus-10GE is designed with ample performance and resources to allow customers to deploy network-wide intelligent services, such as advanced quality of service (QoS), advanced security and management features, without impacting switching performance. Compatible with the widely deployed Cisco Catalyst 4503, Catalyst 4506, and Catalyst 4507R chassis as well as existing Catalyst 4500 Series line cards, the Supervisor Engine II-Plus-10GE provides investment protection while extending the deployment of the modular Cisco Catalyst 4500 Series.
