The Cisco Catalyst 4500 Series Supervisor Engine V-10GE continues the nonblocking, robust Layer 2-4 switching found in previous Cisco Catalyst 4500 Series supervisor engines with the addition of wire-speed 10-Gigabit Ethernet uplinks, 136-Gbps capacity and 102-mpps throughput, and additional features to further enhance resilient control of converged data, voice, and video networks with high availability to help enable business resiliency for enterprise and metropolitan (metro) Ethernet customers. Network control extends from the backbone to the edge with intelligent services such as granular quality of service (QoS), Internet security, and network management. The Cisco Catalyst Supervisor Engine V-10GE includes dual wire-speed 10-Gigabit Ethernet ports (X2 optics) as well as 4 alternative wired Gigabit Ethernet ports (Small Form-Factor Pluggable [SFP] optics) on the faceplate to maximize the flexibility of deployment options. The combination of Gigabit Ethernet and 10-Gigabit Ethernet ports on the same supervisor engine allows for network future-proofing with an easy migration path from Gigabit Ethernet to 10 Gigabit Ethernet by simply adding 10-Gigabit Ethernet optical interfaces. The ability to choose between Gigabit Ethernet uplinks and 10-Gigabit Ethernet uplinks on a single supervisor engine further enhances the investment protection of the Cisco Catalyst 4500 Series architecture.
