The Cisco Catalyst 4500 Series integrates security and resiliency for advanced control of converged networks.
The Cisco Catalyst 4500 Series Supervisor Engine V continues the nonblocking, robust Layer 2-4 switching found in previous Cisco Catalyst 4500 Series Supervisor Engines. Additional performance, features, and throughput further enhance resilient control of converged data, voice, and video networks, with high availability enabling 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 scalability of these intelligent network services is made possible with dedicated specialized resources known as ternary content addressable memory (TCAM). Ample TCAM resources (192,000 entries) enable "high feature capacity," which provides wire-speed routing and switching performance while enabling services such as QoS and security. This helps meet today's network requirements, with ample room for future growth.
The Cisco Catalyst 4500 Series Supervisor Engine V offers port scalability for resilient Layer 2-4 and routing for both the enterprise and service provider market segments. Optimized for the enterprise wiring closet, branch office backbone, or Layer 3 distribution point, the Cisco Catalyst 4500 Series Supervisor Engine V provides the performance and scalability to handle the network applications of today and the future.
The Cisco Catalyst 4500 Series modular architecture provides a "pay as you grow" model, reducing operational expenses and capital expenditures. The Supervisor Engine V is backward-compatible with all the classic Cisco Catalyst 4500 Series line cards and can be used in both the classic Cisco Catalyst 4500 Series chassis (Catalyst 4503, Catalyst 4506, Catalyst 4507R, and Catalyst 4510R) and with the Cisco Catalyst 4500 E-Series chassis (Catalyst 4503-E, 4506-E, 4507R-E, and 4510R-E).
Predictable Performance and Scalability
The Cisco Catalyst 4500 Series Supervisor Engine V delivers a 96-Gbps switching fabric with a 72-mpps forwarding rate in hardware for Layer 2-4 traffic. Switching performance is independent of the number of route entries or Layer 3 and 4 services enabled. Hardware-based Cisco Express Forwarding routing architecture allows for increased scalability and performance. Table 2 provides a comparison of the performance and scalability features of all of the Cisco Catalyst 4500 Series Enhanced Layer 3 Supervisor Engines.
IPv6 is important for the future of IP networking and is critical for the expansion of IP address space in the future. IPv6 capability is required by many companies and is being mandated by governments worldwide. IPv6 has been supported on the Cisco Catalyst 4500 Supervisor Engine V since Cisco IOS Software Release 12.2(20) EW with software-based forwarding.
