The Cisco Catalyst 4000 Family Supervisor Engine IV integrates nonblocking Layer 2/3/4 switching with integrated resiliency, further enhancing control of converged networks. Converged voice/video/data networks with high availability enable business resiliency for enterprise and metropolitan (metro) Ethernet customers deploying Internet-based business applications. As a key component of Cisco AVVID (Architecture for Voice, Video and Integrated Data), the Cisco Catalyst 4000 Family extends control from the backbone to the network edge with intelligent network services, including sophisticated quality of service (QoS), predictable performance, advanced security, comprehensive management, and integrated resiliency with Supervisor Engine IV. The modular architecture, media flexibility, and expandability of the Cisco Catalyst 4000 Family enable an extended window of deployment in converged networks. This reduces the cost of ownership by minimizing recurring operational expenses, thus improving return on investment (ROI). The Cisco Catalyst Supervisor Engine IV delivers next-generation switching technology with proven Cisco IOS Software to power scalable, intelligent multilayer switching solutions for converged voice, video, and data networks. Optimized for the enterprise wiring closet, branch-office backbones, or Layer 3 distribution points, the Cisco Catalyst Supervisor Engine IV provides the performance and scalability to handle today's and tomorrow's network applications. Compatible with the widely deployed Cisco Catalyst 4006 chassis, the Cisco Catalyst 4500 Series chassis, and existing Cisco Catalyst 4000 Series switching line cards, Supervisor Engine IV ensures an extended window of deployment to further strengthen the scalability of the modular Cisco Catalyst 4000 Family.
