In today's highly competitive business environment, a converged network plays a critical part in helping an organization gain a competitive advantage through increased productivity, organizational flexibility, and reduced operational costs. Integration of voice, video, and data onto a single (IP-based) network requires a switching infrastructure that can distinguish each traffic type and handle itaccording to its unique requirements. TheCisco Catalyst 4500 Series provides aswitching infrastructure that, when combined with the Cisco IOS® Software, can deliver advanced functions and control.
The Cisco Catalyst 4500 Series provides the network infrastructure for Cisco AVVID that is the foundation for all applications that will be integrated to solve business problems. Extending intelligent network services with integrated resiliency leads to control of all traffic types with minimal downtime. The Cisco Catalyst 4500 Series delivers this control with:
•Integrated resiliency—Network downtime is minimized with redundant supervisor engine capability (Cisco Catalyst 4507R adn 4510R), software-based fault tolerance, and 1+1 power supply redundancy across the Cisco Catalyst 4500 Series. Integrated Power over Ethernet (PoE) in all Cisco Catalyst 4500 Series chassis simplifies network design and limits the number of points of failure in an IP telephony implementation.
•Sophisticated QoS—Integrated Layers 2 through 4-based QoS and traffic management capabilities classify and prioritize mission-critical and time-sensitive traffic based on 32,000 QoS policy entries. The Cisco Catalyst 4500 Series can shape and rate-limit bandwidth-intensive traffic with mechanisms such as input and output policers based on host, network, and application information.
•Predictable performance—The Cisco Catalyst 4500 Series offers up to a 72-Mpps wire-speed forwarding rate in hardware for Layers 2-4 traffic. Switching performance is independent of the number of route entries or advanced Layer 3 services enabled.
•Advanced security—The Cisco Catalyst 4500 Series supports up to 32,000 wire-rate Layers 2 through 4 access list entries, and includes other advanced security capabilities such as user authentication and client security.
•Comprehensive management—The Cisco Catalyst 4500 Series offers Web-based management for the configuration and control of all ports, allowing central management of critical network characteristics such as availability and responsiveness.
As convergence lowers the overall cost of network ownership and simplifies administration and maintenance through the elimination of separate voice, video, and data infrastructures, it makes sense for companies to seek these qualities in the network infrastructure itself. The modular architecture of the Cisco Catalyst 4500 Series provides the scalability and flexibility to eliminate the need for multiplatform deployments, minimizing maintenance expenses. Now with integrated resiliency, the Cisco Catalyst 4500 Series can increase workforce productivity, profitability, and customer success to all corporations implementing converged network infrastructures.
