The Catalyst 4500 Series with CenterFlex technology provides scalable non-blocking Layer 2-4 switching with secure, flexible, non-stop communications, enabling business resilience for enterprises, small and medium-sized businesses (SMBs), and Metro Ethernet customers deploying business-critical applications. CenterFlex technology is the technology enabled by the Supervisor 6-E centralized ASICs, which deliver the highest centralized performance and configuration flexibility in the industry. CenterFlex technology enables granular optimization of real-time voice, video and data communication, maximizing performance and enhancing end user experience. The new "E-Series" with CenterFlex technology is designed with unprecedented backward and forward compatibility delivering exceptional investment protection and deployment flexibility to meet the evolving needs of organizations of all sizes. The Cisco Catalyst 4500 Series extends control to the network edge with intelligent network services, including sophisticated quality of service (QoS), predictable performance, advanced security, comprehensive management, and integrated resiliency. Scalability of these intelligent network services is made possible with dedicated specialized resources known as ternary content addressable memory (TCAM). Ample TCAM resources (up to 384.000 entries) enable "high feature capacity," which provides wire-speed routing/switching performance independent of provisioning of services such as QoS and security. This helps ensure scalability for today's network requirements with ample room for future growth. With unprecedented forward and backward compatibility spanning multiple generations, the Catalyst 4500 Series reduces the cost of ownership by minimizing recurring operational expenses, improving return on investment (ROI). The Cisco Catalyst 4500 E-Series provides a common architecture that can scale up to 388 ports. The Cisco Catalyst WS-C4510R-E offers high availability in supporting 1+1 redundant supervisor engines with subsecond failover time and full image In Service Software Upgrades (ISSU). Using the same line cards as the widely deployed legacy Catalyst 4000 Series Switches and Classic Catalyst 4500 Series Switches, the Catalyst 4500-E Series enhances the Cisco commitment to affordable enterprise and branch scalability. It provides a cost-effective, flexible network solution that scales to meet today's high-performance needs with investment protection.
