Overview
The Catalyst 4500 Series with CenterFlex technology provides scalable nonblocking 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 includes two series of Catalyst chassis: the E-Series and Classic
Series chassis. Catalyst 4500 E-Series chassis are extremely flexible and will support both 6 Gbps
and 24Gbps per line card slot. The Classic Catalyst 4500 Series chassis supports 6 Gbps per line
card slot. There are four models of Catalyst 4500 E-Series and Catalyst 4500 classic chassis: ten-
slot, seven-slot, six-slot and three-slot. Integrated resiliency enhancements offered in the Catalyst
4500-E and Classic Series include 1+1 supervisor-engine redundancy (Ten-slot and seven-slot
only) redundant fans, software-based fault tolerance, and 1+1 power-supply redundancy.
Integrated resiliency in both hardware and software minimizes network downtime, helping to
ensure workforce productivity, profitability, and customer success.
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
