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.
