The Cisco Catalyst 4928 10 Gigabit Networking Parts (4928-10GE) is a wire-speed, Layer 2 to 4, 1-rack-unit (1RU) switch designed for space-constrained LAN distribution and core applications. Based on the proven Cisco Catalyst 4500 Series hardware and software architecture, this switch offers exceptional performance, bandwidth, and reliability for medium-density, multilayer aggregation of high-performance LAN access switches. High performance and scalability of intelligent network services are made possible with dedicated specialized resources known as ternary content addressable memory (TCAM). Ample TCAM resources (64,000 entries) enable high feature capacity, providing wire-speed routing and switching performance with concurrent provisioning of services such as quality of service (QoS) and security, helping ensure scalability for today's network requirements with ample room for future growth.
