WS-C4928-10GE, Catalyst 4928, ES Software, 28-Port 10/100/1000, 2 Port 10GE (X2), 1 AC Power Enhanced Layer 3 image, including Open Shortest Path First (OSPF), Intermediate System-to-Intermediate System (IS-IS), EIGRP, Border Gateway Protocol (BGP), AppleTalk, and Internetwork Packet Exchange (IPX) software routing; also includes all IP Base image features.

The Cisco® Catalyst® 4928 10 Gigabit Ethernet Switch (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.

The Cisco Catalyst 4948 offers 48 ports of wire-speed 10/100/1000BASE-T with four alternative wired ports that can accommodate optional 1000BASE-X Small Form-Factor Pluggable (SFP) optics1. Exceptional reliability and serviceability are delivered with optional internal AC or DC 1+1 hot-swappable power supplies and a hot-swappable fan tray with redundant fans.
