5-Port/8-Port Gigabit Ethernet QoS Switches

88E6151/88E6181

The Marvell

Link Street

family of low power Gigabit Ethernet (GbE) switches provides industry leading functionality

and price-performance ratio for the cost-sensitive Small Office/Home Office (SOHO) and enterprise desktop switching

market. The Link Street 88E6151 (5-port) and 88E6181 (8-port) devices are GbE Quality of Service (QoS) switches

integrating a high-performance switching fabric with five (88E6151) or eight (88E6181) SERDES ports. Each switch

enables one port to be selected as a SERDES or as a fiber port that can directly drive a fiber module.

Other advanced features include 802.1p/IPv4/IPv6 traffic classification, port-based VLANs, four priority queues,

a high-speed address look-up engine, and 1 Mb of packet memory and MAC address storage. The Link Street

88E6151/88E6181 devices may be used in conjunction with Marvell Alaska

Gigabit PHYs to build a three-chip

complete Gigabit switch solution. The Link Street 88E6151/88E6181 switches perform wire-speed Gigabit switching

and are ideal products for value-oriented enterprise-class desktop switches.
