PRODUCT OVERVIEW
The Marvell¨ Presteraª-EX family of packet processors delivers multi-layer enterprise switching with exceptional
price/performance ratios and industry-leading features. The Prestera-EX110/EX115 integrates 48 Fast Ethernet
(FE) ports, 4 Gigabit Ethernet (GbE) ports and a high-performance uplink bus for uncompromising non-blocking
performance and system scalability. It is a highly integrated system-on-a-chip (SoC) that supports full-wire-speed
L2 bridging, L3 routing and L2-L4 advanced trafÞc classiÞcation, Þltering and prioritization. The Prestera-
EX110/EX115 48 FE + 4 GbE packet processor provides the ideal solution for rapid development of high-port
density FE standalone, stackable and chassis switching systems.
