Each port supports 10/100/1000-Mbps Ethernet with copper or fibre physical interfaces. The BCM5696 has a fully integrated New metro Ethernet features extend the security boundary beyond the SerDes with an SGMII interface on the GbE ports. The flexibility and enterprise networks into service provider networks with support for modularity of the BCM5696 switch architecture makes it suitable for a double VLAN tagging (IEEE 802.1Q) and VLAN translation. wide range of applications including fixed, blade server, and metro Ethernet switching. Superior Performance The BCM5696 delivers wirespeed switching performance across all Advanced QoS ports simultaneously. The BCM5696 also introduces very low switching The highly flexible ContentAware packet filtering and classification latency, enabling very high-quality transmission of voice, video, and engine in the BCM5696 switch family provides a common application data traffic. The BCM5696 supports advanced packet flow control such platform across the entire StrataXGS product line. It supports as head-of-line blocking prevention and IEEE 802.3x-compatible full- ToS/DiffServ, rate limiting, policing, shaping, marking, and remarking. duplex control. These features enable cutting-edge voice and video applications based on the Internet Protocol. Additional Information Production-ready reference design kits enable faster time-to-market for Multi-Service Intelligence system vendors and come with extensive support documentation and Superior scalability, high availability, and performance enable network software.
