General Description
The BCM5696 is an integral component of the highly modular switch
architecture. Each port supports 10/100/1000-Mbps Ethernet with
copper or fibre physical interfaces. The BCM5696 has a fully integrated
SerDes with an SGMII interface on the GbE ports. The flexibility and
modularity of the BCM5696 switch architecture makes it suitable for a
wide range of applications including fixed, blade server, and metro
Ethernet switching.
Advanced QoS
The highly flexible ContentAware packet filtering and classification
engine in the BCM5696 switch family provides a common application
platform across the entire StrataXGS™ product line. It supports
ToS/DiffServ, rate limiting, policing, shaping, marking, and remarking.
These features enable cutting-edge voice and video applications based
on the Internet Protocol.
Multi-Service Intelligence
Superior scalability, high availability, and performance enable network
designers to meet the growing needs of mission-critical enterprise
applications. Support of multi-service intelligence in the form of
FLASH
integrated security (IEEE 802.1x), wirespeed access control lists, policybased rate limiting, IP Multicast replication, IPv6 awareness, and
advanced Layer 3 functionality ensures robust network design.
New metro Ethernet features extend the security boundary beyond the
enterprise networks into service provider networks with support for
double VLAN tagging (IEEE 802.1Q) and VLAN translation.
Superior Performance
The BCM5696 delivers wirespeed switching performance across all
ports simultaneously. The BCM5696 also introduces very low switching
latency, enabling very high-quality transmission of voice, video, and
data traffic. The BCM5696 supports advanced packet flow control such
as head-of-line blocking prevention and IEEE 802.3x-compatible fullduplex control.
