MAC(s)
The BCM5651 network switch is the most advanced multi-layer, singlechip solution for high density 24 x 10/100 Mbps ports and 4 x 10/100/
1000 Mbps Ethernet uplinks.
With an aggregate line rate of 9.5 Mpps, the BCM5651 offers hardware
switching on L2 traffic. Filtering, policing, and priority tagging can be
performed in real time with no impact on forwarding performance.
Supporting the latest Metro Ethernet L2 VPN applications, the
BCM5651 offers double 802.1Q VLAN stacking, also known as Q-inQ. This allows enterprise and service provider networks to breakthrough
the 4K VLAN tag limitation. Further, BCM5651 also provides MPLS
tunnel/VC packet labeling for standards-based IETF L2 VPN via MPLS.
With eight CoS queues via SP, RR, WFQ, and WRR distribution, the
BCM5651 enables full range of service applications such as low latency
VoIP and real-time video, as well as mission critical data.
Optimized for the most demanding network switching requirements, the
BCM5651 integrates a 16K entry auto-learning/aging MAC. Advanced
Ethernet features such as multiple and rapid spanning tree (802.1s and
802.1w), flow control (802.3x), prioritization (802.1p), and 9K jumbo
frame switching are fully integrated. All L2 traffic is switched at line
rate. For load balancing as well as redundancy purposes, link aggregation
is incorporated. Up to 32 trunk groups (eight links per group) can be
assigned for link aggregation (802.3ad).
Providing line-rate packet filtering and classification, the advanced Fast
Filter Processor (FFP) offers ContentAware network processing per port.
The BCM5651 supports TOS/DiffServ, rate limiting, policing, shaping,
metering, scheduling, priority tagging, and remapping down to flows as
small as 64 Kbps, making it ideal for committed bandwidth usage and
firewall applications.
Designed for increasing multicast applications, the BCM5651 switches
all L2 multicast packet sizes at line rate. For L2 multicast, up to 256
multicast addresses are supported. Multicast traffic can also be managed
by three port filtering modes to control the distribution behavior.
