• Manufacturer Part Number: bcm5666
• Description: Strataxgs Integrated Multi-layer Switch
• Manufacturer: Broadcom Corp.

High-Density and Line Rate Performance
The BCM5666 network switch is the most advanced multi-layer
scalable, single-chip solution for high-density 48 x 10/100 Mbps ports
and 4 x 10/100/1000 Mbps Ethernet uplinks at an aggregate line rate of
28 Mpps performance.
Ultra-Scalability
An integrated 10 Gbps XAUI HiGig port allows the BCM5666 to scale
with other StrataXGS™ family switches. Multiple units can be
networked for stackable or modular switch configuration in a system
providing up to 768 of Fast Ethernet, 384 Gigabit Ethernet ports, and 32
x 10 Gigabit Ethernet interfaces. The 10 Gbps HiGig Expansion port
supports all key switch features, such as explicit priority, port trunking,
mirroring, and VC label swap functions, transparently across switch
elements.
Metro Ethernet L2 VPN Support
Supporting the latest Metro Ethernet L2 VPN applications, the
BCM5666 offers double 802.1Q VLAN stacking, also known as Q-in-
Q. This allows enterprise and service provider networks to breakthrough
the 4K VLAN tag limitation. Further, the BCM5666 also provides
MPLS tunnel/VC packet labeling for standards-based IETF L2 VPN via
MPLS.
Advanced QoS
With eight CoS queues via SP, RR, WFQ, and WRR distribution, the
BCM5666 enables full range of service applications such as low latency
VoIP and real-time video, as well as mission-critical data.

L2 Switching
Optimized for the most demanding network switching requirement, the
BCM5666 integrates a 16K entry auto-learning/aging MAC table.
Advanced Ethernet features, such as multiple and rapid spanning tree
(802.1s and 802.1w), flow control (802.3x), prioritization (802.1p), and
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).
Hardware-Based Traffic Management
Providing line rate packet filtering and classification, the advanced Fast
Filter Processor (FFP) offers ContentAware network processing per port.
The BCM5666 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.
Layer 2 Multicast
Designed for increasing multicast applications, the BCM5666 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.
