24-PORT GIGABIT ETHERNET MULTILAYER SWITCH WITH

THREE 10-GIGABIT ETHERNET/HIGIG+™ PORTS

FEATURES

SUMMARY OF BENEFITS

• 24 10/100/1000 Mbps Ethernet ports supporting both copper

and fiber connections

• Fifth generation of StrataSwitch® and StrataXGS® product

line

• High-density value Gigabit Ethernet (GbE) product line, pin-

compatible to feature GbE BCM56503

• Three 12-Gbps or 10-Gbps HiGig+™ port uplink interfaces

• Three 10-GbE switching ports, CX4 support

• Line-rate switching for all packet sizes and conditions

• On-chip data packet memory and table memory

• IPv6 routing and tunneling

• Advanced Fast Filter Processor (FFP) ContentAware™

classification

• Advanced security features in hardware

• Port trunking and mirroring supported across stack

• Advanced packet flow control:

• Head-of-line blocking prevention

• Back pressure support

• Eight QoS queues per port with hierarchical minimum/

maximum shaping per Classes of Service (CoS) per queue per

port

• Standard compliant 802.1ad provider bridging

• Highly-scalable architecture evolved from five generations of

switching experience provides rich features, scalability, and

future-proof solutions.

• Optimized for secure switching and convergence of

applications and services in the networks.

• System vendors can build scalable high-performance, high-

port density GbE LAN switches in several form factors.

• Multiple CoS and low latency enable the support of VoIP and

other voice, video, and data applications.

• Built-in high-speed serial interfaces with Broadcom-unique

SerDes technology eases and accelerates system design, while

reducing cost and conserving board space.

• Broadcom switch API compatibility enables software reuse

and faster time-to-market.

• Small package and low power enables cost-effective and high-

performance system design.
