MULTILAYER 2-PORT 10 GIGABIT ETHERNET AND HiGig™ SWITCH

FEATURES

SUMMARY OF BENEFITS

• One 10 Gbps IEEE 802.3ae compliant Ethernet port

• One HiGig™ port configurable for 10 Gbps speed

• Integrated on-chip 512 KB packet buffer memory

• Integrated on-chip layer 2/3 tables

• Supports wire speed switching for all packet sizes, including

jumbo frames (up to 9 KB)

• Supports eight class of service (CoS) queues

• Supports advanced packet flow control:

• Head-of-line blocking prevention

• Full-duplex flow control (IEEE 802.3x compatible)

• ContentAware™ network processing per port:

• Line rate deep packet classification

• Supports IEEE 802.1p, ToS/DiffServ, rate limiting, policing,

priority tagging, and re-mapping

• Provides hardware support for IP multicast and IP multicast

replication

• Support for double VLAN tagging with loopback feature

• Support for 128 StrataXGS™ devices using module remapping

• Supports port mirroring across the stack

• Feature parity with BCM5695 multilayer switch

• Low power ~4 W

• Enables system vendors to build scalable high-performance

switches with 10 Gigabit Ethernet support

• Built-in double VLAN tagging enables seamless integration of

enterprise networks and service provider networks.

• Provides hardware support for a number of multicast

applications, such as video and audio conferencing, web

training

• Multiple classes of service (CoS) enable the switch to prioritize

latency-sensitive applications, such as VoIP and video

applications

• Built-in 10 Gigabit Ethernet/XAUI SerDes, in addition to

integrated data and address memory, reduces overall system

cost and design complexity

• 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

TARGET APPLICATIONS

• High performance 10 Gigabit Ethernet multilayer switching

applications targeting the following types of systems:

• Stand-alone systems

• Stackable systems

• Modular chassis systems

• High-end server blades
