12-PORT 10-GBE/HIGIG2™ MULTILAYER SWITCH
FEATURES
SUMMARY OF BENEFITS
• 12 HiGig2™/HiGig+™/HiGig™/10-GbE/1-GbE ports
• Based on StrataXGS® field-proven, robust architecture
• Integrated high-performance SerDes
• Integrated XAUI™ SerDes for all 12 ports
• Uses single SerDes lane per port at GbE speeds
• 144-Gbps switching capacity at line rate
• Support for eight classes of service (CoS) plus two additional
classes for flow control and system management per port
• Support for deficit round robin, weighted round robin, and
strict priority scheduling
• Support for a cut-through switching mode
• Port trunking and remote mirroring support
• Fully integrated data and address memory on a single chip
• Advanced packet flow control
• Head-of-line (HOL) blocking prevention
• Full-duplex flow control (802.3x)
• ContentAware™ network processing per port
• Line rate multifield packet classification
• Supports IEEE 802.1p, type of service (ToS)/DiffServ, rate
limiting, policing, priority tagging, and remapping
• Extended security and ACL filtering
• Full IPv6 routing support
• Enhanced security and management capabilities
• Low power consumption
• High level of integration and low power consumption enable
system vendors to build high-performance, high-port-density
10-Gigabit Ethernet switches in the same form factor as
existing GbE solutions
• Built-in, high-speed serial interfaces with integrated memory
ease and accelerate system design, while reducing cost and
conserving board space
• Built-in Layer 3 routing support enables embedded switch to
become an extension of the enterprise core network
• Advanced load balancing and strong user isolation features
facilitate the implementation of utility computing services
• Integrated security features and enhanced management
capabilities improve network reliability and lower cost of
ownership for BCM56803-based solutions
• Broadcom switch API compatibility enables software reuse
and faster time-to-market
APPLICATIONS
• Embedded switch in next-generation 10-GbE blade servers
• 10-GbE/1-GbE switching engine in Advanced TCA chassis
platforms
• Multilayer switch in high-density 10-GbE switches
