Brief

SUMMARY OF BENEFITS

•

High level of integration and low power consumption enable

high-performance, high-port density 10-GbE in the same form

factor as 1-GbE solutions.

12 X 10-GBE + 8 X HG[16] + 4 X 1-GBE MULTILAYER ETHERNET SWITCH

FEATURES

•

Provides 12 10-Gigabit Ethernet (10-GbE) ports + 8 HG[16] ports

+ four 1-GbE ports; each of the HG/10-GbE ports can also support

1 GbE, 2.5 GbE, or 10 GbE, as well as HiGig™/HiGig2™

protocols.

•

Line rate full-duplex switching for 252+ Gbps.

•

Built-in Layer 2 (L2), VLAN, and Layer 3 (L3) tables with 10

Quality of Service (QoS) queues per port.

•

Intelligent Traffic Management with SAFC supports storage,

HPC, video, voice, and data over unified 10-GbE fabric enabling

convergence in the data center.

industry-leading 10-GbE port density empower next-generation

Enterprise aggregation and data center applications.

•

Multistage ingress and egress ContentAware™ Engine for deep

packet inspection and classification provides flexible ingress and

egress Access Control Lists (ACL), IPv4/v6 µflow, proprietary

headers, and multi-tuple lookups, all at line rate.

•

Advanced load balancing, fast hardware failover and recovery

(< 10

μs),

and ultralow latency (< 1

μs)

provide high

performance, scalable, and reliable solutions for High

Performance Computing (HPC) environments.

•

IPv4 and IPv6 Virtual Routing with full support for L2/L3 tunnels

(Generic Routing Encapsulation [GRE], IPv4 over IPv6, IPv6 over

IPv4, Queue in Queue [QinQ], 802.1ah)

•

Robust integrated SerDes, on-chip packet buffer memory, and

PLLs accelerate system design and drastically reduce cost and

conserve board space.

•

Intelligent scheduler supports Strict Priority (SP), Weighted

Round Robin (WRR), and Deficit Round Robin (DRR) with built-

in Weighted Random Early Discard (WRED) and Explicit

Congestion Notification (ECN) for congestion avoidance.

(SAFC) mechanism allows in-band backpressure per Class of

Service (CoS).

•

Sixth-generation HiGig/HiGig2 stacking technology facilitates

full-speed upgrade while maintaining compatibility with existing

deployed switches.

Development Kit (SDK) enable software reuse from existing

deployed systems and faster time-to-market.

•

IEEE 802.3™ Link Pause and Service Aware Flow Control™

•

Fully compatible Broadcom software API and Software

•

Full support for tricolor marking and metering with policing on

ingress and egress separately (RFC-2698 and MEF).
