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).
