BCM56821 Brief ® 12 X 10-GBE + 8 X HG[16] + 4 X 1-GBE MULTILAYER ETHERNET SWITCH FEATURES SUMMARY OF BENEFITS • Provides 12 10-Gigabit Ethernet (10-GbE) ports + 8 HG[16] ports • High level of integration and low power consumption enable + 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. high-performance, high-port density 10-GbE in the same form factor as 1-GbE solutions. • 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. • L o w p o w e r , s up e r i o r E nt e r p r i s e c l a s s f e a t ur e s , a nd 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 • Intelligent scheduler supports Strict Priority (SP), Weighted PLLs accelerate system design and drastically reduce cost and conserve board space. Round Robin (WRR), and Deficit Round Robin (DRR) with builtin Weighted Random Early Discard (WRED) and Explicit Congestion Notification (ECN) for congestion avoidance. • IEEE 802.3™ Link Pause and Service Aware Flow Control™ (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. • Fully compatible Broadcom software API and Software Development Kit (SDK) enable software reuse from existing deployed systems and faster time-to-market. • Full support for tricolor marking and metering with policing on ingress and egress separately (RFC-2698 and MEF).
