• High-density value Gigabit Ethernet (GbE) product line, pin compatible to feature GbE BCM56504
• Four 12-Gbps or 10-Gbps HiGig+™ port uplink interfaces
• Four 10-GbE switching ports, CX4 support
• Line-rate switching for all packet sizes and conditions
• On-chip data packet memory and table memory
• IPv6 routing and tunneling
• Advanced Fast Filter Processor (FFP) ContentAware™ classification
• Advanced security features in hardware
• Port trunking and mirroring supported across stack
• Advanced packet flow control:
• Head-of-line blocking prevention
• Back pressure support
• Eight QoS queues per port with hierarchical minimum/maximum shaping per Classes of Service (CoS) per queue per port
• Standard compliant 802.1ad provider bridging
