BCM56502数据手册Broadcom中文资料规格书

描述 Description

The BCM56502 is the fifth generation of the highly-integrated and cost effective StrataSwitch and StrataXGS product line and is a single-chip solution with 24 GbE ports and two 10 GbE/HiGig+ uplink ports.
The BCM56502 incorporates 24 GbE ports that can operate at 10⁄100⁄1000 Mbps. The uplink ports can operate in two modes: 10 GbE switching mode and HiGig+ uplink mode. The integrated 10 GbE switching ports are CX-4 compliant XAUI interfaces. The HiGig+ uplink interface is used to connect to other StrataXGS devices in a larger stacking system or to the BCM5675/BCM5676 Switch Fabric via a backplane in a multislot redundant chassis system.FEATURES
• 24 10/100/1000 Mbps Ethernet ports supporting both copper and fiber connections

• Two 12 Gbps or 10 Gbps HiGig+™ port uplink interfaces
• Two 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:
