摘　　要：随着以太网交换技术的发展和超大规模集成电路技术的进步,以太网交换芯片功能与性能不断提高。详细介绍了以太网交换芯片BCM56132的内部结构、功能特性、访问方式及2,3层交换的数据流程等,并基于该芯片完成了2、3层交换平台设计,同时对软、硬件实现过程进行了描述,最后通过测试验证了设计的正确性。With the development of ethernet switch technology and super large-scale integrated circuit technology, the fuctions and performance of ethernet switch chips are incresingly improved. A muhilayer switch chip, BCM56132, whose internal architecture, functions and characteristics, access method, layer 2 and 3 switch dataflow, and so on are detailly introduced in this paper. Then the design of layer 2 and 3 switch platform based on BCM56132 is completed. At the same time, the description of the hardware and soft development process is given. Finally, the conclusion indicates that the design is correct.
