Layer 3 switch is an important device, which is used in broadband high speed network. A Layer 3 switch refers to a high performance router optimized for the campus LAN or intranet, providing both wire speed Ethernet routing and switching services. Based on the research on layer 3 switch system architecture, A module-based layer 3 crossbar switch design was presented, the layer 3 switch was composed , while has routing, Ether switching, ATM accessing capacity. Then introduced all modules of the GY 302A Layer 3 Switch in detail, expatiated how to test the GY 302A. Finally, the function、performance and EMC of the GY 302A Layer 3 Switch have test. Experimental result show that the GY 302A Layer 3 Switch has been designed successfully.
