Tertiary institutions have been set up their own campus network. Internet technology and modern education as well as the rapid development of ever closer integration of the campus network allow the school of education, teaching and research as an important platform. Campus LAN with other enterprises and institutions of the local area, Computer networking and Internet user groups is more complicated. There are teachers preparing lessons, students in the engine room, dormitory, library, as well as personnel, finance, logistics and other administrative office computer, and so on. Different users have different needs of the network for its own information security requirements, which can be divided into a number of campus network VLAN. VLAN is a logic network of end to end which adopted administrative software to construct and can crossover different location. In the paper explained the important concepts of VLAN、technique research and the implement method in detail.
