This paper is to construct a campus network, and to obtain the existence of ARP virus on campus network defenses. This design USES a VLAN technology and my firewall technology design and defense as ARP virus attacks. The construction of campus network before my existing problems were analyzed, in the construction of hardware when I was analyzed, and take out logic and physical topology, and the network planning, the network cabling, smooth established jining, and puts forward a campus network security operation system dickers jining installation. A network of jining in the defense of ARP forward ARP analysis and the main ARP against three ways, draw the ARP intrusion detection function, and made the network control center and the client to host preventive strategy, the corresponding safety switch configuration, finally established a DHCP server monitoring mode, and puts forward the ideas DHCP deployment of the network, strengthening the defense, reduce the ARP IP network users and drops in conflict. Key words：Network design, the defense of APR 目
