摘　　要：动态主机配置协议(DHCP)主要用来给网络上的主机动态提供配置参数。为了减少因采用DHCP服务器给网络带来的不安全性,分析了DHCP服务器在校园网应用中存在的问题。针对以上问题产生的机制,结合网络安全技术,提出了DHCP结合动态VLAN、DHCP嗅探、动态ARP检测技术的解决方案,并结合实际阐述了该方案的具体实现方法。Dynamic host configuration protocol （DHCP） provides the configuration parameters for network hosts. In order to reduce the insecurities brought by DHCP server in network, the problems of DHCP server in its application in campus LAN are analyzed. Based on the reasons for these problems and the technology of network security, a solution combining DHCP, Dynamic VLAN, DHCP Snooping and Dynamic ARP Inspection is advanced. At last, the realization of this solution is explained.
