摘　　要：随着互联网的不断深化应用,我校机房也接入了互联网,然而也给机房管理带来了许多问题。特别是由于管理维护以及其他人为原因经常会出现IP地址冲突的现象。DHCP技术避免了因手工配置IP地址及子网掩码产生的错误,同时也避免了因把同一个地址分配给多个用户而产生的地址冲突。同时也降低了IP地址的配置管理。使用DHCP服务使得配置或者重新配置网络中的工作站变的更加方便。通过对DHCP服务的配置,还能够灵活的设置IP地址的租期。然而采用传统的操作系统+服务器。不论使用哪一种操作系统,都需要另外使用一台服务器来安装,增加网络建设投资。目前比较理想的方案是直接使用三层交换机的DHCP功能,即节省投资,又能达到预期的目的。本文分析动态主机配置协议的工作原理,描述在三层交换机上DHCP服务器的配置,并提出如何禁止非法DHCP服务器的方法。With the continuous deepening of the Internet application, our school computer room is also connected to the Internet, but it also brings many problems to the management of the computer room. In particular, IP address conflicts often occur due to management maintenance and other man-made reasons. DHCP technology avoids errors caused by manually configuring IP addresses and subnet masks, and also avoids address conflicts that occur when the same address is assigned to multiple users. At the same time, it also reduces the configuration management of IP addresses. Using DHCP services makes it easier to configure or reconfigure workstations in the network. Through the configuration of the DHCP service, it is also possible to flexibly set the lease term of the IP address. However, the traditional operating system ＋ server is used. Regardless of which operating system is used, it is necessary to use another server to install and increase network construction investment. At present, the ideal solution is to use the DHCP function of the three-layer switch directly, that is, to save investment and achieve the desired purpose. This paper analyzes the working principle of dynamic host configuration protocol, describes the configuration of DHCP server on the three-layer switch, and proposes how to prohibit illegal DHCP server.
