基于Cisco模拟器的动态主机网络信息配置案例设计与实现

Design and implementation of dynamic host network information configuration case based on Cisco simulator

随着计算机网络规模的不断扩大,网络结构复杂度也相对提高。在大型网络中,要确保所有主机都拥有合法的IP地址是一件相当困难的管理任务。手动配置需要花费较长时间,而配置过程中产生的错误可能导致主机之间无法进行正常通信。文章首先介绍动态主机配置协议的基本概念;其次借助Cisco模拟器搭建网络拓扑结构,对交换机、路由器等网络设备进行配置;最后让主机自动获取IP信息,通过网络相关测试,达到令人满意的预期效果。

With the continuous expansion of computer network scale,the complexity of network structure is also relatively improved.In a large network,it is a very difficult management task to ensure that all hosts have legal IP addresses.Manual configuration takes a long time,and errors generated during the configuration process may cause normal communication between hosts.This paper first introduces the basic concept of dynamic host configuration protocol,and then uses Cisco simulator to build network topology,configure switches,routers and other network devices,and finally let the host automatically obtain IP information to achieve satisfactory expected results through network-related tests.
