利用VLAN技术改善校园网IP地址管理

Improvement of IP Address Management for Campus Network by VLAN

VLAN技术可以将一个大的网络划分为若干小的子网 ,并且限制各子网间的相互访问。利用VLAN ,可以提高网络的管理水平 ,减少网络内部各部分的通信量 ,加强网络的安全性。本文以四川工业学院校园网络为例介绍如何利用CISCO系列交换机和路由器规划和配置VLAN ,以及利用VLAN特性改善和加强校园网络的域管理水平。

Virtual Local Area Network(VLAN)can partition a large scale of network into many segments,and restrict accessment from one segment to another.Using VLAN,we can improve management of the network;reduce inter segment traffic and enhance security of the network.This paper introduces how to plan and configure VLAN with Cisco Switches and Routers of the Campus Network,Sichuan University of Science and Technology.With VLAN feature,the domain management of th campus network is greatly improved and enhanced.
