摘　　要：要确认星型结构的以太网所构建的校园网中众多的交换以及它们之间的光连接线路运行是否正常,往往通过查看基于SNMP的网管软件或者采用单一的测试方法解决,但这些方法并不能很好满足运行管理的要求。在分析了校园以太网络的连接方式和运行特征的基础上,建立了光连接线路和网络交换形成的单链表数据模型。通过对所有处于管理VLAN所在区域的交换机接口IP进行自动Ping探测以及TraceRt探测,并与开源MRTG软件获得的流量进行对比分析,实现了对光线路以至两端物理设备运行状态的判断。To check the connection between a large number of switchings and the optical lines in working order,the network management software based on SNMP protocol is usually checked,or a single test method is used.However,these methods cannot meet the requirements of the operation and management very well.This paper analyzes the features of campus ethernet connection and operation and establishes the singly linked list modal.Finally,it achieves the automatic detection the operation state between the optical line and switch equipment in management vlan regions based on Ping or TraceRt method and makes a comparison with open source MRTG software＇s flow.
