通过交换机检测解决网络环路的探索

Exploration of solving network loop by switch detection

文章对网络环路产生的原因进行了分析。网卡或网络设备损坏、网络环路、网络病毒都可能产生广播风暴。广播风暴和MAC地址飘移是网络环路的表现之一。文章列举了二层环路的几种情况并提出了解决环路问题的方案,通过启用环路保护功能,开启端口环路监测功能,利用抓包软件和查看端口状态能快速准确定位到故障交换机端口,从而快速地解决环路问题,为排除网络故障提供帮助。

The network loop analysis,damage of network card,network loop,network virus may produce broadcast storm,broadcast storm and MAC address drift is one of the performance of the network loop.The paper proposes loop solution,by enabling loop protection function and opening port loop monitoring function.Using package software and view port status can quickly and accurately locate the fault switch port,so as to quickly solve the loop problem,to help eliminate network fault.
