LAN1 环路检测，一直提示环路，怎么找到这个MAC？

chyj521

爱快LAN1下建了60多个VLAN，每个vlan给一个公司用，vlan都是自动获取，现在一直提示有回路，但是各个vlan工作正常，没有反应不能上网的情况，怎么找到这个回路的mac？哪位大神遇到过，求解决办法，万分感谢。

楼主您好，爱快中日志只是记录功能 无法追踪到设备，建议还是交换机上开启防环避免环路产生为好

可以看我的贴子

既然你配置了VLAN，为什么报告环路还是 VLAN0

因为所有VLAN的默认MAC地址，和所属物理LAN口的MAC地址是共用一个的，若是其中一个VLAN出现了环路，那么路由器就无法区分具体是哪一个VLAN了，因为所有VLAN都是同一个MAC
解决办法：给每一个VLAN配置一个不同的MAC即可
