现场有一台华三的Mer5200路由器,现象是断电前网线接上去之后通电开机,配置后使用都正常。但只要换LAN口的话就立刻断线,无论设置成自动获取IP和手动设置IP都无法连接。在Windows系统的网卡状态有发送数据包,但接收数据包一直为0,必须把路由器重启之后才能连接,但LAN口一换就又断了。还有一个现象就是只要一换网口的话,除了WAN口正常外其他网口指示灯都会灭了,等1-2秒才又亮起来,就全部设备都断线了。已经更新到最新的固件还是一样。最新的固件是MER5200-CMW710-R0821P16。故障还是一样。就算是恢复出厂设置都也一样。查看系统日志没提示什么故障。麻烦大家看看是什么问题哈,谢谢!

可以尝试路由器的两个lan口接电脑,然后将其中的一台电脑进行更换lan口的操作,看看会不会有这种情况,如果这样测试是正常的话,就要排查内网问题了。但是如果这样测试也会出现一样的情况,建议在故障发生时收集路由器的诊断信息,联系400售后工程师。

可以尝试尝试故障时,关闭路由器lan口物理状态再打开,然后将端口模式改为全双工,电脑的网卡禁用启用一下
