二、解决办法：
1.检查设备光模块发光是否正常；
如果设备光模块发光正常的话，那让传输局检查光缆，工程队检查尾纤和法兰头。
2.如果是端口误码太多，将物理端口shutdown，然后再noshutdown试试。
如果不行的话只能更换一个物理网口了。
三、基站瞬断故障排查：
1.登录到瞬断的设备上，一般成环的节点很少会出现瞬断，但是不排除。
首先检查瞬断节点的收发光功率，如果没问题就逐条检查环上的其他节点的光功率。
一般情况下是光口实际收光超出临界值；
2.检查设备温度，看风扇状态：
a.设备温度过高会导致板卡假死，当温度降到板卡可以承受的温度的时候，板卡又会起来，所以就会出现瞬断。
b.查看指令如下：
查看风扇状态，Type表示设备型号。
正常状态下3个LED是OFF状态，即没有告警，如果高温的话CriticalLEDstate和MajorLEDstate会变成RED。
另外就是观察风扇状态，FanInformation，下面的是正常的风扇状态，如果不正常的话，Status会变成failed。
