两台68做M-lag,下联思科的9200,每天不固定的会出现备机下联口协议down然后又up(主设备是正常的)。检查过配置,线路、模块等都没问题。log buffer如下,这表明是思科交换机的问题吗?那边没有回复报文?需要再从那些方向排查解决呢?

您好,物理上没有down 都是协议上在down,所以不是链路的问题,是lacp报文问题, because the peer port did not have the Synchronization flag.对端发的报文异常导致端口无法选中

同时开2个case
一个开给思科
一个开给H3C

您认为是哪边的问题呢?我查询日志处理建议是检查对端发送的LACPDU。

那是需要去排查思科测交换机的问题对吗?
