请高手帮我看看这个光纤线路的故障怎么处理
问题是这样的:我们市机房到县机房同时有联通和电信两条光纤同时传输数据.但是最近出现很多客户反映慢,办理业务提交后画面定住不动.我查看端口发现电信光纤的s口不正常出现如下显示:

而联通线路正常,将电信的s口做shutdown后数据全部走联通,业务办理正常.
而且我发现:将电信光纤线路物理设备关闭后马上打开,或者对电信s口做shutdown和undo shutdown后线路立即恢复正常无错误的crc校验,无冲突,无丢包.但是好不了几天又出现同样的问题,而且一天比一天严重.反复如此.最后只好将电信端口shutdown处理了.
对端市机房路由器该县端口显示如下:(其他县子接口均正常)

求教:问题断开线路后马上就恢复正常,后又反复出现且日渐严重?市里到其他县均正常可以说明问题大概是出现在该县机房而不是市机房吗?是和跳线有关吗?
请高手解答,不胜感激.
