这边有一台9200交换机,最近接口一直在频繁的UP DONW,日志也没有看到关于生成树环路什么的信息,就是接口down up. 应该要怎么排查问题,其他交换机都是正常的,同样接的PC,其他交换机则没有问题。麻烦大家帮我分析一下, 下面附日志

可以看看是不是中了这个bug,感觉现象差不太多

https://bst.cisco.com/bugsearch/bug/CSCvw87631

 

嗯嗯,看里面的意思是要把接口限速100Mb, 我试了一下,我这个是48口交换机。大部分都正常了,还有几个接口还是在UP DOWN,另外一台有相同问题的交换机也配置了,但是没有效果,真的是奇怪

如果按照bug的条件已经确定是该问题,那么建议找个修复版本升级一下试试吧,修改速率也不是根本解决办法
