问题描述：
两台5560交换机作为核心交换机，X1/0/25和X2/0/25组成了一个链路，最近X1/0/25频繁出现down的情况，导致一个区域不能正常访问，怎么解决？

最佳答案
接口出现频繁down，有以下情况：
1、线路故障，建议替换测试；
2、设备生成树频繁收敛，建议排查TC来源（设备上会有日志提示从哪探测到拓扑变更）

正常来说会激活x2/0/25，现在也没有激活起来
现场做的是动态聚合吗？如果是动态聚合需要两端都做成一样的
做的是静态聚合
静态聚合另一个口不应该起不来，应该是这个接口本来就有问题吧。光口吗？检查下链路是否正常。
光口来的，一个是未亮，一个是橙色灯
没亮的接口就没有起来，查查链路和收发光吧
