问题描述：
S5130S-52S-SI 两台交换机做成堆叠后，两个之间的一个端口配置成聚合口后，网络不通？两台交换机各一个端口配置成
interface Bridge-Aggregation1 后 两根网线插上去后网络不通，但是管理vlan 是通的，业务vlan不通，如果拔掉一根网络又正常使用的？请问是否有环路情况，如何查看？还是交换机的堆叠（IRF配置）没有配置好？

最佳答案
display link-agg verbose看一下物理接口是不是都是S状态，S状态说明聚合已经成功，使用聚合接口互联无问题
display IRF看有多台设备说明IRF已经成功的

这个聚合状态只有一根线吗？没有看到两根线诶
正常不接线，只要成员接口在聚合口里，也会显示一个S一个U的，是聚合有问题不

成功的

您好，请知：
关于IRF后聚合不通的问题，以下是排查要点，请参考：
1、聚合不成功可能会带来环路而影响业务。
2、检查两端链路聚合的模式是否一致。
3、检查两端链路聚合组透传的配置是否一致。
4、检查物理成员端口的配置和链路聚合组的配置是否一致。
5、可以dis link-agg verbose检查聚合组的状态是否为S。
