组网如下:
DCGW1和DCGW2分别以三层聚合与下方DRNI中的二层聚合互联,右侧DCGW2——S-EOR2的RAGG11——BAGG4中始终有三个接口是未选中的状态;将三个接口踢出聚合口能正常双up;
EOR-2的HGE3/0/34、3/0/35、3/0/36,RT2的HGE 3/0/3、4/0/4、5/0/4
接口down皆为
Current state: UP
Line protocol state: DOWN(LAGG)
左侧的DCGW1(RT1)——S-EOR1的链路聚合都是正常的。

交换机诊断中看到有如下BDPU保护日志,看聚合口4配置,配置了stp edged-port,且为边缘端口,同时查看设备stp 发现已开启BPDU-Protection功能,同时本设备为根桥设备,网络拓扑稳定的情况下,根桥设备是不会收到网桥设备发过来的TC BPDU报文,如果根桥设备持续收到TC BPDU报文,说明网络拓扑一直处于不稳定状态,即根桥的边缘端口收到BPDU报文后,引起的端口持续震荡和网络拓扑不收敛。

1、EOR-2设备底层端口被block了,原因是聚合口使能stp,聚合成员有选中变化,导致聚合成员有block或者unblock的操作,stp和lag线程均会操作端口的block状态,可以通过shutdown/undo shutdown 端口恢复。 聚合口震荡时间和底层block记录一致。
