对于 DSW-A, 问题应该是在对端 server,LACP 设置可能有 misconfiguration.

1. LACP PDU 对于 nexus,有去无回,协商有问题,所以在 individual 状态,不在 port-channel
DSW-A# sh lacp interface e123/1/26
Interface Ethernet123/1/26 is individual <<<<<
  Channel group is 1525 port channel is Po1525
  PDUs sent: 869634
  PDUs rcvd: 0 <<<<

2. LACP PDU 的状态,其中对端的 Ag-0 字段异常,应该是 Ag-1,表示可以聚合

Local
Actor Oper State=(Ac-1:To-0:Ag-1:Sy-1:Co-1i-1e-1:Ex-0)

Partner
Partner Oper State=(Ac-0:To-0:Ag-0:Sy-0:Co-0i-0e-0:Ex-0)
3. 可以参考之前我给客户的回复


对于 DSW-B, 可以先删除 port-channel 配置,观察物理口是否能up

最后建议,开 TAC case,让 TAC online 看一下
