现场在9月7日进行网络切换测试时,对APP-DS和HLW-SW这两组S6520X堆叠环境进行重启切换后出现堆叠口不up问题,后于11月20日凌晨,对XX-B05-N05-OMS-ASW-6520这一组操作尝试复现,重启备设备后复现了堆叠口不up问题。
以11月20日复现的故障现象进行分析,该组设备以49和50口进行堆叠,重启备板slot2后,50口出现不UP问题。

通过以上问题分析可以确认:
1、S6520X设备使用40G电缆进行AP协商时,因AP状态机迁移异常导致堆叠口无法UP,后续将通过软件版本修复。
2、40G光模块UP走的是RxTraing训练方式,不走AP协商流程,可临时选择使用40G光模块规避问题。
