we encounter a question,pls thank for your assistant!
dual 93180 with vPC,they portchannel to huawei switch,globally enable bpduguard default on 93180,and configured edge port。
we found out that all of ports within portchannel changed down(channel errdisable)with huawei sent bpdu to one of cisco port。
why all of port of portchannel would be down,although only one of them received bpdu from huawei?is vPC sync mechanism ? because i think it should be down only one。
thanks a lot for your helps!
