问题描述：
接了线到S5120上的2/0/27后，交换机报出如下日志：
2/0/27 是access vlan 500，我把原先在1/0/25（trunk permit all）的线拔下来了，接到了2/0/27，然后所有聚合口都down，对端思科交换机的接口errdisable。

最佳答案
检查下堆叠聚合的配置吧

聚合配置如下 <sd-cn-sia-003>dis cur int GigabitEthernet 1/0/8 # interface GigabitEthernet1/0/8 port link-type trunk undo port trunk permit vlan 1 port trunk permit vlan 2 to 4094 mirroring-group 1 mirroring-port both port link-aggregation group 8 # return <sd-cn-sia-003>dis cur int GigabitEthernet 2/0/8 # interface GigabitEthernet2/0/8 port link-type trunk undo port trunk permit vlan 1 port trunk permit vlan 2 to 4094 mirroring-group 2 mirroring-port both port link-aggregation group 8 # return <sd-cn-sia-dis cur int br <sd-cn-sia-003>dis cur int Bridge-Aggregation 8 # interface Bridge-Aggregation8 port link-type trunk undo port trunk permit vlan 1 port trunk permit vlan 2 to 4094 link-aggregation mode dynamic # return 配置我感觉没问题，关键是为什么vlan不匹配，就会导致这个问题
