图26 根据上面的分析,根桥SW1的G1/0/1之所以出现Dispute保护,总结起来就是两个字“单通”:SW3不知道SW1的存在(收不到SW1的BPDU报文),而SW1知道SW3存在且受到了SW3发来的非正常BPDU报文(Flag字段中F=0,L=1)。 知道了原因,解决方法就是打破“单通”,让SW1和SW3的BPDU报文能够被正常的相互接收,及在S...

您好: Dispute 触发,是由于bpdu 单通造成,上游设备收到下游设备低优先级的bpdu,而下游设备收不到上游设备发出的高优先级BPDU; 对于设备全局未启用stp,可能是B交换机的下游设备发出; 由于B设备全局未启用stp,B设备收到BPDU报文,会按照普通业务报文处理,受到互联接口vlan trunk 及PVID 配置的影响;造成bpdu单通; 对于...
