  • 交换机Vlan中 tagged和untagged的区别 - 知乎
    pvid是交换机一个端口上的id，一个端口只能有一个pvid，多个端口可以有相同的pvid。 Untagged: 不管收到的数据帧是否已经有VLAN标记，将数据帧中的vlan标记修改为自己的pvid。 Tagged：收到的数据帧没有vlan标记时将数据帧中的vlan标记修改为自己的pvid；如果收到的数据帧上有vlan标记时不做修改。 Untagged：若数据帧中的VID与端口的PVID相等，则“ 去标签 ”并 转发 该帧；否则丢弃。 好像只有一些小型交换机将 VLAN 端口分为tagged和untagged。 企业级的交换机都是按照accrss trunk hybird 划分的。 看了前面的回答，有不少答主的答案互相矛盾。 补充一点：

  • Omada understanding untagged and tagged on Port - Reddit
    Whilst untagged means drop the tag at this port because the device on this port can't speak tagged traffic This is just a little simpler than it really is due to needing to set pvid on untagged ports so they speak vlan on the way out of the port so anything that speaks vlan knows that port belongs to a specific one
