  1. would it be fair to say PVID (let say 10) on a port would make a device (Windows 10), where itself (in this case the OS) does not have an VLAN ID, to become set with VLAN10 once it is plugged into the switch port?

  2. I've been trying to make a vlan for a ps5, firestick and pc.
    But as soon as i go take the pvid out of vlan1 the vlan for the pc or firestick losses internet access.. I can't figure it out.. Or I'm i doing it wrong

  3. Just wondering if anybody has seen an animation video that shows the process of what's being done to the packet during the tagging process.. thanks for sharing!

  4. Good start on PVID vs untagged vlans – I've always wondered about that. As you said, I've always set them the same, which seemed like a redundant waste of time, but I would be really interested in some specific use cases with diagrams of where the PVID and the Untag vlan are different values. Thanks for this!

  5. Good video Willie !! ONce people wrap their heads around Vlans they get more comfy 🙂 Also, new to me by accidentally playing around YOu can send untagged vlans over a port over a dumb switch and the vlan aware device will see that traffic.
