What is dot1qVlanCurrentUntaggedPorts?
This is a byte string showing which ports on this VLAN send frames without VLAN tags (raw frames, not tagged with VLAN ID). Engineers use this to identify which ports are configured to strip VLAN tags before forwarding to end devices that don't understand VLAN headers. For example, port 2 might be untagged for VLAN 100 if a desktop PC connects there.
