dot1qVlanCurrentUntaggedPorts
Module: Q-BRIDGE-MIB
OID (symbolic): Q-BRIDGE-MIB::dot1qVlanCurrentUntaggedPorts
OID (numeric): 1.3.6.1.2.1.17.7.1.4.2.1.5
Node type: OBJECT-TYPE
Type: PortList
Access: read-only
Description: The set of ports that are transmitting traffic for this VLAN as untagged frames.
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.
