。 Untagging: Ports with untagging enabled will strip the 802.1Q tag from all packets that flow into those ports. If the

packet doesn't have an 802.1Q VLAN tag, the port will not alter the packet. Thus, all packets received by and

forwarded by an untagging port will have no 802.1Q VLAN information. (Remember that the PVID is only used

internally within the Switch). Untagging is used to send packets from an 802.1Q-compliant network device to a

non-compliant network device.
