Operation:
Outgoing packets (from the gateway to the switch):
All outgoing packets are tagged, each according to its interface (control, media or
OAM). If the gateway's native ID is identical to one of the other IDs (usually to the
OAM ID), this ID (e.g., OAM) is set to zero on outgoing packets
(VlanSendNonTaggedOnNative set to 0). This method is called Priority Tagging (p tag
without Q tag). If the parameter VlanSendNonTaggedOnNative is set to 1, the
gateway sends regular packets (with no VLAN tag).
Incoming packets (from the switch to the gateway):
The switch sends all packets intended for the gateway (according to the switch's
configuration) to the gateway without altering them. For packets whose VLAN ID is
identical to the switch's PVID. In this case, the switch removes the tag and sends a
packet.
The gateway only accepts packets that have a VLAN ID identical to one of its interfaces
(control, media or OAM). Packets with a VLAN ID that is 0 or packets without a tag are
accepted only if the gateway's native VLAN ID is identical to the VLAN ID of one of its
interfaces. In this case, the packets are sent to the relevant interface. All other packets are
rejected.
