These settings compose one ingress port Default Tag. This tag is used when a tag insertion is required
for untagged packets.
802.1Q Filtering
802.1Q VID Filtering function allows to admit or reject certain VID tagged packets. Up to 16 allowed
(positive list) or rejected (negative list) VIDs can be configured. This function allows to limit certain
packets to pass from one link segment to another one.
[VID Table] options
Disable - 802.1Q VID filtering is disabled.
Allowed VID - Only the VLAN-tagged packets with VIDs in VID table are admitted.
Rejected VID - The VLAN-tagged packets with VIDs in VID table are rejected and dropped.
For untagged and priority-tagged packets, the ingress [Default Tag - VID], also called PVID is used for
VID filtering. If it is in Allowed VID table, the untagged packet is allowed to pass; otherwise, dropped.
If it is in Rejected VID table, the untagged packet is dropped.
