If a port is not VLAN aware, all frames are assigned to the default VLAN (as specified by
the Port VLAN ID) and tags are not removed.
If a port is VLAN aware, each frame is assigned to the VLAN indicated in the VLAN tag,
and the tag is removed.
◆ Ingress Filtering – If ingress filtering is enabled and the ingress port is not a member of the
classified VLAN of the frame, the frame is discarded.
◆ Frame Type – Shows whether the port accepts all frames or only tagged frames. If the
port only accepts tagged frames, untagged frames received on that port are discarded.
◆ Tx Tag – Shows egress filtering fame status, indicating whether frames are transmitted as
tagged or untagged.
◆ UVID – Shows the untagged VLAN ID. A port's UVID determines the packet's behavior at
the egress side. If the VID of Ethernet frames leaving a port match the UVID, these frames
will be sent untagged.
◆ Conflicts – Shows whether conflicts exist or not. When a software module requests to set
VLAN membership or VLAN port configuration, the following conflicts can occur:
■ Funtional conflicts between features.
■ Conflicts due to hardware limitations.
■ Direct conflicts between user modules.
