4.3.3.6 Private VLAN
The Private VLAN membership configurations for the switch can be monitored and modified here. Private VLANs can be added
or deleted here. Port members of each Private VLAN can be added or removed here.
Private VLANs are based on the source port mask, and there are no connections to VLANs. This means that VLAN IDs and
Private VLAN IDs can be identical.
A port must be a member of both a VLAN and a Private VLAN to be able to forward packets. By default, all ports are VLAN
unaware and members of VLAN 1 and Private VLAN 1.
A VLAN unaware port can only be a member of one VLAN, but it can be a member of multiple Private VLANs. The VLAN Port

on the port. VLAN tagged frames are classified to the VLAN ID in the tag.
If VLAN awareness is disabled, all frames are classified to the Port VLAN ID and
tags are not removed.
Show the ingress filtering for a port. This parameter affects VLAN ingress
processing. If ingress filtering is enabled and the ingress port is not a member of
the classified VLAN of the frame, the frame is discarded.
Shows whether the port accepts all frames or only tagged frames. This
parameter affects VLAN ingress processing. If the port only accepts tagged
frames, untagged frames received on that port are discarded.
Shows the PVID setting for the port.
Shows egress filtering frame status whether tagged or untagged.
Shows UVID (untagged VLAN ID). Port's UVID determines the packet's behavior
at the egress side.
Shows status of Conflicts whether exists or Not. When a Volatile VLAN User
requests to set VLAN membership or VLAN port configuration, the following
conflicts can occur:
Functional Conflicts between feature.
Conflicts due to hardware limitation.
Direct conflict between user modules.
