The page includes the following fields:
Object
Description
Port
The logical port for the settings contained in the same row.
Port VLAN ID
Shows the VLAN identifier for that port. The allowed values are 1
through 4095. The default value is 1.
Port Type
Shows the Port Type. Port type can be any of Unaware, C-port, S-
port, Custom S-port. If Port Type is Unaware, all frames are classified
to the Port VLAN ID and tags are not removed. C-port is Customer
Port. S-port is Service port. Custom S-port is S-port with Custom
TPID.
Ingress Filtering
Shows 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.
Frame Type
Shows if 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.
Tx Tag
Shows egress filtering frame status whether tagged or untagged.
UVID
Shows UVID (untagged VLAN ID). Port's UVID determines the
packet's behavior at the egress side.
Conflicts
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.

Private VLAN
The Private VLAN Membership Configuration page allows you to configure private
VLAN membership. The private VLAN membership configurations for the switch can be
monitored and modified here; private VLANs and private VLAN port members can be
added or deleted 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 are 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.
