 Frame Type 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.
 Port VLAN ID Shows the PVID setting for the port.
 Tx Tag Shows egress filtering frame status whether tagged or untagged.
 Untagged VLAN ID 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.
 Direct conflict between user modules.

4.6.6 Port Isolation
Overview
When a VLAN is configured to be a private VLAN, communication between ports within that VLAN can be prevented. Two
application examples are provided in this section:
 Customers connected to an ISP can be members of the same VLAN, but they are not allowed to communicate with each
other within that VLAN.
 Servers in a farm of web servers in a Demilitarized Zone (DMZ) are allowed to communicate with the outside world and
with database servers on the inside segment, but are not allowed to communicate with each other
