with the VLAN tags. All tags use EtherType 0x8100 or 0x88A8, where 0x8100 is used for customer tags and 0x88A8 are used
for service provider tags.
In cases where a given service VLAN only has two member ports on the switch, the learning can be disabled for the particular
VLAN and can therefore rely on flooding as the forwarding mechanism between the two ports. This way, the MAC table
requirements is reduced.

Description
Select port number for this drop down list to set VLAN port setting.
Set the port in access, trunk, hybrid, tunnel mode.

Trunk means the port allows traffic of multiple VLAN.

Access indicates the port belongs to one VLAN only.

Hybrid means the port allows the traffic of multi-VLANs to pass with tag
or untag mode.

Tunnel configures IEEE 802.1Q tunneling for a downlink port to another
device within the customer network.
Allow assign PVID for selected port.
The PVID will be inserted into all untagged frames entering the ingress port. The
PVID must as same as the VLAN ID that the port belong to VLAN group, or the
untagged traffic will be dropped.
The range for the PVID is 1-4094.
Determines 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 the port are discarded.
Options:

All

Tag Only

Untag Only
By default, the field is set to All.
 If ingress filtering is enabled (checkbox is checked), frames classified to a
VLAN that the port is not a member of get discarded.
