3.
If a tagged frame with TPID=0x88A8, it is
forwarded.

If the TPID of tagged frame is not 0x88A8
(ex. 0x8810), it will be discarded.
port will be set to 0x88A8
When an untagged frame is received on a port,
a tag (PVID) is attached and then forwarded.

If a tagged frame with TPID=0x88A8, it is
forwarded.
4.
If the TPID of tagged frame is not 0x88A8
(ex. 0x8810), it will be discarded.
The TIPID of frame transmitted by S-
custom-port will be set to an self-
customized value, which can be set
by the user using the column of
Ethertype for Custom S-ports.
When an untagged frame is received on a port,
a tag (PVID) is attached and then forwarded.
Ingress Filtering:
If Ingress Filtering is enabled and the ingress port is not a member of a VLAN, the frame from the
ingress port is discarded. By default, ingress filtering is disabled.
Ingress Acceptance:
Select the acceptable ingress traffic type on a port.
Tagged and Untagged:
Both tagged and untagged ingress packets are acceptable on a port.
Tagged Only:
Only tagged ingress packets are acceptable on a port. Untagged packets will be dropped.
Untagged Only:
Only untagged ingress packets are acceptable on a port. Tagged packets will be dropped.
Egress Tagging:
The action taken when packets are sent out from a port.
Untag Port VLAN:
Frames that carry PVID will be removed when leaving from a port. Frames with tags other than
PVID will be transmitted with the carried tags.
Tag All:
Frames are transmitted with a tag.
Untag All:
Frames are transmitted without a tag. This option is only available for ports in Hybrid mode.
Allowed VLAN:
Ports in Trunk and Hybrid mode may control which VLANs they are allowed to become members of.
Access ports can only be member of one VLAN, the Access VLAN. By default, a Trunk or Hybrid port will become
member of all VLANs, and is therefore set to 1-4095.
Forbidden VLAN:
A port may be configured to never be member of one or more VLANs. This is particularly useful
when dynamic VLAN protocols like MVRP and GVRP must be prevented from dynamically adding ports to VLANs. The
trick is to mark such VLANs as forbidden on the port in question. By default, the field is left blank, which means that
the port may become a member of all possible VLANs.
4.3.20 GVRP
GVRP (GVRP VLAN Registration Protocol) is defined in the IEEE 802.1Q standard and enables the switch to dynamically
create IEEE 802.1Q compliant VLANs between GVRP-enabled devices. With GVRP, VLAN information can be
automatically propagated from device to device so as to reduce errors when creating VLANs manually and provide
VIDs consistency across network.
This section provides configuration pages for users to set up GVRP timers and enable GVRP on a per-port basis.
