Tag All
All frames, whether classified to the Port VLAN or not, are transmitted with a tag.
Untag All
All frames, whether classified to the Port VLAN or not, are transmitted without a tag.
This option is only available for ports in Hybrid mode.
Allowed VLANs :
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.
The field's syntax is identical to the syntax used in the Existing VLANs field. By default, a port may
become member of all possible VLANs, and is therefore set to 1-4095.
The field may be left empty, which means that the port will not be member of any of the existing
VLANs, but if it is configured for VLAN Trunking it will still be able to carry all unknown VLANs.
Forbidden VLANs :
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. The syntax is identical to the
syntax used in the Existing VLANs field.
By default, the field is left blank, which means that the port may become a member of all possible
VLANs.
