Tagged Only
Only tagged frames are accepted on ingress. Untagged frames are discarded.
Untagged Only
Only untagged frames are accepted on ingress. Tagged frames are discarded.
Egress Tagging
Ports in Trunk and Hybrid mode may control the tagging of frames on egress.
Untag Port VLAN
Frames classified to the Port VLAN are transmitted untagged. Other frames are
transmitted with the relevant tag.
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 Enabled VLANs field. By
default, a Trunk or Hybrid port will become member of all VLANs, and is therefore set
to 1-4095.
The field may be left empty, which means that the port will not become member of any
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 Enabled VLANs field.
By default, the field is left blank, which means that the port may become a member of
all possible VLANs.
