Description
Ingress
Acceptance
Hybrid ports allow for changing the type of frames that are accepted on ingress.
Tagged and Untagged
Both tagged and untagged frames are accepted. See Port Type for a description of
when a frame is considered tagged.
Tagged Only
Only frames tagged with the corresponding Port Type tag are accepted on ingress.
Untagged Only
Only untagged frames are accepted on ingress. See Port Typefor a description of when
a frame is considered untagged.
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 become 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.
