This is useful in scenarios where a cloud of intermediary switches must bridge VLANs that
haven't been created. By configuring the ports that connect the cloud of switches as trunking
ports, they can seemlessly carry those VLANs from one end to the other.
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.
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 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.
