VLAN Trunk Settings

Enable VLAN on a port to allow frames belonging to unknown VLAN groups to pass through that port. This is useful if you want
to set up VLAN groups on end devices without having to configure the same VLAN groups on intermediary devices.
Refer to the following figure for an illustrated example. Suppose you want to create VLAN groups 1 and 2 (V1 and V2) on
devices A and B. Without a VLAN Trunk, you must first configure VLAN groups 1 and 2 on all intermediary switches C, D and
E; otherwise they will drop frames with unknown VLAN group tags. However, with VLAN Trunk enabled on a port(s) in each
intermediary switch, you only need to create VLAN groups in the end devices (A and B). C, D and E automatically allow frames
with VLAN group tags 1 and 2 (VLAN groups that are unknown to those switches) to pass through their VLAN trunking port(s).
Users can combine a number of VLAN ports together to create VLAN trunks. To create VLAN Trunk Port settings on the Switch,
select the ports to be configured, change the VLAN Trunk Global State to Enabled, and click Apply, the new settings will appear
in the VLAN Trunk Settings table in the lower part of the window.
