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.
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).
Refer to the following figure for an illustrated example.
Users can combine a number of VLAN ports together to create VLAN trunks.
