7.1.3 Port VLAN Trunking
Enable VLAN Trunking 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. Suppose you want to create VLAN groups 1 and 2 (V1 and V2) on devices A and B.
Without VLAN Trunking, you must 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 Trunking 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).
7.1.4 Select VLAN Type
