9.3 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.
The following figure describes VLAN Trunking. 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

Type
You may choose to accept both tagged and
