7.3 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 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).

7.5 802.1Q Static VLAN
Make sure 802.1Q is selected in the Basic Setting > Switch Setup screen.
Use a static VLAN to decide whether an incoming frame on a port should be
• sent to a VLAN group as normal depending on its VLAN tag.
• sent to a group whether it has a VLAN tag or not.
• blocked from a VLAN group regardless of its VLAN tag.
You can also tag all outgoing frames (that were previously untagged) from a port with the specified
VID.
