9.1.2.2 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).

DESCRIPTION
Permanent VLAN This is a static VLAN created manually.
Dynamic VLAN This is a VLAN configured by a GVRP registration/deregistration
process.
Registration Fixed Fixed registration ports are permanent VLAN members.
Registration Ports with registration forbidden are forbidden to join the
Forbidden specified VLAN.
Normal Registration Ports dynamically join a VLAN using GVRP.
Tagged Ports belonging to the specified VLAN tag all outgoing frames
transmitted.
Untagged Ports belonging to the specified VLAN don't tag all outgoing
frames transmitted.
Port VID This is the VLAN ID assigned to untagged frames that this port
received.
Acceptable Frame You may choose to accept both tagged and untagged incoming
Type frames, just tagged incoming frames or just untagged incoming
frames on a port.
Ingress filtering If set, the Switch discards incoming frames for VLANs that do not
have this port as a member
