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
D and E; otherwise they will drop frames with unknown VLAN group tags. However, with
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).

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