all ports are tagged, except for one port that can be
untagged.
General

screen allows you to select the VLAN
for the port selected and determine whether it is tagged
or untagged. It will be displayed with a T if it is tagged and
with a U if it is untagged.

VLAN Management > GVRP
GARP VLAN Registration Protocol (GVRP) is specifically
provided for automatic distribution of VLAN membership
information among VLAN-aware bridges. GVRP allows
VLAN-aware bridges to automatically learn VLANs to
bridge ports mapping, without having to individually
configure each bridge and register VLAN membership.
VLAN Management > GVRP
