-

Forbidden—The interface is not allowed to join the VLAN even from 
GVRP registration. When a port is not a member of any other VLAN, 
enabling this option on the port makes the port part of internal VLAN 
4095 (a reserved VID). 

-

Excluded—The interface is currently not a member of the VLAN. This is 
the default for all the ports and LAGs. The port can join the VLAN through 
GVRP registration

-

Tagged—Select whether the port is tagged. This is not relevant for 
Access ports.

-

Untagged—Select whether port is untagged. This is not relevant for 
Access ports.

-

PVID—Port PVID is set to this VLAN. If the interface is in access mode or 
trunk mode, the device automatically makes the interface an untagged 
member of the VLAN. If the interface is in general mode, you must 
manually configure VLAN membership. 

Click Apply. The settings are modified and written to the Running Configuration 
file.

To see the administrative and operational VLANs on an interface, click Details.

Adjacent VLAN-aware devices can exchange VLAN information with each other 
by using the Generic VLAN Registration Protocol (GVRP). GVRP is based on the 
Generic Attribute Registration Protocol (GARP) and propagates VLAN information 
throughout a bridged network.

Since GVRP requires support for tagging, the port must be configured in Trunk or 
General mode. 

When a port joins a VLAN by using GVRP, it is added to the VLAN as a dynamic 
member, unless this was expressly forbidden in the Port VLAN Membership page. 
If the VLAN does not exist, it is dynamically created when Dynamic VLAN creation 
is enabled for this port (in the GVRP Settings page).
