When a port joins a VLAN by using GVRP, it is added to the VLAN as a tagged 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).
GVRP must be activated globally as well as on each port. When it is activated, it transmits and
receives GARP Packet Data Units (GPDUs). VLANs that are defined but not active are not
propagated. To propagate the VLAN, it must be up on at least one port.
By default, GVRP is disabled globally and on ports.
GVRP Settings

STEP 1 Click VLAN Management > GVRP Settings.
STEP 2 Select GVRP Global Status to enable GVRP globally.
STEP 3 Click Apply to set the global GVRP status.
STEP 4 Select an interface type (Port or LAG), and click Go to display all interfaces of that type.
STEP 5 To define GVRP settings for a port, select it, and click Edit.
STEP 6 Enter the values for the following fields:
• Interface—Select the interface (Port or LAG) to be edited.
• GVRP State—Select to enable GVRP on this interface.
• Dynamic VLAN Creation—Select to enable Dynamic VLAN Creation on this
interface.
• GVRP Registration—Select to enable VLAN Registration using GVRP on this
