GVRP Settings
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).
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.
