GVRP Commands
GARP VLAN Registration Protocol (GVRP) is used to propagate VLAN
membership information throughout the network. GVRP is based on the
Generic Attribute Registration Protocol (GARP), which defines a method of
propagating a defined attribute (that is, VLAN membership) throughout the
network. GVRP allows both end stations and the networking device to issue
and revoke declarations relating to membership in VLANs. End stations that
participate in GVRP register VLAN membership using GARP Protocol Data
Unit (GPDU) messages. Networking devices that implement the GVRP
protocol and enable GVRP then process the GPDUs. The VLAN registration
is made in the context of the port that receives the GPDU. The networking
device propagates this VLAN membership on all of its other ports in the
active topology. Thus, the end station VLAN ID is propagated throughout the
network. GVRP is an application defined in the IEEE 802.1p standard that
allows for the control of 802.1Q VLANs.
