GVRP Commands 46917GVRP CommandsGARP VLAN Registration Protocol (GVRP) is used to propagate VLANmembership information throughout the network. GVRP is based on theGeneric Attribute Registration Protocol (GARP), which defines a method ofpropagating a defined attribute (that is, VLAN membership) throughout thenetwork. GVRP allows both end stations and the networking device to issueand revoke declarations relating to membership in VLANs. End stations thatparticipate in GVRP register VLAN membership using GARP Protocol DataUnit (GPDU) messages. Networking devices that implement the GVRPprotocol and enable GVRP then process the GPDUs. The VLAN registrationis made in the context of the port that receives the GPDU. The networkingdevice propagates this VLAN membership on all of its other ports in theactive topology. Thus, the end station VLAN ID is propagated throughout thenetwork. GVRP is an application defined in the IEEE 802.1p standard thatallows for the control of 802.1Q VLANs.Commands in this ChapterThis chapter explains the following commands:clear gvrp statisticsUse the clear gvrp statistics command in Privileged EXEC mode to clear allthe GVRP statistics information.clear gvrp statistics gvrp vlan-creation-forbidgarp timer show gvrp configurationgvrp enable (global) show gvrp error-statisticsgvrp enable (interface) show gvrp statisticsgvrp registration-forbid
