Operation Manual – GVRPH3C S9500 Series Routing Switches Chapter 1 GVRP Configuration1-2GARP and GMRP are described in details in the IEEE 802.1P standard (which hasbeen merged to the IEEE802.1D standard). H3C series switches fully support theGARP compliant with the IEEE standards.The following section describes the GARP configuration task:z Setting GARP TimersNote:z The configuration of the GARP timers will be used for all the GARP applications,including GVRP and GMRP, running in one switched network.z In one switched network, the GARP timers on all the switching devices should beset to the same value. Otherwise, GARP applications cannot work normally.1.1.2 Introduction to GVRPThe GARP VLAN Registration Protocol (GVRP) is a GARP application. Based on theGARP operating mechanism, GVRP provides maintenance of the dynamic VLANregistration information in the switch and propagates the information to other switches.All the GVRP-enabled switches can receive VLAN registration information from otherswitches and dynamically update the local VLAN registration information including theactive members and through which port those members can be reached. All theGVRP-enabled switches can propagate their local VLAN registration information toother switches so that the VLAN information is consistent on all GVRP-enabled devicesin one switching network. The VLAN registration information propagated by GVRPincludes both the local static registration information configured manually and thedynamic registration information from other switches.GVRP is described in details in the IEEE 802.1Q standard. H3C series switches fullysupport the GARP compliant with the IEEE standards.Configuring GVRP primarily involves the following tasks:z Enabling/Disabling Global GVRPz Enabling/Disabling Port GVRPz Setting the GVRP Registration TypeIn the above-mentioned configuration tasks, GVRP should be enabled globally before itis enabled on a port. Configuration of GVRP registration type can only take effect afterport GVRP is enabled. Besides, GVRP should be configured on trunk ports.
