434 | GARP VLAN Registration Protocol (GVRP)w w w . d e l l . c o m | s u p p o r t . d e l l . c o m • On the E-Series, C-Series, and non-S60/S55/S4810 S-Series, Per-VLAN Spanning Tree (PVST+) orMSTP and GVRP cannot be enabled at the same time, as shown in the example below. If SpanningTree and GVRP are both required, implement RSTP. The S60, S55, and S4810 systems do supportenabling GVRP and MSTP at the same time.FTOS(conf)#protocol spanning-tree pvstFTOS(conf-pvst)#no disable% Error: GVRP running.

Cannot enable GVRP.Configuring GVRPGlobally, enable GVRP on each switch to facilitate GVRP communications. Then, GVRP configuration isper interface on a switch-by-switch basis. Enable GVRP on each port that connects to a switch where youwant GVRP information exchanged. In the illustration below, that type of port is referred to as a VLANtrunk port, but it is not necessary to specifically identify to FTOS that the port is a trunk port.
