Important Considerations

■You can use this command to configure the same setting on multiple ports simultaneously. When you specify multiple port numbers, the system prompts you to choose the setting and then applies it to all of the ports.

■To activate GVRP in your system, you must enable it for the entire bridge (see “bridge gvrpState”in Chapter 9) as well as on individual bridge ports (this command). If you enable GVRP on a port but you have not enabled it for the bridge, GVRP does not function.

■To maximize the effectiveness of GVRP, it should be enabled in as many end stations and network devices as possible.

■GVRP updates are not sent to any blocked Spanning Tree Protocol (STP) ports. GVRP operates only on ports that are in the forwarding state.

■If GVRP is enabled on the bridge and on a given port which changes to the STP forwarding state, the port automatically begins to participate in GVRP.

■VLANs that are created dynamically with GVRP exist only as long as a GVRP-enabled device is sending updates — if the devices no longer send updates, GVRP is disabled, or the system is rebooted, all dynamic VLANs are removed, but the system leaves unchanged all VLANs that were statically configured through a management interface.
