GVRP can be configured only on trunk ports.
GVRP is mutually exclusive with service loopback.
In an MSTP network, GVRP can run on only the CIST. In addition, blocked ports on the CIST
cannot receive/send GVRP packets.
If both GVRP and remote port mirroring are used, GVRP may register the remote probe VLAN to
unexpected ports, resulting in undesired duplicates to be received by the monitor port. For more
information about port mirroring, refer to Port Mirroring Configuration in the Access Volume.
Enabling GVRP on a Layer 2 aggregate interface enables both the aggregate interface and all
selected member ports in the corresponding link aggregation group to participate in dynamic VLAN
registration and deregistration.
On a GVRP-enabled trunk port, you need to configure the port trunk permit vlan all command on
the port to ensure that the traffic of all dynamically registered VLANs can pass through the port.
