Overview of GVRP

To manually create or delete VLANs for all the devices in a large and complex network, the workload will be very heavy, and it is very easy to make a configuration mistakenly for network administrator. In this case, users can complete the VLAN configuration through GVRP dynamic VLAN creation function.

GARP VLAN Registration Protocol (GVRP) is an application of Generic Attribute Registration Protocol (GARP) that is used to propagate and register VLAN configuration information on interfaces among devices. After the device enables GVRP, it sends the local VLAN configuration information to other devices, and also receives VLAN configuration information from other devices, so as to dynamically updates local VLAN configuration information to keep consistent with other devices in the network, which greatly reduces the VLAN configuration work for network administrator.

When the network topology changes, GVRP re-propagates and registers VLAN configuration information according to the new topology, so as to make VLAN configuration information on all the GVRP devices be updated synchronously with the network topology.

GVRP Timer

The supported GVRP timers are shown in the following table. Currently, changing the value of the timer is not supported.

GVRP edge-switch

For the GVRP access switch connected the host, when this switch forms a loop with other devices, it causes the GVRP messages received by this device to be forwarded cyclically over the same set of links, which consumes bandwidth and causes overutilization. To solve this problem, users can configure the following command to enable GVRP edge-switch function on the host-side switch, then the edge switch will not forward the received GVRP messages.
