Licensing Requirements and Limitations for GVRP
Involved Network Elements
Other network elements are not required.
Licensing Requirements
GVRP is a basic function of the switch, and as such is controlled by the license for basic software functions. The license for basic software functions has been loaded and activated before delivery. You do not need to manually activate it.

Software version evolution: V100R001C00 -> V100R002C00 -> V100R003C00 -> V100R003C10 -> V100R005C00 -> V100R005C10 -> V100R006C00 -> V200R001C00 -> V200R002C50 -> V200R003C00 -> V200R005C00 -> V200R005C10 -> V200R019C00 -> V200R019C10
Feature Limitations
When many dynamic VLANs need to be registered or the network radius is large, using default values of timers may cause VLAN flapping and high CPU usage. In this case, increase values of the timers. The following values are recommended depending on the number of VLANs.
Timer |
Number of Dynamic VLANs to Be Registered (N) |
|||
---|---|---|---|---|
N <= 500 |
500 < N <= 1000 |
1000 < N <= 1500 |
N > 1500 |

GVRP can be configured on the trunk interface only.
Switches on a network need to use the same settings of GVRP timers; otherwise, flapping may occur in the dynamic VLAN.
Global GVRP and VLAN-based Spanning Tree (VBST) cannot be configured simultaneously, and GVRP and Multichassis Link Aggregation Group (M-LAG) cannot be configured on an Eth-Trunk simultaneously.
The blocked port of STP, RSTP, MSTI 0, ERPS, or Smart Link can block GVRP messages.
The dynamic VLAN that is registered through GVRP cannot be configured as a reserved VLAN or the default VLAN configured by the port default vlan command. Information about a reserved VLAN cannot be transmitted to other devices through GVRP.
