GVRP enables a device to propagate local VLAN registration information to other participant devices 

and dynamically update the VLAN registration information from other devices to its local database 

about active VLAN members and through which port they can be reached. It thus ensures that all GVRP 

participants on a bridged LAN maintain the same VLAN registration information. The VLAN registration 

information propagated by GVRP includes both manually configured local static entries and dynamic 

entries from other devices.  

GVRP provides the following three registration types on a port:  

z 

Normal –– Enables the port to dynamically register and deregister VLANs, and to propagate both 

dynamic and static VLAN information.  

z 

Fixed –– Disables the port to dynamically register and deregister VLANs or propagate information 

about dynamic VLANs, but allows the port to propagate information about static VLANs. A trunk 

port with fixed registration type thus allows only manually configured VLANs to pass through even 

though it is configured to carry all VLANs.  

z 

Forbidden –– Disables the port to dynamically register and deregister VLANs and to propagate 

VLAN information except information about VLAN 1. A trunk port with forbidden registration type 

thus allows only VLAN 1 to pass through even though it is configured to carry all VLANs.  

GVRP is described in IEEE 802.1Q. 

 

GVRP can only be configured on trunk ports.

Before enabling GVRP on a port, you must enable GVRP globally. 

Follow these steps to configure GVRP functions on a trunk port:
