As an implementation of GARP, GARP VLAN registration protocol (GVRP) maintains dynamic VLAN 

registration information and propagates the information to the other devices through GARP.  

With GVRP enabled on a device, the VLAN registration information received by the device from other 

devices is used to dynamically update the local VLAN registration information, including the information 

about the VLAN members, the ports through which the VLAN members can be reached, and so on. The 

device also propagates the local VLAN registration information to other devices so that all the devices in 

the same LAN can have the same VLAN information. VLAN registration information propagated by 

GVRP includes static VLAN registration information, which is manually configured locally on each 

device, and dynamic VLAN registration information, which is received from other devices.  

GVRP has the following three port registration modes: Normal, Fixed, and Forbidden, as described in 

the following. 

z 

Normal. A port in this mode can dynamically register/deregister VLANs and propagate 

dynamic/static VLAN information.  

z 

Fixed. A port in this mode cannot register/deregister VLANs dynamically. It only propagates static 

VLAN information. Besides, the port permits only static VLANs, that is, it propagates only static 

VLAN information to the other GARP members.  

z 

Forbidden. A port in this mode cannot register/deregister VLANs dynamically. It permits only the 

default VLAN (namely, VLAN 1), that is, the port propagates only the information about VLAN 1 to 

the other GARP members.  

GVRP is defined in IEEE 802.1Q standard.

The port on which GVRP will be enabled must be set to a trunk port.
