In Ethernet interface view, the 
subsequent configurations apply 
to the current port. 
z 
In port group view, the 
subsequent configurations apply 
to all ports in the port group. 
z 
In Layer-2 aggregate interface 
view, the subsequent 
configurations apply to the 
Layer-2 aggregate interface and 
all its member ports. 
Enable GVRP on the port  
gvrp 
Required 
Disabled by default 
Configure the GVRP 
registration mode on the 
port  
gvrp registration { fixed | 
forbidden | normal } 
Optional 
The default is normal. 
 
  
z 
GVRP is mutually exclusive with service loopback.  
z 
In an MSTP network, GVRP can run on only the CIST. In addition, blocked ports on the CIST 
cannot receive/send GVRP packets.  
z 
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. 
z 
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. In addition, the GVRP configuration made on a link aggregation 
member port can take effect only after the port is removed from the group. For more information 
about link aggregation, refer to Link Aggregation Configuration in the Access Volume. 
z 
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.  
 
Configuring GARP Timers 
Among the four GARP timers, the LeaveAll timer is configured in system view and takes effect on all 
ports, while the other three are configured on a port basis. 
Follow these steps to configure GARP timers:
