Configuring GVRP functions
Before enabling GVRP on a port, you must enable GVRP globally. In addition, GVRP can be configured
only on trunk ports, and you must assign the involved trunk ports to all dynamic VLANs.
Follow these steps to configure GVRP functions on a trunk port:
To do… Use the command… Remarks
Enter system view system-view ––
Enable GVRP globally gvrp
Required
Globally disabled by
default.
Enter Ethernet

Required
Use either command.
Enter port-group view
port-group manual
port-group-name
Configure the link type of the ports as trunk port link-type trunk
Required
Access by default.
Assign the trunk ports to all VLANs port trunk permit vlan all
Required
By default, a trunk port is
assigned to VLAN 1
only.
Enable GVRP on the ports gvrp
Required
Disabled by default.
Configure the GVRP registration mode on the
port gvrp registration { fixed |
forbidden | normal } Optional
normal by default.
NOTE:
•
For more information about the port link-type trunk and port trunk permit vlan all commands, see the
Layer 2 Command Reference.
• GVRP is mutually exclusive with service loopback.
• GVRP can work with MSTP CIST. When GVRP runs on the CIST, blocked ports on the CIST cannot
receive/send GVRP packets.
• Do not enable both GVRP and remote port mirroring. Otherwise, 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, see the
Network Management and Monitoring Configuration
Guide.
• 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.
