Configuration restrictions and guidelines
• GVRP can work with STP, RSTP, or MSTP CIST but not PVST. When GVRP runs on the CIST,
blocked ports on the CIST cannot receive or send GVRP packets. For more information about
STP, RSTP, MSTP CIST, and PVST, see "Configuring spanning tree protocols."
• 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 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.
Configuration procedure
To configure GVRP functions on a trunk port:
Step Command Remarks
1. Enter system view.

N/A
2. Enable GVRP globally.
gvrp
Globally disabled by default.
3. Enter Ethernet interface
view, Layer 2 aggregate
interface view, or port
group view.
• Enter Ethernet interface view or
Layer 2 aggregate interface view:
interface interface-type
interface-number
• Enter port group view:
port-group manual
port-group-name
Use either command.
4. Configure the link type
of the ports as trunk.
port link-type trunk
Access by default.
For more information about the
port link-type trunk
command,
see Layer 2—LAN Switching
Command Reference.
5. Assign the trunk ports
to all VLANs.
port trunk permit vlan all
By default, a trunk port is
assigned to VLAN 1 only.
For more information about the
port trunk permit vlan all
command, see Layer 2—LAN
Switching Command Reference.
6. Enable GVRP on the
ports.
gvrp
Disabled by default.
7. Configure the GVRP
registration mode on
