GVRP configuration task list
Task Remarks
Configuring GVRP functions Required.
Configuring GARP timers Optional.
GVRP configuration made in Ethernet interface view or Layer-2 aggregate interface view takes effect on
the current interface only. GVRP configuration made in port group view takes effect on all the member
ports in the group.
GVRP configuration made on a member port in an aggregation group takes effect only after the port is
removed from the aggregation group.
Configuring GVRP functions
Configuration restrictions and guidelines
• 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.
• GVRP is mutually exclusive with service loopback.
• 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/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 might 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

Step Command Remarks
1. Enter system view. system-view N/A
