To restore the default settings of the timers, H3C recommends restoring the Join timer first, followed

by the Leave and LeaveAll timers.

Enabling GVRP compatibility

Perform this task to enable GVRP compatibility for MVRP when the peer device supports GVRP, so that the
local end can receive and send both MVRP and GVRP packets. For more information about GVRP, see

relevant protocols and standards.
GVRP compatibility enables MVRP to work with STP or RSTP, but not MSTP. When MVRP with GVRP

compatibility enabled works with MSTP, the network might operate incorrectly.
Disable the Period timer when you enable GVRP compatibility for MVRP. Otherwise, the VLAN status

might frequently change when the system is busy.
To enable GVRP compatibility:

Step Command

Remarks

1.

Enter system view.

N/A

2.

Enable GVRP

compatibility.
