You canchange the threshold by changingthe timeout time of the Join timer.JoinThis lower threshold is greaterthan or equal to twice the timeouttime of the Hold timer. You canchange the threshold by changingthe timeout time of the Hold timer.This upper threshold is less thanone-half of the timeout time of theLeave timer. You can change thethreshold by changing the timeouttime of the Leave timer.LeaveThis lower threshold is greaterthan twice the timeout time of theJoin timer. You can change thethreshold by changing the timeouttime of the Join timer.This upper threshold is less thanthe timeout time of the LeaveAlltimer. You can change thethreshold by changing the timeouttime of the LeaveAll timer.LeaveAllThis lower threshold is greaterthan the timeout time of the Leavetimer. You can change thresholdby changing the timeout time ofthe Leave timer.32,765 centisecondsNote:The following are recommended GVRP timer settings:z GARP hold timer: 100 centiseconds (1 second)z GARP Join timer: 600 centiseconds (6 seconds)z GARP Leave timer: 3000 centiseconds (30 seconds)z GARP LeaveAll timer: 120000 centiseconds (2 minutes)1.2.4 Configuring GVRP Port Registration ModeFollow these steps to configure GVRP port registration mode:To do ...
