Youcan change the thresholdby changing the timeouttime of the Join timer.JoinThis lower threshold isgreater than or equal totwice the timeout time ofthe Hold timer. You canchange the threshold bychanging the timeout timeof the Hold timer.This upper threshold isless than one-half of thetimeout time of the Leavetimer. You can change thethreshold by changing thetimeout time of the Leavetimer.LeaveThis lower threshold isgreater than twice thetimeout time of the Jointimer. You can change thethreshold by changing thetimeout time of the Jointimer.This upper threshold isless than the timeout timeof the LeaveAll timer. Youcan change the thresholdby changing the timeouttime of the LeaveAll timer.LeaveAllThis lower threshold isgreater than the timeouttime of the Leave timer.You can change thresholdby changing the timeouttime of the 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 ...
