3Com Switch 8800 Configuration Guide Chapter 9 GARP/GVRP Configuration9-3Note that, the value of Join timer should be no less than the doubled value of Hold timer,and the value of Leave timer should be greater than the doubled value of Join timer andsmaller than the Leaveall timer value. Besides, you must set the value of the Join timerin terms of 5 centiseconds. Otherwise, the system will prompt message of error.The value range of a timer varies with the values of other timers. So if the value of atimer you want to set is not within the available value range, you can change the valuerange by changing the values of other related timers.z The lower limit of Hold timer is 10 centiseconds. You can change its upper limit bychanging the value of Join timer.z You can change the lower limit and upper limit of Join timer by changing the valueof Hold timer and Leave timer respectively.z You can change the lower limit and upper limit of Leave timer by changing thevalue of Join timer and LeaveAll timer respectively.z The upper limit of LeaveAll timer is 32765 centiseconds. You can change its lowerlimit by changing the value of Leave timer.9.1.3 Displaying and Debugging GARPAfter the above configuration, execute the display command in any view to display therunning of GARP configuration, and to verify the configuration.Execute the reset command in user view to reset the configuration of GARP.
