Configuring GVRP 85■ The lower limit of Hold timer is 10 centiseconds. You can change its upper limitby changing the value of Join timer.■ You can change the lower limit and upper limit of Join timer by changing thevalue of Hold timer and Leave timer respectively.■ You can change the lower limit and upper limit of Leave timer by changing thevalue of Join timer and LeaveAll timer respectively.■ The upper limit of LeaveAll timer is 32765 centiseconds. You can change itslower limit by changing the value of Leave timer.Displaying andDebugging GARPAfter the above configuration, execute the display command in any view todisplay the running of GARP configuration, and to verify the configuration.Execute the reset command in user view to reset the configuration of GARP.Execute the debugging command in user view to debug the configuration ofGARP.Configuring GVRPGVRP Overview GARP VLAN Registration Protocol (GVRP) is a GARP application. Based on GARPoperating mechanism, GVRP provides maintenance of the dynamic VLANregistration information in the switch and propagates the information to otherswitches. All the GVRP-supporting switches can receive VLAN registrationinformation from other switches and dynamically update the local VLANregistration information including the active members and through which portthose members can be reached. All the GVRP-supporting switches can propagatetheir local VLAN registration information to other switches so that the VLANinformation can be consistent on all GVRP-supporting devices in one switchingnetwork. The VLAN registration information propagated by GVRP includes boththe local static registration information configured manually and the dynamicregistration information from other switches.GVRP is described in details in the IEEE 802.1Q standard. 3Com series switchesfully support the GARP compliant with the IEEE standards.Main GVRP configuration includes:■ “Enabling/Disabling Global GVRP”■ “Enabling/Disabling Port GVRP”■ “Setting the GVRP Registration Type”Table 62 Display and debug GARPOperation CommandDisplay GARP statistics information display garp statistics [ interface interface-list ]Display GARP timer display garp timer [ interface interface-list ]Clear GARP statistics information reset garp statistics [ interface interface-list ]Enable GARP event debugging debugging garp eventDisable GARP event debugging undo debugging garp event
