Group Address Registration Protocol is used by GVRP and GMRP to
•
register or deregister client attributes for client services within a
bridged LAN. The default values for the GARP timers are independent of
the media access method or data rate. These values should not be
changed unless you are experiencing difficulties with GMRP or GVRP
registration/deregistration.
Timer values are applied to GVRP for all the ports on all VLANs.
•
Timer values must meet the following restrictions:
•
leave > (2 x join)
•
leaveall > leave
