Command Usage
• 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
Note:
Set GVRP timers on all Layer 2 devices connected in the same network to
the same values. Otherwise, GVRP may not operate successfully.
