GARP VLAN Registration Protocol | 377

from VLAN 34 or VLAN 35 despite receiving a GVRP Leave message. Additionally, the interface will not 
be dynamically added to VLAN 45 or VLAN 46, even if a GVRP Join message is received.

GARP timers must be set to the same values on all devices that are exchanging information using GVRP:

•

Join: A GARP device reliably transmits Join messages to other devices by sending each Join message 
two times. Use this parameter to define the interval between the two sending operations of each Join 
message. The FTOS default is 200ms.

•

Leave: When a GARP device expects to de-register a piece of attribute information, it will send out a 
Leave message and start this timer. If a Join message does not arrive before the timer expires, the 
information is de-registered. The Leave timer must be greater than or equal to 3x the Join timer. The 
FTOS default is 600ms.

•

LeaveAll: Upon startup, a GARP device globally starts a LeaveAll timer. Upon expiration of this 
interval, it will send out a LeaveAll message so that other GARP devices can re-register all relevant 
attribute information. The device then restarts the LeaveAll timer to begin a new cycle. The LeaveAll 
timer must be greater than or equal to 5x of the Leave timer. The FTOS default is 10000ms.
