Configuring a GARP Timer
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 Dell Networking OS 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
Dell Networking OS 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 Dell Networking OS default is
10000ms.
