● Join — A GARP device reliably transmits Join messages to other devices by sending each Join message two times. To
define the interval between the two sending operations of each Join message, use this parameter. The Dell Networking OS
default is 200 ms.
● Leave — When a GARP device expects to deregister a piece of attribute information, it sends out a Leave message and
starts this timer. If a Join message does not arrive before the timer expires, the information is deregistered. The Leave timer
must be greater than or equal to 3x the Join timer. The Dell Networking OS default is 600 ms.
● LeaveAll — After startup, a GARP device globally starts a LeaveAll timer. After expiration of this interval, it sends 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 10000 ms.
