An instance of this timer exists for each GARP participant for each port.

unregister request for a VLAN or multicast group before deleting the associated entry.
This allows time for another station to assert registration for the same attribute to maintain

Timer field, specify how frequently (in centiseconds) LeaveAll PDUs are
generated.
A LeaveAll PDU indicates that all registrations will be deregistered soon. To maintain
registration, participants must rejoin.

the range of LeaveAllTime to 1.5 * LeaveAllTime. The timer is specified in centiseconds.
Enter a number between 200 and 6000 (2 to 60 seconds). The default is 1000
