Enter a value to specify the time between the transmission of GARP PDUs
registering (or re-registering) membership for a VLAN or multicast group in
centiseconds. Enter a number between 6 and 600. An instance of this timer
exists for each GARP participant for each port.
Enter a value to specify the time to wait after receiving an unregister
request for a VLAN or multicast group before deleting the associated entry,
in centiseconds. This allows time for another station to assert registration
for the same attribute in order to maintain uninterrupted service. Enter a
number between 12 and 3000. An instance of this timer exists for each
GARP participant for each port.
Enter a value to specify the Leave All Time controls how frequently Leave
All PDUs are generated. A LeaveAll PDU indicates that all registrations will
shortly be deregistered. Participants will need to rejoin in order to maintain
registration. The Leave All Period Timer is set to a random value in the
range of LeaveAllTime to 1.5*LeaveAllTime. The timer is specified in
centiseconds. Enter a number between 12 and 12000. An instance of this
timer exists for each GARP participant for each port.
