The following table describes the items in the previous figure.
Item
Description
Join Time
Enter a value to specify the time between the transmission of GARP PDUs regis-
tering (or re-registering) membership for a VLAN or multicast group in centisec-
onds. Enter a number between 6 and 600. An instance of this timer exists for each
GARP participant for each port.
Leave Time
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.
Leave All Time
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 dereg-
istered. 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.
