LeaveAll Timer This Leave All Time controls how frequently LeaveAll PDUs are generated. A
LeaveAll PDU indicates that all registrations will shortly be deregistered. Par-
ticipants will need to rejoin in order to maintain registration. There is an
instance of this timer on a per-Port, per-GARP participant basis. The Leave All
Period Timer is set to a random value in the range of LeaveAllTime to
1.5*LeaveAllTime. Permissible values are 200 to 6000 centiseconds (2 to 60
seconds). The factory default is 1000 centiseconds (10 seconds). The finest
granularity of specification is 1 centisecond (0.01 seconds).
Port GMRP Mode Indicates the GMRP administrative mode for the port. It may be enabled or dis-
abled. If this parameter is disabled, Join Time, Leave Time and Leave All Time
have no effect. The factory default is disabled.
