parameters beginning with the transmission interval. The range is from 50 to 1000. The
default is 200.
min_rx milliseconds Enter the keywords min_rx to specify the minimum rate at which the local system
receives control packets from the remote system. The range is from 50 to 1000. The
default is 200.
multiplier value Enter the keywords multiplier to specify the number of packets that must be missed
in order to declare a session down. The range is from 3 to 50. The default is 3.
