Release Information Statement introduced in Junos OS Release 12.1.
Description Specify the threshold for detecting the adaptation of the transmit interval. When the
BFD session transmit interval adapts to a value greater than the threshold, a single trap
and a single system message are sent.
Options milliseconds — Threshold value.
Range: 0 through 4,294,967,295 (2
32
– 1)
NOTE: The threshold value specified in the threshold statement must be
greater than the value specified in the minimum-interval statement for
the transmit-interval statement.
