The maximum allowed jitter in the ingress trip time over the course
of any test. Jitter is defined as the difference between the
maximum and minimum ingress trip times measured over the course of
a single test (jnxPingResultsMaxDstSrct minus jnxPingResultsMinDstSrct).
If the measured jitter exceeds this threshold, a
jnxPingIngressJitterThresholdExceeded trap will be sent.
This applies only if the probe type (pingCtlType) provides one way
delay measurements. Currently jnxPingIcmpTimeStamp is the only
supported probe type with this property.
