The maximum allowed jitter in the egress trip time over the course
of any test. Jitter is defined as the difference between the
maximum and minimum egress trip times measured over the course of
a single test (jnxPingResultsMaxSrcDstt minus jnxPingResultsMinSrcDstt).
If the measured jitter exceeds this threshold, a
jnxPingEgressJitterThresholdExceeded 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.
