This object represents the high threshold on the retransmitted
RADIUS authentication messages per session. This is measured as
a percentage of crRadiusRetransmits. If the number of
retransmits is greater than or equal to this threshold, the
agent generates the crRadiusServerRetransHiNotif notification.
The value configured through this object should never be smaller
than that configured through crRadiusServerRetransThldNorm.
