The maximum number of entries allowed in the
pingProbeHistoryTable. An implementation of this
MIB will remove the oldest entry in the
pingProbeHistoryTable to allow the addition of an
new entry once the number of rows in the
pingProbeHistoryTable reaches this value.
Old entries are not removed when a new test is
started. Entries are added to the pingProbeHistoryTable
until pingCtlMaxRows is reached before entries begin to
be removed.
A value of 0 for this object disables creation of
pingProbeHistoryTable entries.
