SYNTAX Integer32 (-1..2147483647)
MAX-ACCESS read-create
STATUS current
DESCRIPTION
"The maximum number of entries that are desired in the
nlMatrix tables on behalf of this control entry. The probe
will not create more than this number of associated entries in
the table, but may choose to create fewer entries in this
table for any reason including the lack of resources.
If this object is set to a value less than the current number
of entries, enough entries are chosen in an
implementation-dependent manner and deleted so that the number
of entries in the table equals the value of this object.
If this value is set to -1, the probe may create any number
of entries in this table. If the associated
hlMatrixControlStatus object is equal to `active', this
object may not be modified.
This object may be used to control how resources are allocated
on the probe for the various RMON functions."

STATUS current
DESCRIPTION
"The total number of frames which were received by the probe
and therefore not accounted for in the *StatsDropEvents, but
for which the probe chose not to count for this entry for
whatever reason. Most often, this event occurs when the probe
is out of some resources and decides to shed load from this
collection.
This count does not include packets that were not counted
because they had MAC-layer errors.
Note that if the alMatrixTables are not implemented or are
inactive because no protocols are enabled in the protocol
directory, this value should be 0.
Note that, unlike the dropEvents counter, this number is the
exact number of frames dropped."

The probe will add to this table all pairs of addresses
