Description: The variable for each dsmonMatrixSD entry that the
dsmonMatrixTopNRate and dsmonMatrixTopNHCRate variables are
based upon.  Each dsmonMatrixTopN report generated on behalf
of this control entry will be ranked in descending order,
based on the associated dsmonMatrixSDTable counter,
identified by this object.

The following table identifies the dsmonMatrixSDTable
counters associated with each enumeration:

Enumeration                 RateBase MIB Objects

-----------                 --------------------
dsmonMatrixTopNPkts         dsmonMatrixSDPkts
dsmonMatrixTopNOctets       dsmonMatrixSDOctets
dsmonMatrixTopNHCPkts       dsmonMatrixSDHCPkts
dsmonMatrixTopNHCOctets     dsmonMatrixSDHCOctets

The following enumerations are only available if the agent
supports High Capacity monitoring:

dsmonMatrixTopNHCPkts
dsmonMatrixTopNHCOctets

This object MUST NOT be modified if the associated
dsmonMatrixTopNCtlStatus object is equal to active(1).
