       DESCRIPTION

-- The Interface Top N group is used to prepare reports that
-- describe a list of interfaces (data sources)
-- ordered by the values of one
-- of the objects that apply to the interfaces of the respective device.
-- Those objects are defined by standard MIBs. The exact objects that
-- are supported by the agent are described by interfaceTopNCaps
-- The objects must be elements in tables indexed only by an
-- InterfaceIndex object.
-- The objects  chosen by the


-- management station may be sampled over a management
-- station-specified time interval, making the report rate based.
-- The management station also specifies the number of interfaces
-- that are reported.
--
-- The interfaceTopNControlTable is used to initiate the generation
-- of a report.  The management station may select the parameters
-- of such a report, such as which object, how
-- many interfaces, and the start & stop times of the sampling.  When
-- the report is prepared, entries are created in the
-- interfaceTopNTable associated with the relevant
-- interfaceTopNControlEntry.  These entries are static for
-- each report after it has been prepared.

    Because SNMP access control is articulated entirely in terms

    only those objects that exist in a particular MIB view.
    Because there is thus no acceptable means of restricting the

    mechanism, the probe must only grant write access to this
    object in those views that have read access to all objects on
    the probe.

 Example:
  The following set of values is applied to a device with multiple

  interfaceTopNObjectVariable = 'ifInOctets'
  interfaceTopNObjectSampleType = 'deltaValue'

  Applying this set of values will result in the sampled delta values
  to be multiplied by 100 for the 10 Mbps interfaces, and by 10 for
  the 100 Mbps interfaces, while the sample values for the 1 Gbps
  interface are left unchanged. The effective speed of the interface is
  taken from the value of ifSpeed for each interface, if ifSpeed is
  less than 4,294,967,295, or from ifHighSpeed multiplied by
