INTERFACETOPN-MIB Table View

A table of control records for reports on the top `N'
interfaces for the value or rate of a selected object.
The number of entries depends on the configuration of the agent.
The maximum number of entries is implementation
dependent.

interfaceTopNControlEntry row .1.3.6.1.2.1.16.27.1.2.1

A set of parameters that control the creation of a
report of the top N ports according to several metrics.

A table of reports for the top `N' ports based on
          
setting of associated control table entries. The
maximum number of entries depends on the number
of entries in table interfaceTopNControlTable and
the value of object interfaceTopNGrantedSize for
each entry.
          
For each entry in the interfaceTopNControlTable,
interfaces with the highest value of
interfaceTopNValue shall be placed in this table
in decreasing order of that rate until there is
no more room or until there are no more ports.

interfaceTopNEntry row .1.3.6.1.2.1.16.27.1.3.1

A set of statistics for an interface that is
part of a top N report.
