Implementation Report for RFC 2613
Remote Network Monitoring MIB Extensions for Switched Networks

WG Chair: Andy Bierman

------------------------------

Introduction
------------

This report summarizes the implementation reports received
for RFC 2613. A survey for this RFC was sent to the WG
mailing list and the results shown below are aligned with
that survey form.

Survey Issues
-------------

All MIB objects in RFC 2613 have been implemented by at least
two independent development efforts. Two minor issues did
arise:

    1) smonDataSource values
          Not all possible values of the smonDataSource object
          have been implemented by at least two developers.
          This is not considered a significant issue because each
          mode is specific to a different hardware platform
          environment, and different vendors used the values
          appropriate for their hardware platform(s).

    2) portCopy modes
          The portCopyTable can be populated in three different
          ways (using the same MIB objects). The difference in
          each mode is related to associated rows in the portCopyTable.
          For example, the 'N:1' mode implies there are at least two
          rows in the table with the same port copy destination.
          Not all possible modes have been implemented by at least
          two developers. This is not considered a significant issue
          because all MIB objects in this table have been implemented
          in a consistent and interoperable manner by at least two
          developers. The 'N:1' and 'N:M' modes are dependent
          on the capabilities of the hardware platform.

Survey Conclusion
-----------------

The RMONMIB WG believes the requirements for advancement of
the MIB in RFC 2613 to Draft Standard have been met.

Survey Respondents
------------------

There were four responses, labeled 'A' through 'D' in the
response summary section, which correspond to the following
vendor implementations:

      A == Avaya agent
      B == Netscout agent and NMS
      C == Cisco Catalyst Supervisor agent
      D == Cisco Network Analysis Module agent

Note that 'C' and 'D' do not represent completely independent
implementations and are grouped together for standards
advancement consideration purposes. They are shown separately to
demonstrate the typical differences between a probe
implementation and an embedded switch implementation.
