New Drafts

• Split PSAMP MIB into
• common IPFIX part
• PSAMP-specific part
• Created new IPFIX-EXPORTER-MIB module
• common IPFIX part of PSAMP MIB
• flow statistics (management information)
• flows reported, flows dropped, etc.
• Took IPFIX-COLLECTOR-MIB from concentrator MIB
  draft

IPFIX-EXPORTER-MIB

• Collector Table
• list of collectors to which messages are sent
• Collector address protocol used
• Report statistics
• Collector Group Table
• Groups collectors receiving the same reports
• Template Table
• Templates used by exporter
• Instance Table
• List of IPFIX meter instances
• Observation point(s)
• Packet selection
• Packet statistics
• Exporter ID
• Collector group
• Report statistics

IPFIX-COLLECTOR-MIB

• Exporter Table
• list of exporters from which messages have been
  received
• Exporter ID, address protocol used
• Exporter Statistics Table
• Bytes, packets, messages, flows, templates
• Discarded messages
• Observation Domain Statistics Table
• Messages, flows, templates
• Disordered sequence numbers
• Template Record Table
• Reporting templates in use
• Template Statistics Table
• flows

Open Issues

• Method Table Figure
• The figure must be adjusted to not show any
  particular OID since we don't define the methods
  right here. Also substitute OID by name!
• Need to achieve a common layout and naming on the
  different MIB parts.
• Need to decide how to structure the MIB (which
  one is the basic one, which one imports the root
  from the basic one).
• Elaborate security considerations, particularly
  concerning SET operations.

Document Status (Juergen)

• Early Version
• A lot of improvements required
• Only basic statistics in exporter MIB
• More statistics, flow statistics
• Consistency checking with IPFIX PSAMP
• Object naming, completeness of tables
• Harmonization between the two MIB modules
• Different statistics models
• Template reporting to be checked
• Many further details require fixing
• Basic direction is right
• Will probably need more time for completion than
  other drafts
