Presentation Transcript

  1. IPFIX MIB Modulesdraft-dietz-ipfix-mib-00 Thomas Dietz, Atsushi Kobayashi, Benoit Claise 66th IETF meeting, IPFIX session

  2. Past IPFIX-related MIB Activities • PSAMP MIB module • PSAMP work item • very close to completion • Concentrator MIB module • individual submission • first version just posted before IETF#65 2

  3. Scope of MIB Modules observation point/domain sampling & filtering parameters templates exporter statistics collector information Concentrator MIB collector statistics PSAMP MIB aggregation parameters exporter information 3

  4. Scope of MIB Modules IPFIX MIB modules observation point/domain sampling & filtering parameters (June 2006) templates exporter statistics collector information Concentrator MIB flow statistics collector statistics PSAMP MIB (June 2006) aggregation parameters Probe MIB exporter information Collector MIB 4

  5. 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 5

  6. 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 6

  7. 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 7

  8. 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. 8

  9. 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 9
