  1. draft-perreault-opsawg-natmib-bis Presenter: Tina Tsou IETF 82, Taipei 2011-11-15

  2. NAT-MIB • RFC 4008 • Generic NAT MIB • IPv4 and IPv6 support (NAT[46][46]) • Required by draft-ietf-behave-lsn-requirements • Missing many features • Missing features are currently implemented in various proprietary MIBs • This suggests a need for standardization

  3. Missing Features(incomplete) • DS-Lite • Sharing address pools between interfaces • CGN • Per-subscriber state table indexing • Per-subscriber statistics • Per-pool statistics • Notifications for IP/port exhaustion, quota exceeded, etc. • Configurable limits and/or throttles for allocations • Low and a high thresholds in order to add more IP addresses or reclaim some if they are unused • NAT64 • Expose pref64 in MIB • Various semantics changes required • PCP • Do we need anything? • Various • Update to RFC 4787 terminology • Support protocols other than just TCP and UDP • Clarify existing traps • Add examples of DS-Lite, CGN, and NAT64 configurations

  4. Proposals • Add milestone to this working group’s charter: “Produce a revision of RFC 4008 taking into account recent developments such as DS-Lite, CGN, and NAT64.” • Adopt draft-perreault-opsawg-natmib-bisas WG document for fulfilling the above.

  5. BEHAVE? OPSAWG? V[46]OPS? • If this WG is not the right place for this work, where should it go instead?
