  1. Bidirectional Forwarding Detection Management Information Basedraft-ietf-bfd-mib-00.txt Thomas D. Nadeau Zafar Ali

  2. History of Changes • Submitted individual submission based on draft-katz-ward-bfd-01.txt. • Revised submission based on draft-katz-ward-bfd-02.txt • Published revised submission as a WG document

  3. BFD MIB Structure • General Variables • The General Variables are used to identify parameters that are global to the BFD process. • Session Table • The session table is used to identify a BFD session between a pair of nodes. • Session Performance Table • The session performance table is used for collecting BFD performance counts on a per session basis. • Session Mapping Table • Session Mapping Table maps the complex indexing of the BFD sessions to the flat “BFD Index” used in the BFD Session Table

  4. BFD Scalar Variables • BFD Admin Status object • BFD Operational Status object • BFD Version Number object

  5. BFD Session Table Entry • Describes BFD session configuration for entire box • Includes applications using BFD (I.e.: MPLS) • Provides a simple, flat indexing that can be reverse indexed using mapping table.

  6. Session Performance Table • Per Session • Packet In Count • Packet Out Count • Number of times session flapped • Session down time • Diag code for last session down event • Other Misc. session stats

  7. Session Mapping Table • Session Mapping Index, providing mapping between indexes and the BfdSessTable. • Supports indexing using • bfdSessApplicationId • bfdSessDiscriminator • bfdSessAddrType • bfdSessAddr.

  8. Notifications • Ability to enable/ disable Session Notifications • Notifications for “up” and “down” state transition

  9. Next Steps… • Revise MIB to make it consistent with draft-ietf-bfd-base-00.txt. • Evaluate impact of other WG documents and update MIB accordingly. • Will request for WG last call on next revised version (published after this meeting). • Need early MIB doctor review. • Working towards WG Goal • Submit BFD MIB to the IESG to be considered as Proposed Standard by November 2004.
