FAM-MIB content

• Six MIB-groups
• basic per-switch/per-Fabric information
• Database of assigned domains
• which PortIDs assigned in areas of local domain
• cache of recently released FC_IDs (for
  best-effort re-assignment to same port)
• commands (only one to initiate a Fabric Restart)
• three notifications assignment failed new
  principal switch fabric change (RCF/BF)

FAM-MIB Index-ing

• All tables INDEX-ed by
• fcmInstanceIndex fcmSwitchIndex
• via IMPORTS from FCMGMT-MIB
• FabricIndex
• for FC-SW-3, will always equal 1
• for (emerging) FC-SW-4, will identify a Fabric

Name Server MIB

• Internet-Draft is
• draft-desanti-fc-name-server-02.txt
• T11-FC-NAME-SERVER-MIB
• the Database of registered Nx_Ports and the
  information registered with/about them

  etc.)

NSM-MIB INDEX-ing

• INDEX-ing still under discussion
• Primary issue is that FC standards describe
  having one Name Server (per fabric)
• implementation is often distributed, e.g., on
  each switch
• does MIB need to represent registered info on a
  per-location basis?
• statisticsstate are different at different
  locations.
• Latest draft has
• fcmInstanceIndex fcmNsIndex likely to change
• and FabricIndex for registration info, stats
  rejects

NSM-MIB Status

• T11 Letter Ballot on second version
• Y38-N02-A12 (the same as FAM-MIB)
• Latest (fourth) version has been edited with some
  agreed resolutions
• Conference call last week
• closed a few more comments, but
• on INDEX-ing, resolution is at least as far away
  as it was before the call.
