  • For protocol-independent routing information
  • One MIB table of FC Routes
  • by which FC frames can be forwarded
  • Contains both:
  • static routes, and
  • routes learned via a routing protocol
  • I.e., not all these routes are necessarily being used at present
  • FC Routing Information MIB (cont)
  • Each route is per-switch and per-Fabric
  • Each route can be INDEX-ed by:
  • source address & mask
  • destination address & mask
  • how learned (e.g., FSPF, netMgmt, etc.)
  • interface on which FC frame was received
  • Each route specifies:
  • interface on which to forward the frame
  • the next hop
  • the metric
  • FSPF MIB
  • For information specific to FSPF
  • Each MIB table is per-switch & per-Fabric
  • One table for switch parameters, variables, state and stats:
  • FSPF Region number
  • FSPF Timers & intervals
  • Path computations, discards, chksum errors
  • Admin/Oper Status, notifications enable/disable
  • # of LSRs in current Link State DB
  • FSPF MIB (cont)
  • One table of per-interface info:
  • FSPF timer intervals
  • Stats:
  • in/out LSUs/LSAs/Hellos, retransmits/errors
  • Neighbor’s address & port-index
  • Admin state & FSPF (neighbor) state
  • Link cost factor
  • FSPF MIB (cont)
  • Two MIB tables for the Link State Database
  • one table of LSRs
  • header info from LSR
  • LSR’s age (how long in DB)
  • one table of link-info in LSRs
  • info from LSR
  • One notification:
  • On change of FSPF Neighbor’s State
