  1. Fibre Channel Routing MIBs Keith McCloghrie 2 August 2005

  2. FC Routing Information MIB • 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

  3. 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

  4. 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

  5. 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

  6. 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
