Actually, it looks like you can just supply those files as additional command line arguments. Try the attached, I fixed some of the errors. I can't figure out why it's complaining about ifIndex, but I do see the same message for some other MIBs I tried -- including a copy of the standard RFC 1156 MIB... However, the output looks fine if you use -k with that. paul On Jan 10, 2013, at 4:59 PM, Brian Hechinger wrote: Anyone ever mess with this? wonko at fred$ smidump -f python OLD-CISCO-DECNET-MIB.my OLD-CISCO-DECNET-MIB.my:15: failed to locate MIB module `RFC-1212' OLD-CISCO-DECNET-MIB.my:17: failed to locate MIB module `RFC1213-MIB' OLD-CISCO-DECNET-MIB.my:19: failed to locate MIB module `CISCO-SMI' OLD-CISCO-DECNET-MIB.my:21: unknown object identifier label `temporary' OLD-CISCO-DECNET-MIB.my:283: index element `dnArea' of row `dnAreaTableEntry' must have a range restriction OLD-CISCO-DECNET-MIB.my:443: index element `dnHIdx1' of row `dnHostTableEntry' must have a range restriction OLD-CISCO-DECNET-MIB.my:451: index element `dnHIdx2' of row `dnHostTableEntry' must have a range restriction OLD-CISCO-DECNET-MIB.my:476: unknown object identifier label `ifIndex' smidump: module `OLD-CISCO-DECNET-MIB.my' contains errors, expect flawed output smidump: aborting due to severe parsing errors smidump: use the -k option to force continuation wonko at fred$ I need to do that so I can convert it into whatever nonsense PySNMP needs. -brian
