I'm afraid that don't see what your complaint is about. What is it that you are looking for? What is the TEC guy expecting?
If you supply the baroc file, then all the TEC guy has to do is load it.

The default TEC setup is that every trap is a subset of EVENT (ISA EVENT). NetView comes along and introduces the ITS_BASE structure, so that
vendor traps become subclasses of TEC_ITS_BASE, and the NetView rule base defines TEC_ITS_BASE as a subclass of EVENT. That's how mib2trap defines each trap in the baroc file he creates. But mib2trap will take an optional parameter to specify an base class you want.

So if you want all your Cisco traps to have a base class of CISCO you can specify that. Then you'll have to provide an additional baroc definition which says that CISCO ISA EVENT, of course, or that CISCO ISA TEC_ITS_BASE. How you do it, is up to you. You can make your traps fit any hierarchy you want. It's not exactly rocket science. But it does require planning and effort, though once you have settled on your event schema, you should only have to do it once.

The mib2trap utility cannot be all things to all people; it just provides a starting point. And since TEC customization is totally up to the user, if you want something beyond what it gives you, then yes, you'll have to edit the addtrap and baroc files. But where is it written that you would never have to do that?
That's a lot easier than doing them all from scratch.

And incidentally, mib2trap in 7.1.5 offers even more customizing options than does 7.14 when you specify a baroc file. It will define all the MIB variables as slots in the event, and add STRING defs for them in the baroc, so that you can use them in TEC rules for correlation and duplicate detection. But you'll still have to examine the baroc and see whether it does what you want it to do. There's no free lunch.

[NV-L] TEC_CLASS consolidation


I am running NV 7.13 FP04 Sol9 soon to be 7.15 Sol10

I have a set of vendor supplied mibs that once compiled with mib2trap etc, yield 1400 individual TEC_CLASS defined in the .baroc file. The TEC admin does not want to see 1400 different CLASS defs.
Is there a way to handle situation such as this or am I stuck with a manual edit of the baroc to remedy this? This is becoming more and more frequent as we implement vendor/application specific mibs, so a repeatable process would be very useful if one exists.
