pysnmp如何加载asn.1格式的自定义MIB模块

Question

I am having trouble in figuring out how to load custom MIBs which with .txt extensions using pysnmp module

This is what I am doing currently

b = builder.MibBuilder()
compiler.addMibCompiler(b, sources=[mib_location])

mib_location is folder on which all my MIBs are located. something like file:///<my_folder>

But still I am not able to load these MIBs.

I am thinking that may be I'll have to specify that my MIBs have an extension of .txt but not sure where.

Answer 1

MIB files should be found by MIB module name without any extension or with .txt one.

Here is an example that should work out of the box.

If not, try adding:

from pysmi import debug
debug.setLogger(debug.Debug('all'))

To your script and watch stdout -- pysmi will report where exactly it is looking for MIB files. Hope it gives you enough information to figure out what goes wrong.
