Parse SNMP MIB Files to generate a list of Devices and OID

python parsing snmp oid mib

I am processing a large number of SNMP MIB Files and from them creating a dictionary of devices and their respective ID, in the form "1.3.6.1.4.1.9.1.694":"catalyst296024".

I am currently using Mibble for the MIB parsing part as after trying out other apps/modules, I found it to be the ideal. Then I am using python to work on the data.

My problem is that I only need the "device name & OID". Since when I parse I am getting all the OID data I have not yet managed to find a way to intelligently identify the device and ignore the rest of the stuff. (Short of physically looking at the data line by line)

One of the easiest things to do would be to use Net-SNMP's mib2c program, which will let you write a quick output based on a set of MIB objects. See it's wiki page for details on how to write mib2c scripts.

Also, you could simply parse the output of a command, like snmptranslate that will print a tree structure output (use -Tp) that is likely easier to parse than the MIB file itself.
