What You Need To Know About MIB Objects

So I'm reading the MIB. What information am I looking for?

You do not need to carefully read over every last line of the MIB file. For your purposes, you are only looking for particular items that will tell you what elements of the device you can monitor and control.

A well-written MIB will be divided into sections. Sections will be identified by comment lines. (In MIB notation, comment lines are identified by two hyphens.) So if you find a line that reads something like:

-- IMPORT definitions

The import definitions are typically at the very top of the file. The import definitions tell you what other MIB files, the current Mib file you are working with, relies upon. When compiling your MIBs, you need to ensure that you have all of your dependencies for all of your MIBs or they will be missing data that is crucial to accurately representing information

-- TRAP definitions

You know you have found what you are looking for.

There are also text labels that identify the MIB objects you are interested in. For example, in SNMP v1 MIBs, Traps are identified by the text label "TRAP-TYPE." If you know the text labels for the kinds of objects you are looking for, you can scan the MIB in a series of Ctrl-F searches.

The MIB objects you need to know

From the perspective of a telemetry manager, what you need to know from the MIB is:

  1. What other RFC MIBs you need to support this device
  2. What event reports (Traps) the device can send to the SNMP manager
  3. What information you can request from the device (the SNMP equivalent of an alarm poll)
  4. What characteristics of the device you can control via SNMP
