Where can I find the MIB modules?

A common question our support staff deal with is: Where can I find the MIB modules? What’s a MIB you ask?

Management Information Base (MIB) files define the information that can be provided by managed devices. The MIB files contain object identifiers (OIDs) and variables arranged in a hierarchy.

MIB That’s why we just published the new KB: 1013445 SNMP MIB Module File Download. The knowledge base article provides the steps to download the MIB files, and the Additional Information section points to some other related KB articles to help get you started with the MIBs.

As always, if you wish to provide any feedback on our KB articles, a feedback form is provided at the bottom.

Be sure to rate our KBs too using our 5 star rating system!
