Importing MIBs using Paessler MIB Importer and
Converter
In order to import MIB files from third parties (usually
the vendor of a device) into PRTG you must convert the files into OIDLIB files.
The MIB Importer and Converter Tool is available free of
charge on the Paessler website at www.paessler.com.
