Hi bruce,

Please use our SNMP Tester (https://www.paessler.com/tools/snmptester), run it on the PRTG Host (or host of the Remote Probe), and perform a "Scan OIDlib", with the OIDlib File you have created, against the target device.
Which results do you get in the Tester? Please send us the result logfile from the Tester.

Best regards.
