CMK version: 2.4.0p27.cme
OS version: RHEL 9
Was happy to see that this device was being added in werk 19562. We recently purchased one but nothing was discovered when added in 2.4.0p21. I just updated last night and expected to see services discovered.
Error message: No errors, just no services discovered.
Test Connection in the GUI shows empty values or “Got empty SNMP response”.
Upped the timeout to 4 seconds without much difference.
Updated the firmware for the device just in case.
Testing from the CLI using cmk --snmpwalk produces a file.

snmpbulkwalk responds with content but is missing the sysDescr

SNMPv2-MIB::sysContact.0 = STRING: Systems

SNMPv2-MIB::sysLocation.0 = STRING: Seattle
Based on the missing bulkwalk info, tried disabling bulkwalk for the device via rule.
No change.

Wondering if this is broken snmp and/or something with the plug-in.
I can provide more specifics if desired but appreciate any troubleshooting assistance.
Thanks for your time,
