well…
You have to configure the access controls. Everything is blocked by default in the new FW, even if snmp v1 is enabled.
so: v1 is working, v3 is failing, but also with snmpwalk - I’ll dig into it.
I did dig into it and what should I say… I’ll switch to the native SNMP integration and hack down OIDs manually. No additional tool with fishy configs.
Here’s my solution: Get data from APC Smart + Network Management Card via SMTP - #22 by man55
I used the iReasoning MIB browser and looked for the appropriate values from the APC PowerNet MIB.
(don’t forget to add a .0 at the end)
