I have few devices (cisco, APC, HP etc), and i have some SNMP (v3) sensors for it.
After i have change SNMP password for cisco devices, its SNMP sensors stopped to work. What I've done:
- Re-create devices
- Update PRTG to latest stable version
- Restart probe and server services. All this actions had no success for me. Credential I entered is absolutely correct, I check it via Paessler SNMP tester (check uptime of devices).
How can I fix this problem?
