We recently upgraded all of our Cisco Switch. We have restarted them and since then we have 30 sensors that no longer work in PRTG, With the following error message: No such instance (SNMP error #223)
I've seen in your knowledge base that for ports, this comes from the fact that the port number has changed. But how to find the right number? And how to change it in the sensor settings?
I have the same problem for other sensors: System Health Alimentation System Health Tensions System Health Courants System Health Autre
I do not know PRTG well, can you help me?
