Potential issue with SNMP. Have been monitoring our WS-10-250-AC running 1.3.9 with PRTG. I have 5 SNMP Traffic monitors set up - on 5 different ports. Working great for 2 weeks. Today, without provocation, the SNMP traffic monitoring off all 5 ports stopped at the same time. PRTG reported those as unreachable. I was getting SNMP traffic from a bunch of devices on the other side of the switch. Pings to the switch were fine. No other issues with the switch other than SNMP stopped.
No log entries at all for today on the Netonix (not unusual but nothing about SNMP stopping). The only way to get them back was to turn off SNMP on the switch and then turn it back on again. Everything has been fine since.
Error in PRTG: "No response (check: firewalls, routing, snmp settings of device, IPs, SNMP version, community, passwords etc) (SNMP error # -2003)"
