I am trying to load one of our WS-12-250-DC into prtg and I have it connected via a pepwave radio with udp port 161 forwarded to the switch. I keep getting the old -2003 error in prtg and it fails to import any sensors from the switch. (No response (check: firewalls, routing, snmp settings of device, IPs, SNMP version, community, passwords etc) (SNMP error # -2003)

I have tried doing a port scan via https://www.ipfingerprints.com/portscan.php and it does show that port 161 is open and accepting connections.

any advice? I dont see anywhere in the switch config to change wich port snmp traffic uses... is that configurable?

At present the snmp port is not configurable. That's something I can look into if necessary. In the mean time have made any changes to your Access Control settings?

No, I have left the access control tab all default settings. its set to enable with 5 attempts and 60 seconds between and nothing configured below

What version of firmware are you running at present?

1.5.2 Board Rev F

SNMP was definitely working in that version. Is your switch publically accessible? If it isn't, I don't see how that port scanning tool would be of much help if it can't get through your NAT. Maybe it might be better to try and run a port scan with NMAP on the host machine that has PRTG on it?

I did get it working, I believe the error was in my prtg configuration. all snmp data is working as expected. thank you

Glad it worked out.
