I am trying to set up a Trap for a UPS on PRTG Network Monitor 18.104.22.1681. The device has SNMP v1 but works mostly on traps to send power off and power restore events.
I have created the trap on the main probe of PRTG itself.
Please see the settings configured (please note I have tried OID :22.214.171.124.4.1.2254.2.4.20 in accordance with the Wireshark results shown further below and OID: 126.96.36.199.4.1.324188.8.131.52, as suggested by this page Testing SNMP Trap (topic 10193), as I am using < 14.x)
Please see also the configuration set on the device itself:
The device has the ability to do a simulated event such as a power off. By doing this I am able to see within Wireshark the packets are received and from here also see what I believe should be the OID:
Using Netstat I can check for port 162. It seems to be correct, although not listening (please see also the task manager screenshot in the same image), however surely if the packets arrive to Wireshark then they are not being blocked at the Firewall and should arrive at the trap as expected..
Any more information I can give please let me know.
