SNMP Driver Trap

[Kamil]

Hello,

I have problem with receiving traps from my switch.

I have Ethernet switch and I need to get information about power status. I set agent in SNMP Agent in System Management. I have MIB file and there is an OID address for traps from power. I load this in periphery address and set unsolicited receive mode but WinnCC doesn't see traps.
I was looking for traps also in internal datapoint ( _1_SNMPManager.Trap). Configuration of port (162), version (v1/v2) and Community (public/public) is OK, I think.

Wireshark sees forced traps between switch and computer, but they have 2 (1versionSNMP) or 3 (2v) items, maybe it is a problem?
First item includes OID address and second value what I need.

WinnCC sees normal information using pooling on the another OID, but I need traps.

Thank you for any answer.

Could you share the wireshark capture?
What does the log show with debug flag 26?

Hi,
I think I found a solution.
My computer has blocked receiving data by IP, because is in company network and only administrator can change this.
I get normal data from switch, because there is request first.
On virtual machine traps are working.
Thanks
