Hello everyone,
I'm having trouble monitoring a Schneider PLC with Zabbix using SNMPv3.
While SNMPv1/v2 work fine from Zabbix, and even SNMPv3 works with other MIB browsers, Zabbix gives me the specific error: cannot read from session: Bad parse of ASN.1 type.
This suggests the PLC is sending a slightly malformed response packet. To diagnose this, I need to compare it with a known-good packet.
Could anyone share a Wireshark capture of a successful SNMPv3 noAuthnoPriv response from a standard agent? I need it to compare the ASN.1 packet structures.
Thanks for your help!
