Hi Frank

Here is the hex dump of the trap.

Trap data: 30:81:E1:02:01:00:04:06:70:75:62:6C:69:63:A4:81:D3:06:04:91:6D:7A:27:

:77:61:69:74:69:6E:67:5F:66:6F:72:5F:6F:62:6A:65:63:74

If you want, I can also provide the Wireshark capture file for the trap.

Hi Soumya,

You can send the hexdump of the trap PDU to support at snmp4j.org.
There is no known issue. Some devices/agents implement a wrong length encoding of BER elements, but its not clear what could have caused that issue from the facts your provided.

Best regards,
Frank
