Hi Soumya,
This one is a bug in the trap sender. The timeticks value must be a
32bit value, but it has
33bits. Whireshark displays it, because it is a valid BER encoding, but
in SNMP it is not
allowed as the x43 syntax (Timeticks) is an on 32bit restricted INTEGER
syntax.
Best regards,
Frank

Hi Frank,
There is one more issue with SNMP4j (I think). There is another trap, which is
dropped by SNMP4j with the log entry: 2013-10-19 15:20:03,856 WARN
[DefaultUDPTransportMapping_0.0.0.0/162] snmp4j.MessageDispatcherImpl -
java.io.IOException: Only 32bit unsigned integers are supported at position 48.
But in other applications, including when it is captured and opened in
Wireshark, it works fine and all the data is available. I am attaching the hex
dump here. If needed, I can provide code snippets and Wireshark captures also.
Trap data: 30:82:01:84:02:01:00:04:06:70:75:62:6C:69:63:A4:82:01:75:06:0C:2B:06:
