Hi Narayanarao,

Which class (with line 101) do you mean?
Could you please also post the line content with some context?

Best regards,
Frank

Then please check it a third time. There are only two locations where this
error can happen. If a authentication protocol is missing or when a privacy 
protocol is missing - or if any passphrase is missing for it.

Thanks Frank for your reply.
i double checked and privacy pass phrase is set.
could you please let me know if enabling any debugs will help to narrow down the issue? 

-Narayanarao

P.S:- my trap forward code is failing only for 3des privacy protocol.

Hi,

Please fix the USM settings accoridng to the error message.
You are trying the use a security level that is not supported
by the protocol or by the provided security credentials.
For example if the secLevel is authPriv and you did not provide
a privacy passphrase, you will get this error.

Best regards,
Frank
