Hi Larry Hayes,

Yes.  I have configured wireshark properly.
I have configured the wireshark to accept trap of credentials MD5+128 just
to verify settings are correct.

root#
root:~# snmptrap -v 3 -n "" -a MD5 -A mypassword -x *AES128* -X mypassword
-l authPriv -u putest128 -e 0x8000236e0300b0ae037994 10.12.73.118  ""
.1.3.6.1.4.1.8072.2.3.1 .1.3.6.1.4.1.8072.2.1.1 i 22222     <-----------
decrypt properly

root:~# snmptrap -v 3 -n "" -a MD5 -A mypassword -x *AES192* -X mypassword
-l authPriv -u putesting -e 0x8000236e0300b0ae037994 10.12.73.118  ""
.1.3.6.1.4.1.8072.2.3.1 .1.3.6.1.4.1.8072.2.1.1 i 123456  <---------
Throws 'Decrypted data not formatted as expected' error
root:~#

Attached wireshark snapshot for these two traps.
