12.7.47 SNMP V3 decoding with wireshark

Frequently wireshark traces may have a message "encrypted PDU: privkey known".
Be not worried about this message. This message generally appears when Wireshark simply does not know
about the used private credentials and as the package is encrypted it says "privKey Unknown". This message
does not make impact on 8770 alarm application.
In order to have a proper display in wireshark, the used credentials should be configured in wireshark in the
following path.
"Edit -> preferences -> protocols -> SNMP -> users table". Click on edit button and add a new table.
