HMAC-MD5-96 SNMPv3 TRAP

Hi,

Is it possible to decrypt HMAC-MD5-96 SNMP Traps (Port 162) in Wirehark? I just want to check the structure of the trap to make sure it is formatted correctly. I have tried adding in the authentication and privacy string into the SNMP Protocol Preferences in the format x..x.. etc but it does not decode the packet correctly.

Any advice/guideance would be appreciated.

Regards James.
