I am currently looking to see who has SNMPv3 Traps setup and working in th 10.2 Beta and what your Configuration is on your Devices. I am gathering this information to finalize my SNMPv3 document that will be sent to customers on a basic Setup.
I am only looking for Cisco at the Moment, but feel free to put any Vendors configuration in this Thread for other customers who want to set this up on their devices as well.
