Reset SNMPv3 Authentication deletes the cached engine ID, engine time, and engine boots for a device so that that information is re-discovered on the next poll. If reseting clears a management agent lost alarm but only for a short period of time, I would suspect that you either have a duplicate engine ID or that there is time drift either on the device or the spectrum host. I know that on 9.2 there are duplicate engine ID alarms, but I went right from 9.1.2 so I don't know if those are in 9.1.3 or not.
