Look at the thread for the 'tell us your unknown devices' there are over 800 posts there with customers telling SW their unknown devices.
It's time (and more) for there to be a way to administratively specify the sysObjectID -> Vendor and MachineType mappings
Once this is done then we will have somewhere to also add other configuration items such as:
- UnDP pollers added to discovered devices based on the sysObjectID so we do not have to add them manually
- customer provided UnDP pollers for memory and CPU so these get graphed for 'unknown' devices
