Hi VLefebure, all,
ignoring some potential magic inference handlers for now, the model type is the only place, where such information is stored.
This leaves you with 2 options to proceed: Model Type Editor or Policy Manager
While both may have their advantages and disadvantages, the Model Type Editor approach is difficult to use in case you have multiple GnSNMPDev for different types/different model naming reuqirements.

Raphael
