When the Network Configuration Manager device driver development creates a driver based on a customer request, the driver is developed against the requested device (given OID) and not the family that the device belongs to.
However, the driver can be modified in the field to expand the support for the driver to other products in the family. The base assumption to be able to do this is that the operating system, command line instructions and so on, of the devices are the same. But it may be a form factor that differs, such as 12, 24, 48-port versions of the product. Where it is a form factor difference, the driver can be easily updated in the field to support the new model of a certified/supported family of products.
