DX NetOps Performance Management provides a method where the discovered devices can be set to use different Device Type assignments than the product uses by default.
We Override the Device Types and Context Types by editing the DeviceTypes.xml file on the Data Aggregator.
If this isn't working as expected we can enable debug to track the messaging for the function in search of a cause.
All supported DX NetOps Performance Management releases
