Answer:

When Spectrum models one of these specific devices, if the Model Class is set to auto, Spectrum determines what the Model Class should be set to based on mib support on the device.

 

The following is from the "How CA Spectrum Identifies the Model Class" section of the documentation.

How CA Spectrum Identifies the Model Class

CA Spectrum evaluates the model class when a device is modeled for the first time and when you reconfigure a device model.

The following process describes how CA Spectrum determines the model class to assign to a device model:

1. If the model class setting is locked, CA Spectrum does not reevaluate the device model. The model class that is set for the device model remains as is.

2. If the model class setting is not locked, CA Spectrum checks device model support for a specific MIB object. If CA Spectrum detects that a device model supports a certain MIB object, the model class for that device model is set to a specified value.

3. If the search for a supported MIB object fails, CA Spectrum attempts to determine the model class for the device model. CA Spectrum uses the mappings in the Device Certification utility in this search. This utility provides a mapping from System Object ID (which is more general than a MIB object) to Model class.

4. If Device Certification does not contain any model class mappings for a device, CA Spectrum defaults to setting the model class based on whether the device appears to be routing (“Router”), switching (“Switch”), both switching and routing ("Switch-Router”) or simply repeating (“Repeater”).

When assigning the icon and label for a device model, CA Spectrum uses the icon for the model class that is assigned as described here. This icon appears throughout OneClick.
