There are devices in out of the box NCM device families that support NCM capabilites but do not have the Host Configuration tab enabled.
The device was originally in a custom device family and Spectrum moved it to the out of box device family which disabled the Host Configuration functionality when transferred.
This is resolved in 10.3.1 and above as well as in Spectrum_10.03.00.PTF_10.3.017 for 10.3.0:
This Patch provides the ability to move out of box devices to custom NCM families.
Below 2 new vnmrc options should be used to enable the feature
-- default value is false; This option allows to move the device from out of the box, on spectrum release it
will available in OC view.
-- default value is true; this option allows move the devices to out of the box when the device removed
from families search criteria.
Symptom: The moving device from out of box families is not allowed in Spectrum.
Resolution: Spectrum allows moving the devices from out of box Ncm families to the custom family.

An alternative workaround to fix the Host Configuration tab is to set the NCM_Device_Family_Index attribute to 1.
