How the DX NetOps Portal integration with a DX NetOps Spectrum Data Source functions for device synchronization and discovery functionality.
This Knowledge Base Article shall discuss the functionality around the DX NetOps Portal and DX NetOps Spectrum integration device synchronization and discovery functionality.

It is important to start with the fact that Spectrum does not integrate with DA directly.
We often think of it this way, because we talk about using Spectrum to seed the DA with devices and their elements, but there are some subtleties to what's going on under the hood.
There may be a misconception among some users that the contents of the special Portal IP Domain based Global Collection models in Spectrum will result in an IP list match between the "<DomainName>" Discovery Profile in Portal. There is not always a one to one relationship between the IP addresses of device models that are members of those special Global Collections (GC) and the "<DomainName>" Discovery Profile in Portal's DA views.
When a Spectrum OneClick server is added as a Data Source (DS) in Portal, Portal pushes IP Domains to Spectrum OneClick. The "integration" code in Spectrum OneClick implements this push by the creation of Portal IP Domain based models in Spectrum. Although the Portal IP Domain model type is derived from a Global Collection it is important to understand that it is not a Global Collection as might be normally known to Spectrum users. There are special behaviors that go along with this model type that are not available to normally created Global Collections in Spectrum.
At this point in Spectrum you should see a Portal IP Domain based model for each IP Domain in Portal. They will be found in the Spectrum OneClick client console under the Global Collection listings at the global level of that view, independent of other landscapes configured in Spectrum. The user can then configure search criteria or manually add devices to these Portal IP Domain based Global Collections, the same as can be done for other standard Global Collections.
Once devices are added to those Global Collections as members, on the subsequent synchronization cycle pull phase from the Spectrum Data Source in Portal, those devices are synchronized to Portal. This is important for a couple of reasons:
That is the "nuts and bolts" of how Spectrum participates in Inventory synchronization with Portal.
Independent of the above information, the DA is a special Data Source unlike the others created for integration with Portal, such as the Spectrum Data Source.. It can be configured to discover devices from other Data Sources. Notice the terminology "other Data Sources". It is important to understand that function is not specifically limited to the Spectrum Data Source. When this switch is enabled for the DA., when the DAs next synchronization cycle arrives, any devices in Portal which the DA does not know about are pushed to the DA.
What the DA does with them is add the IP to a system configured Discovery Profile which is maintained for each IP Domain. A key point:
