DNAC - Get Switch Hierarchy via API

[evanm]

Hello Community,

I am not sure if I am overlooking something but struggling to easily return where a switch was added to via the API. For context, I have added 1800 switches into DNAC. I would like to verify they have been added to the correct hierarchy but not sure how to best go about this. 

api_.devices.get_network_device_by_ip will show me that it has been added but the location or locationName keys are blank even though a switch has been properly assigned. As a workaround, I can locate the site_id it is in and pull all the devices of the building via response = api_.sites.get_membership(site_id) then loop through the results to check if it exists but this seems extreme. 

Any tips or advice would be greatly appreciated.

Regards.

This was a known issue with the /network-device API in the existing DNAC releases. You can use "Get Device Detail", it should provide the location.

Thanks bigevilbeard! Much appreciated. I noticed that get_device_detail provides a weird output for switches that are not being managed correctly even though assigned to the correct area/building. Not the end of the world but wondering if you've seen this before. Here's a switch that was added to DNAC but not managed due to credentials not matching the global setting.

When I query the API for this switch, it does not provide the location but the following response:

{'response': {'location': '--', 'timestamp': 1685995080000}}

 I am guessing the solution is to fix the switch so it is managed properly but thought I would mention it anyways. I suspect the only option for these would be to proceed with what I mentioned previously. Use api_.sites.get_membership(site_id) then loop through the results to check if the IP exists.

Thanks again for taking to the time to response.
