Hi Kristofer,
We do not have a document that shows the difference between Partner Brand and Cisco Brand. The partners do not sell Cisco partner brand but create their own service offer to support their end customers. They then back that service off to Cisco where they need support using Partner Brand. From a Cisco view in Partner Brand we support the Partner, with Cisco Brand we support the end customer. If you had Cisco brand (SNTC) then you would work directly with Cisco Technical Assistance Center (TAC) for support on any network issue.
When uploading data to Cisco you would not be able to do that without first registering the collector with a Cisco service such as SNTC. That would certainly cause an error but I do not know exactly where "System Description is missing" is coming from.
For Installed Base management you could try to use My Devices. My Devices is an online tool that lets you build and manage a list of the Cisco products you own. It provides a reference for device information that includes:
Product ID, category, and model
Product release date
End-of-sale and end-of-support dates
Support contract type and expiration date
Warranty type and expiration date
Location where the product is installed (based on Contract data)
To add a device, you only need to enter its serial number in the portal. You can do this individually or using a bulk upload. You must have a valid Cisco.com account to use My Devices and the account must have an associated Service Contract.
You can access My Devices from the Cisco Support page. In the My Support area, expand the Devices heading and click My Devices.
Hope this helps you get started.
Regards, Tim
