Remove HTTP(s) write credentials from device with DNA center

[Concepts L5]

I am new to the DNA Center and incorrectly created a set of HTTP(s) write credentials in Design-Network Settings-> Device Credentials. I then applied these credentials to a site and they got pushed to a 9200L switch and a 9800-40 WLC. The DNA Center will not let me delete these credentials

"NCIM01100: Credential deletion failed. Reason : Credential https creds is associated with Network Settings for site - X. You must either associate a different credential or create a new credential of the same type and associate it with the site, prior to deletion.""

I do not want to use HTTP(S) write  credentials in my environment at all.

Is there a way to unapply these credentials to the site ?

How do I remove the HTTP(S) write credentials ?

and what configuration changes did this make to my devices that I now have to undo

Hi

 The configuration is the same as if you were enable HTTP in a  Cisco switch. Create a user, enable HTTP server and probably configure a source interface. 

  To remove, I believe you need to re-discovery the devices but this time dont enable HTTP on the Devices Credential page. Keep only CLI and SNMP.

Once a credential is assigned to a Site, you cannot remove that credential from the Network Settings. As mentioned in the Error message:

"You must either associate a different credential or create a new credential of the same type and associate it with the site, prior to deletion."

The Credentials are applied to a device thru:
* Discovery of Network Device (the selected credentials are used and configured if needed)
* Applied to Site and then provisioning of the network device(s) that are assigned to site.

If you applied the credentials to a site and then provisioned the network devices in that site, you will need to manually remove or use a template to remove the credentials from devices.

In order to remove assigned credentials from the Cisco DNA Center UI & DB, manual steps are needed to remove from the Cisco DNA Center Database. You will need to Contact the Cisco TAC Support for assistance on this.
