Hi,
Thank you for posting in Q&A!
Following is a guide on how to have Microsoft Active Directory user accounts in a security group authenticate to Cisco gear.
https://mrickert.com/2017/08/03/authenticate-ad-users-on-cisco-switches-through-radius/
First add the cisco switch as a radius client, and create a new network policy.
Add your already created Windows AD security group and ok out of the prompts.
After configuring this NPS plociy for AD security group, configure the same on a local users group.
Hope you have a nice day : )
Gloria
