Hello, I'm sorry, but I simply can not find a clear answer to my question beyond pages and pages of Cisco marketing lingo. I understand with some products, for instance Catalyst 9000 series switches, a Cisco DNA subscription license is required. We currently do not use Cisco DNA Center so my question is, what is the point of requiring the DNA subscription license? What benefit does it give me if I am not using DNA Center? Is the sole purpose for software upgrades (which SmartNet could just as well give me) or is there an actual feature or service that is accessible with the license? That is like the most basic question but I can not find the answer! Thanks!
