Quick review of Cisco DNAC

We have a first generation appliance and have it in our lab/staging environment. Currently, we are using the 1.2.10 version of the DNA Center software. I would say that the initial installation was difficult with issues getting the 10GE Enterprise Port connected to a DC Catalyst 3850 Switch. We tried Trunk and Access mode and two different Cisco switches and could not get that port up and running. We finally got the appliance setup via 1GE port but being a lab that was fine. We will most likely re-image the box when 1.3 becomes available. On the whole I like DNAC with features like software image management and Assurance being invaluable to a network engineer. Once you get Cisco ISE integrated you can get full analytics and telemetry information based on identity across the network. SDA or Software Defined Access is a new way or even a paradigm shift in creating a campus LAN. It requires full Cisco ISE integration utilizing SGT's for user/device on-boarding. I really like the fact that a policy applies to that user or device no matter where or how they connect to the network. I would say that extending a fabric to other sites say over a WAN is still kind of a gray area with little documentation or best practices available yet.
