Hello, We are going to build an SDA LAB and for that, we have Cisco 9300 and Cisco 3850 switches. In the 9300 the licenses are already SDA capable (Network advantage/Essential) but in 3850 the license level is normal IP services and here we need an "Add-on" license to activate the SDA capabilities for these switches. I have the recommended 16.6.4 IOS-XE image on the 3850s as described in the SDA compatibility matrix. ''https://www.cisco.com/c/en/us/solutions/enterprise-networks/software-defined-access/compatibility-matrix.html'' As shown in the screenshot also, I could not find a way to activate the add-on license, in fact, I cannot find any add-on license at all. Does anyone know how to activate the add-on license or how to install them? where to get them from? Any information will be appreciated, Thanks a lot.   ... View more
