So I have a stack of 2 x Catalyst 9300 and 2 x C9300-DNA-E-48= licenses.
I'm a bit confused on how to activate these licenses. Everything clear with the old ones, but the new versions, are just RTU ?
Please follow the below snippet, taken from this url:
Licensing and ordering
To enable the Cisco DNA Center features listed in Tables 1 and 3, you will need one Cisco DNA Essentials or Cisco DNA Advantage license for each network device. Both of these licenses are available for purchase with Cisco ONE™ Software or a la carte. Please contact your Cisco sales representative for the Cisco DNA Center Ordering Guide.
See how Cisco ONE makes software buying simple: Cisco One Software.
