Aruba Instant comes free of additional licenses so AppRF is included without an additional license.
The second part of your question, WebCC, is a subscription, that allows access to the Web classification database. You will need to purchase a subscription if you are using that.
In order to use WebCC on Aruba Instant, you need either:
- Aruba Central (Cloud Management)
- Cloud Web Policy Enforcement (JW455AAE Aruba SUB1-WE-IAP-1 for 1 Instant AP 1-year Subscription). There are 3 and 5-year equivalents of that subscription available as well.
So if you have Aruba Central, the WebCC is included in that subscription.
