I'm not sure if Smartzone has a built in URL/WEB filtering already. if yes, why I have to buy an additional subscription license for URL/WEB filtering feature?
We do L7 without requiring a license but yes the URL/Web filtering requires a license per # of APs. This means that if you have a zone where you require URL/Web filtering, you purchase the amount required instead of the total amount of APs on the controller.
