Compatibility and licensing notes

This controller works with supported Cisco lightweight access points, not standalone autonomous APs. Confirm the exact access-point model, regulatory domain and controller software compatibility before purchase. The AIR-CT2504-5-K9 SKU represents the five-AP license tier; upgrade licenses are separate. DTLS encryption for certain OfficeExtend deployments may require a separate license, depending on the intended configuration.
