The Cisco OfficeExtend Access Point (OEAP) feature is enabled on a Cisco Catalyst 9800 Series Wireless Controller through the Flex Profile. The Flex Profile allows for the configuration of various settings specific to FlexConnect deployments, including OEAP settings, which enable remote workers to connect to the corporate network securely.

Cisco documentation on Catalyst 9800 Series Wireless Controllers

When a wireless controller is configured to authenticate clients against Microsoft Active Directory using PEAP (Protected Extensible Authentication Protocol), it uses RADIUS (Remote Authentication Dial-In User Service) as the protocol to communicate with the authentication server. RADIUS is a networking protocol that provides centralized Authentication, Authorization, and Accounting (AAA) management for users who connect and use a network service.

 The two protocols used to communicate between the Cisco Mobility Services Engine (MSE) and the Cisco Prime Infrastructure network management software are HTTPS and NMSP (Network Mobility Services Protocol). HTTPS is used for secure web-based communications, while NMSP is a Cisco proprietary protocol used specifically for efficient, real-time communication between MSE and network management software like Cisco Prime Infrastructure. References := (CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide)

Enabling unicast AP multicast mode can correct the issue of increased controller CPU overhead and overall network utilization after multicast is enabled. This mode allows the controller to send multicast traffic to the APs as unicast, which is more efficient for the wireless medium and reduces the load on the controller’s CPU.
