The Wi-Fi MDM payload is used to configure wireless network settings on Apple devices. For macOS, this payload contains the QoSMarkingPolicy key, which can be set to Cisco to enable Cisco Fastlane. This setting allows the Mac to apply appropriate Quality of Service (QoS) markings to Wi-Fi traffic for applications. A compatible Cisco wireless network can then use these markings to prioritize critical traffic, such as voice and video, ensuring optimal performance for real-time applications.

A. VPN: The VPN payload configures settings for secure network tunneling and does not include parameters for Layer 2 Wi-Fi QoS marking like Cisco Fastlane.

B. Restrictions: The Restrictions payload is used to enforce device policies and disable specific functionalities; it does not manage network traffic prioritization.

D. Network Usage Rules: This payload defines which applications can use specific network interfaces (e.g., cellular data), not how traffic is prioritized on a Wi-Fi network.
