Huawei’s free mobility solution enhances user authentication and access control by synchronizing IP-security group entries across devices, ensuring seamless policy enforcement. The HCSP-Presales-Campus Network Planning and Design V1.0 documentation specifies:

Switches: Campus switches (e.g., CloudEngine series) can act as access devices, authenticating terminals via methods like 802.1X or MAC authentication. They support IP-security group synchronization to enforce consistent policies.

APs (Access Points): Wireless APs (e.g., AirEngine series) serve as access devices in WLAN scenarios, authenticating terminals via 802.1X, portal, or MAC methods. They also participate in IP-security group synchronization for mobility.

AR (Access Routers): While AR routers (e.g., NetEngine AR series) can perform authentication in certain contexts, they are typically not access devices in the free mobility solution’s context, focusing instead on routing and WAN functions.
