The Wi-Fi system architecture using Hyperion series WLC and Thin APs is illustrated below.
Figure 3-1 Wi-Fi System Architecture using WLC
The WLC has a southbound interface named the WLAN port. This port is the accessing port for all Thin APs connecting
to WLC
;
while the northbound ports based on WLC internal VLAN Interfaces (VIF) connect to the Portal / Radius for user
authentication and Internet for user services.
Two types of tunnel are established from Thin AP to WLC and will take charge of all communications:
The CAPWAP tunnel, an access stratum management tunnel, focuses on provisioning AP and all statistics
reports.
The WLTP data tunnel focuses on UE (User Endpoint) non-access stratum data transmission, including service
traffic and authentication messages.
