You need to configure and maintain WLAN features and functions in different profiles. These WLAN profiles include regulatory domain profile, radio profile, VAP profile, AP system profile, AP wired port profile, WIDS profile, WDS profile, and Mesh profile. When configuring WLAN services, you need to set related parameters in the WLAN profiles and bind the profiles to the AP group or APs. Then the configuration is automatically delivered to and takes effect on the APs. WLAN profiles can reference one another; therefore, you need to know the relationships among the profiles before configuring them. For details about the profile relationships and their basic configuration procedure, see WLAN Service Configuration Procedure.
A school plans to deploy a WLAN to cover its dormitory building. However, the dormitory building has a high density of rooms, and WLAN signals are likely to attenuate severely when passing through obstacles between rooms, such as walls.
As shown in Figure 1, the AC connects to a central AP through the switch, and the central AP connects to and supplies PoE power for remote units (RUs). All RUs (one for each room) and the central AP are uniformly managed by the AC to provide a high-quality WLAN.
The configuration roadmap is as follows:

Configure port isolation on the interfaces of the device directly connected to APs. If port isolation is not configured and direct forwarding is used, a large number of unnecessary broadcast packets may be generated in the VLAN, blocking the network and degrading user experience.
In tunnel forwarding mode, the management VLAN and service VLAN cannot be the same. Only packets from the management VLAN are transmitted between the AC and APs. Packets from the service VLAN are not allowed between the AC and APs.
