Controllers typically map WLANs to VLANs. When configuring a switch port to a controller, you would set the port to support 802.1Q (switchport trunk encapsulation dot1q), then set the port to trunk (switchport mode trunk) and only allow the VLANs needed by the controller (for example, switchport trunk allowed VLANs 10,20,30 if your controller needs only VLANs 10, 20, and 30).
