Refer to the exhibit.

The exhibit creates WLAN profileguest-networkwith WLAN ID20and enables web authentication, but it does not yet define the client VLAN or bind the WLAN to a deployable policy. On Catalyst 9800 controllers, the WLAN profile defines SSID and wireless/security characteristics, while thepolicy profiledefines client-facing network policy, including VLAN assignment, AAA, ACLs, and switching behavior. Cisco’s web authentication configuration guide states that the policy profile specifies client VLAN, AAA, ACLs, timeout settings, and related policy, and the VLAN is assigned under the policy profile.

The second required object is thepolicy tag, because a policy tag maps the WLAN profile to the policy profile. Cisco also notes that the default policy tag automatically maps only WLAN IDs1 through 16; WLAN ID17 or highercannot use that default mapping. Since this WLAN is ID 20, a custom policy tag mapping is required. Mesh bridging, STP, AP group naming, or physical-interface isolation do not complete the Catalyst 9800 WLAN-to-VLAN policy model.
