Why each option

On the Catalyst 9800 WLC, AVC for deep-packet inspection providing per-client application usage details must be enabled at the WLAN level, not in tags or policy profiles.

AAP join tag

The AP join tag maps an AP to a site tag, policy tag, and RF tag - it contains no AVC or application inspection configuration.

Bpolicy profile

The policy profile governs client session parameters such as VLAN assignment, QoS, and security policy but is not where AVC deep-packet inspection is enabled for client visibility.

CRF tag

The RF tag controls radio resource management and band-specific radio settings and has no role in application traffic inspection or AVC policy.

DWLANCorrect

AVC is enabled directly on the WLAN configuration on the Catalyst 9800 WLC to activate deep-packet inspection for all clients associated with that SSID. Configuring AVC at the WLAN level ensures the inspection engine processes traffic for every client on that WLAN and collects detailed per-client application visibility data, which is the data source used to meet the customer's reporting requirement.
