ccorrect AVC profile mapped to WLAN has a rule for MARK or DROP action. https://www.cisco.com/c/en/us/td/docs/wireless/controller/technotes/8-8/AVC_8point8_dg.html

To prioritize Cisco IP cameras using Cisco AVC (Application Visibility and Control) on a Cisco Wireless LAN Controller (WLC), the mark element is configured in a rule. Here’s why: Mark: The mark action in an AVC rule allows you to apply a QoS marking (e.g., DSCP or UP) to the traffic that matches the rule. For Cisco IP cameras, you can create an AVC rule to identify the traffic and mark it with a high-priority QoS value (e.g., Platinum for video traffic). This ensures that the IP camera traffic is prioritized on the wireless network. How it works: AVC uses deep packet inspection (DPI) to identify specific applications or traffic types. Once the traffic is identified, the mark action applies the appropriate QoS marking to ensure proper prioritization.

NBAR Supported Feature NBAR as a feature can perform the following tasks: 1. Classification–Identification of Application/Protocol. 2. AVC–Provides visibility of classified traffic and also gives an option to control the same using Drop or Mark (DSCP) action. 3. NetFlow–Updating NBAR stats to NetFlow collector like Cisco Prime Assurance Manager (PAM). https://www.cisco.com/c/en/us/td/docs/wireless/controller/technotes/8-8/AVC_8point8_dg.html
