 To adjust the precedence and override the QoS profile on the WLAN for WebEx, an Application Visibility and Control (AVC) profile needs to be created for WebEx. AVC profiles allow for the identification and prioritization of specific applications over the wireless network, ensuring that critical applications like WebEx receive the necessary bandwidth and QoS treatment. References := CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide
