How to verify scan rejects when VoIP aware or Video aware scan is enabled in ARM?

Q:

How to verify scan rejects when VoIP aware or Video aware scan is enabled in ARM? 



A:

When VoIP aware or Video aware scan is enabled on the ARM profile, the AP will reject ARM scan requests when there is an active voice or video traffic through the AP. 


This can be verified by the increase in the "Voice aware Scan Rejects" and "Video aware Scan Rejects" counters in the radio-stats of an AP. 


Run the command "show ap debug radio-stats ap-name <AP-NAME> radio 0 advanced | include can" every few seconds to check the increase in the counters. This will be useful in troubleshooting voice or video related issues. 


Below is an example output collected when there is an active voice call where the "Voice aware Scan Rejects" are being increased,
