To enable packet capture on an
      AP:
        
        - 
                Go to .
            
- 
                Select an access point (not the check box).
            
- 
                Select .
            
- 
                Configure the packet capture parameters. 
            
- 
                Click Start to start the packet capture.
            
- 
                Click Stop to stop the
                packet capture.
                Packet capture stops when
                    capture duration is reached or capture file size reaches 1GB. 
- 
                Click Active Packet
                        Captures to display a dashboard that shows the Packet
                        Capture Instances widget. The widget lists recent packet capture
                    instances. Active instances display in green and inactive instances display in
                    red. Inactive instances are eventually removed from the widget.
                The file name is automatically
                    generated. The name is based on the AP or site where the capture was initiated
                    plus an internal capture ID. 
- 
                Hover over the capture file and
                    select Download to download the file.
