In this case, the frames are recorded that were received and sent by the device.
Exception: The frames dealt with directly by the hardware are not displayed, for example
hardware repetitions, acknowledgment frames.
The access point sends no more frames but records all incoming frames.
Note
No WLAN communication between access point and clients
If the setting "All Traffic" is used, the access point is no longer reachable for other nodes
and loses the connected clients.
After a restart the configuration is rest to the default settings.
The configuration is saved and retained after a restart.
