Range of values / note
● all-traffic (access point only)
Note
In this mode the access point sends no more frames but
records all incoming frames. This means that the access point
is no longer reachable for other nodes and loses the
connected clients.
● own-traffic
Note
In this case, the frames are recorded that are received and
sent by the device.
Exception: The frames dealt with directly by the hardware are
not displayed, for example hardware repetitions,
acknowledgment frames.
