Section 3 - Viewing Access Point Status
A TSPEC is a traffic specification that is sent from a QoS-capable wireless client to an AP requesting a certain
amount of network access for the traffic stream (TS) it represents. A traffic stream is a collection of data packets
identified by the wireless client as belonging to a particular user priority. An example of a voice traffic stream is a Wi-Fi
CERTIFIED™ telephone handset that marks its codec-generated data packets as voice priority traffic. An example of
a video traffic stream is a video player application on a wireless laptop that prioritizes a video conference feed from a
corporate server.
To view TSPEC client association statistics, click the
