TSPEC Client Associations
The TSPEC Client Associations page provides real-time information about the
TSPEC client data transmitted and received by this access point. The tables on
the TSPEC Client Associations page show voice and video packets transmitted
and received since the association started, along with status information.
A TSPEC is a traffic specification that is sent from a QoS-capable wireless client to
a WAP device 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, select Status and Statistics > TSPEC
