TSPEC Client Associations
The TSPEC Client Association Status and Statistics page provides information
about the TSPEC client data transmitted and received by this access point. Table
10 shows voice and video packets transmitted and received by the association,
along with status information.
The page shows a real-time display of transmit and receive statistics for the
TSPEC clients. All transmit and receive statistics shown are totals since the client
association started.
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 System Status > TSPEC Client
Associations tab.
