The 802.11e TSPEC (Traffic Specification) provides a set of parameters that define the characteristics of the traffic stream, (operating requirement and scheduling etc.). The sender's TSPEC specifies parameters available within packet flows. Both sender and the receiver use TSPEC.

The TSPEC screen provides the information about TSPEC counts and TSPEC types utilized by the selected wireless client.

To view the TSPEC statistics:

  1. Select the Statistics menu from the Web UI.
  2. Select System from the navigation pane (on the left-hand side of the screen). Expand an RF Domain, select a controller, an access point, then a connected client.
  3. Select WMM TPSEC.
    The Statistics > Wireless Client > WMM TPSEC screen is displayed.
    Click to expand in new window

    The top portion of the screen displays the TSPEC stream type and whether the client has roamed.

    The Ports Stats field displays the following:
    Sequence Number

    Lists the system assigned sequence number that's unique to this WMM TPSEC uplink or downlink data stream.

    Direction Type

    Displays whether the WMM TPSEC data stream is in the uplink or downlink direction.

    Request Time

    Lists each sequence number's request time for WMM TPSEC traffic in the specified direction. This is time allotted for a request before packets are actually sent.

    Used Time

    Displays the time the client used TSPEC. The client sends a DELTS (delete traffic stream) message when it has finished communicating.


    Displays the parameter for defining the traffic stream. TID identifies data packets as belonging to a unique traffic stream.

  4. Periodically, select Refresh to update the screen to its latest values.
