Traffic Stream Metrics (Tsm) - Cisco 9971 Deployment Manual

As of the 9.0(2) release, the Current Access Point information can also be seen in the phone's web interface.

Traffic Stream Metrics (TSM)

The Traffic Stream Metrics feature requires the client to report voice traffic related measurements to the AP.
The parameters (queue delay, media delay, packet loss, packet count, roaming delay, roaming count) will be gathered by the AP
and escalated to the WLAN management system, which will help maintain a database that can be used for the benefit of the
stations by ensuring low packet latency and loss.
Check the box "Metrics Collection" in the global 802.11 Voice Parameters to enable Traffic Stream Metrics.
See the "Call Admission Control Settings" section for further information on how to enable TSM.
To view Traffic Stream Metrics data for a client, select TSM from the drop down menu for which band the Cisco Unified IP
Phone 9971 is using.
The Traffic Stream Metrics data entries will then be displayed.
