Generate Report for Traffic Stream Metrics in WCS

[cjunhan99]

Hi Cisco Support,

We tried to generate report for Traffic Stream Metric in WCS but got the error as follows:

Traffic Stream Metrics
Generated: Wed Nov 24 18:24:37 SGT 2010
Report By: AP By Controller
Protocol: 802.11a/n;802.11b/g/n
Reporting Period: Last 1 hour
The specified criteria did not match any data for the report. Make sure that the following background tasks are running: 1.Traffic Stream Metrics 2.Radio Performance

How could we resolve this issue?

Please refer to attached and need your kind assistance.

Thanks.

Hi Junhan,

Can you make sure on the controller under Wireless > 802.1a/n and 802.1b/g/n > Voice that you have metrics 
collection checked because  Traffic Stream Metrics are for phones since it covers jitter, tx and rx amounts etc.  

This is the reason it has to be on voice enabled controllers.  You will not see it for clients. if you have

clients are desktop and laptop wireless devices then we will not get anything.

thanks,

Vinay

Hi Vinay,

I tried to enable Traffic Stream Metric under Wireless > 802.1a/n and 802.1b/g/n > Voice already in WLC but when i try to generate the report via WCS still shown as follows:

The specified criteria did not match any data for the report.

Make sure that the following background tasks are running:

1.Traffic Stream Metrics
2.Radio Performance

What would be the cause?

Thank You.
