Wireless Access

Hi,

I would be happy if someone could clarify below queries :

We have configured WMM on controller for specific SSID (Voice SSID for spectralink phones) and configured WMM DSCP mapping for voice 46 and for video 40 ...

and configured end to end QoS in LAN

query 1 : how do i verify that marking is been trusted on controller ?

Iquery 2 :  came across below show command output  and concern about mapping

As I understood from above output is , WMM 6 is been mapped with 40 but i am expecting 6 should map to 46 ....

what could be the issue ? or am i  looking in output wrong way ?

Thanks

Have you done a packet capture and see hows the client sending this marking ?

If you want re-mark the frame at the controller firewall level or overwrite thw WMM at the SSID level ?

Hi,

Well, I have not done packet cappture yet however i could see hits on switch side ( core switch - AP connected port with show command )

show mls qos interface < interface ID > statistics

please find below output of show wlan ssid-profile

show wlan ssid-profile < abcVoice >

Hi ,

Can anybody look into this and let me know the right approach for this query to resolve or get right options to troubleshoot ?

Victor,

I am working on a project and appear to be in the same situation you were in previously.  Were you able to find an answer to your question?  

One command I was given is "show ap debug client-stats", but the numbers for the WMM entries, which I assume to represent number of frames is significantly lower than the actual number of frames transmitted, and a large number of frames show as Rx BE, despite confirming (via wireless captures) nearly all WMM marked frames are set to 6 (Video).  

Thanks

can you share the SSID profile configuration and the user role details:

show wlan ssid-profile <Name-of-Profile>

show rights <Name-of-User-Role>
