what is happening or where i do wrong? other controller are working fine.

           - I presume the mac address being tracked is effectively using the controller or trying to?
           - Is the software version perhaps different compared to the other controllers ?

using same commands...

17.3.6 + 17.9.4a OK.

17.9.5 cannot.

[marce1000]

                                            >....17.9.5 cannot.
  - Try with a few other mac addresses too , to make sure that there was no accidental mistake when typing the content
     of a particular mac address and to make sure that the problem 'is steady'

no. i confirmed it's not typo error as i repeated the same command and double verified.

found this which is similiar but no solution.

C9600X Stackwise Virtual Active Failing to Show FED Traces  CSCwj56654 

[Haydn Andrews]

Try the radio active trace via the GUI and ensure logging enabled in there. Find it easier anyway cause I can just download the tracefile post it running

[JPavonM]

Cisco has modified some logging behaviour in the last codes, something that it was working before is not working in 17.9.4 and 17.9.5 like "monitor logging profile wireless mac <MAC>" is not producing any output now, unless you enabled "service internal" in config mode before.

They are making this change to avoid resource starvation during logging, and they recommend to disable it after the debug.

Try if this fixes your RA tracking issue in the console as well.
