@NightShade1 - the LB related answer was to address 'fn's query on - '...but with all my efforts no single lb move'.

Here's how sticky client works,
The client's SNR (as monitored by the AP) is supposed to be a minimum of atleast </= 25dB SNR (default value) in order for this
particular steer type to get implemented. Additionally, the client has to be able to hear a neighbor AP at a minimum of -70dBm SNR and also the neighbor AP SNR must be a minimum of 10dB greater than the client's existing SNR.
ONLY if all these three parameters match, the client will get steered due to sticky client.
However, the good news is that all of these values are configurable in the ARM profile.
You may have to calibrate the ARM settings of the test environment (using these values as a baseline) depending on what criteria you want the controller to steer the client due to sticky behavior. Theoretically, there would be no situation where the sticky move is not completed, as long as the values are matched as per the design, neighbor/client SNR and follows the logic mentioned above.

With this command, (where, T = Total & S = Successful) you would be able to check whether the login is getting triggered for the specific client mac, although it has not been successful. You'll have to use the debugging command i mentioned above to get more granular details on which exact factor it has failed.

cm-sticky-min-signal - Client Match Sticky Min Signal Level required for
target AP ( -dBm)
cm-sticky-snr - SNR of client that triggers sticky move(dB)
cm-sticky-snr-delta - Min SNR improvement between current AP and desired
target AP (dB) for sticky move
Here are the default values of these config parameters:
Client Match Sticky Min Signal 70
Client Match Sticky client check SNR (dB) 25
Client Match SNR threshold(dB) 10
