yes, we are able to see all the Accesspoints, but the clients are getting associated with only two AP's which are IAP 105 rest of the AP's in the cluster are IAP 93 model.
We had done a recent Upgrade from 6.2.0.0-3.2.0.0_36559 to 6.4.2.6-4.1.1.6_50009 and only after the upgrade we see these issues.
As a workaround we had downgarded the firmware post which we could see the clients getting associated with all the AP's.
