Hello everyone,
I wanted to post this incase anyone else runs into the same issue. We've been running Aruba OS 6.1.3.2-airgroup for several months without any major problems. After upgrading to 6.4.0.1, all of our HP AirPrint printers stop communicating with the controller after about 20-30 minutes. We would have to restart each of them to become visible again. But sure enough, a short time later, they would stop working. Note that this problem happens in OS 6.3 as well.
I reported this to Aruba and apparently it's a known bug that engineering is working on. Here is the response I received from Aruba:
Confirmed Nathan that the issue is a known issue. Reported to the Engineering team with ID 85098.
Explanation:
1) HP printer initially responds to all the requests from controller, however later it stops responding. So users are not able to reach the printer. After AAA idle timeout the printer is removed from the controller entry..
Next Action changed to:
customer roll back's the controller to previous code version. Case can be closed.
