It seems that all of our controllers are flakey running any version of 6.x but our 3200 seems to be the worst.
We were previously running 5.0.3.3 and our 3200 controller ran great. All the devices stayed connected. We upgraded to version 6.2.1.4 because of new devices that required version 6.x. We also upgraded the memory per Aruba support. Ever since then the controller has been unstable. We monitor all our devices using SolarWinds and we see the controller go down randomly. During this time, we may or may not be able to get to the controller. Most of the time when the controller is responding again all the devices connect back up. Every once in a while the devices will not come back up and show as dirty. If I make a change on the controller, such as enable and then disable spanning tree, everything comes back up.
We have had support look at the controller and our network configuration. They made some minor changes but it only seemed to help for a couple of days.
The controller says that it has not gone down and support says they could not find anything in the logs saying that it lost connection..
Any ideas of where to look?
Thanks,
Larry
