Following an upgrade from 200.0.9.9.608 to 200.4.9.13.47 I am no longer able to connect to the AAA server used for RADUIS/802.1X network auth. The AAA server is on a different subnet to the Access points. I can connect to the AAA server on radius port from other devices on the same network as the Ruckus Access points, just not from the Ruckus devices.
A ping from the Ruckus devices shows request time out and a trace route show the request taking a patch via a non-existent IP address. I've had to disable 802.1X until we can get this resolved.
What's happened and how can I make it work? I can't even see a way to roll back the firmware to the one that worked.
