I've inherited a couple 4402 Wireless LAN Controllers and am in charge of getting them ship-shape. While I have some general knowledge of wireless, I have not worked with wireless controllers before and have a couple questions I was wondering if anyone could help me with:
1) How can I verify that the primary and secondary controllers are configured for failover without actually performing a test? Both do have AP Failback enabled, but I'm not sure what else to check.
2) They are currently running code 188.8.131.52. Should I stick with 3.2 or plan to move up to 4.X?
Thanks a bunch. I'm slowly working my way through the docs and answers to these would sure speed things up.
Hope things are well with you! The steps required to configure AP Fallback are detailed quite nicely in the attached doc. I would always try to schedule a Maintenance window to test this out rather than not knowing for sure :)

Now, for your second question, it's likely that you will want to upgrade the WLC to a newer version of code. They have gone through 4.0.x,4.1.x and the newest is 4.2.x. So 3.2 is a fair ways behind. Have a look at the WLC Release Notes;

Hope this helps!
