My primary C5210 lost network connectivity this morning, and it appears that my failover went sour. When things transitioned to my backup C5210, all of my sites were there, but the AP assignments were lost.
It took me a while to figure out what the issue was, and now that I have corrected everything, I am afraid to transition back to the primary for fear of losing my site to AP assignments again. I have the "Synchronized" box checked for all my site configurations. And the last time I did a failover, this did not happen. But it was a planned transition in perfect network conditions.
Are there any noted cases of this happening? Perhaps it's a bug or expected behavior.
I am running firmware 10.31.01.0048.
