I do agree with Martin. Coming from years of using HP switches, there are some things that Ruckus ICX switches seem to make overly complicated. I'll state for the record these things are rock solid and once they're set up they just work, but Ruckus could learn a thing or two from the ease of managing and initial setup of HP Procurves.
That said, I was able to get loop detection to work on the ICX switch and it is acceptable.
