I have a Cisco WLC 5508 that is not performing L2 (intra controller) roaming between my APs.  Where exactly in the interface can you view/adjust such settings?

How exactly do you mean its not working?  If two APs broadcast the same SSID roaming just works.

There are thresholds to consider though.  For example, if you put two APs on a table, on different channels, a client would probably only ever associate to one as the received signal and SNR would be roughly the same, so the client would never see the other AP with a better signal.

I've only used the non controller aps, but for them I would disable the lower data rates, set a fairly high data rate to basic, set the higher ones to enabled so that the client computers would switch ap associations faster. I assume you have the same functionality in the wlc somewhere

On my WLC5500, I changed the roaming setting from Auto to Custom, but left the default settings.  After that, roaming started working.  Strange.  You would think that the Auto setting would have worked.  I know it worked on my old 4400.
