I agree, the WiSM/WLC docs are unimpressive. This FAQ has some useful bit and pieces: http://cisco.com/en/US/customer/products/ps6366/products_qanda_item09186a008064a991.shtml
Note that Cisco has recently re-engineered the radio resource management (RRM) system to make it more stable. You need recent code to get the latest fixes (we're running 4.1.185.0). This doc explains how RRM works in detail: http://www.cisco.com/en/US/tech/tk722/tk809/technologies_tech_note09186a008072c759.shtml If you have the Wireless Control Server then you can run reports on channel and power changes for all APs known to the controllers and that can show you how things are working WRT to RF channel assignments and power levels in RRM. Be aware that even with the new RRM system the channels can repeatedly change due to anything that RRM regards as excessive external interference. After I lost my connection on my Dell laptop at every Friday morning staff meeting I found that it was due to the microwave oven down the hall being used to heat breakfast. (My laptop has a pretty common setup: WinXP with Intel PRO/Wireless 2200BG NIC with current OS and NIC patch levels.) Other staffers at the meeting didn't notice the change from chan 1 to 11. Presumably their NICs and drivers were better at maintaining a connection and following the channel. However, rather than risk other users on campus losing their connections due to the "microwave burrito effect" we decided to tell RRM to chill out on the channel changes and modified the RRM channel change behavior on all WLCs to occur only once per 24 hours at 3 am. The new code makes this easy to configure, but the commands to do so are in the release notes and haven't made it into the main docs as yet. -Charles Charles E.
