Funny though, it seems that you can access the file directly: Design and Deployment of Enterprise WLANs (BRKEWN-2010) http://d2zmdbbm9feqrf.cloudfront.net/2012/usa/pdf/BRKEWN-2010.pdf Cisco has the most technical content available, compared to any other network vendor that I am aware of.

Can you say more about Cisco's recommendations on that? Or are they simply saying /21 is the maximum recommended size? I'd also be interested in anything they said about mcast as it relates to size. I've setup vlan select on a test WLAN with the intent of breaking up my /21 into smaller pieces for the fall, but I've had no problems with it (though mcast is off). But I thought I would use smaller subnets since our wireless use has gone up quite a bit in recent years and doing it is so simple to do now. I've heard conflicting info, and to my surprise one time a TAC engineer suggested they should be no larger than /24, which I think is erroneous.
