Off of 6 WiSMs we have two /20's shared and another /21 shared with no issues as of yet.
Walt-- I am curious, is this the "P2P Blocking" that is set at the SSID level? We have thought about this in the past but have yet to turn it on.

In our setup, multicast and broadcast packets are disabled on the wireless VLANS so the large size is not an issue. This was actually a nice feature of the controller. Broadcast traffic that needs to work (ARP, etc) gets answered by the controller and everything else (windows file sharing, etc) gets dropped. We don't have any applications that we support on wireless that require broadcast or multicast so this was an easy choice.

Currently running a 22 bit mask for the 1022 hosts on one SSID/VLAN. Would welcome any real world experience about increasing to a 21 bit mask for the 2046 hosts or larger on one SSID/VLAN with Cisco WLCs and lwaps.
