Thanks again Matt! What controllers are you using? With the one vlan on all 5 controllers did you still need to implement an inter-controller roaming domain?
Thanks again so much for your time!

The highest simultaneous count I have seen is around 1600. We are typically somewhere between 1000 and 1500 (we have around 3,300 students), but that has been rising. We will probably hit well over 1700 in the fall semester. More and more students are coming in with iPod Touches and such in addition to having a laptop.

It is very nice to have the one subnet that covers everywhere.

We probably don't need quite that big a space right now, probably a /22 at most. I am doing some capturing right on the controller as well and am seeing similar stuff. Only arp's and some DHCP broadcasts. Are you spreading the /20 around to multiple controllers as well? We currently have 3 controllers and I am also considering inter-controller roaming, but if we do a /22 on all controllers I will get layer 3 mobility anyway.

I only see ARP traffic for the router in that subnet and traffic coming straight to me. I don't see any other broadcasts at all. I do packet captures fairly often and never see broadcasts that I shouldn't. Our big student wireless subnet is currently a /20 and we have no issues with that.

Looking at some of my packet captures the broadcast traffic seems to be limited but I do see some broadcasted DHCP packets. I know they claim to do some suppression according to the config guide. It doesn't seem as cut and dry though as compared to how Cisco's WLC's do it. We are looking to possibly expand the size of our subnets for wireless and this plays into that. What are some of the subnet sizes that some of you are using for WLAN? Thanks!
