In our residential halls we've deployed dual-radio 802.11n AP's at a level
where we average no more than 10 people per AP. Moving forward, our new
residential halls will move to an AP per suite, pushing the average to no more
than about 6. At our peak demand per day, our campus client-per-AP
Are the AP's getting their IP addresses from a DHCP server, and if so, do IP
renewals at all correlate to the AP dropping the CAPWAP session?

Assuming you are running some form of n+1 redundancy with your controllers, then the loss of a single 500-1000 AP controllerwould be minimal.

When the 5500 series were under development, 10GB was still very rare. I
remember having a conversation with the project lead, and while I had the same
concern about the lack of 10GB, I came away thinking they had made the right
choice. Now that I've lived with the 5508s, I've yet to see
The datacenter licensing also applies to VMware i.e. if you license it
for all of your processors, you can run an unlimited number of virtual

So if you have a dense deployment of AP's, then leaving the lower rates enabled
should not present an issue - at least I've not seen one. Additionally, as my
campus is 75% Macintosh, they tend to connect at 5GHz, so I don't mind having
the lower rates enabled in 2.4GHz to help out all the
If the system is designed for performance and redundant coverage between AP's
in the 5 GHz band, it's unlikely that the ratio of students per AP will even
come into play except in your more public/general spaces e.g. living room.
In our newer residential halls, our design results in there
