Steve,
We here at Liberty University tend to run 1 day lease times on our
wireless network.
Previous to our move to Aruba, we used /20s with fat
. Since our controllers can handle 512 APs pr
controller, we are currently running 16 /23 subnets in each pool.

Not sure if this is the case for anyone, but one of the issues we
ran into with lease shortages was related to maybe on oversight on our
part. The ISC dhcp has a max-lease-time and a default-lease-time
value. While wireless was set to hand out 30-minute leases (default-

This morning we noticed that our pools (Aruba VLAN pools, 32* /24)

We run 4 /23's (one per class) with 4 day lease
times. It's very tight right now for freshmen and sophomore's but lots
of room for juniors and seniors. Each class is about 350-450
students. I'm looking to add another /23 per class to provide some
head room. We run 4 day lease times for the

We run 30 minute leases for most of SSIDs, no problems. We saw an
unexpected boost in wireless usage this semester though, and had to go
from /22 networks to /20 to accommodate the new users and leave room for

We use a pool of 8000 addresses for a peak usage of 5000 users at a time
(and we're already needing to expand the available address pool), we
also use NAT to avoid wasting too many public addresses. The only issue
