Garrett, we run with 15 minute lease times on the wireless network, the only minor issue we came across was the default ARP table timeout was 30 minutes, which would normally be fine, so we needed to lower that on the network switches to match. Many Thanks Peter

From: The EDUCAUSE Wireless Issues Constituent Group Listserv [mailto:[email protected]] On Behalf Of Garrett Harmon Sent: Wednesday, September 30, 2009 11:09 AM To: [email protected] Subject: [WIRELESS-LAN] wireless DHCP lease time We're running into some issues at the ramp up of a quarter with our DHCP lease time attempting to utilize the /24's we currently pool for our main essid. We moved from 1hr. to 30 minutes, but are still running out of leases occasionally. For instance, we have 160 users in a /24, but due to the transient nature of wireless/classes leases that are used for a brief moment the cycle isn't quite efficient enough. What is everyone else using for wireless DHCP lease times? I know I can just add another /24 to the pool, but the networks are not being utilized enough. We want to try 15 minutes but are wondering if we will start to run into issues related with that? Your input is greatly appreciated!!
