Hi Curtis, I have 8k users daily, what I did is have an interface group with multiple /20 subnets "I have broadcast forwarding disabled so it shouldn't matter", and I use AAA override to send the interface group back when authentication is done. On the WLC side, it uses round robin for selecting the interface inside the interface group.
Lease time I use is 8 hours which are the work time. Yahya Jaber.

Larsen Sent: Tuesday, May 8, 2018 02:17 To: [email protected] Subject: [WIRELESS-LAN] DHCP Lease Times Hello, I'm curious to see what process/algorithm others use when determining DHCP lease times for your Wi-Fi networks. Assuming plenty of IP addresses, what DHCP lease time is ideal to assign to clients in a WLAN with 90,000 unique clients/day, where avg. user spends 3hrs connected , but some (maybe 20%) go several days, Keep in mind that 90% are the same user/device every day. What level of DHCP pool utilization do you think is best? Have you found any industry documentation on this? Thanks in advance. -Curtis ********** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/discuss. ________________________________ This message and its contents including attachments are intended solely for the original recipient.
