Reduce re-auths during wireless client roaming

Josh Morris — Mon, 11 Mar 2019 06:57:36 GMT

I am using ISE (1.4 patch 😎 to auth clients on my wireless guest network. Most are done via web portal with a registered device group. I am getting a lot of CoA failures and Radius drops. The cause seems to be from roaming clients. I have four WISMs. All my WAPs are located on a WISM based on their building. So all WAPs in a particular building are on the same WISM. But people walking around campus still transfer to different controllers, which causes a bunch of re-auths (and CoA failures) in ISE. Screenshot attached.

I'm trying to find a way to stop this behavior. Any help is appreciated.

Also, could someone tell or show me what a live log SHOULD look like when there are roaming clients?
