I am using a Cisco WLC 9800 L running 17.9.3. I am attempting to set up LWA. Everything is working well in the tests I have conducted, except for the WLC is failing to remember the MAC addresses of sleeping clients. As soon as a client disconnects from the network and reconnects, they are asked to login again. I have sleeping client status turned on and set to the max value of 43200 minutes. Is there anything that can cause this to happen?
