https://community.extremenetworks.com/t5/extremecloud-iq-controller/maintain-client-sessions-in-event-of-poll-failure/m-p/73107#M142 When our E1120 controller is offline the APs configured on it stop working. I found that the Poll Timeout setting found in the Device Group and individual AP settings&nbsp; can be set&nbsp; as high as 600 seconds.&nbsp; That helps, a bit.<BR /><BR />In our old controller (A C35 running 10.x software) there is an option under the AP Advanced settings named&nbsp; "Maintain client sessions in event of poll failure". It would prevent the APs from failing no matter how long the controller was down.&nbsp; Is the same behavior available on our E1120 controller?
