I am using Cloud WiFi. A network is configured with captive portal login. In advanced settings it is set to allow the user to stay connected for 15 minutes. When checking the session inventory under analytics, there are session in excess of 15 minutes. Seeking clarification on why this is happening and a possible explanation of how the sessions are generate. For example, if a user who is connected to one AP roams to another AP, is a second session created?
