Hey, there is no way to set an expirey time on a Guest account. You would need a 3rd party db such as Clearpass for this. You can however set a Inactivity timeout (Under the SSID wizard ) Specify an interval for session timeout in seconds, minutes or hours. If a client session is inactive for the specified duration, the session expires and the users are required to log in again. You can specify a value within the range of 60-86400 seconds or up to 24 hours for a client session. The default value is 1000 seconds.
