Guest access clients that have had successful web authentication are allowed to sleep and wake up without having to go through another authentication process. You can configure the duration for which the sleeping clients are to be remembered for reauthentication. The valid range is 1 hour to 720 hours (30 days), with the default duration being 12 hours. You can configure the duration on a WLAN and on a user group policy that is mapped to the WLAN.
Re: Re:Anchor-Foreign setup with webauth , clients prompted for
Sleeping clients work after the idle timer expires. You need to make sure that your configuration is correct. The session timer should always be higher than the idle timer. These have to be set on the anchor WLC. Idle timer I wouldn't go past 2-4 hours and only use sleeping clients if you don't want users to login after x number of hours (after idle timer expires) up to 30 days.
If clients still are being forced to login, then there is a configuration issue.
