I would like to set the time limit of how often a guest user needs to reauthenticate via captive portal. For instance, a device should not have to reauthenticate via captive portal more than once in a 24 hour period. I see many different possible settings and I'm confused on what each one controls.
In ClearPass Enforcement Policies:
1. RADIUS - Session-Timeout
2. Session-Check - Allowed-Duration
3. Endpoint - MAC_Auth_Expiry (Now Plus X hrs)
On Wireless Controller:
1. aaa policy - user-idle-timeout
What is the difference between all of these settings and which ones are actually required to accomplish what I want?
I heard that there is a 12 hour max for this setting for captive portals, is this true?
