Hi Everyone,

I am not much aware of how the cloud based captive portal solutions work. I wanted to understand how a cloud hosted captive portal can be used to enable/disable MAC based authentication of Wi-Fi users? Consider following use-case:

  1.  A new Wi-Fi user selects an Open SSID (with MAC based authentication) and because she is not yet registered (MAC auth fails) and she gets re-directed to a cloud based Captive portal.
  2.  She subscribers herself using this captive portal and once the subscription is done, the captive portal somehow enables her MAC address in AAA for MAC based authentication.

I have following queries here:

  1.  How does a cloud based captive portal comes to know about the MAC address of end user device to provision MAC address in AAA server?
  2.  What configuration changes are usually required at Wi-Fi operators end e.g. WLC for accessing cloud based captive portals?
