An application profile can be provided using RADIUS to be used during portal authentication. The WLAN-GW ISA redirects all traffic to a linked AA ISA, where all AA functionalities can be used to enable a more extensive portal redirect. The WLAN-GW redirect and filter are completely bypassed, but the UE is kept in a portal authentication state. The UE can subsequently be promoted to DSM or ESM with a CoA as with regular portal functionality. When promoting to DSM, AA is disabled unless a DSM application profile is provisioned using configuration or RADIUS.
See Application Assurance support for more information about enabling AA functionality for a WLAN-GW.
