Simple IP Unclassified MAC Authentication (MAC TAL and Web
Login) Call Flows
The MAC Transparent Auto Login (TAL) authentication method is associated with the web authentication
method and is prevalent in public access control as used in public wireless LAN (PWLAN) applications or
in limited usage as in broadband residential access. Here, many sessions are aggregated on a single VLAN
or interface at the broadband remote access server (BRAS), and individual sessions are identified based on
the source MAC address for the Layer 2 access subscriber.
MAC TAL enables the iWAG to authorize a subscriber on the basis of the subscriber's source MAC address.
After authentication, the iWAG applies the auto-login services on the session and the subscriber will be able
to access the service. If the initial authorization based on the MAC address fails, then the iWAG subscriber
is redirected to the ISP's web portal, where the subscriber enters the ISP-assigned credentials (username and
password) to complete the authentication in order to avail the ISP's services. The iWAG then applies the
services that the subscriber selected from the portal, and provides the subscriber full access to those services.
This use case covers the following:
• iWAG session creation
