Using the AAA Logical Line Identifier to Track Subscribers

You can configure the router to support the AAA logical line identification feature.
This feature enables service providers to track subscribers on the basis of a virtual
port known as the logical line ID (LLID).
The LLID is an alphanumeric string that logically identifies a subscriber line. The
service provider maps each subscriber to an LLID based on the user name and circuit
ID from which the customer's calls originate. When a subscriber moves to a new
physical line, the service provider's customer profile database is updated to map to
the same LLID.
Because a subscriber's LLID remains the same regardless of the subscriber's physical
location, using the LLID gives service providers a more secure mechanism for tracking
subscribers and maintaining the customer database.

How the Router Obtains and Uses the LLID

To obtain an LLID for a subscriber, the router must issue two RADIUS access requests:
a preauthentication request to obtain the LLID, followed by an authentication request
encoded with the LLID returned in response to the preauthentication request.
To configure this feature, you:
