Configuring Subscriber Profiles for L2TP Support
This section provides information and instructions on the following procedures:
RADIUS and Subscriber Profile Attributes Used
Configuring Local Subscriber Profiles for L2TP Support

Verifying the L2TP Configuration
Important:
Since the instructions for configuring subscribers differ between RADIUS server applications, this
section only provides the individual attributes that can be added to the subscriber profile. Refer to the documentation
that shipped with your RADIUS server for instructions on configuring subscribers.
RADIUS and Subscriber Profile Attributes Used
Attribute-based L2TP tunneling is supported through the use of attributes configured in subscriber profiles stored either
locally on the system or remotely on a RADIUS server. The following table describes the attributes used in support of
LAC services. These attributes are contained in the standard and VSA dictionaries.
