    Supported Attributes in Access-Accept Messages

    The following tables indicate how the MobileNext Broadband Gateway processes RADIUS attributes or 3GPP and Juniper Networks VSAs received in RADIUS Access-Accept messages. If authentication is successful, the RADIUS server sends an Access-Accept message that provides specific configuration information necessary to begin delivery of service to the user.

    RADIUS IETF Attributes Supported in Access-Accept Messages

    Table 1 lists the RADIUS attributes supported by the broadband gateway in Access-Accept messages.
