    RADIUS Attributes in Preauthentication Request

    Table 1 describes the RADIUS IETF attributes that are always included in a preauthentication request to obtain the LLID. The attributes are listed in ascending order by standard number.

    Table 1: RADIUS IETF Attributes in Preauthentication Request

    Attribute Number

    Attribute Name

    Description

    [1]

    User-Name

    Name of the user associated with the LLID, in the format:

    NAS-Port:<NAS-IP-Address>:<Nas-Port-Id>

    For example, nas-port:172.28.30.117:atm 4/1.104:2.104

    [2]

    User-Password

    Password of the user to be authenticated; always set to “ juniper”

    [4]

    NAS-IP-Address

    IP address of the network access server (NAS) that is requesting authentication of the user; for example, 172.28.30.117

    [5]

    NAS-Port

    Physical port number of the NAS that is authenticating the user; this is always interpreted as a bit field

    [6]

    Service-Type

    Type of service the user has requested or the type of service to be provided; for example, framed

    [61]

    NAS-Port-Type

    Type of physical port the NAS is using to authenticate the user

    [77]

    Connect-Info

    Actual user name; for example, jdoe@xyzcorp.east.com

    [87]

    NAS-Port-Id

    Text string that identifies the physical interface of the NAS that is authenticating the user; for example, atm 4/1.104:2.104

    The use of radius commands such as radius calling-station-format or radius override calling-station-id to control or change the inclusion of these attributes in the preauthentication request has no effect.
