    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




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


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



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



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



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



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



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



    Actual user name; for example,



    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.
