RADIUS Attributes in Preauthentication Request

Table 6 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 6: 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.

For more information about these attributes, see RADIUS IETF Attributes.
