This chapter provides examples of how to configure and manage RADIUS on AsterNOS devices using NETCONF.

RADIUS Vendor Attributes

For supporting RADIUS authorization with vendor-specific attributes, AsterNOS provides a set of predefined vendor attributes.

The following table lists the supported vendor attributes:

VENDOR        Asterfusion  56928
BEGIN-VENDOR  Asterfusion
ATTRIBUTE     ASTER-Terminal-Type 1 string
ATTRIBUTE     ASTER-Terminal-Vendor 2 string
ATTRIBUTE     ASTER-Privilege 3 integer
ATTRIBUTE     ASTER-Service 4 string
ATTRIBUTE     ASTER-Command 5 string
ATTRIBUTE     ASTER-Argument 6 string
ATTRIBUTE     ASTER-Error 7 string
END-VENDOR    Asterfusion

If user want to assign vendor attributes to a user, please configure corresponding attributes on radius server.

ASTER-Privilege is used to assign privilege level to a user. The value range is from 0 to 15, where 0 is the lowest privilege level and 15 is the highest privilege level.
ASTER-Service is used to assign service level command permission to a user. The value will be provided by other documents.
ASTER-Command is used to assign cmd level command permission to a user.

Example of configuring vendor attributes on freeradius server users file:

bob0   Cleartext-Password := "hello"
    Service-Type = NAS-Prompt-User,
    ASTER-Privilege = 0,
    ASTER-Service = "interface,l2",
    ASTER-Command = "(configure|exit|(^interface.*))"
