5) The Authenticator field (16 bytes) is used to authenticate the response from the RADIUS server;
and is used in the password hiding algorithm. There are two kinds of authenticators: Request
Authenticator and Response Authenticator.
6) The Attributes field contains specific authentication/authorization/accounting information to provide
the configuration details of a request or response message. This field contains a list of field triplet
(Type, Length and Value):
z
The Type field (one byte) specifies the type of an attribute. Its value ranges from 1 to 255. Table
26-2 lists the attributes that are commonly used in RADIUS authentication/authorization.
z
The Length field (one byte) specifies the total length of the attribute in bytes (including the Type,
Length and Value fields).
z
The Value field (up to 253 bytes) contains the information of the attribute. Its format is determined
by the Type and Length fields.

The RADIUS protocol has good scalability. Attribute 26 (Vender-Specific) defined in this protocol allows
a device vendor to extend RADIUS to implement functions that are not defined in standard RADIUS.
