2) The Identifier field (one byte) identifies the request and response packets. It is
subject to the Attribute field and varies with the received valid responses, but
keeps unchanged during retransmission.
3) The Length field (two bytes) specifies the total length of the packet (including the
Code, Identifier, Length, Authenticator and Attribute fields). The bytes beyond the
length will be regarded as padding bytes and are ignored upon receiving the
packet. If the received packet is shorter than the value of this field, it will be
discarded.
4) The Authenticator field (16 bytes) is used to verify the packet returned from the
RADIUS server; it is also used in the password hiding algorithm. There are two
kinds of authenticators: Request and Response.
5) The Attribute field contains special authentication, authorization, and accounting
information to provide the configuration details of a request or response packet.
This field is represented by a field triplet (Type, Length and Value):
The Type field (one byte) specifies the type of the attribute. Its value ranges from 1
to 255. Table 1-2 lists the attributes that are commonly used in RADIUS
authentication and authorization.
The Length field (one byte) specifies the total length of the Attribute field in bytes
(including the Type, Length and Value fields).
The Value field (up to 253 bytes) contains the information about the attribute. Its
content and format are determined by the Type and Length fields.
