The Length field (2 bytes long) indicates the length of the entire packet, including the Code,
•
Identifier, Length, Authenticator, and Attribute fields. Bytes beyond this length are considered
padding and are neglected upon reception. If the length of a received packet is less than this length,
the packet is dropped. The value of this field is in the range 20 to 4096.
• The Authenticator field (16 bytes long) is used to authenticate replies from the RADIUS server and to
encrypt user passwords. There are two types of authenticators: request authenticator and response
authenticator.
The Attributes field, variable in length, carries the specific authentication, authorization, and
•
accounting information that defines the configuration details of the request or response. This field
may contain multiple attributes, each with three sub-fields:
Type—(1 byte long) Type of the attribute. It is in the range 1 to 255. Commonly used attributes
for RADIUS authentication, authorization and accounting are listed in
Length—(1 byte long) Length of the attribute in bytes, including the Type, Length, and Value
