HP 12500 Series Configuration Manual page 19

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:
The Type filed (1 byte long) indicates the type of the attribute. It is in the range of 1 to 255.
•
2 lists the commonly used attributes for RADIUS authentication, authorization and accounting,
which are defined in RFC 2865, RFC 2866, RFC 2867, and RFC 2868. For more information about
these attributes, see
The Length field (1 byte long) indicates the length of the attribute in bytes, including the Type, Length,
•
and Value fields.
The Value field (up to 253 bytes) indicates the value of the attribute. Its format and content depend
•
on the Type and Length fields.
