Overview 27
2 The Attribute field contains special authentication, authorization, and accounting
information that provides the configuration details of a request or response. This
field is represented by the triplet of Type and Length and Value. The following
table lists the major standard attribute values defined by RFC:
3 Access-Reject
The packet is transmitted by the server to the client. If any
attribute value carried in the Access-Request is unacceptable,
the server rejects the user and sends back an Access-Reject
response.
4 Accounting-Request
The packet carries user information and is transmitted by the
client to the server to request the server to start accounting.
The server can determine whether to start accounting
according to the field of the Acct-Status-Type attribute. The
attributes carried in this type of packet are basically the same
as those carried by an Access-Request packet.
5 Accounting-Response
The packet is transmitted by the server to the client, notifying
that the server has received the Accounting-Request and has
correctly record the accounting information. The packet
carries such information as input/output bytes and packets,
and session duration.
