RFC 2866 RADIUS Accounting June 2000
5.4. Acct-Output-Octets
Description
This attribute indicates how many octets have been sent to the
port in the course of delivering this service, and can only be
present in Accounting-Request records where the Acct-Status-Type
is set to Stop.
A summary of the Acct-Output-Octets attribute format is shown below.
The fields are transmitted from left to right.

Length

Value
The Value field is four octets.
5.5. Acct-Session-Id
Description
This attribute is a unique Accounting ID to make it easy to match
start and stop records in a log file. The start and stop records
for a given session MUST have the same Acct-Session-Id. An
Accounting-Request packet MUST have an Acct-Session-Id. An
Access-Request packet MAY have an Acct-Session-Id; if it does,
then the NAS MUST use the same Acct-Session-Id in the Accounting-
Request packets for that session.
The Acct-Session-Id SHOULD contain UTF-8 encoded 10646 [7]
characters.
Rigney Informational [Page 15]
RFC 2866 RADIUS Accounting June 2000
For example, one implementation uses a string with an 8-digit
upper case hexadecimal number, the first two digits increment on
each reboot (wrapping every 256 reboots) and the next 6 digits
counting from 0 for the first person logging in after a reboot up
to 2^24-1, about 16 million. Other encodings are possible.
A summary of the Acct-Session-Id attribute format is shown below.
The fields are transmitted from left to right.

The String field SHOULD be a string of UTF-8 encoded 10646 [7]
characters.
5.6. Acct-Authentic
Description
This attribute MAY be included in an Accounting-Request to
indicate how the user was authenticated, whether by RADIUS, the
NAS itself, or another remote authentication protocol. Users who
are delivered service without being authenticated SHOULD NOT
generate Accounting records.
A summary of the Acct-Authentic attribute format is shown below. The
fields are transmitted from left to right.

5.8. Acct-Input-Packets
Description
This attribute indicates how many packets have been received from
the port over the course of this service being provided to a
Framed User, and can only be present in Accounting-Request records
where the Acct-Status-Type is set to Stop.

Type
49 for Acct-Terminate-Cause
Length
6
Value
The Value field is four octets, containing an integer specifying
the cause of session termination, as follows:
1 User Request
2 Lost Carrier
3 Lost Service
4 Idle Timeout
5 Session Timeout
6 Admin Reset
7 Admin Reboot
8 Port Error
9 NAS Error
10 NAS Request
11 NAS Reboot
12 Port Unneeded
13 Port Preempted
14 Port Suspended
15 Service Unavailable
16 Callback
17 User Error
18 Host Request
The termination causes are as follows:
User Request User requested termination of service, for
example with LCP Terminate or by logging out.
Lost Carrier DCD was dropped on the port.
Lost Service Service can no longer be provided; for
example, user's connection to a host was
interrupted.
Idle Timeout Idle timer expired.
Session Timeout Maximum session length timer expired.
Admin Reset Administrator reset the port or session.
Rigney Informational [Page 20]
RFC 2866 RADIUS Accounting June 2000
Admin Reboot Administrator is ending service on the NAS,
for example prior to rebooting the NAS.
Port Error NAS detected an error on the port which
required ending the session.
NAS Error NAS detected some error (other than on the
port) which required ending the session.
NAS Request NAS ended session for a non-error reason not
otherwise listed here.
NAS Reboot The NAS ended the session in order to reboot
non-administratively ("crash").
Port Unneeded NAS ended session because resource usage fell
below low-water mark (for example, if a
bandwidth-on-demand algorithm decided that
the port was no longer needed).
Port Preempted NAS ended session in order to allocate the
port to a higher priority use.
Port Suspended NAS ended session to suspend a virtual
session.
Service Unavailable NAS was unable to provide requested service.
Callback NAS is terminating current session in order
to perform callback for a new session.
User Error Input from user is in error, causing
termination of session.
Host Request Login Host terminated session normally.
5.11. Acct-Multi-Session-Id
Description
This attribute is a unique Accounting ID to make it easy to link
together multiple related sessions in a log file. Each session
linked together would have a unique Acct-Session-Id but the same
Acct-Multi-Session-Id. It is strongly recommended that the Acct-
Multi-Session-Id contain UTF-8 encoded 10646 [7] characters.
A summary of the Acct-Session-Id attribute format is shown below.
The fields are transmitted from left to right.
