June 30, 2006 Appendix A: SG-1 Vendor-Specific Attributes
SG1-UM-8500-03 A-7
Scenario Examples:
•enable – Enables the sending of the accounting information.
•lastpacket – This accounting operation mode enables last packet accounting session time, which is based on
the last user's packet timestamps. The last packet accounting calculating method is operated in all session
disconnections (such as, "clear user", idle timeout, echo, etc.). Note that this accounting method is relevant for
accounting stop and accounting off RADIUS messages.
•enable-on-ip-update – This accounting operation mode enables the session accounting on session IP
address updating regardless of the current accounting status.
•interim-update – Enables the sending of the interim update accounting information for a connected session.
In this accounting type, the system sends an accounting message with Acct-Status-Type value 3 (Interim-
Update) that includes the same attributes as being sent in accounting stop and off messages, except for the
termination cause. The accounting information is being sent every time period that was configured in the
received accounting attribute. The accounting:interim-update attribute is operated in hierarchy mode and sup-
ports both user and service levels. When received in service authentication it operates only in the service life-
time and sends the service accounting update. When received in user authentication it operates during the
whole session lifetime and sends the session accounting update.
•General:
Scenario Action RADIUS definition Accounting Behavior
1 A user is connecting
to the network User definition in the
RADIUS includes the
user:accounting=disable
sub-attribute.
No accounting information
is sent (Start and Stop).
A service is selected
by the user Service definition in the
RADIUS includes the
user:accounting=enable
sub-attribute.
Only accounting on and off
for the selected service
are sent.
3 A user is connecting
to the network User definition in the
RADIUS does not include the
user:accounting=disable
sub-attribute.
Accounting Start and Stop
are sent.
A service is selected
by the user Service definition in the
RADIUS does not include the
user:accounting sub-attribute.
No accounting on and off
are sent.
A service is selected
by the user Service definition in the
RADIUS includes the
