Configuring ISG Accounting
Information About ISG Accounting
3
Accounting Records
ISG accounting uses the RADIUS protocol to facilitate interaction between ISG and an external
RADIUS-based AAA or mediation server. ISG sends accounting records with the associated attributes
to the AAA accounting method list when the following events occur: account logon, account logoff,
service logon, and service logoff. The accounting server can be configured to interpret the records to
generate bills for postpaid sessions.
Account Logon and Logoff
ISG sends a RADIUS Accounting-Request record to the specified AAA method list when a subscriber
logs onto or off of ISG. The Acct-Status-Type attribute included in the Accounting-Request record
indicates if the record marks the start (commencement) of the subscriber session or the stop
(termination) of the session.
When the aaa accounting command is enabled with the system, default, start-stop, and group
keywords, accounting records are sent to the AAA server. When a subscriber logs on, ISG sends an
Accounting-Start record to the AAA server. When a subscriber logs off, ISG sends an Accounting-Stop
record.
Service Logon and Logoff
ISG sends a RADIUS Accounting-Start record to the AAA server when a service is activated for a
subscriber, and it sends an Accounting-Stop record when a service is deactivated. The record contains a
different accounting session ID from the accounting session ID of the parent session.
The Acct-Status-Type attribute included in the Accounting-Request record indicates whether the record
marks the start or the end of the service. The name of the service is included in accounting records for
service logon and logoff.
Accounting records may be sent for events other than account and service logon and logoff. See the
“Configuring Accounting” chapter of the Cisco IOS XE Security Configuration Guide, for more
information.
Interim Accounting Updates
ISG supports interim (intermittent) RADIUS accounting updates, which work the same way as
“watchdog” RADIUS accounting. Accounting updates are sent between the times that ISG sends
Accounting-Start and Accounting-Stop records.
ISG supports two types of interim accounting: accounting updates for new information (such as a new
IP address) and periodic accounting, in which accounting records are sent at a configurable interval.
Interim accounting for new information can be enabled or disabled globally. Periodic accounting can be
enabled for specific contexts, such as globally, in user profiles, and in services.
Broadcast Accounting
ISG supports AAA broadcast accounting, which is the ability to send user accounting records to multiple
RADIUS servers. AAA broadcast accounting provides service providers with geographical redundancy
for RADIUS servers, and provides accounting records to partners in wholesale models. For information
about configuring AAA broadcast accounting, see the “Configuring Accounting” chapter in the
“Authentication, Authorization, and Accounting” part of the Cisco IOS XE Security Configuration
Guide.
