configure an interim accounting interval for services that are created during a user
RADIUS-based login and services that are activated by a CoA operation.
The service interim accounting interval is specified by the RADIUS
Service-Interim-Acct-Interval attribute (VSA 26-140) that is included in the RADIUS
Access-Accept message or CoA-Request message that activates a service session.
Because the Service-Interim-Acct-Interval attribute is a tagged attribute, you can configure
different interim accounting intervals for a particular user's various services.
You can use the aaa service accounting interval command to specify the default service
interim accounting interval. Service Manager uses this interval value for service accounting
when the Service-Interim-Acct-Interval attribute is not configured.
NOTE: You can also configure interim accounting for users. A user interim
accounting interval is configured in the Acct-Interim-Interval RADIUS attribute
(RADIUS attribute 85). You use the aaa user accounting interval command
to specify the default user interim accounting interval, which is used when
RADIUS attribute 85 is not configured. See "Configuring Remote Access" on
page 3 for information about configuring user interim accounting.
When the Service-Interim-Acct-Interval attribute is configured for a service, Service
Manager uses the guidelines shown in Table 148 on page 665 to determine the correct
interim accounting interval to use for the service.

Service-Interim-Acct-
Interval Value
0
1–599
600–86400
86401 or greater
The tag for the service-interim-acct-
interval attribute does not match the
tag for any service-activate attribute
(VSA 26-65)
Table 149 on page 666 describes a sample Acct-Start message for a service session. In
the table, the three fields used by Service Manager are shown in bold characters. An
Acct-Start message for a subscriber session without any active services does not include
the Service-Session attribute.
