Configuring Service Interim Accounting

654
To support RADIUS accounting for Service Manager, the RADIUS Acct-Session-ID attribute
[44] has been extended to include a colon-separated identifier, which uniquely identifies
a service for a subscriber. For example:
erx FastEthernet 12/0:0001048580:002478
The Service-Session attribute (VSA 26-83) identifies the name of the service. This
attribute is the value of the Activate-Service or Deactivate-Service attribute (including
parameter values) that was used in the RADIUS Access-Accept message to activate or
deactivate the service session. For example:
tiered(1280000, 5120000)
Table 147 on page 654 lists the RADIUS accounting attributes used by the Service Manager
application.

Interim accounting determines how often accounting information is updated and sent
to an accounting server. In addition to the user-based interim accounting supported on
the router, Service Manager supports service-related interim accounting—you can
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.
