RADIUS Accounting Statistics for Subscriber Access Overview
The AAA Service Framework enables you to configure how the router collects and uses accounting statistics for subscriber management.
For example, you can specify when statistics collection is terminated, the order in which different accounting methods are used, the types of statistics collected, and how often statistics are collected. You can also configure the router to request that the RADIUS server immediately update the accounting statistics when certain events occur, such as when a subscriber logs in or when a change of authorization (CoA) occurs.
Subscriber management provides two levels of subscriber accounting—subscriber session and service session. In subscriber session accounting, the router collects statistics for the entire subscriber session. In service session accounting, the router collects statistics for specific service sessions for the subscriber.
 | Note: Subscriber management counts forwarded packets only. Dropped traffic (for example, as a result of a filter action) and control traffic are not included in the accounting statistics. |
The router uses the RADIUS attributes and Juniper Networks VSAs listed in Table 1 to provide the accounting statistics for subscriber and service sessions. If the session has both IPv4 and IPv6 families enabled, the router reports statistics for both families.
| RADIUS reports subscriber statistics as an aggregate of both IPv4 statistics and IPv6 statistics.
