# Subscriber AAA Accounting Messages Overview

Accounting messages identify service provisions and use on a per-user or per-tunnel basis. These messages keep track of when a particular service is initiated and terminated for a specific user.

JunosE Software supports the Acct-On message on startup or configuration of the first accounting server. Acct-Off messages are supported when the last RADIUS accounting server in a virtual router is removed, when the router is shut down, and when a virtual router that has configured RADIUS accounting servers is deleted.

Beginning with JunosE Release 11.0.0, you can configure the router to send the Partition-Accounting-On and Partition-Accounting-On messages to the RADIUS server whenever an ICR partition toggles between the backup and master states.

The router supports the following types of accounting messages:

- Acct-Start
- Acct-Stop
- Interim-Acct
- Acct-On
- Acct-Off
- Partition-Accounting-On
- Partition-Accounting-Off
