4.2.14 Configuring 802.1x
Accounting
Our 802.1x has implemented the accounting function. Accounting is based on interval. In other
words, the 802.1x records the length of the period between the first successful authentication
of the user and the user’s logoff or when the switch detects user disconnection.
After the first successful user authentication, the switch sends an accounting start request to
the server. When the user gets off-line or the switch finds that the user has got off line or when
the physical connection of the user is broken, the switch sends an accounting end request to
the server. The server group records this information in the database of the server group.
Based on such information, the NMS can provide the basis for accounting.
Our 802.1x stresses the reliability of accounting, and it specially supports the backup
accounting server to avoid failures of the accounting server. When a server can no longer
provide the accounting service due to various reasons, the switch will automatically forward
the accounting information to another backup server. This greatly improves the reliability of
accounting.
When a user exits by itself, the accounting duration is accurate. When the connection of the
user is broken by accident, the accounting accuracy depends on the re-authentication interval
(the switch detects the disconnection of a user by using the re-authentication mechanism).
To enable the accounting function of the device, the following settings are necessary on the
device:
