Configuring RADIUS Accounting

The TCA 8000 and TCA 8500 Timing Servers support RADIUS accounting for the user logged in to the Timing Server. Once the user is logged in to the Timing Server, the Timing Server passes the accounting information to the configured RADIUS accounting servers. The Timing Server stops the accounting process when the user session is closed either voluntarily or involuntarily. The Timing Server waits for acknowledgment from the accounting servers for each accounting packet.

When the RADIUS accounting is enabled, the Timing Server tries to log the accounting information in any one of the configured RADIUS accounting server based on the configured timeout period and number of retries. When the logging of accounting information fails for all configured accounting server, the Timing Server raises an ACCOUNTING_SERVER_UNAVAILABLE alarm.

When the RADIUS accounting server is unavailable, the accounting information (latest 15 commands) is buffered. The Timing Server sends the buffered information to the RADIUS accounting server after the server becomes available.

The accounting process supports login accounting, interactive commands accounting, and configuration commands accounting.

Note:

  • The selection of RADIUS accounting server to log the accounting information is based on the order in the RADIUS accounting server list.
  • The accounting process is implemented only for the Accounting Request and Accounting Response messages.
  • The RADIUS accounting is not supported for shell users.
  • The accounting process does not support immediate accounting and accounting of web configurations.

The usage of RADIUS accounting servers provides the following advantages:
