RADIUS accounting
RADIUS accounting works as follows.
1. One of the following events occur on the BigIron RX:
• A user logs into the management interface using Telnet or SSH
• A user enters a command for which accounting has been configured
• A system event occurs, such as a reboot or reloading of the configuration file
2. The BigIron RX checks its configuration to see if the event is one for which RADIUS accounting
is required.
3. If the event requires RADIUS accounting, the BigIron RX sends a RADIUS Accounting Start
packet to the RADIUS accounting server, containing information about the event.
4. The RADIUS accounting server acknowledges the Accounting Start packet.
5. The RADIUS accounting server records information about the event.
6. When the event is concluded, the BigIron RX sends an Accounting Stop packet to the RADIUS
accounting server.
7. The RADIUS accounting server acknowledges the Accounting Stop packet.
