The RADIUS server and an AP exchange status information, such as the start, end, or update of client sessions at the AP. These data packets are characterized by the behavior of the logged-on clients.
With the status types "Accounting-On" and "Accounting-Off", the AP informs the RADIUS server about its general ability to perform RADIUS accounting:
- Accounting-On
- When the device switches to an operating state where it can exchange accounting information with a RADIUS server, it sends an "Accounting-On".
- Accounting-Off
- When the device switches to an operating state where it cannot exchange accounting information with a RADIUS server, it sends an "Accounting-Off".
The following conditions trigger the transmission of an "Accounting-On" or "Accounting-Off":
- The device activates or deactivates a physical WLAN interface with the appropriate SSID. Note: Deactivation can also be the result of overheating, loss of connection or incorrect link detection.
- The WLAN interface switches into a non-AP mode (i.e. neither managed nor stand-alone-AP) or back.
- In P2P mode, the device switches into "exclusive" mode, which disables all SSIDs.
- The device activates or deactivates an SSID.
- The device activates or deactivates the RADIUS accounting for an SSID.
