RADIUS Accounting
Using an external RADIUS server, the AP can track and record the length
of client sessions on the access point by sending RADIUS accounting
messages per RFC2866. When a wireless client is successfully
authenticated, RADIUS accounting is initiated by sending an “Accounting
Start” request to the RADIUS server. When the wireless client session
ends, an “Accounting Stop” request is sent to the RADIUS server.
Session Length
Accounting sessions continue when a client reauthenticates to the same
AP. Sessions are terminated when:
• A client disassociates.
• A client does not transmit any data to the AP for a fixed amount of
time.
• A client is detected on a different interface.
If the client roams from one AP to another, one session is terminated and
a new session is begun.
NOTE:
This feature requires RADIUS authentication using MAC Access
Control or 802.1x. Wireless clients configured in the Access Point’s
static MAC Access Control list are not tracked.
