Generic Call Flow
Accounting Stop (Session End)
In Flow 9c, the client sends an Accounting-Stop to the Cisco AR 3.5 server to end the session. The
Accounting-Stop message includes an updated quota array with the usage adjustments since the previous
authorization in the VSA form.
Table 6-9 lists the attributes included in the Accounting-Stop message set to the Cisco AR 3.5 server and
forwarded to the billing server.
Accounting Response (Final Status)
In Flow 9s, the Cisco AR 3.5 server sends the used quota array to the billing server in an
Accounting-Stop message. Any values returned by the billing server in Flow 10b are discarded.
Flow 10s shows the Cisco AR 3.5 server sending final Accounting-Response message to the AAA client.
