What is Radius Accounting?
The Accounting feature of the RADIUS protocol can be used independently of RADIUS authentication or authorization.
The RADIUS accounting process begins when the user is granted access through the RADIUS server. Once access has been granted, the Network Access Server (NAS) sends a RADIUS Accounting Request packet, which signifies that the user’s access to the network has begun, to the RADIUS server. This packet normally contains the user’s ID, point of access, and network address, as well as a unique session identifier. This process is called an Accounting Start.
The AP sends an Accounting Request packet to get the Interim update, which consists of session duration and current data usage. This packet updates the status of the user’s session to the RADIUS server.
Accounting-Stops once the Client Connection is terminated.
Below are the Radius Accounting captures taken on the Radius Server.
