Accounting Example

Back once again to our sample network, you can now use AAA accounting to perform one of the previously mentioned types of accounting. In this example, you pick up after authentication and authorization have taken place. Here resource accounting performs start stop accounting for FTP on the network. See Figure 1-3.

Figure 1-3. Basic Accounting of Resources

In this example, the following process is performed. Note that once again authentication must take place.

Step 1.	When a user has been authenticated, the AAA accounting process generates a start message to begin the accounting process.
Step 2.	When the user finishes, a stop message is recorded ending the accounting process.

Once again, a method list determines what type of accounting is to be performed.
