Figure 1-15 Configure the AAA accounting method for the ISP domain Perform the following configurations, as shown in Figure 1-15. z Select the domain name test. z Select the Accounting Optional checkbox and then select Enable. z Select the Default Accounting checkbox and then select RADIUS as the accounting mode. z Select system from the Name drop-down list to use it as the accounting scheme. z Click Apply. A configuration progress dialog box appears. z After the configuration process is complete, click Close. Configuration Guidelines When configuring the RADIUS client, note that: 1) When you modify the parameters of the RADIUS scheme, the system does not check whether the scheme is being used by users. 2) After accounting starts, update-accounting and stop-accounting packets will be sent to the designated server, and no primary/secondary server switchover will take place even if the designated server fails. Such a switchover can take place only during AAA session establishment. 3) If an AAA server has active TCP connections, it cannot be removed. 4) RADIUS does not support accounting for FTP users. 5) If the iMC server is used as the RADIUS server, it is necessary to configure accounting as optional for users in the ISP domain because the iMC server does not respond to accounting packets. 1-16
