SYMPTOMS

When using a U.S. Robotics(USR)/3Com Total Control Chassis with Microsoft Internet Authentication Service (Radius), administrators may notice that the Radius log files do not show up properly.

CAUSE

There are several reasons why this may occur. Assuming authentication is working properly and users are able to log on, the most likely causes are as follows:

A known bug exists in the Total Control firmware. Please ensure you are running version 3.6.28 or later. For more information, please contact USR/3Com.
By default, Radius requires that the Shared Secret that is used for authentication also be used for accounting. If no Shared Secret is set up in the USR box, Radius Logs are not created.
