DOCUMENT:Q230786 10-AUG-2001 [winnt] TITLE :How to Enable RADIUS Port for Network Monitor PRODUCT :Microsoft Windows NT PROD/VER::4.0 OPER/SYS: KEYWORDS: ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Windows NT Server version 4.0 - Microsoft Windows NT Workstation version 4.0 ------------------------------------------------------------------------------- SUMMARY ======= If you use Network Monitor in Systems Management Server version 1.2 or Network Monitor from the Windows NT Server version 4.0 compact disc, you are not able to view Remote Authentication Dial-In User Service (RADIUS) packets. Network Monitor in Systems Management Server version 1.2 or Network Monitor from the Windows NT Server version 4.0 compact disc does not parse RADIUS traffic. Network Monitor must be upgraded to Network Monitor version 2.0. After Network Monitor has been updated to version 2.0 and RADIUS is configured to use port 1645 and 1646 for Authentication and Accounting, you are able to view RADIUS traffic in a Network Monitor trace. According to RFC 2026 the ports used by RADIUS have been changed to 1812 and 1813 for Authentication and Accounting, respectively. MORE INFORMATION ================ To view RADIUS packets using RFC-compliant ports 1812 and 1813: 1. In the parsers directory created by Network Monitor, edit the Tcpip.ini file. 2. In this file, find the [UDP_HandoffSet] section. 3. At the bottom of this section, locate: 1645 = Radius 1646 = Radius 4. Change 1645 to 1812 and 1646 to 1813. 5. Save the file. When you run Network Monitor, you now see RADIUS session packets initiated by RADIUS.
