170 Cisco Radio
VX5 Reference Guide E-EQ-VX5RG-G-ARC
WPA for the Cisco Radio
Wi-Fi Protected Access (WPA) is only available on VX5’s equipped with the
Microsoft Windows XP operating system.
LXE recommends the VX5 have Windows XP Service Pack 2 (SP2) installed.
Although Microsoft patch #Q815485 also provides WPA functionality with
previous versions of Windows XP, this version was not tested by LXE. All
configuration examples shown in this section are from a VX5 with SP2 installed.
Please refer to the “LXE Security Primer” to prepare the Authentication Server and
Access Point for VX5 communication.
System Requirements
To support Wi-Fi Protected Access (WPA), the VX5 must be equipped as follows:
• Windows XP SP2
• Cisco 350 radio card
The LXE VX5 computer supports WPA and all authentications. The Microsoft supplicant and
Cisco supplicants are used separately or together to provide support for the different
authentications.
WPA support was added to Microsoft XP with SP2. Prior to SP2 there was a patch available that
would add WPA support. This document will show configuration of Windows XP with SP2
installed. Most of the configuration is done with the Microsoft Wireless Configuration tool.
However for WPA/GTC the Cisco supplicant (ACU) must be installed and configured to allow
Microsoft to configure the Cisco radio. Additionally WPA/LEAP requires the Cisco supplicant
and configuration tool.
