How to Set Up an 802.1x Network and Connect to It with a CEPC (Windows CE 5.0)
802.1x authentication provides authenticated access to 802.11 wireless networks and to wired Ethernet networks. 802.1x minimizes wireless network security risks by providing user and computer identification, centralized authentication, and encryption services based on the Wired Equivalent Privacy (WEP) algorithm. 802.1x supports the Extensible Authentication Protocol (EAP). With EAP, you can use different authentication methods, such as smart cards, and certificates. For more information about 802.1x and wireless technology, visit this Microsoft Web site for a list of links to related technical articles.
Note To successfully complete the steps in the following procedure, you must have extensive knowledge of Windows server administration and networking.
Microsoft used Microsoft Windows 2000 Server for testing purposes. Most of the following steps refer to Windows 2000 Server-related procedures. To obtain additional information about any of these steps, see Windows 2000 Server Help.
To obtain additional information about Windows 2000 Server, visit this Microsoft Web site.
If you use a different server operating system (OS) to set up your 802.1x network, refer to the product-specific documentation.
Microsoft used Cisco** access points for the test scenarios. The access point-related procedures refer to Cisco-based hardware and software. To obtain more information about Cisco products, visit this Microsoft Web site, select the Find a Partner option, and then search for Cisco.
If you use a different access point to set up your 802.1x network, refer to the product-specific documentation.
Hardware and Software Requirements
This document makes the following assumptions:
- Your Platform Builder installation includes CEPC x86 and Emulator x86 board support packages.
- You have a CEPC already configured. For more information, see How to Set Up a CEPC and How to Use the IDE to Create, Customize, and Build a Run-Time Image.
If you encounter problems with any of the steps, refer to the Troubleshooting: Setting Up an 802.1x Network.
