Using Open Authentication and Static WEP Keys

If you want to learn more about Wireless Security before you start this section, refer to these documents:

∙Cisco Aironet Wireless LAN Security Overview

∙Security Setup for the Cisco Aironet 350

∙Wireless Virtual LAN Deployment Guide

This example is based on the use of open authentication and 128−bit static Wired Equivalent Privacy (WEP) encryption keys.

Caution: It is not recommended to use Shared Key authentication because it is very easy to compromise.

This task guides you through a very basic Cisco 7920 and Cisco Aironet 1200 AP configuration. This configuration allows the Cisco 7920 to authenticate and associate with the 1200 AP. When you are done, the Cisco 7920 should be able to register with the Cisco CallManager server.

Note: When you are using open authentication, the Cisco Aironet 1200 AP will authenticate all devices that send it authentication requests. However, only devices with the correct WEP encryption keys will be able to associate with the 1200 AP and to send traffic over it successfully.

Configuring the Cisco 7920

This subtask assumes that you have already installed the Cisco 7920 Configuration Utility that came with your Cisco 7920. If you have not yet installed this utility, stop and do so now. The instructions for the installation are included with your Cisco 7920.
