Troubleshooting

There are no troubleshooting steps for this task.

Using Cisco LEAP

Light Extensible Authentication Protocol (LEAP) removes the requirement to configure static WEP keys on the Cisco Aironet 1200 AP and the Cisco 7920. The LEAP server (Cisco Secure ACS, in this case) is responsible for providing the WEP keys to the wireless clients through the 1200 AP.

A complete explanation of this process is beyond the scope of this document. Refer to Wireless LAN Security White Paper for further information.

Note: That document also contains some instructions to configure the Cisco Aironet 1200 AP and the Cisco Secure ACS. Use the instructions in this section instead, because they were written specifically for this document.

Configuring the Cisco 7920

The instructions in this section guide you through the minimum steps that are required to configure the Cisco IP Phone 7920 to use LEAP authentication.

1.Turn on the Cisco 7920.

2.Choose Menu > Phone Settings > USB Enable / Disable [Enable] to enable the Cisco 7920 USB port.

3.Connect the Cisco 7920 to the USB cable. (The USB cable should already be connected to the PC.)

4.Start the Cisco 7920 Configuration Utility.

5.Log in to the Cisco 7920.

The default User Name is Admin. The default Password is cisco. Click OK.
