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.
