Extensible Authentication Protocol (EAP) is an optional IEEE 802.1X security feature designed for large enterprises with a vast user base and access to an EAP-enabled Remote Authentication Dial-In User Service (RADIUS) server, such as Cisco Secure ACS 2.6 or Windows 2000 RADIUS. The RADIUS server uses EAP to provide authentication service for EAP-enabled clients.
Server-based authentication can be enabled for your client adapter in one of two ways:
_ Through a host device and code built into its operating system (referred to as EAP)
_ Via your client adapter’s firmware and Cisco software (referred to as LEAP) _ This method provides authentication service to client adapters whose host devices are not running an operating system with built-in EAP support. The term LEAP is used to distinguish authentication provided by the client firmware from authentication provided by a host and its operating system.
To Set up the parameters:
Enter your username in the Username field.
Enter a password in the Password field. (Passwords are case sensitive and must contain at least eight characters.)
If you have not enabled LEAP and WEP, check the Enable LEAP and Enable WEP checkboxes in the Basic Properties screen, the RF Network Parameters screen (if you are using an office network), or the Home Networking screen (if you are using a home network). Once LEAP and WEP are enabled, your client adapter authenticates to the RADIUS server using your username and password and receives a session-based WEP key.
