Setting Up MAC-Based Authentication

Setting Up MAC-Based Authentication

MAC-based authentication allows only client devices with specified MAC addresses to associate and pass data through the access point. Client devices with MAC addresses not in a list of allowed MAC addresses are not allowed to associate with the access point.You can create a list of allowed MAC addresses in the access point management system or on a server used for MAC-based authentication, and you can enable MAC-based authentication on one or both of the access point radios.

This section provides instructions for:

•Enabling MAC-Based Authentication on the Access Point

•Authenticating Client Devices Using MAC Addresses or EAP

•Enabling MAC-Based Authentication in Cisco Secure ACS

Enabling MAC-Based Authentication on the Access Point

Follow these steps to set up and enable MAC-based authentication on the access point:

Step 1 Follow this link path to reach the Address Filters page:

a.On the Summary Status page, click Setup.

b.On the Setup page, click Address Filters under Associations. Figure 8-10shows the Address Filters page.
