Enabling EAP in Cisco Secure ACS
Cisco Secure Access Control Server for Windows NT/2000 Servers (Cisco Secure
ACS) is network security software that helps authenticate users by controlling
access to a network access server (NAS) device, such as an access server, PIX
Firewall, router, or wireless access point or bridge.
Cisco Secure ACS operates as a Windows NT or Windows 2000 service and
controls the authentication, authorization, and accounting (AAA) of users
accessing networks. Cisco Secure ACS operates with Windows NT 4.0 Server and
Windows 2000 Server.
Note You must use ACS version 2.6 or later to set up the access point in ACS.
Follow these steps to include the access point as a Network Access Server (NAS)
in Cisco Secure ACS:
Step 1 On the ACS main menu, click Network Configuration.
Step 2 Click Add New Access Server.
Step 3 In the Network Access Server Hostname entry field, type the name you want to
assign to the access point as an access server.
Note This field does not appear if you are configuring an existing NAS.
Step 4 In the Network Access Server IP address box, type the access point’s IP address.
Step 5 In the Key box, type the shared secret that the TACACS+ or RADIUS NAS and
Cisco Secure ACS use to encrypt the data. For correct operation, the identical key
(case sensitive) must be configured on the access point’s Authenticator
Configuration page and in Cisco Secure ACS.
Step 6 From the Authenticate Using drop-down menu, select RADIUS (Cisco Aironet).
Step 7 To save your changes and apply them immediately, click the Submit + Restart
button.
