I have to configure in a wired and wireless network 802.1x and I do not know which components I need. ACS or NAC appliance?

Hi,


802.1x is an authentication mechanism for devices at the port level (L2).

Can be wired or wireless.


Here's what you need:

A client (Windows computer, end user device 802.1x compliant)

An authenticator (switch, AP)

An authentication server (Radius)


The intention is to authenticate the user as soon as detecting L2 activity, for example when a user plugs the computer to an available port on a switch.


You can do a quick test with the following components:

Client (Windows computer)

Authenticator (Cisco Switch)

Authentication Server (ACS)
