Re: PEAP How To?

PEAP is hybrid process ( combination of leap and eap tls )

To download server side certificate on ACS you can use eap tls doc.

Depending on AP use either of following doc

You have to careful while selecting the client supplicant , you can choose Cisco peap supplicant or Microsoft peap supplicant

You can have Microsoft peap supplicant or Cisco Peap supplicant .

If you have windows 2000 OS , than if you load service pack3 , Microsoft peap supplicant is installed . On top of this if you install ACU 5.05 microsoft supplicant wil be overwritten by Cisco supplicant .

In case of XP , if you install service pack 1 , it will install microsoft peap supplicant , if you install ACU 5.05 it will be overwriteen by Cisco Peap supplicant .

Microsoft peap supplicant send eap-Chap in EAP tunnel and Cisco support EAP-GTC in eap tunnel .

with non cisco card it depends on which radius server and database you are running .

At present ACS 3.1 supports EAP-GTC so it will not interoperate with Microsoft supllicant . In later release ACS will have support for EAP-Chap so

that you can use 3rd party card with Microsoft supplicant and ACS3.2
