Jimmy,

 

I haven't tested with Win 7 so I wasn't sure.  You will need to enable
certificates in ACS and go thru the process of enabling PEAP.  As mentioned
by the failed log the protocol type is unknown as it hasn't been enabled by
default.

I know, it´s a bit confusing. But in windows7 eap-md5 is not mentioned.This
is how it looks on my win7-computer:

Jimmy,

 

By default EAP-MD5 is the only protocol enabled but make sure you check it
as Piotr has suggested.  But on the Windows Client you hare using PEAP.
Change that to EAP-MD5.

Jimmy,

Have you enabled EAP-MD5 under the "Global Authentication" section on the
ACS?

Hi

 

I am doing my first attempt ever to setup 802.1x. I know the basic idea with
EAP-types and radius, but I cant get it to work. Fact:

 

c2970. Configured like this:

 

aaa new-model

!

!

aaa authentication login default none

aaa authentication dot1x default group radius

aaa authorization network default group radius 

!

interface FastEthernet0/19

 description T43

 switchport mode access

 dot1x pae authenticator

 dot1x port-control auto

 dot1x violation-mode restrict

 dot1x auth-fail vlan 1

 spanning-tree portfast

!

radius-server host 192.168.1.51 auth-port 1645 acct-port 1646 key cisco

radius-server vsa send authentication

 

The ACS is setup with a username/password, I have configured the network
device and all that jazz...

 

On port Fa0/19 I have my windows7-client that cant connect. It prompts me
for username/password and saids "authentication failed". Debug of
radius/dot1x on the switch show me that I get a "Access-Reject" back from
the ACS. The ACS saids "EAP Type not configured" in failed-attempts. But the
EAP-type column is empty.

 

My gess is that there is something misconfigured in the win7-supplicant. I
have:

* Enabled dot1x-authentication.

* chosen method: Microsoft PEAP (not "Smart card or other certificate")

* Under settings I have unchecked "Validate server certificate"

* Under settings I have chosen "Secured Password EAP-MSCHAP v2" as
authentication method.

 

But what am I doing wrong? Can I get more debug-output from my win7-client?
Or should I try with a third-party supplicant instead?

 

Also, is the "dot1x pae authenticator"-command on the switchport needed in
my case?

 

Can I get more detailed output from ACS than the default-info in the
failed-attempts-log?

 

Thanks in advance!

 

Br Jimmy
