debug radius

What are you pointing to 802.1x? ACS or Windows 2003/IAS or Windows 2008/NPS ?

On client run Wireshark with Filter = EAPOL
On Radius server run Wireshark with Filter = RADIUS

To the dot1x gurus..,

I have been using dot1x for our wireless network for a while now and its
been running smooth. I decided to test
dot1x for Wired connections. unfortunately, its not working. for 3 days now,
i have no idea what am doing wrong.

Here is a debug

switch#test aaa group radius cisco cisco123 legacy
Attempting authentication test to server-group radius using radius
User was successfully authenticated.

The weirdest thing is, when i log in with my pc to my domain with the
username and password, cisco & cisco123, the ACS log does not
even see my username (obviously it seems like the switch is not sending this
information to the ACS)

my dot1x configs are pretty standard

dot1x system-auth-control
dot1x guest-vlan supplicant

aaa authentication login default group radius
aaa authentication dot1x default group radius
aaa authorization network default group radius
aaa accounting dot1x default start-stop group radius

radius-server host 192.168.2.253 auth-port 1000 acct-port 1001
radius-server key 7 xx

interface FastEthernet0/1
 switchport mode access 5
 authentication event fail retry 1 action authorize vlan 4
 authentication event no-response action authorize vlan 4
 authentication port-control auto
 dot1x pae authenticator
 spanning-tree portfast
end

==
#sh vlan | in dot1x

5 Staff_dot1xTest active
4 Student_dot1xTest active Fa0/1

Any input, much appreciated!

Thanks,
