Hi can anyone help me to configure to use dot1x authentication method for my cisco 2960 switch.

I am trying to use microsoft IAS as a radius server.

i configured certificate cervices also and clients & computers are getting certificates.

i configured also my switch to use dot1x authentication as

aaa new-model

aaa authentication dot1x default group radius

interface f0/1

switchport mode access

dot1x system-auth-control

radius-server host 10.0.0.110 auth-port 1645 acct-port 1646 key ****

interface f0/1

dot1x port-control auto

but still my computer cannot connect to the switch

i debug dot1x all

and i got the result which i have attached with this message.
