I am trying to setup wired machine based authentication. I have followed this guide
However I simply get the same error all the time on ACS.
Invalid message authenticator in EAP request
switchport access vlan 20
switchport mode access
dot1x pae authenticator
dot1x port-control auto
dot1x guest-vlan 20
i am trying to setup group matching to perform vlan assignment however I am just entering under the unknown user policy at the min with no vlan assignment setup.
Anyone shed any light on this, all I want to do is authenticate a machine via certificates issue a vlan id based on the machine name and AD group matching. No user authentication this can be done via the PDC.
Purely using machine auth.
I recommend to change/retype the shared secret on the switch as well as ACS server for the
AAA Client and AAA server.
