with acs 4.2 installed in my network, PEAP, EAP-TLS, md5... authentications work normally. But Mac-Based-Authentication doesnt work at all. i tested every thing but no luck .
This is what i have setup on Swith for MAB:
aaa new-model
aaa authentication login default none
aaa authentication dot1x default group radius
radius-server host 192.168.2.16 auth-port 1645 acct-port 1646 key cisco
!
dot1x system-auth-control
!
interface FastEthernet0/1
switchport mode access
dot1x pae authenticator
dot1x port-control auto
dot1x mac-auth-bypass
On ACS server, i created Netword-Profile for MAB, i added those Agentless hosts mac-adds, Even i created User-Name&password by those Agentless hosts mac-adds on acs, ..... still nothing seems to be working. i have selected ACS_Internal-Database for mac authentication.
On ACS while i check the Failed-attempt log, nothing is logged there. i dont know where is the issue.
Please tell me where im wrong on my config?

You need to enter "mab" under the interface configuration. That will allow mab based authentications on the interface. Please note that the 802.1x timer and re-tries would have to time out before mab occurs. If you are still having problems please past the output of this command:
show authentication session interface interface_name_address
For more info on MAB you can take a look at the following guide:
