Dears,

we have fingerprint machines, when connecting the machine to a port configured for dot1x the dot1x authentication fails, and MAB authentication keeps in running state as the result below. the mac address keeps unknow

Interface: GigabitEthernet3/0/7
          MAC Address: Unknown
           IP Address: Unknown
               Status: Running
               Domain: UNKNOWN
      Security Policy: Should Secure
      Security Status: Unsecure
       Oper host mode: multi-domain
     Oper control dir: both
      Session timeout: N/A
         Idle timeout: N/A
    Common Session ID: 0A0A6507000032815AE3D7D3
      Acct Session ID: 0x000097C0
               Handle: 0x8F000394

Runnable methods list:
       Method   State
       dot1x    Failed over
       mab      Running

and i receive the message below

%DOT1X-5-FAIL: Authentication failed for client (Unknown MAC) on Interface Gi3/0/7 AuditSessionID 0A0A6507000032965B2927BB
%AUTHMGR-7-RESULT: Authentication result 'no-response' from 'dot1x' for client (Unknown MAC) on Interface Gi3/0/7 AuditSessionID 0A0A6507000032965B2927BB
%AUTHMGR-7-FAILOVER: Failing over from 'dot1x' for client (Unknown MAC) on Interface Gi3/0/7 AuditSessionID 0A0A6507000032965B2927BB

no port security is configured on the port.

when we remove the dot1x configuration and configure port security we see the machine mac address on the port.

switch ios Version 15.0(2)SE10a switch hardware 3750 stacked.

please advise,

Thanks in advance.

Hi Maher,

Could you change the authentication order and make it 'mab' first then dot1x and check the status?
