DOT1x on 3750

I am using 2 3750s some of my studies, but I can not seem to get Dot1x
commands under the interface.
I think I am missing something specific to the 3750, but I dont know what.
I did a brief internet search and saw a few people having this issue but
never saw a resolution.

Globally I configure:

dot1x system-auth-control
dot1x guest-vlan supplicant

when I go to the interface I set the switchport mode to access

int fa1/0/24
switchport mode access

Then the only thing i get for dot1x commands is:

SW2(config-if)#dot1x ?
  credentials Credentials profile configuration
  default Configure Dot1x with default values for this port
  max-reauth-req Max No.of Reauthentication Attempts
  max-req Max No.of Retries
  max-start Max No. of EAPOL-Start requests
  pae Set 802.1x interface pae type
  supplicant Configure supplicant parameters
  timeout Various Timeouts

I do the exact same thing on a 3550 and everything works as expected:

 SW3(config-if)#dot1x ?
  auth-fail Configure Authentication Fail values for this port
  control-direction Set the control-direction on the interface
  critical Enable 802.1x Critical Authentication
  default Configure Dot1x with default values for this port
  fallback Enable the Webauth fallback mechanism
  guest-vlan Configure Guest-vlan on this interface
  host-mode Set the Host mode for 802.1x on this interface
  mac-auth-bypass Enable MAC Auth Bypass
  max-reauth-req Max No.of Reauthentication Attempts
  max-req Max No.of Retries
  pae Set 802.1x interface pae type
  port-control set the port-control value
  reauthentication Enable or Disable Reauthentication for this port
  timeout Various Timeouts
  violation-mode Set the Security Violation mode on this interface

I have checked the IOS on the 3750 and here is the sh ver
