Yeah. That's because you are specifying the MAC address. Anyone, please
correct me if I'm wrong.

Look this,
interface FastEthernet0/1
switchport access vlan 10
switchport mode access
switchport port-security
switchport port-security violation protect
switchport port-security mac-address 0009.b7da.4140
!
with the configuration above, without config "maximun 1" works as expected,
#sh port-security
Secure Port MaxSecureAddr CurrentAddr SecurityViolation Security

(Count) (Count) (Count)
