The port status is n/a most likely b/c you do not have L1 connectivity to the port.
If you plug something into it, the status should look something like this:
Dot1x Info for interface FastEthernet0/48
----------------------------------------------------
Supplicant MAC
AuthSM State = CONNECTING
BendSM State = IDLE
PortStatus = UNAUTHORIZED
bootp traffic should not be forwarded before dot1x authorization.
Hope this helps.
