Authentication configuration under interface is lost after switch reload

[Bahman]

Hello everybody,

I have recently encountered with some issues on my c9300-48P-A, c9300-48T-A switches with 16.12.04 IOS. I configure interfaces by these commands:

interface GigabitEthernet1/0/1

authentication event fail action authorize vlan id
authentication event server dead action authorize vlan id
authentication event no-response action authorize vlan id
authentication event server alive action reinitialize
authentication order dot1x mab
authentication priority dot1x mab
authentication port-control auto
authentication violation restrict

.

.

but after reload of switch, all of these configuration are gone. I got this error during reboot of switch while connected via console :

----------------------------------------

authentication event fail action authorize vlan id
         *
% Invalid input detected at '*' marker.

----------------------------------------

Is this a bug or what is causing this problem?

Thank in advance
