N1500 series switch firmware 6.6.0.2 no mac-based authentication anymore?

Switch: N1548

Firmware: 6.6.0.2

Goal: mac-based port authentication with radius

Manual used: Dell EMC Networking N-Series Switches User Guide version 6.6.0.x

following the manual on page 794 top line in the PDF you should be able to do a dot1x port-control mac-based

but:

 

nr31(config-if-Gi1/0/2)#dot1x ?

max-reauth-req           Configure the maximum number of request-Identity
                         requests to be sent.
max-req                  Configure the maximum number of requests to be sent.
pae                      Set the PAE capability mode on the specified port.
timeout                  Configure Dot1x timeout values.

 

the command is not there anymore in this firmware? 

After some research found some commands moved to authentication apparently: 

nr31(config-if-Gi1/0/2)#authentication port-control ?

auto                     Enter auto - for default auto mode.
force-authorized         Enter force-authorized to disable authentication
                         check.
force-unauthorized       Enter force-unauthorized to deny all access through
                         this interface.

but... still no mac-based. 

the same switchtype but with firmware 6.5.3.7 still has the command.

NR32(config-if-Gi1/0/13)#dot1x port-control ?

auto                     Enter auto - for default auto mode.
force-authorized         Enter force-authorized to disable authentication
                         check.
force-unauthorized       Enter force-unauthorized to deny all access through
                         this interface.
mac-based                Enter mac-based to enable Mac-based 802.1x
                         Authentication for this interface.

So. summing things up:

1. firmware 6.6.0.2 does not contain mac-based authentication anymore or am I wrong?

2. It is not documented in the manuals of 6.6.0.x

Anyway: anyone out there that has any idea how to configure mac-based authentication on this firmware version? 

 

Kind regards,
