Hello, thanks for the quick answer

Cisco MAB is a *method* you configure on the switch. it still needs a backend
to send the request to - eg a RADIUS server

Yes, of course I'll have to use a Radius server, and many forums say that if you put the Mac address in both username and password, it will authenticate if - in the switch - you use Mab... And that's exactly what I tried to do, but it did not authenticate... Am I doing sth wrong?

the example VMPS stuff provided gives a clear start. you can either have a flat list
of MACs or stick then into a DB and have the VMPS module query the DB.

So correct me if i'm wrong : I'll have to uncomment the mac2vlan on vmps file, add MAC-ADD,VLAN-NAME to mac2vlan, change the listening port to 1598 and the auth type to vmps on radiusd.conf, and that's that?

It's just that... I don't exactly see how dynamic vlan assignment works if you only use a flat list, vmps only shows how to query the DB..

Thank you Alan.
