crs-125 dynamic mac based vlan

Since the crs is a layer 3 switch is it possible to configure ports with dynamic mac based vlan?
I want to be possible to connect certain known pc’s in a different vlan when they plug in.
But I don’t know where they will plug in. That is where the dynamic part is useful. The known systems go in a different vlans based on there mac adress. All systems where the mac address is unknown will be in the default vlans.

thanx in advance

Ok found it it was already in the examples :confused:
