PBA setting for multiple mac on one port

Hi, there!

As for subject, i’m trying to configure PBA to set one port with multiple MAC, and so multiple VLAN.
I’ve already configured PBA to recognise a MAC from a MAC List, and conseguently set the port Hybrid with a precise VLAN.
It just happens frequently that a little switch, or, saying, an IP Phone with a PC connected to it, is plugged to a CnMatrix port. So, i would have a MAC-to-VLAN for Phone and a MAC-to-VLAN for PC on the same port.
Is it possible? Any suggest for this topic?
Many Thanks,
Antonio D’Affuso
