Thanks for the replies. The two MAC addresses would come from the two PC's in an office. The would both connect in to a hub and then the hub would uplink to the cisco switch. I need one pc in VLAN1 and one pc in VLAN2, from what you and Dennis stated this will not work. I appreciate the comments though.
