I'm finally on the receiving end of a vlan problem :) I want to be able to use multiple VLANs with the same MAC addr through an SMC switch. But, it disables traffic because it thinks we have a loop or something like that. I know there is a way to disable this on (most?) cisco switches, and I'm hoping it can be done on SMC as well. If anyone knows the cisco and/or SMC methods of letting multiple VLAN devices with the same MAC communicate, please let me know. For what it's worth, Netgear switches work out of the box...
