It needs a network interface card wich is compatible with 802.1q standard and that it has linux drivers. The idea is that this equipment is connected to a switch(802.1q compatible) and that it belongs to 3 Vlan's wich are defined in the same equipment. I've got the idea that the 3com model 3c980c-txm would suit me, but i don't know if there are drivers for linux. If anybody has any idea or any helpfull suggestion I'll be gratefull. Thank you...
