I don't think so, I guess the switch perform a sort of arpping in order to
detect who have a macaddress assigned,
No, he's right. If the MAC to port mapping has not been learned by
the switch, the packet is flooded to all ports or (for really bad
switches) dropped. A switch is a pure layer-two device and ARP
involves layer-three addresses and concepts.
We have some switches that are able to do ip routing too... :-(
I have to admint that I'm not a switch specialist but given the ability to do
routing I was imagine the arpping trich...
