Switches are not security devices. While it is harder to sniff packets on
switches, you can't count on them to prevent hostile machines on the
switch from playing games with the arp protocol. Also I believe that if
a switch doesn't remember where a particular mac address is it will send
the packet to all of the attached ports.
