    Get a packet sniffer (something like Ethereal ) and search for ARP, RARP, BOOTP or DHCP-packets. Some of those (when the client gets an ip-address assigned) contain both IP and MAC address. Be carefull, each packet could have two: one pair of the server, one of the client. Read some RFC on the protocols to understand where you should look.

    Here's the RFC for DHCP

    I dont think you got the message :=)

    There are 16 ports on the switch

    they are named 1 to 16.

    If i discover a person abusing the network and i know hes mac adress is 00-54-FC-80-C0-56 then i want to ask the switch, "in which port is this guy connected"

    Can you help me with that?
