You'll see several mac addresses on one port if that port is connected to
another switch or hub. In that case, the mac you're looking for is not
attached directly to the switch you're viewing. Hop over to the next switch
and repeat the "show cam dynamic". If it's on a port by itself, you've
found it. If it's on a shared port, then hop again to the next switch, ...
until you find it.
