Scenario:  I work for a huge company that has 7,000 employees in a
single campus, with more than that many PCs, Servers, printers, etc,
each having a MAC address.  I'm doing layer 2 switching campus wide, and
only routing at the network edge to/from the internet/wan provider.

I'm in a tech lab, and I need to jack in a small switch for testing
servers.  People all over the campus are going to need to hit the test
servers.  Thus, this little 8 port switch in my lab needs to be able to
store more than 7,000 mac addresses.

Maybe not the best scenario, but it's a valid one.
