It really was meant to be an L3 device - You had to do BVI's to put a vlan on
multiple ports.  The FE ports couldn't do ACLs - You had a 'special command'
to force traffic to route out of the GE port and back again to apply ACLs
there.  However, the 'special command' only applied to IP packets without
options - if someone sent IP options, IPX, AT, NetBIOS, etc, you were shafted.
I'm sure there are other reasons too.  It was rubbish.
