Ditto!  Plug laptop_2 into one of the FE ports and see if you get good
speeds between the laptops.  On the 7200, show interface for each of
the FE ports, compare to what the laptops think it has.  Our 7200's
have FE ports that have to be hard coded to get full duplex.  (We no
longer have that issue since almost all 7200's have only GigE ports,
we only have one 7204 with a FE port and it's the only one that's hard
coded to duplex full).
