sorry, I still do not understand. 

I run "show interfaces" on the M160 with three POS
sampled. The results:


  Input rate     : 2057187176 bps (572668 pps)
  Output rate    : 1898785304 bps (619012 pps)

  Input rate     : 2047617800 bps (563212 pps)
  Output rate    : 1925071056 bps (615424 pps)


  Input rate     : 2148126912 bps (612172 pps)
  Output rate    : 2061728912 bps (655415 pps)

The total packet rate is : 3637903pps. It exceed the
capacity just a little, so I think it's not the
situation that it should have 2/3 traffic missed.
