><P
>  The packet size breakdown takes the interface's Maximum Transmission
  Unit (MTU) size and divides it into 20 brackets, each bracket
  containing a range of sizes. As a packet is captured, its size
  is determined and the appropriate bracket is incremented.</P
><P

  your network, and can aid in network (re)design decisions.</P
