Hi, group

   I want to account the traffic amount of my router's
interface, see the result below, the input rate and output
rate is too slow! Although it is the main interface of my
company . 2000 people's company.
Why so slow ? What is the correct way to account the
traffic of one interface of a router or a switch?

Thanks alot
