The Interface Live Viewer is a great tool - allowing you to closely monitor an interface that you're analyzing. I just had an instance where I wanted to look at in/out errors. While I can see the errors regularly collecting, I'm puzzled by the Y-axis label of 'bps'. Interface errors, broadcasts, and multicasts are counted in terms of packets. If a packet is in error, there's no way to tell how many bits were in the packet, from which you could deduce a bps value. So I presume that the value is really 'pps' and that a common axis label is used for Throughput as well as the other variables.
