I have been trying to make some sense out of a weeks worth of measurements we made every three minutes on the local network.  The first problem that I have is that the input Q discards do not seem to be correlated with the load on the router.  By load, I mean either input packets, input bytes, or total load (sum over interfaces of input + output).  Can someone tell me the precise definition of input q discards and what conditions lead to them?

A second problem is that the sum of input and output bytes on an interface do not agree with traffic counts generated by an EtherMeter.  Is this because the input bytes counted refer only to traffic accepted for forwarding by the router and do not include purely local traffic on the attached sub-net?
