Traffic direction: the negative y-axis measures the traffic out from the RIX towards the connected party and the positive y-axis is traffic into the RIX from the connected party.
Note that the RIX switches are mostly cut-through. This can mean that errored input packets may be seen on your interface if any of your peers is experiencing output errors. That is, you may see input errors on your interface towards the RIX even when your circuit to the RIX is clean.
