I'm having a strange issue. We have a router that is connected to an OC12 and it is sending ingress netflow data on all layer 3 interfaces.
The thing that I'm seeing is that the bandwidth utilization will go over the bandwidth of the OC12. I've seen spikes as high as 900Mbps.
Now these are only spikes and will only appear over a one minute sample, so it is not something that's maintained, but it is still an issue because now I'm afraid that I'm getting bad data.
