I am facing a problem in input queue drops in my router. I am getting input drops in my Fast Ethernet interface. If I am replacing this with a Gigabit interface, I am not getting any drops. I can see that that max input queue length of both interfaces are 75. So why is it not dropping in gigabit interfaces?
I understand that Fast ethernet is 100 Mbps and that means it can process 100 Mb of traffic per second. Is it same for incoming traffic also.
Where does this input queue come into picture? Is it when the tx-ring is full?
