You have allocated the correct number of buffers for your distance and speed on an extended
distance link over dark fiber. However, you notice that there is a latency issue being reported on
the port. The port is repeatedly buffer starved.
What is a common reason for this performance problem over the distance link?
There is protocol conversion on each end of the link.
There are frames with small payload size.
There are frames with full or near full payload size.
The front-end port de-bounce 100 ms is too low.
