cur/low I suppose when we have underruns and overruns going on.
What i want to know is the meaning of the output. In case of curr/max its very clear.
input queue (curr/max packets): hardware (0/7)
output queue (curr/max packets): hardware (0/13)
Above means (correct me if I am incorrect), there are Zero packets currently in input queue, and 7 were the max packets seen at one time. For output queue, zero are the current packets in ouput queue and 13 were max that were seen in output queue. This is documented.
Still you are missing my main point. I want interpretation for,
input queue (blocks free curr/low)
output queue (blocks free curr/low)
"blocks free curr/low" <------
curr/min blocks: 511/408
When you say Currently there are 511 blocks in hardware queue 0, and the minimum blocks were 408. This means 511 blocks free? or currently engageged? and 'minimum blocks were 408' means at peak utilization there were 408 free? or used? Does this statistics how high water mark blocks or they are just random?
