Hi all,
in a queue like this:
set qos wred 1p2q2t tx queue 1 0:80 0:100
how can i calculate the MPD?
for queue 1 min th is 0 and max is 80 but what's % of drop probability discard?
the same in a queue like this is IOS:
wrr-queue random-detect max-threshold 1 80 100 100 100 100 100 100 100
so i know that max-threshold is 80% of buffer queue and i know default min-thresold but what's MPD?how can i calculate % of dropping beetwen 40% and 80% or (for CatOS examples from 0% to 80%)?
tnx a have nice day

Hello Danilo,
I've checked catos 8.7 documentation for C6500 and MPD is not mentioned.
I think you cannot configure it and this should mean it is fixed to 1 so that drop probability grows from 0 to 1 going from low threshold (that defaults to 0) to 1 at high threshold.
This happens for example also for some linecards of GSR that doesn't allow to configure MPD (if I remember correctly in engine2 linecards)
Hope to help

Hi Giuseppe,
tnx for answering.
seems quite silly not having a way to configure that parameter.
I know that, if not explicit, default should be 1 but could be useful having some stuff like this documented :).
tnx again
Das
