Detecting precedence of 5, under 40 no packets will be dropped, between 40
and 60 it will random drop, at 60 pps, 1 out of every 20 will be dropped.

I seem to remember something like the mark probability denominator is the
amount of packets dropped between the min and max (40 and 60 in your case)
and everything over 60 is dropped always.

Let me know your findings.

Hi all,
I am trying to interpret the last parameter of this command.
At the router it is showing as following;
 
r4(config-if)#random-detect precedence 5 40 60 ?
  <1-65536> mark probability denominator
  <cr>
 
r4(config-if)#random-detect precedence 5 40 60 20
 
Does this mean that if the number of packets exceed the range of 40 to 60,
the router would randomly drop the packet at the rate of 5%, a packet for
every 20 packets?
Did I interpret it correctly?
 
Thanks a lot.
 
JP
