CoS Implementation/Monitoring

I guess you are not filling up interface. During your
capture you had
approximately 2Mbps traffic on 100Mbps interface. So packets
do not get
queued in buffers and since thresholds are not reached RED
does not kick
in...

Try with limiting bandwidth for data traffic with
schedulers...

Subject: [j-nsp] CoS Implementation/Monitoring

Hello:

I have been attempting to apply a basic CoS implementation
on an M40. 
The appropriate traffic is classified properly, however
something does
not jive.  Even with a pegged interface the RED-dropped
packets counter
never increments.  I have a data drop profile implemented in
the
scheduler for that interface, which applies a rather
generous drop
schema.

This makes me think that I do not have the profile applied
to the
interface properly, yet all the documentation I read proves
otherwise. 
I have passed this issue through numerous people, yet nobody
can seem to
explain it.  I would greatly appreciate any input at all.

Thanks.

data-drop-profile {
     interpolate {
         fill-level [ 60 70 80 90 95 ];
         drop-probability [ 70 80 90 97 100 ];
     }
}
