[j-nsp] CoS Implementation/Monitoring

[Blake van Eekeren]

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 ];
     }
}
