Sorry, I meant classifying traffic by using filters on each of the MLPPP
LSQ bundles.

I assume that you are classifying traffic by using filters on each of
the T1s. Can you post those filters? They are also not applied to the
LSQ interface in the original post. If you don't have the filter
applied to the LSQ logical interface, your traffic will not get
classified and therefore all will be in the BE queue.

This is not working, even with enabling per-unit schedular on
constituent
link and applying schedular-map to their logical unit in Class of
Service
Interface hierarchy as u suggest.
Results are same, while pushing Gold, Silver or BE traffic, i.e. all
goes to
queue 0 (BE). And in lsq interface, there is no Queue stats available
(all
Queue stats are 0).

Well is it necessary to implement the fragmentation map, multiclass or
LFI
settings. as we are not implementing these.
Does any one has the practical implmentation experience to implement CoS
over MLPPP, if yes than please share your sample configuration and
comments
on this issue.
Thanks and Regards
