Hello folks

Does anyone know what does "bytes" and "bytes delayed" mean when you do
a sho traffic-shape stat

Is "bytes" the total outbound bytes on the PVC?? If so, how can it be
smaller than "bytes delayed"??

This is because in your case bigger packets (that is, more bytes) have been
delayed in the traffic shaper's queue, so that's why you have more bytes
under delayed column...
If you look into packets counter instead of bytes counter then you will
notice that you have less packets counted under delay column then that you
have under total packets counter...

B.R.

Igor, Thanks for the note, actually that is not what I am referring to.
The router was showing an anomaly when you do a show traffiic-shap
stat. The delayed bytes should never be more than the total bytes,
worst case they can be equal, but normally the delayed will be less
than the total, ideally delayed should be no more than 50% of total
bytes.
