[c-nsp] shaper in policy-map is not taken into account

Hi,

I have configured 20Mbps shaper("shape average 20000000") in
SHAPER-EGRESS-TRAFFIC policy-map under class-default traffic class:

  Service-policy output: SHAPER-EGRESS-TRAFFIC

          Match: any


During the last 30 seconds, policy-map has allowed traffic at 2.1Mbps
in average and dropped 17kbps in average. Why is my policy-map
dropping traffic while it should shape it? And shaping is configured
to 20Mbps not around 2Mbps..

Martin
