Hi Sean/Brian/Erick,
Thanks for your mails. So I can conclude with MQC based FRTS BECN based
adaptive shaping is activated the moment "shape adaptive" is configured
in the policy map.
This can be verified using the "show policy-map interface" command.
Regards,
Pankaj K

So, comparing MQC to old way:
shape average 768000 7680 0
is same as
map-class frame-relay 128k
frame-relay cir 768000
frame-relay bc 7680
frame-relay be 0
frame-relay mincir 768000
Right?
Would you apply the shape command to all classes under
the policy so all traffic gets shaped the same?
