Bob: The Shape average command does not use either Bc or Be so
they're irrelevant. Shape average shapes traffic to CIR. Older version of
IOS (12.1) used to shape average traffic to CIR + Bc (even though IOS
documentation showed something different. 12.2 T code trains will shape
average traffic to CIR.
Where this does apply is with the Shape Peak command. The shape
peak command uses both Bc and Be using the formula "average rate (CIR) * Bc
/ Be". Since Bc and Be default to 8000, the formula is CIR * 2 which
results in twice the effective bandwidth over time (assuming wire rate
traffic at CIR * 2.

Thomwin,
No, do not configure the command "frame-relay traffic-shaping" when doing
MQC-based shaping. When doing MQC-based shaping remember that the "shape
average" command automatically sets Be equal to Bc, so set Be explictly to 0
if the task does not require an excess burst. Also remember that if you
want to shape at the DLCI level, using a map-class frame-relay, then you
must shape class class-default.

Hi All,
just want to confirm.
to configure MQC-Based FRTS, should I use frame-relay traffic-shaping
command in main interface ?
In CiscoDoc, MQC-Based FRTS don't have frame-relay traffic-shaping command
in main interface ??
