Configuring Traffic Shaping

Traffic shaping allows you to control the traffic exiting an interface to match its transmission to the speed
of the remote target interface and ensure that the traffic conforms to policies contracted for it.
Shaping performed on incoming and outgoing interfaces is done at the Layer 2 level and includes the
Layer 2 header in the rate calculation.
Restrictions
The bandwidth, priority, and shape average commands should not be configured together in the same
class.
