Usage Guidelines
For shape average commands in the child policy, the reference used for percentage parameters is relative to
the maximum rate of the parent. If shaping or policing is not configured on the parent, then the parent inherits
the interface rate.
If you have both shape and bandwidth configured for a class, ensure that the shape percent value is always
greater than the percent value for bandwidth.
The shaper parameters, used to override the locally-configured values in BNG, can either be sent to BNG by
the RADIUS server during connection establishment, as CISCO VSAs in an Access Accept message, or can
be sent to BNG as part of the CoA messages.

Examples
This example sets traffic shaping to 50 percent of the parent shaper rate:
RP/0/RSP0/CPU0:router(config)# policy-map policy1
RP/0/RSP0/CPU0:router(config-pmap)# class class1
RP/0/RSP0/CPU0:router(config-pmap-c)# shape average percent 50
This example shows how to set traffic shaping to 100000 kbps:
RP/0/RSP0/CPU0:router(config)# policy-map policy1
RP/0/RSP0/CPU0:router(config-pmap)# class class1
RP/0/RSP0/CPU0:router(config-pmap-c)# shape average 100000 kbps
This example shows how to set the default value of QoS shape-rate variable (shaper4) as 100000 kbps, in
BNG:
RP/0/RSP0/CPU0:router(config)# policy-map policy1
RP/0/RSP0/CPU0:router(config-pmap)# class class1
RP/0/RSP0/CPU0:router(config-pmap-c)# shape average $shaper4 = 100000 kbps
