Purpose
Applies the parent policy to the subinterface.
input indicates to apply the service policy to inbound
traffic.
output indicates to apply the service policy to outbound
traffic.
parent-policy-name is the name of the parent policy map.
The router shapes the subinterface traffic to the shaping rate
specified in the parent class-default class and applies the
QoS actions specified in the child policy to traffic matching
the traffic classes.
During periods of congestion, the router uses the
bandwidth-remaining ratio specified in the parent policy
map to allocate unused bandwidth on this subinterface
relative to other subinterfaces.
Purpose
Creates or modifies a child policy map. Enters policy-map
configuration mode.
child-policy-name is the name of the child policy map.
Configures the class map that you specify. Enters
policy-map class configuration mode.
class-map-name is the name of a previously created class
map.
(Optional) Shapes the average or peak rate to the rate you
specify.
average specifies average rate shaping.
peak specifies peak rate shaping.
cir specifies the committed information rate (CIR), in bits
per second (bps).
(Optional) bc specifies the committed burst size, in bits.
(Optional) be specifies the excess burst size, in bits.
