Purpose
(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.
(Optional) Specifies the bandwidth-remaining ratio for the
traffic class.
ratio is the value used to determine the amount of unused
bandwidth to allocate to each queue on the subinterface
during periods of congestion. The scheduler allocates the
excess bandwidth relative to other subinterfaces. Valid
values are 1 to 1000. The default value is
platform-dependent.
The router makes no distinction between interface types at
the class level when using the default bandwidth-remaining
ratio. On the Cisco 10000 series router the default
bandwidth-remaining ratio value is 1.
Repeat Steps 5 and 6 for each class queue you want
Note
to define.
Exits policy-map class configuration mode.
Exits policy-map configuration mode.
Creates or modifies a parent policy map. Enters policy-map
configuration mode.
parent-policy-name is the name of the parent policy map.
Configures the class-default class. Enters policy-map class
configuration mode.
The router interprets any features configured under
Note
the class-default class as aggregate features on the
subinterface.
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.
