Configuring the Parent QoS Policy
To configure the parent QoS policy, enter the following commands beginning in global configuration
mode:
Step 3
Router(config-pmap-c)#
priority
Configures a traffic class as a priority queue.
Note
In Cisco IOS Release 12.0(25)S and Release 12.3(7)XI,
and later releases, this command has no arguments. To
specify a bandwidth rate, use the
police
command. For
more information, see
Chapter 6, “Policing Traffic.”

Configures single-rate traffic policing based on bits per second or
as a percentage of the parent policy’s shape rate, or configures
two-rate traffic policing based on bits per second.
(Optional)
cir
is the committed information rate (CIR) and
indicates an average rate at which the policer meters traffic. CIR
is based on the interface shape rate.
percent
percent
indicates to use the percentage of available
bandwidth specified in
percent
to calculate the CIR. Valid values
are from 1 to 100.
[
bc
]
burst-normal
and [

]
normal-burst-in-msec
specify the
normal or committed burst size (CBS) that the first token bucket
uses for policing traffic. Specify the
burst-normal
value in bytes
and
normal-burst-in-msec
value in milliseconds (ms).
[
be
]
burst-excess
and [
be
]
excess-burst-in-msec
specify the
excess burst size (EBS) used by the second token bucket for
policing. Specify the
burst-excess
value in bytes and
excess-burst-in-msec
value in milliseconds (ms).
[
be
]
peak-burst
is the peak information rate (PIR). Indicates the
rate at which the second token bucket is updated. The
pir
specifies
the PIR value in bits per second.

Chapter 6, “Policing Traffic.”

mode.
policy-map-name
is the name of the policy map.
Step 2
Router(config-pmap)#
class
class-default
