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.”
Step 4
Router(config-pmap-c) police [cir] bps
[bc]
burst-normal [be] burst-excess
[conform-action action] [exceed-action
action] [violate-action action]
or
Router(config-pmap-c)# police [cir]
percent percent [bc] normal-burst-in-msec
[be]
excess-burst-in-msec [ conform-action
action] [exceed-action action]
[violate-action action]
or
police {cir cir} [bc] burst-normal [pir
pir] [be]
peak-burst [conform-action
action] [exceed-action action]
[violate-action action]
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 [bc] 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.
For more information, see Chapter 6, “Policing Traffic.”
Command Purpose
Command Purpose
Step 1
Router(config)# policy-map
policy-map-name
Configures the parent policy. Enters policy-map configuration
mode.
policy-map-name is the name of the policy map.
Step 2
Router(config-pmap)# class class-default
Configures the class-default class in the parent policy. Enters
policy-map class configuration mode.
