Chapter 33 Configuring QoS
Creating a Parent Policy Map
Beginning in privileged EXEC mode, follow these steps to create a parent policy map and attach it to an
interface:
Command
Step 1
configure terminal
Step 2 policy-map parent-policy-map-name
Step 3 class parent-class-map-name
Step 4 service policy child-policy-map-name
Step 5 end
Step 6
show policy-map
[parent-policy-map-name [class
class-map-name]]
Step 7
copy running-config startup-config
Attaching a Parent Policy Map to an Interface
Beginning in privileged EXEC mode, follow these steps to create attach the parent policy map to an
interface:
Command
Step 1
configure terminal
Step 2 interface interface-id
Step 3 switchport mode trunk
Step 4 switchport trunk allowed vlan vlan-list (Recommended) Restrict VLAN membership for trunk ports to avoid
Step 5 service-policy input parent-
policy-map-name
Step 6 end
Step 7 show policy-map interface
[interface-id]
Step 8
copy running-config startup-config
This is an example of using multiple parent classes to classify matching criteria for voice and video on
customer VLANs.
Switch(config)# class-map match-any video
Switch(config-cmap)# match ip dscp af41
Switch(config-cmap)# exit
Switch(config)# class-map match-any voice
Switch(config-cmap)# match ip dscp ef
Switch(config-cmap)# exit

Purpose
Enter global configuration mode.
Create a parent policy map by entering the policy map name, and enter
policy-map configuration mode.
Enter the parent class-map name, and enter policy-map class
configuration mode.
Associate the child policy map with the parent policy map
Return to privileged EXEC mode.
Verify your entries.
(Optional) Save your entries in the configuration file.
Purpose
Enter global configuration mode.
Enter interface configuration mode for the interface to which you want to
attach the policy.
Configure the port as a trunk port.
overlapping VLAN membership if the per-port, per-VLAN policy
includes Layer 3 classification.
Attach the parent policy map (created in the previous section) to the
ingress interface.
Return to privileged EXEC mode.
Verify your entries.
(Optional) Save your entries in the configuration file.
