Configuring QoS Policy Actions and Rules
The second step in creating a QoS service policy is to define how you want the router to handle the
packets that match the classification rules you defined in
Chapter 2, “Classifying Traffic.” The
Cisco 10000 series router supports a modular CLI element called a policy map to enable you to configure
a QoS policy with the appropriate actions and rules.
This chapter describes how to create QoS policies that the Cisco 10000 series router applies to specific
traffic classes. It includes the following topics:
• QoS Policies, page 3-1
• Types of QoS Actions, page 3-4
• Policing Actions, page 3-11
• QoS Inheritance, page 3-12
• Traffic Subject to QoS Policies, page 3-17
• ATM Virtual Circuits Without QoS Policies, page 3-17
• QoS Performance, page 3-18
• Configuring QoS Policies, page 3-18
• Verifying QoS Policy Configurations, page 3-20
• Related Documentation, page 3-23
QoS Policies
After the Cisco 10000 series router classifies traffic based on the classification rules applied on an
inbound or outbound interface, the router needs to know how to handle the traffic that meets the
matching criteria. A modular quality of service command-line interface (MQC) element called a policy
map enables you to create QoS policies that tell the router the QoS actions and rules to apply to packets
belonging to a particular traffic class.
The following sections describe policy maps and QoS actions:
• Feature History for QoS Policies, page 3-2
• Defining QoS Actions Using a Policy Map, page 3-2
• System Limits for Policy Maps, page 3-2
• 8K Policy Maps, page 3-3
• policy-map Command, page 3-3
