Chapter 1 Configuring a Service Policy Using the Modular Policy Framework
Identifying Traffic (Layer 3/4 Class Maps)
Step 2 Create a policy map according to the “Defining Actions (Layer 3/4 Policy Map)” section on page 1-15,
and identify the sole action for each class map as priority.
Step 3 Create a separate policy map according to the “Defining Actions (Layer 3/4 Policy Map)” section on
page 1-15, and identify the shape action for the class-default class map.
Traffic shaping can only be applied the to class-default class map.
Step 4 For the same class map, identify the priority policy map that you created in Step 2 using the
service-policy priority_policy_map command.
Step 5 Apply the shaping policy map to the interface accrding to “Applying Actions to an Interface (Service
Policy)” section on page 1-17.
Identifying Traffic (Layer 3/4 Class Maps)
A Layer 3/4 class map identifies Layer 3 and 4 traffic to which you want to apply actions. You can create
multiple Layer 3/4 class maps for each Layer 3/4 policy map.
This section includes the following topics:
• Creating a Layer 3/4 Class Map for Through Traffic, page 1-12
• Creating a Layer 3/4 Class Map for Management Traffic, page 1-15
Creating a Layer 3/4 Class Map for Through Traffic
A Layer 3/4 class map matches traffic based on protocols, ports, IP addresses and other Layer 3 or 4
attributes.
Detailed Steps
Command Purpose
Step 1
class-map class_map_name
Example:
hostname(config)# class-map all_udp
Creates a Layer 3/4 class map, where class_map_name is a string
up to 40 characters in length. The name “class-default” is
reserved. All types of class maps use the same name space, so you
cannot reuse a name already used by another type of class map.
The CLI enters class-map configuration mode.
Step 2
(Optional)
description string
Example:
hostname(config-cmap)# description All UDP
traffic
Adds a description to the class map.
Step 3
Match traffic using one of the following: Unless otherwise specified, you can include only one match
command in the class map.
