Chapter 39 Configuring MPLS QoS

Configuring Uniform Mode

This section describes how to configure the following:
•
•
•
The steps that follow show one way, but not the only way, to configure the Uniform mode.
Note
Configuring the Ingress PE Router—Customer Facing Interface
For Uniform mode, setting the trust state to IP precedence or IP DSCP allows the PFC3B to copy the IP
PHB into the MPLS PHB.
This description applies to PFC QoS for LAN or OSM ports. For information about FlexWAN and

To configure a policy map to set the MPLS EXP field in imposed label entries, perform this task:

Step 3
Router(config)# class-map class_name
Step 4
Router(config-cmap)# match access-group
ipv4_acl_number_or_name
Step 5
Router(config)# policy-map policy_map_name
Step 6
Router(config-pmap)# class class_name

Purpose
Enables PFC QoS globally.
Creates an IPv4 access list.
Creates a class map.
Configures the class map to filter with the ACL created in
Step 2.
Creates a named QoS policy.
Configures the policy to use the class map created in step 3.
Configures policing, including the following:
• Action to take on packets that conform to the rate limit
specified in the SLA.
• Action to take on packets that exceed the rate limit
specified in the SLA.
Selects an interface to configure.
Configures received DSCP as the basis of the internal DSCP
for all the port's ingress traffic.
Attaches the policy map created in step
an input service policy.
