Chapter 42 Configuring PFC3BXL or PFC3B Mode MPLS QoS
QoS features shown here are available only with OSM and FlexWAN and Enhanced FlexWAN modules.
Note
To classify packets based on their MPLS EXP field and provide appropriate discard and scheduling
treatments, perform this task:
Command
Step 1
Router(config)# mls qos
Step 2
Router(config)# class-map class_name
Step 3
Router(config-c-map)# match mpls experimental
exp_list
Step 4
Router(config)# policy-map name
Step 5
Router(config-p-map)# class class_name
Step 6
Router(config-p-map-c)# bandwidth
{ bandwidth_kbps | percent percent }
Step 7
Router(config-p-map)# class class-default
Step 8
Router(config-p-map-c)# random-detect
Step 9
Router(config)# interface type slot/port
Step 10
Router(config-if)# service-policy output name
The bandwidth command and random-detect command are not supported on LAN ports.
Note

Configuration Example

This example shows how to classify packets based on their MPLS EXP field and provide appropriate
discard and scheduling treatments:
Router(config)# mls qos
Router(config)# class-map MPLS-EXP-4
Router(config-c-map)# match mpls experimental 4
Router(config)# policy-map output-qos
Router(config-p-map)# class MPLS-EXP-4
Router(config-p-map-c)# bandwidth percent 40
Router(config-p-map)# class class-default
Router(config-p-map-c)# random-detect
Router(config)# interface pos 4/1
Router(config-if)# service-policy output output-qos
OL-4266-08
Purpose
Enables QoS functionality.
Specifies the class map to which packets will be mapped
(matched). Creates a traffic class.
Specifies the MPLS EXP field values used as a match
criteria against which packets are checked to determine if
they belong to the class.
Configures the QoS policy for packets that match the class
or classes.
Associates the traffic class with the service policy.
Specifies the minimum bandwidth guarantee to a traffic
class. You can specify the minimum bandwidth guarantee in
kilobits per second or by percent of the overall bandwidth.
Specifies the default class so that you can configure or
modify its policy.
Enables a WRED drop policy for a traffic class that has a
bandwidth guarantee.
Selects an interface to configure.
Attaches a QoS policy to an interface and specifies that
policies should be applied on packets leaving the interface.
