Configuring PFC3BXL or PFC3B Mode MPLS QoS
Configuring the Egress PE Router—Customer Facing Interface
QoS features shown here are available only with OSM and FlexWAN and Enhanced FlexWAN modules.
Note
To classify a packet based on its IP DSCP value 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 ip dscp dscp_values
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
dscp-based
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 a packet based on its IP DSCP value and provide appropriate discard
and scheduling treatments:
Router(config)# mls qos
Router(config)# class-map IP-PREC-4
Router(config-c-map)# match ip precedence 4
Router(config)# policy-map output-qos
Router(config-p-map)# class IP-PREC-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 GE-WAN 3/2.32
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.
Uses the DSCP values as the match criteria.
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.
