Configuring The Egress Pe Router—Customer Facing Interface - Cisco WS-SUP32-GE-3B - Supervisor Engine 32 Software Configuration Manual

Chapter 39 Configuring MPLS QoS
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-3
Router(config-c-map)# match mpls experimental 3
Router(config)# policy-map output-qos
Router(config-p-map)# class MPLS-EXP-3
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
Configuring the Egress PE Router—Customer Facing Interface
To configure the egress PE router at the customer-facing interface, 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 precedence
precedence-value
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) mpls propagate-cos
Step 11
Router(config-if)# service-policy output name
Note The bandwidth command and random-detect command are not supported on LAN ports.
OL-11439-03
Purpose
Enables PFC QoS globally.
Specifies the class map to which packets will be mapped
(matched). Creates a traffic class.
Identifies IP precedence values as 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.
Applies WRED to the policy based on the IP precedence or
the MPLS EXP field value.
Selects an interface to configure.
Enables propagation of EXP value into the underlying IP
DSCP at the MPLS domain exit LER egress port.
Attaches a QoS policy to an interface and specifies that
policies should be applied on packets coming into the
interface.
