Configuring PFC3BXL or PFC3B Mode MPLS QoS
Configuration Example
This example shows how to configure a policy map to set the MPLS EXP field in imposed label entries:
Router(config)# mls qos
Router(config)# access-list 1 permit any
Router(config)# class-map CUSTOMER-A
Router(config-cmap)# match access-group 1
Router(config)# policy-map SLA-A
Router(config-pmap)# class CUSTOMER-A
Router(config-pmap-c)# police 50000000 conform-action transmit exceed-action drop
Router(config)# interface GE-WAN 3/1
Router(config-if)# mls qos trust dscp
Router(config)# interface GE-WAN 3/1.31
Router(config-if)# service-policy input SLA-A
Configuring the Ingress PE Router—P Facing Interface
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
Note
The bandwidth command and random-detect command are not supported on LAN ports.
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.
