Configuring Uniform Mode
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:
Note The bandwidth command and random-detect command are not supported on LAN ports.
Command Purpose
Step 1
Router(config)# mls qos
Enables QoS functionality.
Step 2
Router(config)# class-map class_name
Specifies the class map to which packets will be mapped
(matched). Creates a traffic class.
Step 3
Router(config-c-map)# match mpls experimental
exp_list
Specifies the MPLS EXP field values used as a match
criteria against which packets are checked to determine if
they belong to the class.
Step 4
Router(config)# policy-map name
Configures the QoS policy for packets that match the class
or classes.
Step 5
Router(config-p-map)# class class_name
Associates the traffic class with the service policy.
Step 6
Router(config-p-map-c)# bandwidth
{
bandwidth_kbps | percent percent }
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.
Step 7
Router(config-p-map)# class class-default
Specifies the default class so that you can configure or
modify its policy.
Step 8
Router(config-p-map-c)# random-detect
Enables a WRED drop policy for a traffic class that has a
bandwidth guarantee.
Step 9
Router(config)# interface type slot/port
Selects an interface to configure.
Step 10
Router(config-if)# service-policy output name
Attaches a QoS policy to an interface and specifies that
policies should be applied on packets leaving the interface.
