Command Purpose
Step 1
Router(config)# mpls cos-map cos-map
number
Creates a class of service (CoS) map that specifies how classes
map to label virtual circuits (LVCs) when they are combined with
a prefix map. Enters cos-map configuration submode.
Step 2
Router(config-tag-cos-map)# class class
[available | standard | premium |control]
Maps traffic classes to LVCs.
class is the precedence of identified traffic to classify traffic.
The default values for assigning traffic classes to the CoS map
range from 0 to 3:
Class 0—Available
Class 1—Standard
Class 2—Premium
Class 3—Control
The two least significant bits of the EXP field in the packet header
determine the class of a packet.
Step 3
Router(config-tag-cos-map)# exit
Exits the cos-map configuration submode.
Step 4
Router(config)# access-list
access-list-number permit destination
Creates an access list to control traffic going to the specified
destination address.
Step 5
Router(config)# mpls prefix-map
prefix-map access-list access-list
cos-map cos-map
Configures the router to use a specified QoS map when an MPLS
destination prefix matches the specified access list.
