MPLS Traffic Engineering—DiffServ Aware
Monitoring and Maintaining MPLS CoS Multi-VC Mode Configuration
To monitor and maintain the configuration of MPLS CoS Multi-VC Mode on ATM interfaces, enter any
of the following commands in privileged EXEC mode:
Command
Router# show mpls interfaces [interface] [detail]
Router# show mpls cos-map [cos-map]
Router# show mpls prefix-map [prefix-map]
Router# debug mpls atm-cos [bind | request]
Configuration Examples for MPLS CoS Multi-VC Mode

MPLS Traffic Engineering—DiffServ Aware
The MPLS Traffic Engineering—DiffServ Aware (DS-TE) feature extends MPLS traffic engineering
capabilities to provide stricter quality of service (QoS) guarantees. TE tunnels provide differentiated
services (DiffServ) to satisfy bandwidth requirements of regular traffic. However, the bandwidth
currently advertised for TE tunnels and the tunnel traffic does not correspond to any queue. Instead, the
MPLS class of service (CoS) provides DiffServ service, which is adequate for most customer services.
Special services such as voice, however, require stricter QoS guarantees. The DS-TE feature addresses
this need, providing strict bandwidth guarantees for TE tunnels.
The DS-TE feature introduces awareness of a particular class of traffic referred to as the guaranteed
bandwidth traffic. DS-TE enables you, as service providers, to perform separate admission control and
separate route computation of the guaranteed bandwidth traffic. Therefore, you can develop QoS
services for end customers that rely on signaled QoS rather than provisioned QoS, which enables you to
build QoS services with hard commitments and without overprovisioning.

Purpose
Displays information about one or more interfaces that have been
configured for label switching.
If you do not specify an interface, information about all interfaces
that have been configured for label switching displays.
detail displays detailed label switching information for the
specified interface or for all interfaces if you do not specify an
interface.
Displays the quality of service (QoS) map used to assign a
quantity of label virtual circuits and the associated class of
service (CoS) for those virtual circuits.
cos-map is an optional number that specifies the QoS map to be
displayed.
Displays the prefix map used to assign a QoS map to network
prefixes that match a standard IP access list.
prefix-map is an optional number that specifies the prefix map to
be displayed.
Displays ATM label VC bind or request activity that is based on
the configuration of a QoS map.
