I. Configuring custom-list according to MPLS EXP
Configure custom-list according to MPLS EXP and enable packets to enter different
queues.
Perform the following configurations in system view.

For PQ configurations, refer back to the subsection "CQ (Custom Queuing)" in the
section "Congestion Management Policies".
II. Applying custom-list on the Interface
Perform the following configuration in interface view.

Not CQ but FIFO is employed on the interface by default.

6.2.3 Configuring MPLS CBQ

Complete these four steps to configure MPLS CBQ: First, define CBQ classes and
configure matching rule according to the MPLS EXP. Second, define traffic behaviors
and configure processing scheme of MPLS EXP domain. Third, define a QoS policy
and specify specific traffic behavior for CBQ classes. Forth, apply QoS policy on the
interface. For more information, refer to PQ Configuration in Congestion Management.
I. Defining/deleting exp domain rule of packets matching MPLS
MPLS QoS allows users to set MPLS EXP domain on PE to classify MPLS packets and
make them enter different queues to implement QoS. In this case, IP packets can travel
through MPLS network transparently without change.
Firstly you should define a CBQ class with a certain class name, and then enter this
class view to configure the classification regulation by EXP value in MPLS label field.
Perform the following configurations in system view.
