Setting the Priority of Packets with the EXP

Ethernet over MPLS provides QoS using the three EXP bits in a label to determine the priority of
packets. To support QoS between ML-Series card point-to-point endpoints, set the experimental bits in
both the VC and tunnel labels.
Perform the following steps to set the experimental bits:
Command
Step 1
Router(config)# class-map
class-name
Step 2
Router(config-cmap)# match
any
Step 3
Router(config-cmap)#end
Step 4
Router(config)# policy-map
policy-name
Step 5
Router(config-pmap)# class
class-name
Step 6
Router (config-pmap-c)# set

Step 7

Cisco ONS 15454 and Cisco ONS 15454 SDH Ethernet Card Software Feature and Configuration Guide, R8.0
Purpose
Enters SPR subinterface configuration mode for
the ML-Series card.
Assigns the network interface to a bridge group.
Returns to privileged EXEC mode.
(Optional) Saves your entries in the configuration
file.
Purpose
Specifies the user-defined name of the traffic class.
Specifies that all packets will be matched.
Returns to global configuration mode.
Specifies the name of the traffic policy to configure.
Specifies the name of a predefined traffic class, which was
configured with the class-map command, used to classify traffic
to the traffic policy.
Designates the value to which the MPLS bits are set if the packets
match the specified policy map.
Enters interface configuration mode.
Attaches a traffic policy to an interface.
