Cisco CRS Command Reference Guide

experimental value of 2 should be treated differently than a packet marked with the EXP value of 1. The
treatment of these different packets is defined by the user through the setting of QoS policies in policy map
class configuration mode.

Examples
The following example shows how to configure the service policy called policy1 and attach service policy
policy1 to an interface. In this example, class map mplsmap1 evaluates all packets entering GigabitEthernet
interface 0/1/0/9 for an MPLS experimental value of 1. If the incoming packet has been marked with the
MPLS experimental value of 1, the packet is queued to the class queue with the bandwidth setting of 300
kbps.
RP/0/RP0/CPU0:router(config)# class-map mplsmap1
RP/0/RP0/CPU0:router(config-cmap)# match mpls experimental topmost 1
RP/0/RP0/CPU0:router(config-cmap)# exit
RP/0/RP0/CPU0:router(config)# policy-map policy1
RP/0/RP0/CPU0:router(config-pmap)# class mplsmap1
RP/0/RP0/CPU0:router(config-pmap-c)# bandwidth 300
RP/0/RP0/CPU0:router(config-pmap-c)# exit
RP/0/RP0/CPU0:router(config-pmap)# exit
RP/0/RP0/CPU0:router(config)# interface gigabitethernet 0/1/0/9
RP/0/RP0/CPU0:router(config-if)# service-policy input output policy1
