Chapter 3 Cisco CRS-3 Carrier Routing System Router Command Changes
Within a policy map, you can give one or more classes priority status. When multiple classes within a
single policy map are configured as priority classes, all traffic from these classes at same priority level
is queued to the same, single priority queue. There is one priority queue per level in a group.
Modifying CRS-MSC-40G QoS Configurations for CRS-MSC-140G
On the Cisco CRS Series Modular Services Card 40G (CRS-MSC-40G), a priority action can be
configured with or without a police action in the same class.
On the Cisco CRS Series Modular Services Card 140G (CRS-MSC-140G), a police action must be
configured in the same class as the priority action. A class configuration that includes a priority action
but no police action is not valid. Such a configuration is rejected.
To use existing CRS-MSC-40G QoS configurations on the CRS-MSC-140G, add a police action to all
classes that have a priority action.
Priority assignment at the group level for an egress interface policy is not supported.

Examples The following example shows how to configure priority queuing for the policy map named policy1:
RP/0/RP0/CPU0:router(config)# policy-map policy1
RP/0/RP0/CPU0:router(config-pmap)# class class1
RP/0/RP0/CPU0:router(config-pmap-c)# priority level 1
RP/0/RP0/CPU0:router(config-pmap-c)# police rate percent 20
RP/0/RP0/CPU0:router(config-pmap-c)# class class-default
RP/0/RP0/CPU0:router(config-pmap-c)# end-policy-map
