Command History
Release
Release 6.0
Policer conditional set is unsupported.
Usage Guidelines
Policing can be applied only in the ingress direction.
For police rate commands, interpret the percent keyword in this way:
• For a one-level policy, the percent keyword specifies the CIR as a percentage of the link rate. For
Note
Configured values take into account the Layer 2 encapsulation applied to traffic. This applies to ingress
policing. For Ethernet transmission, the encapsulation is considered to be 14 bytes, whereas for IEEE 802.1Q,
the encapsulation is 18 bytes.
For more information, see the Committed Bursts and Excess Bursts section in the Modular QoS Configuration
Guide for Cisco NCS 5500 Series Routers.
Note
A police rate minimum of 21 kbps is supported.

In this example for MPLS, traffic policing is configured with the average rate at 250 kbps, and the
normal burst size at 50 bytes for all packets leaving HundredGigE interface 0/1/0/0:
RP/0/RP0/CPU0:router(config)# class-map class1
RP/0/RP0/CPU0:router(config-cmap)# match mpls experimental topmost 0
RP/0/RP0/CPU0:router(config-cmap)# exit

RP/0/RP0/CPU0:router(config-pmap)# class class1
RP/0/RP0/CPU0:router(config-pmap-c)# police rate 250 kbps burst 50
RP/0/RP0/CPU0:router(config-pmap-c)# exit
