Cisco Nexus 7000 Series NX-OS Security Configuration Guide 8. So, any packets that are within the 128000 CIR limit plus the 4000 BC limit are conforming. Committed information rate, or desired bandwidth, specified as a bit rate or a percentage of the link rate. Let’s take another example: policy-map TEST. target shape rate 5000000 .

Cisco Nexus 9000 Series NX-OS Quality of Service Configuration Guide, Release 9. For example if my CIR is 64000 I have 'had' a situation where I have a class configured with bandwidth remaining percent and a policer. The Cisco IOS traffic policing software features allow you to control the maximum rate of traffic sent or received on an interface. Starting with Cisco NX-OS Release Policing and Shaping are QoS techniques used to manage and control bandwidth usage. we can only use police too without CIR keyword. 99 MB) PDF - - I want to do two rate policing on my PE for client. class class-default.
