Hej
I am working on a QoS profile for MPLS Customers. where I limit overall port traffic with a Parent policy, then use Child policy to limit some of the DSCP values on ingress.
For example: I limit Overall interface ingress BW to 100Mbps, and limit EF traffic to only 10% of that.
My issue is that I can not figure out how to guarantee the 10% EF traffic on ingress.
I see that if for example I send 1G BE traffic, I only see maybe 1% EF traffic or even less being passed. So there doesn't seem to be a filtering or buffering mechanism on ingress. Or none that I could find.
I would appreciate the help. Below is the config
###########PARENT POLICY########### policy-map INGRESS-PARENT-100M class class-default service-policy INGRESS-CHILD police rate 100 mbps ! ! end-policy-map ! ###########CHILD POLICY########### policy-map PM-ACCESS-IN-CHILD description STANDARD QoS child for CPE access with QoS class CM-ACCESS-IN-EF set traffic-class 5 set mpls experimental imposition 5 police rate percent 10 ! ! class class-default set traffic-class 1 set mpls experimental imposition 1 ! end-policy-map ! ################CLASS-MAP############ class-map match-any CM-ACCESS-IN-EF match dscp ef end-class-map !

Hi Odj ,
Please suggest the plaftorm you want to apply this config , as QOS is H.W specefic in all XR platforms and there can be limiation on specefic platfoms.

Hej ntikader
We are using NCS55A2 version 7.2.2

Hi Odj ,
Regarding the QoS config suggested is either incomplete or wrong config .
Also when using Parent Child polices it means you want to use hierarchical qos policy .
To enable HQoS on NCS5500 you need the below global configuration command
“hw-module profile qos hqos-enable” ------ thsi require router reload
policy-map INGRESS-PARENT-100M class class-default service-policy INGRESS-CHILD where is this policy configured . police rate 100 mbps ! ! end-policy-map
Please check the below cco link for Do and Dont during QOS config in NCS platforms.
