QoS on NCS

BB7
Beginner
Beginner

Hello Experts,

 

I am trying to configure QoS on NCS router using the reference guide. It's a simple configuration with one class-map having one match condition and one policy-map.

 

RP/0/RP0/CPU0:router# configure
RP/0/RP0/CPU0:router(config)# class-map ipprec5
RP/0/RP0/CPU0:router(config-cmap)# match precedence ipv4 5	
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 ipprec5
RP/0/RP0/CPU0:router(config-pmap-c)# bandwidth 1000 mbps
RP/0/RP0/CPU0:router(config-pmap)# exit

RP/0/RP0/CPU0:router(config)# interface HundredGigabitEthernet  0/1/0/9
RP/0/RP0/CPU0:router(config-if)# service-policy input policy1

According to the link: https://www.cisco.com/c/en/us/td/docs/iosxr/ncs5500/qos/b-ncs5500-qos-cli-reference/b-ncs5500-qos-cli-reference_chapter_01.html#wp1772137353, the ip precedence match condition is supported in ingress direction. But after commiting the above config I am getting the following errors

 

service-policy input policy5

!!% 'DNX_QOSEA' detected the 'warning' condition 'Unsupported action type for ingress.

 

Any help would be appreciated?

 

Thanks.

I'm unfamiliar with the NCS, but in general, you cannot have a class bandwidth statement within an ingress policy.

Hi all

 

I have the same problem and till now, I dont find the solution, let me explain the situation.

We have N540-24Z8Q2C-Mand ASR 920 into our Carrier Ethernet Network, we provide, E-line over EVC to customers for instance to interconnect their branch offices, and we need to shape traffic in egress to commited rate, this is working on ASR 920, but on NCS 540 I get below message 

!!% 'DNX_QOSEA' detected the 'warning' condition 'Unsupported match type for egress.'

 

Find below my configuration, thank you for your suggestions

Best regards

As it appears you're matching all CoS, have your tried any other matching, like all IP Prec or just use the class-default with the shaper there?
