QoS on Bundle Ether Cisco NCS XR Platform

[Shahrier]

Hi ,

I am trying to configure QoS on Bundle Ether, but after configure QoS on bundle Ether getting below error: 

interface Bundle-Ether10
l2transport
service-policy output 15_Gbps
!!% 'qos-lib' detected the 'warning' condition 'MQC: Shape bandwidth rate is greater than the parent reference bandwidth'
 !
!

Conf Details:

policy-map 15_Gbps
class class-default
shape average 15360 mbps
!

interface Bundle-Ether10
mtu 9216
l2transport

 service-policy output 15_Gbps

As per cisco The QoS policy that is applied on bundle is inherited to all its member links and the reference bandwidth that is used to calculate shaper/bandwidth is applied as per the physical member interface bandwidth, and not the bundle as a whole.

So can anyone please suggest me how i can configure QoS in Bundle Ether.

Thanks in advance.

Regards,

Shahrier

the shaper cannot be more than a single link in the bundle, please check

-Based on your description you are hitting below limitation:

  *   The shape rate that is specified in the bundle policy-map is not an aggregate for all bundle members. The shape rate applied to the bundle depends on the load balancing of the links. For example, if a policy map with a shape rate of 10 Mbps is applied to a bundle with two member links, and if the traffic is always load-balanced to the same member link, then an overall rate of 10 Mbps applies to the bundle. However, if the traffic is load-balanced evenly between the two links, the overall shape rate for the bundle becomes 20 Mbps.

Thank you for your replay. Could you please also suggest how can i shape ingress traffic, configured below but getting error:

policy-map 15_Gbps
class class-default
shape average 15 gbps
!
end-policy-map
!

interface Bundle-Ether15.2005 l2transport
encapsulation dot1q 11
mtu 9216
service-policy intput 15_Gbps

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

Thanks in advance.

shape only supports on egress direction.

Ingress side, you can use the police.
