QoS Configured but exceed configured shape

[Shahrier]

Hi,

I have been configured QoS BW shaping purpose but exceeding my configured BW shape. My configured BW is 10G but it exceed 11.35G. Here attached my graph as well as configuration. Can anyone please help me this issue.

policy-map 10_Gbps
class class-default
shape average 10 gbps
!
end-policy-map
!

!
interface Bundle-Ether15
mtu 9216
l2transport
service-policy output 10_Gbps
!
!

Thanks in advance.

Regards,

in certain situations bundle can exceed if spread across multiple NPUs

please see

Link bundle members may appear across multiple Network Processing Units and linecards. The shape rate specified in the bundle policymap is not an aggregate for all bundle members. The shape rate applied to the bundle will depend 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 will apply to the bundle. However, if the traffic is load-balanced evenly between the two links, the overall shape rate for the bundle will be 20 Mbps.
