Hallo @pigallo,   thanks for your response.  I agree, there is not much documentation available for this situation.   I am not sure if I simply don't fully grasp your response or if there is a misunderstanding, so please let me clarify what I am asking.    policy-map PARENT class class default shape average 60 service-policy CHILD policy-map CHILD  class EF   priority percent 10  class AF bandwidth percent 50 class class-default   random-detect dscp-based  bandwidth percent 40 interface TenGigabitEthernet0/1/0 service-policy output PARENT So far I believe I understand what's happening: I have a given bandwidth, e.g. 10G and this is being shaped down to 6G with a prio queue and different minimum bandwidth reservations.   Now I add the subinterface  TenGigabitEthernet0/1/0.100 without adding any additional service policy. Is the traffic that passes this subinterface shaped to 5G and is the subsequent child policy applied to the subinterface traffic as well? If not, is any traffic passing the subinterface accounted for in the main service policy or could we theoretically see 6G traffic on main interface plus 4G on the sub interface? Is the prio queue for the main interface taking precedence over the subinterface in case of contention?     Regards       ... View more

Hi  Remi Astruc,   thank you, somehow I missed that option. It's a pitty though that I have to remove the virtual domain and reapply it to change these settings. Anyway, it is the option I was looking for.     Best regards     ... View more
