    Hello Xinhui,

     

    MPC-3D-16XGE-SFPP doesn't support hierarchical CoS, because it doesn't have a queueing chip. For example:

    "Hierarchical CoS queuing features are supported on interfaces hosted on MICs in MPC1 Q, MPC2 Q, MPC2 EQ, MPC5EQ, MPC7E, MPC8E, and MPC9E line cards" as per Per-Unit Queuing and Hierarchical Queuing for MIC and MPC Interfaces

    16x10GE MPC is also listed in Scaling of Per-VLAN Queuing on Non-Queuing MPCs

     

    Best regards,

    Sergii
