You can enable flexible queuing on non-HQoS MPCs, such as the MPC2E-3D-NG and MPC3E-3D-NG. When flexible queuing is enabled, non-HQoS MPCs support a limited queuing capability of 32,000 queues per slot, including ingress and egress.
You can enable flexible queuing by including the flexible-queuing-mode statement at the [edit chassis fpc] hierarchy level. When flexible queuing is enabled, the MPC is restarted and is brought online only if the power required for the queuing component is available in the PEM. The MPC remains offline if the PEM cannot meet the power requirement for the queuing component.
The following MICs are supported on non-HQoS MPCs only when flexible queuing is enabled:
