Question

Are fine-grained queuing capabilities supported on Enhanced Queuing DPCs (DPCE-R-Q)?

Answer

Yes. DPCE-Rs and DPCE-Qs support up to 64,000 individual queues across both 1-Gigabit Ethernet and 10-Gigabit Ethernet ports. Additional features supported on these DPC types include:

 

  • Four-level hierarchical WRR
  • Four levels of per-VLAN queue priority
  • Priority propagation
  • Drop statistics per VLAN, color, or queue
  • Changeable allocation of schedulers per port for up to 8,000 scheduler nodes with eight queues each or 16,000 nodes with four queues each
