Schedulin
g Method

Select Strict Priority or Weighted Round Robin.

Strict Priority scheduling singles out the highest priority queue and ensures 
all queued traffic in this queue is transmitted before servicing the lower 
priority queues. Strict Priority scheduling services the remaining queues 
using WRR. 

Note: Queue weights can only be changed when Weighted Round 

Robin is selected. 

Weighted Round Robin scheduling services queues on a rotating basis 
based on their queue weight (the number you configure in the queue Weight 
field). Queues with larger weights get more service than queues with smaller 
weights.
