-
Strict Priority—Traffic scheduling for the selected queue and all higher
queues is based strictly on the queue priority.
-
WRR—Traffic scheduling for the selected queue is based on WRR. The
period time is divided between the WRR queues that are not empty,
meaning they have descriptors to egress. This happens only if strict
priority queues are empty.

queue.
-
% of WRR Bandwidth—Displays the amount of bandwidth assigned to
the queue. These values represent the percent of the WRR weight.
