–
One standard queue with no configurable threshold (effectively a tail-drop threshold at
100 percent).
•
1p1q8t
indicates the following:
–
One strict-priority queue
–
One standard queue with these thresholds:
—Eight thresholds, each configurable as either WRED-drop or tail-drop
—One non configurable (100 percent) tail-drop threshold
