Mapping QoS Labels to Queues and Drop Thresholds

These sections describe how to map QoS labels to queues and drop thresholds:
Enter the show queueing interface {ethernet | fastethernet | gigabitethernet | tengigabitethernet}
Note
slot/port | include type command to see the queue structure of a port.

Configuring CoS-Based Queue Mapping, page 38-85
When SRR is enabled, you cannot map any CoS values or DSCP values to strict-priority queues.
Queue number 1 is the lowest-priority standard queue.
Higher-numbered queues are higher priority standard queues.
You can map up to 8 CoS values to a threshold.
You can map up to 64 DSCP values to a threshold.
Threshold 0 is a nonconfigurable 100-percent tail-drop threshold on these port types:
1p1q0t (receive)
–
1p1q8t (receive)
–
1p3q1t (transmit)
–
– 1p2q1t (transmit)
The standard queue thresholds can be configured as either tail-drop or WRED-drop thresholds on
these port types:
1p1q8t (receive)
–
– 1p3q1t (transmit)
– 1p3q8t (transmit)
– 1p7q1t (transmit)
