Configuring PFC QoS

Mapping QoS Labels to Queues and Drop Thresholds

These sections describe how to map QoS labels to queues and drop thresholds:

Note Enter the show queueing interface {ethernet fastethernet gigabitethernet tengigabitethernet} slot/port include type command to see the queue structure of a port.

Queue and Drop Threshold Mapping Guidelines and Restrictions

When mapping QoS labels to queues and thresholds, note the following information:

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)

Configuring DSCP-Based Queue Mapping

These sections describe how to configure DSCP-based queue mapping:

Mapping DSCP Values to Standard Transmit-Queue Thresholds, page 42-102

Mapping DSCP Values to the Transmit Strict-Priority Queue, page 42-103

Note DSCP-based queue mapping is supported on WS-X6708-10GE ports.
