Configuring PFC QoS

To configure the drop thresholds, perform this task:

	Command	Purpose
Step 1
Step 1	Router(config)# interface type1 slot/port	Selects the interface to configure.
Step 2
Step 2	Router(config-if)#rcv-queue threshold queue_id	Configures the tail-drop thresholds.
	thr1% thr2% thr3% thr4% thr5% thr6% thr7% thr8%
	Router(config-if)#no rcv-queue threshold	Reverts to the default tail-drop thresholds.
	[queue_id]
Step 3
Step 3	Router(config-if)#rcv-queue random-detect	Configures the low WRED-drop thresholds.
	min-thresholdqueue_id thr1% thr2% thr3% thr4%
	thr5% thr6% thr7% thr8%
	Router(config-if)#no rcv-queue random-detect	Reverts to the default low WRED-drop thresholds.
	min-threshold [queue_id]
Step 4
Step 4	Router(config-if)#rcv-queue random-detect	Configures the high WRED-drop thresholds.
	max-thresholdqueue_id thr1% thr2% thr3% thr4%
	thr5% thr6% thr7% thr8%
	Router(config-if)#no rcv-queue random-detect	Reverts to the default high WRED-drop thresholds.
	max-threshold [queue_id]
Step 5
Step 5	Router(config-if)#rcv-queue random-detect	Enables WRED-drop thresholds.
	queue_id
	Router(config-if)#no rcv-queue random-detect	Enables tail-drop thresholds.
	[queue_id]
Step 6
Step 6	Router(config-if)# end	Exits configuration mode.
Step 7
Step 7	Router# show queueing interface type1 slot/port	Verifies the configuration.

Configuring a WRED-Drop and Tail-Drop Transmit Queue

These port types have both WRED-drop and tail-drop thresholds in their transmit queues:

•1p3q1t (transmit)

•1p3q8t (transmit)

•1p7q8t (transmit)

To configure the drop thresholds, perform this task:

	Command	Purpose
Step 1
Step 1	Router(config)# interface type1 slot/port	Selects the interface to configure.
Step 2
Step 2	Router(config-if)#wrr-queue threshold queue_id	Configures the tail-drop thresholds.
	thr1% [thr2% thr3% thr4% thr5% thr6% thr7% thr8%]
	Router(config-if)#no wrr-queue threshold	Reverts to the default tail-drop thresholds.
	[queue_id]
Step 3
Step 3	Router(config-if)#wrr-queue random-detect	Configures the low WRED-drop thresholds.
	min-thresholdqueue_id thr1% [thr2% thr3% thr4%
	thr5% thr6% thr7% thr8%]
	Router(config-if)#no wrr-queue random-detect	Reverts to the default low WRED-drop thresholds.
	min-threshold [queue_id]
