Configuring PFC QoS
To configure the drop thresholds, perform this task:
Command
Step 1
Router(config)# interface type
Step 2
Router(config-if)# wrr-queue threshold queue_id
thr1% [thr2% thr3% thr4% thr5% thr6% thr7% thr8%]
Router(config-if)# no wrr-queue threshold
[queue_id]
Step 3
Router(config-if)# wrr-queue random-detect
min-threshold queue_id thr1% [thr2% thr3% thr4%
thr5% thr6% thr7% thr8%]
Router(config-if)# no wrr-queue random-detect
min-threshold [queue_id]
Step 4
Router(config-if)# wrr-queue random-detect
max-threshold queue_id thr1% [thr2% thr3% thr4%
thr5% thr6% thr7% thr8%]
Router(config-if)# no wrr-queue random-detect
max-threshold [queue_id]
Step 5
Router(config-if)# wrr-queue random-detect
queue_id
Router(config-if)# no wrr-queue random-detect
[queue_id]
Step 6
Router(config-if)# end
Step 7
Router# show queueing interface type
1. type = fastethernet, gigabitethernet, or tengigabitethernet
This example shows how to configure the low-priority transmit queue high-WRED-drop thresholds for
Gigabit Ethernet port 1/1:
Router# configure terminal
Enter configuration commands, one per line.
Router(config)# interface gigabitethernet 1/1
Router(config-if)# wrr-queue random-detect max-threshold 1 70 70
Router(config-if)# end
Router#
This example shows how to verify the configuration:
Router# show queueing interface gigabitethernet 1/1 | begin Transmit queues
Transmit queues [type = 1p2q2t]:

Purpose
Selects the interface to configure.
Configures the tail-drop thresholds.
Reverts to the default tail-drop thresholds.
Configures the low WRED-drop thresholds.
Reverts to the default low WRED-drop thresholds.
Configures the high WRED-drop thresholds.
Reverts to the default high WRED-drop thresholds.
Enables WRED-drop thresholds.
Enables tail-drop thresholds.
Exits configuration mode.
Verifies the configuration.
End with CNTL/Z.
