Configuring PFC QoS
• 1p7q8t (transmit)
To configure the drop thresholds, perform this task:
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. End with CNTL/Z.
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]:
Queue Id Scheduling Num of thresholds
-----------------------------------------
1 WRR low 2
2 WRR high 2
3 Priority 1
queue random-detect-max-thresholds
----------------------------------
1 40[1] 70[2]
2 40[1] 70[2]

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