Configuring PFC QoS
To configure the drop thresholds, perform this task:
Command
Step 1
Router(config)# interface {fastethernet |
gigabitethernet} slot/port
Step 2
Router(config-if)# rcv-queue threshold queue_id
thr1% thr2% thr3% thr4% {thr5% thr6% thr7% thr8%}
Router(config-if)# no rcv-queue threshold
[queue_id]
Step 3
Router(config-if)# end
Step 4
Router# show queueing interface {fastethernet |
gigabitethernet} slot/port
This example shows how to configure the receive-queue 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)# rcv-queue threshold 1 60 75 85 100
Router(config-if)# end
Router#
This example shows how to verify the configuration:
Router# show queueing interface gigabitethernet 1/1 | begin Receive queues
Receive queues [type = 1p1q4t]:
Trust state: trust COS

Configuring a WRED-Drop Transmit Queue
These port types have only WRED-drop thresholds in their transmit queues:
•
•
To configure the drop thresholds, perform this task:
Command
Step 1
Router(config)# interface type
Step 2
Router(config-if)# wrr-queue random-detect
min-threshold queue_id thr1% [thr2%]
Router(config-if)# no wrr-queue random-detect
min-threshold [queue_id]
