Configuring PFC QoS
Command
Step 3
Router(config-if)# wrr-queue random-detect
max-threshold queue_id thr1% [ thr2% ]
Router(config-if)# no wrr-queue random-detect
max-threshold [ queue_id ]
Step 4
Router(config-if)# end
Step 5
Router# show queueing interface type
1. type = fastethernet, gigabitethernet, or tengigabitethernet
Configuring a WRED-Drop and Tail-Drop Receive Queue
These port types have both WRED-drop and tail-drop thresholds in their receive queues:
•
•
•
To configure the drop thresholds, perform this task:
Command
Step 1
Router(config)# interface type
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)# rcv-queue random-detect
min-threshold queue_id thr1% thr2% thr3% thr4%
thr5% thr6% thr7% thr8%
Router(config-if)# no rcv-queue random-detect
min-threshold [ queue_id ]
Step 4
Router(config-if)# rcv-queue random-detect
max-threshold queue_id thr1% thr2% thr3% thr4%
thr5% thr6% thr7% thr8%
Router(config-if)# no rcv-queue random-detect
max-threshold [ queue_id ]
Step 5
Router(config-if)# rcv-queue random-detect
queue_id
Router(config-if)# no rcv-queue random-detect
[ queue_id ]
Step 6
Router(config-if)# end
Step 7
Router# show queueing interface type
1. type = fastethernet, gigabitethernet, or tengigabitethernet
Configuring a WRED-Drop and Tail-Drop Transmit Queue
These port types have both WRED-drop and tail-drop thresholds in their transmit queues:
