Configuring PFC QoS
This example shows how to configure receive queue 1/threshold 1 and transmit queue 1/threshold 1 for
Gigabit Ethernet port 2/1:
Router# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)# interface gigabitethernet 2/1
Router(config-if)# wrr-queue threshold 1 60 100
Router(config-if)# end
Router#
This example shows how to verify the configuration:
Router# show queueing interface gigabitethernet 2/1
Transmit queues [type = 2q2t]:
<...Output Truncated...>
queue tail-drop-thresholds
--------------------------
1 60[1] 100[2]
2 40[1] 100[2]
<...Output Truncated...>
Receive queues [type = 1q4t]:
<...Output Truncated...>
queue tail-drop-thresholds
--------------------------
1 60[1] 100[2] 40[3] 100[4]
<...Output Truncated...>

Mapping CoS Values to Drop Thresholds
These sections describe mapping CoS values to drop thresholds:
Note Enter the show queueing interface {ethernet | fastethernet | gigabitethernet | tengigabitethernet}
slot/port | include type command to see the queue structure of a port.
These sections describe how to map CoS values:
• Mapping CoS Values to Standard Receive-Queue Thresholds, page 32-60
• Mapping CoS Values to Standard Transmit-Queue Thresholds, page 32-61
• Mapping CoS Values to Strict-Priority Queues, page 32-61
• Mapping CoS Values to Tail-Drop Thresholds on 1q4t/2q2t LAN Ports, page 32-62
When CoS values to thresholds, note the following:
• Queue number 1 is the lowest-priority standard queue.
• Higher-numbered queues are higher priority standard queues.
• You can map up to 8 CoS values to a threshold.
