Mapping Cos Values To Drop Thresholds - Cisco 7609 Configuration Manual

Chapter 32 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.
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
<...Output Truncated...>
Receive queues [type = 1q4t]:
<...Output Truncated...>
queue tail-drop-thresholds
<...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:

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.
End with CNTL/Z.
