Chapter 41 Configuring PFC QoS
Mapping CoS Values to Strict-Priority Queues
To map CoS values to the receive and transmit strict-priority queues, perform this task:
Command
Step 1
Router(config)# interface type
Step 2
Router(config-if)# priority-queue cos-map queue_#
cos1 [ cos2 [ cos3 [ cos4 [ cos5 [ cos6 [ cos7
[ cos8 ]]]]]]]
Router(config-if)# no priority-queue cos-map
Step 3
Router(config-if)# end
Step 4
Router# show queueing interface type
1. type = fastethernet, gigabitethernet, or tengigabitethernet
When mapping CoS values to the strict-priority queues, note the following information:
•
•
This example shows how to map CoS value 7 to the strict-priority queues on Gigabit Ethernet port 1/1:
Router# configure terminal
Enter configuration commands, one per line.
Router(config)# interface gigabitethernet 1/1
Router(config-if)# priority-queue cos-map 1 7
Router(config-if)# end
Router#
This example shows how to verify the configuration:
Router# show queueing interface gigabitethernet 1/1
<...Output Truncated...>
Transmit queues [type = 1p2q2t]:
<...Output Truncated...>
Receive queues [type = 1p1q4t]:
<...Output Truncated...>
<...Output Truncated...>

The queue number is always 1.
You can enter up to 8 CoS values to map to the queue.

Purpose
Selects the interface to configure.
Maps CoS values to the receive and transmit
strict-priority queues.
Reverts to the default mapping.
Exits configuration mode.
Verifies the configuration.
