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

Purpose

Step 1

 

 

Router(config)# interface type1 slot/port

Selects the interface to configure.

Step 2

 

 

Router(config-if)#priority-queue cos-map queue_#

Maps CoS values to the receive and transmit

 

cos1 [cos2 [cos3 [cos4 [cos5 [cos6 [cos7

strict-priority queues.

 

[cos8]]]]]]]

 

 

Router(config-if)#no priority-queue cos-map

Reverts to the default mapping.

Step 3

 

 

Router(config-if)# end

Exits configuration mode.

Step 4

 

 

Router# show queueing interface type1 slot/port

Verifies the configuration.

 

 

 

1.type = fastethernet, gigabitethernet, or tengigabitethernet

When mapping CoS values to the strict-priority queues, note the following information:

•The queue number is always 1.

•You can enter up to 8 CoS values to map to the queue.

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. End with CNTL/Z.

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
