This chapter describes the Cisco NX-OS quality of service (QoS) commands that begin with W.
To map assigned class of service (CoS) values to select one of the egress queues, use the wrr-queue cos-map command. To return the CoS map to the default setting, use the no form of this command.
wrr-queue cos-map queue-id cos1... cos8
no wrr-queue cos-map queue-id cos1... cos8
CoS values that are mapped to select a queue. Enter up to eight CoS values. Separate each value with a space. The range is from 0 to 7. |

Note This command is applicable only to Layer 3 multicast traffic.
You can use this command to distribute traffic into different queues, where each queue is configured with different weighted round robin (WRR) parameters.
You can configure a maximum of four multicast queues for Layer 3 multicast traffic. We recommend that you configure at least one class of service (CoS) value for each multicast queue.
This example shows how to map CoS values 0 and 1 to queue 1:
