Usage Guidelines


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.

Examples

This example shows how to map CoS values 0 and 1 to queue 1:

switch(config)# wrr-queue cos-map 1 0 1
switch(config)#
