Important Considerations

■Because you cannot configure a rate limit for queue 2, the Administration Console prompts you to enter a rate limit only if you select queue 1.

■When you assign priority values to a given queue, the system automatically assigns the remaining priority values to the other queue.

■If CoS is disabled, you can still modify the queue settings; however, they do not affect traffic until CoS is enabled.
