two hardware queues and changes the optional rate limit on queue 1

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.
