Sounds about right, depending on what you are trying to achieve.
I guess you usually want to take each port to a different queue,
or else what's the point on using priority.
Courseware advise is to just use
queue-list 1 protocol ip 1 tcp 2065
queue-list 1 protocol ip 2 tcp 1981
...
The udp is used in DLSWv2 AFAIK, so in a cisco environment it's
not going to be needed...
but that's obviously subject to whatever you have been asked for.
