I agree with Jim...
If you want to suppress dslw on an interface once it reaches 30% compacity of t
he link CAR is the way to go.
You would have to take the interface rate in bits * .3.
10MB 10000000
30% 3MB 3000000
Then take the minimum normal burt which I believe is 8000 bytes & convert that
to bits (64000 bits).
Take 300000 - 64000 = 2936000
And that give you your starting rate.
Rate 2936000 bits
normal burst 8000 bytes, or 64000 bits
maximum burst 8000 bytes, or 64000 bits
This way 2936000 + 64000 = 3000000 bits.
The set exceed action drop.
Set it to an access-list with port 2065 & determine if it should be input/ouput
, or both.
Guess it depends on the question.
My two cents,
Dan

Custom queuing doesn't suppress flow to 30%. This type of queuing only comes
into play if the interface is saturated. If DLSW is the only traffic present
it will consume 100% of the available bandwidth.
I think you might need to look at CAR as a solution to the problem.
I'm also curious where the original poster discovered this question? What
practice material is it from? Please reply.

Not certain if this is what you are looking for. I don't think the queue
will supress packets, it just put the packets for the next go around and let
the default traffic have their chance:
int ethernet 0
ip addr 123.4.5.6 255.255.255.0
custom-queue-list 1
queue-list 1 protocol ip list 101 1 <--- dlsw traffic queue-list 1 default 2
<---- other traffic
access-list 101 permit ip any any eq 2065
access-list 101 permit ip any eq 2065 any
access-list 101 permit ip any any eq 2067
access-list 101 permit ip any any eq 1981
access-list 101 permit ip any any eq 1982
access-list 101 permit ip any any eq 1983
queue-list 1 queue 1 byte-count 1500 <--- 30% of total bytes queue-list 1
queue 2 byte-count 3500 <--- 70% of total bytes
