Well, you are still assigning the same percentage of bandwidth
relatively to the max allocable bandwidth (75%). Not sure it's very
clear.
Also, with CQ, there is this queue #0 (system queue) that you don't
configure. Queue #0 borrows the bandwidth that it needs. When we say
that queue #1 in CQ takes 9% of the total bandwidth, it's not completely
true. It takes 9% of the bandwidth that we can assign to the 16
configurable queues. The queue 0 shouldn't take 25% of the bandwidth but
like CBWFQ, there is this idea of a max bandwidth that you allocate to
the queues and it's inferior to 100% of the bandwidth of the link.

Hmmmm? Interesting thinking on your part.
If you do it that way though you really wouldn't be allocating the same
amount of BW that the CQ was allocating to that traffic right? Am I
missing something here?

Hi Scott,
If I may, I wouldn't allocate 100% of the bandwidth to the classes and
would keep the default to 75 %. If you want to assign more than 75% to
the classes, that's fine but not up to 100%.
In other words, I'd rather use this formula for queue #1:
128 kbps * (1000/11500) * 0.75 = 8 (bandwidth 8)
In percentage, this gives us:
(1000/11500) * 0.75 = 6.5 (bandwidth percent 6)
May be I am missing something here so any input?

Here is my attempt. For these scenarios if I can spot the bandwidth
percent real quick then I just use the 'bandwidth percent' command. In
my own freakish way of thinking I can convert it quicker using the
formula below. Tell me what you all think and please let me know if I
messed up somewhere.
BW of Link in kbps * (byte count / total byte count) = BW
For example:
Queue #1
---------
128 kbps * (1000 / 11500) = 11

Hi group,
I need to convert following CQ into CBWFQ
# queue-list 1 protocol tcp 1 telnet byte-count 1000 limit 100
# queue-list 1 protocol udp 2 domain limit 100
# queue-list 1 protocol tcp 3 ftp byte-count 3000
# queue-list 1 protocol dlsw 4 byte-count 5000
# queue-list 1 default 16 byte-count 1000
# interface serial 0/1
# custom-queue-list 1
can any body giude me...the serial interface is frame-relay encapsulated
...will i map the service on physical interface or under class-map
frame-relay?
thanks in advance
