Hi Daniel,

I had to review again my notes and the documentation to tell for sure (wish
I knew it out of my head as earlier I was studying a lot of the lan qos
theory).

You are correct, the srr-queue bandwidth shape means nothing when you
configure the priority queue out. As it says on the doc:
"All four queues participate in the SRR unless the expedite queue is
enabled, in which case the first bandwidth weight is ignored and is not used
in the ratio calculation. *The expedite queue is a priority queue, and it is
serviced until empty* before the other queues are serviced. You enable the
expedite queue by using the priority-queue out interface configuration
command. "

So what I get is the settings are ignore completely for the calculation of
shared bandwidth for the other queues, and because the queue is serviced
until empty.

I'm all dizzy today from studying the LAN QoS and still can't say I know it
all. :-/
