Re: 3560 SRR sharing bandwidth

Guys: I am wondering if there is a way to police the traffic for the
priority queue (queue-1 in this case).For example, if we use "priority-queue
out" in this configuration, how do we avoid starving of other queues. Based
on my reading it appears that the moment you put this command
"priority-queue out" Q-1 becomes the king and can use whatever bandwidth it
demands ignoring the shaping/sharing command !!
Any guidance will be greatly appreciated!
