Three different configurations are available for the switch interface. The configurations are bandwidth shape, share, and limit. You can also configure egress queue 1 as the priority queue. If the priority queue is enabled, SRR services it until it is empty before servicing the other three queues. However, in ingress priority queue, SRR services the priority queue with the configured value.

But A while back I ran into a problem that indicated otherwise. I guess I just need to run a test case in the lab to verify it. So for test questions go with what the book says.

It says if you have Priority-queue out on an interface, SRR is ignored for the priority queue, and it is serviced until empty.

It prevents the Priority queue from starving out the other queues (that are shared). Acts similiar to the Policy-map "Priority" command on the routers. The SRR shaped command set a minimum bandwidth guarantee on the remain queues. Also similar to the Policy-map "Bandwidth" command on the router.

As I would normally understand it, to enable the priority queue you need the following command on a port: priority-queue out If you use this command SRR shaping and sharing is ignored for the priority-queue. priority-queue with that command is serviced until empty, so no srr involved at all. So how can I "guarantee traffic for the priority queue" while also shaping queue 1 to 30%. Seems like conflicting statements...
