Just a note while I come up for air…

On most switches with a hardware priority queue (egress expedite queue) like the 3550, it’s statically assigned to queue 4 (on switches with 4 queues). Some switches like the 4500s let you switch the queue, but generally it’s on silicon so you’re stuck. No problem.

However, on the 3560 it’s queue 1. Luckily the commands are different (wrr-queue vs srr-queue) but it’s not exactly obvious that the pq isn’t in the same place.

I haven’t checked the 3750 series, I suspect they’ll also be on queue 1.

    3750s are also queue 1, and use srr-queues.
