running IOS 12.2(40)SE. This seem to do strict priority queueing only which means that that queue will be serviced until it is emptied, then other queues will be serviced.
We will be pumping lots of voice calls through a few of these 3400s on a metro fiber ring and I need to apply the appriopriate QOS for voice. I'm familiar with LLQ in the router world and autoqos in the 3750/3650 switch world, but not with this switch.
Is there a white paper that speaks directly to VoIP on the 3400? The QOS section of the config guide doesn't help when looking for config examples for voice except to state that voice can be mapped to the priority queue, but it is not LLQ based.
I don't want to police voice because the potential of dropped packets could affect all calls, but I need to make sure that voice traffic gets priority over all else - without starving out the other traffic.
