I would like to ask the pros of QoS,if Reducing the bandwidth and simultaneously applying QoS (QoS that prioritizes VoIP traffic) doesn't limit the effectiveness of QoS!
what I mean is that, since the rate limit is applied first to all traffic (so there will surely have been Dropped packets, and possibly RTP packets). so even if QoS which prioritizes VoIP traffic is configured I will have bad communications?
those who have already tested, your answers will help me.
If you police all traffic on the ingress, then the policer drops packets/frames - so there's no chance to recover them anywhere, since they're dropped.
What you might want to do: classify voice (signalling and media) on the ingress, police it, and police class default traffic as well. Then implement priority queuing for voice, on the ingress and the egress, so you have a wide path for voice.
