A Client with a main and a remote site entering to an MPLS network. I have consistent QoS politics and we have voice traffic (precedence 5, priority queue) with not delay variation in the delay when congestion occurs. But when the video traffic circulates (prec 4, bandwitdh command) the delay in this traffic increases when cogestion occurs. Is this behavior normal? how can to avoid this behavior?
Video is offen very variable in its bandwidth demand. It's possible your CBWFQ bandwidth statement provides enough bandwidth for your video's average bandwidth demand, but not enough to prevent queuing bursts. You could try increasing the bandwidth allocation. (Your video won't use any more average bandwidth, but a higher allocation means bursts are less likely to queue relative to other traffic.)
Another possible solution might be moving/converting the video to an LLQ class.
Since you mention MPLS, much can also depend on what your MPLS provider guarantees for IP Prec 4 traffic.
You might want to define an explict bandwidth allocation for your IP Prec 4 class.
You might want to stop using (implicit) FQ within class-default.
You might need to tune your shapers, either smaller Tc and/or define less bandwidth (to allow for L2 header bandwidth).
PE4 shows 1 Mbps Vbr-rt and CE4 shows 1 Mbps frame-relay? If these two interconnect you need to allow for the bandwidth difference between ATM and frame-relay (ATM uses more bandwidth because of cell header overhead and cell padding). Also, what's the max bandwidth of the frame-relay link since w/o a shaper (I believe) it's limited by the physical interface not CIR setting.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
