Best regards Wolfgang Hi David,

where can I find your eMail address, I’ve gotten the configuration from the ISP from one of our locations.

Best regards

It is likely that they use either the "voice queue" which is present on certain Huawei boxes or the use the PQ+WFQ mechanism which was the default setting on some boxes and which would resolve in the same behavior. I could probably tell you more if you could send me the Huawei configs to my e-mail. Best Regards David Hi Wolfgang,

I have read your article about configuring QoS, very interesting. Our ISP is using this equipment, and there is also a Qos configuration in 4 classes. We have 8 locations in Germany which are connected together, some have Cisco equipment. Our experience is, is only one using one of the three "higher" classes, the bandwidth reservation will reserve the whole bandwidth for this user, whether needed or not. So the "default" class, which has 20% of the bandwidth in the worst case, will only be at this 20%, this percentage bandwidth configuration is wasting bandwidth. I don't know which firmware these ARs are running, but this is a great bug. On the Ciscos also with the "same" configuration (percentage bandwidth) the behavior is different: Assume a 4Mb connection, 20% is reserved for VoIP, if only one people is using the telephone, the lasting 18% or so are shared with the other classes, on the Huawei, the 20% are exclusive given to the one, which is using the VoIP telephone. Best regards Wolfgang Hi,
