Comments on: QoS operation on AR28 and AR46 with VRP 3.40 http://www.kuncar.net/blog/qos-operation-on-ar28-and-ar46-with-vrp-3-40/2009/ Sat, 03 Dec 2011 23:57:52 +0000 hourly 1 http://wordpress.org/?v=3.3.1 By: tnk http://www.kuncar.net/blog/qos-operation-on-ar28-and-ar46-with-vrp-3-40/2009/comment-page-1/#comment-720 tnk Sun, 28 Aug 2011 20:17:31 +0000 http://www.kuncar.net/blog/?p=312#comment-720 Hi Lukasz, the above is just about how to create QoS stuff not really about SNMP - I think I did write something about how to enable SNMP but I am not sure. Anyway as far as I remember for decoding the SNMP traps you need MIB files specific to what you are trying to see (i.e. networking MIB contains subset of OIDs which is differente to QoS MIB) and they are released only by Huawei on per request basis. It might be that something has changed though. Anyway for SNMP to work you definitely need to enable it (I think it is about 3 commands in system-view where you define target, version and community string). If can be more specific in your question I would gladly answer you - but as always I do not have AR routers at my disposal at this moment so I might not be able to help with everything.

I am trying to poll some data using snmpwalk but no success. Hi David,

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

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,
