basic QOS not working on HPE 5130

Hi,

I am trying a very basic QoS setup on 5130 switches. The goal is to have dscp EF tagged traffic priotitized over regular traffic. Topology is as follows :

[Computer]--1Gb link---[5130 Switch]--100Mb transit link--[5130 Switch]--[Computer]

I have followed the COS and ACL configuration guide, trying both SP and WRR methods, but couldn't get it to work : overloading the 100 Mb/s transit link between my 2 switches (using iperf 3) with 200 Mb/s multiple UDP streams of regular packets and one 5 Mb/s UDP stream of EF-tagged packets, the EF tagged stream gets reduced to about 2-3 Mb/s. However I can see that both regular packets and EF-tagged packets are set in their respective queues, as per result of the "dis qos queue-statistics interface g1/0/X outbound" command.

I tried the last R32 and last R31 firmware versions, with same results.

One strange thing I notice is that on the 5130 I can't see the "dropped" counters with the "dis qos queue-statistics interface g1/0/X outbound", see example below :

###################

same command on a 5510 (with no qos configuration), we see the "dropped" counters :

So I wonder if this is related ? Is there something to switch on the 5130 to enable packets dropping as per the QOS configuration ?
Did anyone manage to successfully implement QoS on the 5130 series ?

thanks.
