Hi,All
I want to use the QoS feature of OpenvSwitch to control the bandwidth based on
the vlan id(Scene 1) or port id(Scene 2).
So I deployed it as showed bellow,and configured the qos rules,the flows,and
used iperf tool to test it.
But the result is disappointment.
Scene 1:

1)Set QoS:
ovs-vsctl set port bond0 qos=@qos -- --id=@qos create qos type=linux-htb\
queues:1=@queue_data \
queues:2=@queue_storage -- \
--id=@queue_data create queue other-config:min-rate=200000000
other-config:max-rate=200000000-- \
--id=@queue_storage create queue other-config:min-rate=800000000
other-config:max-rate=800000000
2)OVS in host1：
Flows of ovsbr:
priority=100,in_port=1,dl_vlan=1002 actions=set_queue:2,NORMAL
priority=50,in_port=1 actions=set_queue:1,NORMAL
priority=2,in_port=1 actions=drop
priority=1 actions=NORMAL
Flows of br-int:
priority=3,in_port=1,dl_vlan=1002 actions=mod_vlan_vid:1002,NORMAL
priority=2,in_port=1 actions=drop
priority=1 actions=NORMAL
Can you check "tc -s -d class show dev bond0" and see if the queues are
set on bond0? If so, the queue_ids will mostly be equal to n+1, n being
the value set in the queue table. From my understanding,
https://github.com/openvswitch/ovs/blob/master/lib/netdev-linux.c#L3924
does this.
What is the bandwidth that iperf shows when the packets are not shaped
(without queues)?
3)iperf -c 10.10.12.4 -P 20,but the result is not 800M
[root@host1 ~]# iperf -c 10.10.12.4 -i 1 -t 100 -P 20 |grep SUM

1)Set QoS:

priority=1000,in_port=5 actions=set_queue:1,NORMAL
priority=1000,in_port=4 actions=set_queue:2,NORMAL
priority=900 actions=NORMAL
3)iperf -c 10.10.12.4 -N 5,the bandwidth is 940M
4)At the same time,iperf -c 192.168.4.3 -P 50,the bandwidth for 10.10.12.4 down
to 150M(not the min-rate).

Could anybody help me find why and how to solve it ?
Any help in this regard will be appreciated.
