problem description: data are still transmitted to queue 0 even when use
set_queue:2
I created queues and then create flow by using "ovs-ofctl add-flow br0
actions=set_queue:2 --protocols=openflow13" , but no data are enqueued to queue
2, they are still enqueued
to queue 0. But if I use tc filter to set the rules, data could be transmitted
to queue 2.
My question is : how to solve this problem, I want to use this "set_queue"
command to finish my experiments.
I use the following command to create three queues:
ovs-vsctl -- set port br0 qos=@newqos \
-- --id=@newqos create qos type=linux-htb
other-config:max-rate=40000000 queues=0=@q0,1=@q1,2=@q2 \
-- --id=@q0 create queue other-config:min-rate=10000000
other-config:max-rate=10000000 \
-- --id=@q1 create queue other-config:min-rate=20000000
other-config:max-rate=20000000 \
-- --id=@q2 create queue other-config:min-rate=30000000
other-config:max-rate=30000000
ovs-vsctl list qos:

=====================
I use "ovs-ofctl add-flow br0 actions=set_queue:2 --protocols=openflow13" to
enforce data to be transmitted to queue 2, but the data are still transmitted
to queue 0:
OFPST_QUEUE reply (OF1.3) (xid=0x2): 3 queues
port LOCAL queue 0: bytes=32342937, pkts=248671, errors=0,
duration=2987889752.3375967296s
port LOCAL queue 1: bytes=0, pkts=0, errors=0, duration=2987889752.3375967296s
port LOCAL queue 2: bytes=0, pkts=0, errors=0, duration=2987889752.3375967296s
====================
However, if I use tc filter to set the rules, data could be transmitted to
queue 2:
