Is there command line tool or option to show flow miss timestamp and flow

In other words, can we know when flow miss happens and when flow insert
happens?

Hi.
In OVS 2.4 version, it includes DPDK as mainstream since there is
INSTALL.DPDK.md.
Is it different from OVDK?
In other words, OVS + DPDK in version OVS 2.4 is not OVDK?

Thank you for reply and I am very clear.
Is there some work which compares default ovs and ovs with dpdk in terms of
performance like throughput?

Hi.
I am new to DPDK.
The purpose of DPDK is to bypass kernel layer when it forwards to user
space.
My first question is how DPDK works with OVS.
Since OVS has two tables in user space and kernel space, the second packet
is matched in kernel tables after one packet is missed and controller

Hi.
Does OVS supports header match after skipping some header fields and use
match rules with the rest of header?
For example, I have tunneled packet.
L2-IPV4(1)-UDP-GRE-IPV4(2)-TCP.
In this case, does ovs check IPV4(2) *without virtual port mechanism?*
I read ovs-ofctl.8.pdf, but it does not su
I also think it is controller's job.
Thanks. Ben.

Hi.
Is there an option to back up inserted flow rules and restore them when
ovs-vswitchd is restarted after it die due to programming error?
I read the open Vswitch manuals, but It does not have this option.
There is "flow-restore-wait" option, but it is not my purpose.

Hello, according to ovs-vsctl, we can add queues per ethernet port.
It looked like that it uses mechanisms which TC uses.
Is it right?
Does ovs support qos(with queue) for tunnel ports like gre, vxlan, and list
and so on?
Thanks,

What I thought is to generally use metadata as matching rule in datapath.
It is not just between tables.

But, it is in "struct flow" in lib/flow.h.
It is not from "struct sw_flow_key" in /datapath/flow.h.
I assume metadata is used in action in datapath.
Is it right?

Hi, I have a simple question.
When we use metadata as flow-rule,
Does all traffic forward ofproto to match it because there is no match
field in "struct sw_flow" in datapath?

In FAQ, there is way of configuring one ip address to OVS like this.
ifconfig eth0 0.0.0.0
ifconfig br0 192.168.128.5
There are some sentences.
"If your only connection to the machine running OVS is through the
IP address in question, then you would want to run all of these
commands on a
path or is there another
cache in OVS?

Table entries in datapath disappear after short time.
Does they use timer in kernel or other ways?
What is the idle timeout?
If someone know, please let met know where the source code defines.

Hi,
Can current OVS support OFPT_EXPERIMENTER?
I think it does not support.
In handle_openflow__() in ofproto.c, I cannot find OFPTYPE_EXPERIMENTER.
Is there anyone who know this??

Hi, Can I bind a virtual port to a physical port?
I mean if the packet enters a physical port, it will automatically go to a
virtual port without flow rule( ex) if the packet arrives at port
1(physical), it will be sent to port 2(virtial port) ).
Thanks.
