Re: [ovs-discuss] Anybody knows how we can dynamically change vxlan dst_port by openflow load, move or set_field action?

I also face that problem in my OPNFV APEX deployment. I hope, it is fixed soon. Best regards, Ahmed On Sat, Nov 26, 2016 at 11:08 PM, Ben Pfaff wrote: > On Thu, Nov 24, 2016 at 02:39:43AM +, Yang, Yi Y wrote: > > I noticed vxlan module always uses tp_dst from tunnel metadata

[ovs-discuss] What is the minimum Linux kernel version ovs 2.6.1 build requires?

Hi, folks I tried to build ovs 2.6.1 in Ubuntu trusty 64 with the below configuration options, but it failed, it is ok when I use the same way to build in Ubuntu 16.04 which has Linux kernel 4.4. What is the minimum Linux kernel version ovs 2.6.1 build requires? ./configure --prefix=/

Re: [ovs-discuss] [ovn] ovn-trace ct_actions not implemented

One initial, trivial, step might be to just have every ct_next respond that the flow is established. Then at least it would be possible to see how packets flow through the system in the normal case. I noticed that you were getting DHCP-related errors from ovn-trace. I have a patch out that

Re: [ovs-discuss] [ovn] ovn-trace ct_actions not implemented

ct_lb is tricky. I guess, the default should be to just pick the first option. On 30 November 2016 at 08:24, Ben Pfaff wrote: > One initial, trivial, step might be to just have every ct_next respond > that the flow is established. Then at least it would be possible to see > how

Re: [ovs-discuss] Anybody knows how we can dynamically change vxlan dst_port by openflow load, move or set_field action?

I think this issue is not that simple. It depends on how you use it. For normal use cases, a tunnel port will terminate the tunnel traffic, so a packet sent to a tunnel port will never be from another tunnel port, so no tunnel metadata is available for the first packet, but for the packets

[ovs-discuss] Streaming telemetry

Can I configure OVS in Openflow mode to constantly send telemetry data (ofstats) to a particular configured controller without the controller polling for data? Or is there an other way? Thanks /Shivaram ___ discuss mailing list disc...@openvswitch.org

[ovs-discuss] Debugging OVS

Hello, I find it difficult to debug OVS files without any debuggers. Would you suggest me to use GDB or is there any specific techniques to debug the problem ? As both user space and kernel space modules in OVS run as daemon process will I be able to debug it using GDB ? Thank you, Ajeeth Kannan

[ovs-discuss] ovs-testcontroller

Hi Folks, Does OVS provide a controller so that we can use it in mininet to act as the OVSController? Previously it was named OVSController and later to ovs-testcontroller. But now I cannot find such a file in the master branch of OVS Best Regards, Ashish Kurian
