I don't think this is the right forum for this question, since it doesn't seem
related to OVS. However, if I were to speculate, my guess is that the
forwarding ASIC doesn't support modifying the ToS bits, so the packets are
being forwarded to the management CPU to handle these packets. You cou
Hi
We are working on a research project that involves HP OpenFlow-enabled
switch (HP 3500 yl). We are facing some issues with performance
particularly when operating the switch in "OpenFlow" mode. The switch is
controlled via a desktop running the Ryu controller.
The rules on the switch match pa

sorry, it is a obvious mistake in writing. and after I corrected it, this
cmdline didn't work.

Hi,
I am debugging failures in OpenStack Neutron functional tests. The sequence of events is the following:
1) An interface is added successfully to a bridge
2) The addition of the interface is logged by ovs-vswitchd
3) The test fails because it cannot find the interface when trying to move

Thanks for reply. All I've got from your link is that Ryu team implemented
establishing of BFD sessions between Ryu and whatever: controller

In opposite, I'm asking about reacting on BFD session change *inside* OvS.
All I've got from ovs mans and sources is that I can run BFD an

rest of it, it sounds like you need to spend a lot of time with google and
develop some specific questions. You probably want to start with mininet.

Hello,
I have installed OVS 2.7 running. When I do:
# ovs-vsctl add-port br0 dpdk-p0 -- set Interface dpdk-p0
type=dpdk options:dpdk-devargs=:82:00.0
ovs-vsctl: Error detected while setting up 'dpdk-p0': Error attaching
device ':82:00.0' to DPDK. See ovs-vswitchd log for details.

You can use dpdk tool 'pdump' to capture packets

Hi guys,
My scenario is as follows:
OVS 2.7.90 with two dpdk ports connected to IXIA two dedicated ports.
From IXIA port1 I send double-tagged traffic to port2. I am trying to
remap inner and outer tags of the frames with group chaining and at last
send it out to port 2 of the OVS.

I need a real dataset of network traffic with diverse matching fields.
this is required for 2 different tasks
based on this dataset i need to populate :

- datapath cache (task 2)
my questions :
- is there any dataset available?
