[dpdk-users] OVS-DPDK bridge with DPDK physical ports doesn't route the ping packets

[Mona ElSaadawy]

Hi,

I'm trying to build up an OVS-DPDK bridge that should connect two different physical hosts. I followed this tutorial to install DPDK and OVS with DPDK configuration :http://docs.openvswitch.org/en/latest/intro/install/dpdk/ and followed the instructions in PHY-PHY in http://docs.openvswitch.org/en/latest/howto/dpdk/ to build up the intended setup.  To test this setup, I directly plugged the physical NICs of node-01 and Node-03 into the DPDK physical NICs at node 02. Then I tried to ping Node-03 from Node-01 but it doesn't work though the ARPing is working and when I run dump-flows on the OVS-DPDK bridge, I can find the ping packets matched in their corresponding flows but can't received at the connected hosts. I tried to write the destination MAC address for each flow to ensure the delivery, but it doesn't work either. I tried also to enable the flow negotiation and flow control for both the receiving and transmitting queues of the bridge DPDK ports by running:

Using Open vSwitch with DPDK - Open vSwitch Documentation<http://docs.openvswitch.org/en/latest/howto/dpdk/>
docs.openvswitch.org
OVS with DPDK Inside VMs¶. Additional configuration is required if you want to run ovs-vswitchd with DPDK backend inside a QEMU virtual machine. ovs-vswitchd creates separate DPDK TX queues for each CPU core available.




ovs-vsctl set Interface <DPDK port  name> options:tx-flow-ctrl=true

ovs-vsctl set Interface <DPDK port  name> options:rx-flow-ctrl=true

ovs-vsctl set Interface <DPDK port  name> options:flow-ctrl-autoneg=true

It doesn't work.

I also enabled the IP forwarding in the both communicating nodes (1 & 3).

So can anyone please help in figuring out what is wrong in this setup?.A thing to add. The two DPDK physical interfaces added to the OVS-DPDK bridge is on the same NIC and it's:

BCM57416 NetXtreme-E 10GBase. My system has 4 cores with hyper-threading and one socket.
