So I basically have three physical nodes, one is the traff= ic generator and one for the sink and the third physical host has the OVS-D= PDK bridge that connect the two other nodes. I followed this tutorial to in= stall DPDK and OVS with DPDK configuration http://docs.openvswitch.org/en/l= atest/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 two communic= ating nodes into the DPDK physical interfaces of OVS-DPDK bridge at the thi= rd host. Then I tried to ping from one of the two communicating nodes to th= e other but it doesn't work though the ARPing is working . In addition, whe= n I run dump-flows on the OVS-DPDK bridge, I can find the ping packets matc= hed in their corresponding flows but can't received at the connected hosts = and the ARP table of the OVS-DPDK bridge is empty. I tried to write the des= tination 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 f= or both the receiving and transmitting queues of the bridge DPDK ports by r= unning: ovs-vsctl set Interface options:tx-flow-ctrl=3Dtrue ovs-vsctl set Interface options:rx-flow-ctrl=3Dtrue ovs-vsctl set Interface options:flow-ctrl-autoneg=3Dtrue It doesn't work. I also enabled the IP forwarding in the both communicating nodes. A thing to add. The two DPDK physical interfaces added to the OVS-DPDK brid= ge is on the same NIC and it's: BCM57416 NetXtreme-E 10GBase. My system has 4 cores with hyper-threading an= d one socket. and here are my OVS and DPDK versions: ovs-vswitchd --version ovs-vswitchd (Open vSwitch) 2.10.90 DPDK 17.11.4 So can anyone please help in figuring out what is wrong in this setup?
