Subject: [dpdk-users] Ping doesn't work with OVS-DPDK bridge with DPDK physical ports but ARPing works
Date: Tue, 4 Dec 2018 18:28:59 +0000 [thread overview]
Message-ID: <YTXPR0101MB2270B2BD9CEE75ED288D178FA3AF0@YTXPR0101MB2270.CANPRD01.PROD.OUTLOOK.COM> (raw)
Hi,
I'm trying to build up an OVS-DPDK bridge that should connect two different physical hosts. So I basically have three physical nodes, one is the traffic generator and one for the sink and the third physical host has the OVS-DPDK bridge that connect the two other nodes. 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 two communicating nodes into the DPDK physical interfaces of OVS-DPDK bridge at the third host. Then I tried to ping from one of the two communicating nodes to the other but it doesn't work though the ARPing is working . In addition, 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 and the ARP table of the OVS-DPDK bridge is empty. 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:
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.
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. 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?
