Subject: OVS_DPDK bridge with DPDK physical ports doesn't route the ping packets
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 try to ping Node-03 from
Node-01 but it doesn't work though the ARPing is working and whenI 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:
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 physical DPDK posts added to the OVS belong to one NIC chip
and when I try to show the MAC table of the OVS_DPDK bridge I found it empty.
