Re: How to use dpdk ovs

Hi,
Below are the seps that I followed to get DPDK with OVS. Some of the 
paths need to be changed to your env..
#12 Test Switching using OpenVSwitch with DPDK **************
#--- Setup the ifaces as dpdk..
cd /home/vnspteam01/dpdk-1.7.1
cd /home/vnspteam01/dpdk-1.8.0
sudo modprobe uio
sudo modprobe cuse
sudo rmmod igb_uio
sudo rmmod rte_kni
sudo insmod x86_64-native-linuxapp-gcc/kmod/igb_uio.ko
#**** Assign the dpdk capable interfaces to igb_uio driver
tools/dpdk_nic_bind.py --status
sudo /home/vnspteam01/dpdk-1.7.1/tools/dpdk_nic_bind.py -b igb_uio 
0000:02:00.0
sudo /home/vnspteam01/dpdk-1.7.1/tools/dpdk_nic_bind.py -b igb_uio 
0000:02:00.1
/home/vnspteam01/dpdk-1.7.1/tools/dpdk_nic_bind.py --status
#--- Setup the openVswitch
su -l
cd /home/vnspteam01/openvswitch-2.3.1
pkill -9 ovs
mkdir -p /usr/local/etc/openvswitch
mkdir -p /usr/local/var/run/openvswitch
rm -rf /usr/local/etc/openvswitch/conf.db
ovsdb/ovsdb-tool create /usr/local/etc/openvswitch/conf.db 
vswitchd/vswitch.ovsschema
#Start ovsdb-server
ovsdb/ovsdb-server --remote=punix:/usr/local/var/run/openvswitch/db.sock 
--remote=db:Open_vSwitch,Open_vSwitch,manager_options --pidfile --detach
utilities/ovs-vsctl --no-wait init
#Start vswitchd:
export DB_SOCK=/usr/local/var/run/openvswitch/db.sock
vswitchd/ovs-vswitchd --dpdk -c 0x3 -n 4 --syslog syslog -- 
unix:$DB_SOCK --pidfile --detach
#Add bridge & ports
utilities/ovs-vsctl add-br ovs-br0 -- set bridge ovs-br0 
datapath_type=netdev
utilities/ovs-vsctl add-port ovs-br0 dpdk0 -- set Interface dpdk0 type=dpdk
utilities/ovs-vsctl add-port ovs-br0 dpdk1 -- set Interface dpdk1 type=dpdk
#display
utilities/ovs-vsctl show
utilities/ovs-vsctl list interface dpdk0
utilities/ovs-vsctl list interface dpdk1
#Add test flows
utilities/ovs-ofctl del-flows br0
# Add flows between port 1 (dpdk0) to port 2 (dpdk1)
utilities/ovs-ofctl add-flow br0 in_port=1,action=output:2
utilities/ovs-ofctl add-flow br0 in_port=2,action=output:1

Ravi
