Hello All, I did upgrade to dpdk-17.05 and ovs-2-7.1 and create a vdev - af_packet device according the config script below This tap device connects the ovs-dpdk to a name space The problem is that this tap00 device is linkdown - (never reach RUNNING state ) - hence no pkt is received transmitted on this interface although the tap0 creation in ovs is OK, I'm attaching the config script and output of netstat and ifconfig in the namespace Can someone please tell me how to activate the tap0 ?
Config script : cd ../dpdk-17.05/usertools/ modprobe uio insmod ../x86_64-native-linuxapp-gcc/kmod/igb_uio.ko ifconfig ens3 down ./dpdk-devbind.py --bind=igb_uio 0000:00:03.0 ./dpdk-devbind.py --status cd - pkill -9 ovs rm -rf /usr/local/var/run/openvswitch rm -rf /usr/local/etc/openvswitch/ rm -f /usr/local/etc/openvswitch/conf.db mkdir -p /usr/local/etc/openvswitch mkdir -p /usr/local/var/run/openvswitch ./ovsdb/ovsdb-tool create /usr/local/etc/openvswitch/conf.db ./vswitchd/vswitch.ovsschema ./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 echo 8192 > /sys/devices/system/node/node0/hugepages/hugepages-2048kB/nr_hugepages echo 8192 > /sys/devices/system/node/node1/hugepages/hugepages-2048kB/nr_hugepages mkdir -p /mnt/huge mkdir -p /mnt/huge_2mb mount -t hugetlbfs none /mnt/huge_2mb -o pagesize=2MB modprobe openvswitch export DB_SOCK=/usr/local/var/run/openvswitch/db.sock ./utilities/ovs-vsctl --no-wait set Open_vSwitch . other_config:dpdk-init=true ./vswitchd/ovs-vswitchd unix:$DB_SOCK --pidfile --detach ./utilities/ovs-vsctl set Open_vSwitch . other_config:pmd-cpu-mask=0x80 utilities/ovs-vsctl --may-exist add-br br-int \ -- set Bridge br-int datapath_type=netdev \ -- br-set-external-id br-int bridge-id br-int \ -- set bridge br-int fail-mode=standalone ip tuntap add dev tap0 mode tap ovs-vsctl add-port br-int tap0 -- set Interface tap0 type=dpdk \ options:dpdk-devargs=eth_af_packet0,iface=tap0 ip netns add red ip link set tap0 netns red ip netns exec red ip addr add 1.1.1.20/24 dev tap0 ip netns exec red ip link set tap0 up utilities/ovs-vsctl --may-exist add-port br-int vxlan0 \ -- set interface vxlan0 type=vxlan options:remote_ip=172.31.100.44 options:key=1000 utilities/ovs-vsctl --may-exist add-br br-phy \ -- set Bridge br-phy datapath_type=netdev \ -- br-set-external-id br-phy bridge-id br-phy \ -- set bridge br-phy fail-mode=standalone \ other_config:hwaddr=02:d7:d1:26:84:e5 utilities/ovs-vsctl --timeout 10 --may-exist add-port br-phy dpdk0 -- set Interface dpdk0 type=dpdk options:dpdk-devargs=0000:00:03.0 ip addr add 172.31.100.80/24 dev br-phy ip link set br-phy up ip link set br-int up iptables -F utilities/ovs-appctl ovs/route/show ip netns exec red bash ifconfig lo up ################################# netstat -v -s -e Ip: 7 total packets received 0 forwarded 0 incoming packets discarded 7 incoming packets delivered 14 requests sent out Icmp: 7 ICMP messages received 0 input ICMP message failed.
