server42dpdk and LAB(OVS)

How to connect server42dpdk to lab OVS switches.

First way with pipework

• add kilda_server42_control_switch_to_vlan_3000: "3000=00:00:00:00:00:00:01:01,00:00:00:00:00:00:01:02,00:00:00:00:00:00:01:03" to confd/vars/main.yaml
• uncomment no_server42_server_stub and comment no_server42_server in confd/vars/docker-compose.yaml
• build and run kilda make up-stable
• shutdown server42-server container docker-compose stop server42-server
• run server42 with bash docker-compose run --use-aliases server42-server bash
• create lab with lab service
• connect both docker instances with pipework sudo ./pipework br_kilda_dpdk -i eth10 <instance id> 0/0
• create flow on lab
• run server42 with command ./server42 -c 0x1f --vdev=net_pcap0,iface=eth10,phy_mac=1 --no-huge -- --debug
• find server42 mac with sudo tcpdump -elnXXi br_kilda_dpdk. In case 02:70:63:61:70:00 > 00:00:00:00:01:02 server42-adress is 02:70:63:61:70:00
• put property with correct mac address to kilda switch properties and enable server42 rtt
• in lab instance add new link for strip server42 transport vlan ip link add link eth10 name eth10.3000 type vlan id 3000
• up interface sudo up ip link set up dev eth10.3000
• create new port for server42 in switch ovs-vsctl add-port sw01 eth10.3000 -- set interface eth10.3000 ofport=10. Here 3000 is transport vlan, sw01 is ovs switch and eth10 interface connected to br_kilda_dpdk

Second way with raw commands

lab - 3116a0642ea3 s42 - 2fd35a9c27ee

ip link add dev s42_ns type veth peer name s42_main
ip link add dev lab_ns type veth peer name lab_main
vconfig  add lab_ns 3000
brctl addbr s42
brctl addif s42 s42_main
brctl addif s42 lab_main
ip link set up dev s42
ip link set up dev s42_main
ip link set up dev lab_main
ip link set s42_ns netns 2fd35a9c27ee
ip link set lab_ns.3000 netns 3116a0642ea3
ip netns exec 2fd35a9c27ee ip link set up dev s42_ns
ip netns exec 3116a0642ea3 ip link set up dev lab_ns.3000
ip link set up dev lab_ns
ovs-vsctl add-port sw01 lab_ns.3000 -- set interface lab_ns.3000 ofport=10
