+
+This document shows an example of testing the dataplane in the third topology represented in the [topologies description](Topologies.md) with two pods equipped with two interfaces each that are bounded to VPP, using PROX as traffic generator. The `userspace-rapid-pod-t3-p1.yaml` and the `userspace-rapid-pod-t3-p2.yaml` files can be created by modifying the [Rapid pod definition file](./Configuration/Kubernetes/Rapid-pod/userspace-rapid-pod-2-interfaces-VPP.yaml).
+
+### Prepare VPP and deploy the kubernetes components
+
+- On Node 1:
+ - Start `vpp.service` with `startup.conf` file under `/etc/vpp`
+- On Node 2:
+ - Deploy network attachment `userspace-vpp-netAttach-memif.yaml`
+ - Deploy pods applying `userspace-rapid-pod-t3-p1.yaml` and `userspace-rapid-pod-t3-p2.yaml`
+
+### Configure PROX inside the pods
+
+- Generator Pod:
+
+ - Enter the generator pod with `kubectl exec -it userspace-rapid-pod-t3-p1 -- /bin/bash`
+
+ - copy the prox folder (it is shared between pods) to make changes on configuration files: `cp -r /opt/prox /opt/proxgen`
+
+ - search for the two memif socketfile names running :
+
+ ```
+ [root@userspace-rapid-pod-t3-p1 /]# cat /etc/podnetinfo/annotations | grep socketfile
+ userspace/configuration-data="[{\n \"containerId\": \"d3810ce7d4dee8f4cbcbfb7f3a53b86fd33481db282446b07dcb1bf4f1d7fa49\",\n \
+
+ "ifName\": \"net1\",\n \"name\": \"userspace-vpp-net\",\n \"config\": {\n \"engine\": \"vpp\",\n \"iftype\": \"
+
+ memif\",\n \"netType\": \"interface\",\n \"memif\": {\n \"role\": \"slave\",\n \"mode\": \"ethe

+

+ \"name\": \"net2\",\n \"sandbox\": \"/proc/17603/ns/net\"\n }\n ],\n \"dns\": {
+
+ }\n }\n}]"
+ ```
+
+
+
+ - copy the names `memif-*-net1.sock` and `memif-*-net2.sock`
+
+ - edit the `parameters.lua` changing the socketfile name and set the CPUs number for the main core, generator cores and latency cores:
+
+ ```lua
+ ...
+ eal="--socket-mem=256,0 --vdev=net_memif0,socket=/usrspcni/memif-d3810ce7d4de-net1.sock --vdev=net_memif1,socket=/usrspcni/memif-d3810ce7d4de-net2.sock"
+ mcore="14"
+ ...
+ gencores="15"
+ latcores="16"
+ ...
+
+ ```
+
+ - edit `prox.cfg` to configure the tasks properly for generating and receiving packets:
+
+ ```
+ [lua]
+ dofile("parameters.lua")
+
+ [eal options]
+ -n=4 ; force number of memory channels

+ ```
+
+ - Enter rapid folder and start PROX:
+
+ ```
+ [root@userspace-rapid-pod-t3-p1 /]# cd /opt/rapid/
+ [root@userspace-rapid-pod-t3-p1 rapid]# ./prox -f ../proxgen/prox.cfg -et
+ ```
+
+ ```
+ Usage: ./prox [-f CONFIG_FILE] [-a|-e] [-m|-s|-i] [-w DEF] [-u] [-t]
+ -f CONFIG_FILE : configuration file to load, ./prox.cfg by default
+ -e : don't autostart
+ -t : Listen on TCP port 8474
+ ```
+
+ 
+
+- Swap Pod:
+
+ - Enter the generator pod with `kubectl exec -it userspace-rapid-pod-t3-p2 -- /bin/bash`
+ - copy the prox folder (it is shared between pods) to make changes on configuration files: `cp -r /opt/prox /opt/proxswap`
+ - search for the two memif socketfile names like for the Generator Pod and copy the names `memif-*-net1.sock` and `memif-*-net2.sock`
+
+ - edit the `parameters.lua` changing the socketfile name and set the CPUs number for the main core (same as Generator Pod) and the swap cores:
+
+ ```lua
+ ...
+ swapone="17"
+ ...
+
+ ```
+
+ - edit `prox.cfg` to configure the tasks properly for swapping:
+
+ ```
+ [lua]
+ dofile("parameters.lua")
+
+ [eal options]
+ -n=4 ; force number of memory channels
+ no-output=no ; disable DPDK debug output
+ eal=--proc-type auto ${eal}

+ mode=master
+
+ [core $swapone]
+ name=swap1
+ task=0
+ mode=swap
+ rx port=p0
+ tx port=p1
+ drop=no
+ ```
+
+ - Enter rapid folder and start PROX:
+
+ ```
+ [root@userspace-rapid-pod-t3-p2 /]# cd /opt/rapid/
+ [root@userspace-rapid-pod-t3-p2 rapid]# ./prox -f ../proxgen/prox.cfg
+ ```
+
+ 
+
+### Configure VPP
+
+On Node 1 VPP should be configured to send the traffic between memif interfaces with `l2patch`:
+
+```
+[opnfv@worker ~]$ sudo vppctl
+ _______ _ _ _____ ___
+ __/ __/ _ \ (_)__ | | / / _ \/ _ \
+ _/ _// // / / / _ \ | |/ / ___/ ___/
+ /_/ /____(_)_/\___/ |___/_/ /_/
+
+vpp# show interface
+ Name Idx State MTU (L3/IP4/IP6/MPLS) Counter Count
+local0 0 down 0/0/0/0
+memif1/0 1 up 9000/0/0/0
+memif2/0 2 up 9000/0/0/0
+memif3/0 3 up 9000/0/0/0
+memif4/0 4 up 9000/0/0/0
+vpp# show l2patch
+no l2patch entries
+vpp# test l2patch rx memif1/0 tx memif3/0
+vpp# test l2patch rx memif4/0 tx memif2/0
+vpp# show l2patch
+ memif1/0 -> memif3/0
+ memif4/0 -> memif2/0
+```
+
+To check the socketfiles of the showed memif for the patch configuration run:
+
+```
+vpp# show memif
+sockets
+ id listener filename
+ 2 yes (1) /var/lib/cni/usrspcni/data/memif-d3810ce7d4de-net2.sock
+ 4 yes (1) /var/lib/cni/usrspcni/data/memif-ab82066a8020-net2.sock
+ 3 yes (1) /var/lib/cni/usrspcni/data/memif-ab82066a8020-net1.sock
+ 0 no /run/vpp/memif.sock
+ 1 yes (1) /var/lib/cni/usrspcni/data/memif-d3810ce7d4de-net1.sock
+
+...
+```
+
+### Configure rapid environment and files
+
+On Node 1 the environment and the file for running rapid should be set-up.
+
+Source the rapidenv and enter the rapid folder:
+
+```bash
+[opnfv@worker ~]$ source rapidenv/bin/activate
+(rapidenv) [opnfv@worker ~]$ cd rapid
+(rapidenv) [opnfv@worker rapid]$
+```
+
+Now we need `.env` , `.tst` and `machine.map` files to run the `runrapid.py` script that do the tests.
+
+Before creating theese files the IP of the generator pod is needed. On Node 1 run this command:
+
+```bash
+[opnfv@master ~]$ kubectl get pods -o wide
+NAME READY STATUS RESTARTS AGE IP NODE NOMINATED NODE READINESS GATES
+userspace-rapid-pod-t3-p1 1/1 Running 0 69m 10.244.1.157 worker <none> <none>
+userspace-rapid-pod-t3-p2 1/1 Running 0 69m 10.244.1.158 worker <none> <none>
+```
+
+For the `topology-3.env`:
+
+```
+[rapid]
+loglevel = DEBUG
+version = 19.6.30
+total_number_of_machines = 1
+
+[M1]
+name = rapid-pod-1
+admin_ip = 10.244.1.157
+dp_ip = 192.168.1.4
+dp_mac = de:ad:c3:52:79:9b
+
+
+[ssh]
+key=rapid_rsa_key
+user = root
+
+[Varia]
+vim = Openstack
+stack = rapid
+```
+
+Before the `.tst` file, the `prox.cfg` file should be copied under a folder in the same Node, in this case under `~/configs`.
+
+The `topology-3.tst`:
+
+```
+[TestParameters]
+name = Rapid_ETSINFV_TST009
+number_of_tests = 1
+total_number_of_test_machines = 1
+lat_percentile = 99
+
+[TestM1]
+name = Generator
+prox_launch_exit = false
+config_file = configs/prox.cfg
+dest_vm = 1
+mcore = [14]
+gencores = [15]
+latcores = [16]
+
+[test1]
+test=TST009test
+warmupflowsize=128
+warmupimix=[64]
+warmupspeed=1
+warmuptime=2
+imixs=[[64],[128],[256],[512],[1024],[1280],[1512]]
+flows=[1]
+drop_rate_threshold = 0
+MAXr = 3
+MAXz = 5000
+MAXFramesPerSecondAllIngress = 12000000
+StepSize = 10000
+```
+
+For `machine.map`:
+
+```
+[DEFAULT]
+machine_index=0
+
+[TestM1]
+machine_index=1
+
+[TestM2]
+machine_index=2
+
+[TestM3]
+machine_index=3
+
+[TestM4]
+machine_index=4
+```
+
+
+
+### Running the tests
+
+Now that it's all configured, the test can be started form the rapid folder with the `runrapid.py` script, passing the two files as arguments:
+
+``` bash
+(rapidenv) [opnfv@worker rapid]$ python runrapid.py --env topology-3.env --test topology-3.tst --map machine.map --runtime 10 --screenlog DEBUG
+```
