This is an archive of the ONOS 1.2 wiki. For the current ONOS wiki, look here.

This quick tutorial will walk you through the launch of the controller, cli and mininet, all contained within the pre-built VM. 

  1. Download SPRING-OPEN VM here: http://downloads.onosproject.org/spring-open/SPRING-OPEN.ova
  2. Use VirtualBox to import and run the SPRING-OPEN VM.

  3. From a terminal on your host machine, use ssh to login to the VM using the following username (mininet) and password (mininet). Yes, it is a Mininet VM where we have loaded other stuff, which is why the username@host will show up as 'mininet@mininet-vm'. Of course, you have to replace the ip-address shown below '10.1.9.125' with the IP address assigned to the VM during startup.

    $ ssh -X mininet@10.1.9.125
mininet@10.1.9.125's password:

drwxr-xr-x 10 mininet mininet    4096 Feb 20  2014 zookeeper-3.4.6
mininet@mininet-vm:~$

  4. Pull the latest controller code. When pulling code, another screen may pop up declaring a merge operation – just hit Control-X to get rid of it.

    mininet@mininet-vm:~$ cd spring-open
mininet@mininet-vm:~/spring-open$ git pull

  5. Make sure that the network-configuration file to be loaded on the controller says 'sr-ecmp10-demo.conf' — see the last line below

    mininet@mininet-vm:~/spring-open$ cat conf/onos.properties 
floodlight.modules = net.floodlightcontroller.core.FloodlightProvider,\
net.floodlightcontroller.threadpool.ThreadPool,\
net.onrc.onos.core.topology.TopologyPublisher, \
net.onrc.onos.core.datagrid.HazelcastDatagrid,\
net.onrc.onos.core.flowprogrammer.FlowProgrammer,\
net.onrc.onos.core.intent.runtime.PathCalcRuntimeModule,\
net.onrc.onos.core.intent.runtime.PlanInstallModule,\
net.onrc.onos.core.registry.ZookeeperRegistry, \
net.onrc.onos.core.metrics.OnosMetricsModule, \
net.onrc.onos.apps.websocket.WebSocketModule, \
net.onrc.onos.core.main.config.DefaultConfiguration, \
net.onrc.onos.apps.segmentrouting.SegmentRoutingManager
net.floodlightcontroller.restserver.RestApiServer.port = 8080
net.floodlightcontroller.core.FloodlightProvider.openflowport = 6633
net.floodlightcontroller.core.FloodlightProvider.workerthreads = 16
net.floodlightcontroller.core.FloodlightProvider.cpqdUsePipeline13 = true
net.floodlightcontroller.forwarding.Forwarding.idletimeout = 5
net.floodlightcontroller.forwarding.Forwarding.hardtimeout = 0
net.onrc.onos.apps.websocket.WebSocketModule.port = 8081
net.floodlightcontroller.core.FloodlightProvider.cpqdUsePipeline13 = true
# NOTE: Do NOT modify or remove the line below. This value will be overwritten by onos.sh script.
net.onrc.onos.core.datagrid.HazelcastDatagrid.datagridConfig = 
# Uncomment and list all the ZooKeeper instances after localhost on multi-instance deployment.
#net.onrc.onos.core.registry.ZookeeperRegistry.connectionString = localhost:2181,otherhost:2181
# Specify a network configuration file to be used by the NetworkConfigManager
net.onrc.onos.core.configmanager.NetworkConfigManager.networkConfigFile = conf/sr-ecmp10-demo.conf

  6. Run the SPRING-OPEN version of the ONOS controller

    mininet@mininet-vm:~/spring-open$ ./onos.sh start
Starting ZooKeeper ... ls: cannot access /home/mininet/spring-open/onos-logs/zk.mininet-vm.log*: No such file or directory
JMX enabled by default
Using config: /home/mininet/spring-open/conf/zoo.cfg
Starting zookeeper ... STARTED
Starting ONOS controller ...  STARTED

    You can check if the controller is running correctly as following

    mininet@mininet-vm:~/spring-open$ ./onos.sh status
[ZooKeeper]
JMX enabled by default
Using config: /home/mininet/spring-open/conf/zoo.cfg
Mode: standalone
[RAMCloud coordinator]
0 RAMCloud coordinator running
[RAMCloud server]
0 RAMCloud server running
[ONOS core]
1 instance of onos running

  7. You can watch the controller logs if you wish

    mininet@mininet-vm:~/spring-open$ tail -f onos-logs/onos.mininet-vm.log
2014-12-04 18:03:48,435 DEBUG [main] n.f.c.i.Controller [Controller.java:832] OFMessageListeners for FLOW_REMOVED: planInstall,

  8. Open another terminal to run Mininet

    mininet@mininet-vm:~$ cd mininet/
mininet@mininet-vm:~/mininet$ cd custom/
mininet@mininet-vm:~/mininet/custom$ sudo ./testEcmp_10sw.py

  9. On another terminal run the SPRING-OPEN CLI

    mininet@mininet-vm:~$ cd spring-open-cli/
mininet@mininet-vm:~/spring-open-cli$ source ./workspace/ve/bin/activate
(ve)mininet@mininet-vm:~/spring-open-cli$ sudo make start-sdncon
if ! lsof -iTCP:8000 -sTCP:LISTEN >/dev/null; then \
	( \
	  cd /home/mininet/spring-open-cli/sdncon; \
	  [ -d /home/mininet/spring-open-cli/workspace/ve/cassandra/data/sdncon ] || python manage.py syncdb --noinput; \
	  /home/mininet/spring-open-cli/build/start-and-wait-for-port.sh -p 8000 -l /home/mininet/spring-open-cli/workspace/ve/log/sdncon.log python manage.py runserver 0.0.0.0:8000; \
	); \
	fi

  10. Check if all the switches are connected to SPRING-OPEN controller using the controller CLI.

    mininet-vm# sh switch 
#  Switch DPID             Alias        Connected Since              Connected At    Type   Controller

  11. Test connections in mininet

    mininet> pingall
*** Ping: testing ping reachability
h1 -> h2 h3 h4 
h2 -> h1 h3 h4 
h3 -> h1 h2 h4 
h4 -> h1 h2 h3 
*** Results: 0% dropped (12/12 received)
  12. Done. Here are some things you could do next:
    • See the prototype videos for features you could try. 
    • You can replicate the prototype shown in the videos using Software switches in the VM you just used in this Getting Started tutorial. See how in the Configuration section of the User Guide - you would need to configure the controller AND the software switches.
    • You can also try to replicate the prototype (or build your own prototype) with hardware switches. See how in the Installation Guide.
