• Lets follow the steps provided in the ONOS tutorial [2]

• Hints/Tips/Watchout:
  • Clicking on "reset" just resets ONOS. You will have to then click on "ONOS Gui" icon or "ONOS" icon to open a console into ONOS
    • Sometimes, clicking on "ONOS" icon does not launch anything. You will have to retry or try starting the "ONOS Gui" first and then the "ONOS" terminal.
    • Before the part starting with "flows commands", reactivate the onos app so that ping can work
    • When you do the last part, i.e. the GUI part, try to remove links (in mininet) and bring them back on and see the changes in the GUI
