  • Hosts are not communicating? Do you have at least two interfaces configured and two hosts attached - using the same VLAN Id?

  • Is your configuration correct? Has it been correctly parsed? The first step is to checked if the configuration has been parsed and correct running at the ONOS CLI the command "interfaces". This should give you a list of interfaces configured in the system

  • Any exception? Type log:exeption-display in the ONOS CLI  to discover it.

  • Are hosts connected to your OpenFlow data plane? I a host start to send out packets into the OpenFlow network you should be able to see it, even if VPLS is not installed yet or no configuration is provided. Go in the ONOS CLI and type "hosts". As result, you should see something similar to this (100, 2000, 300 in this case are the VLAN Ids used):

    Please, note that you should see results only for hosts that already sent traffic into the Network. This doesn’t happen for example with Mininet, where hosts are only processes without any application running by default.
