Aruba 2930 Openflow reboot

    Posted May 02, 2023 12:13 PM

    Dear all,
        we are testing openflow 1.3 functionalities of Aruba 2930f and we have find out that after a reboot or a switch power outage all the flows disappears from the pipeline.

    Is it possible to have persistent flows in the switch?

    Regards.

    Aldo.

    I think the idea of Openflow is that the flow table lives in memory only, and should be retrieved from the controller as soon as the switch reboots.
    I'm not sure what you try to do, as I don't see a lot openflow in use anymore lately.

    Thanks for your support, we are tring to reprogram the behavior of IoT networks, we thing that easy re-programmable features are necessary in complex networks and we do not see any other technology other than openflow that con gives us a standard configuration, obviously must be reliable otherwise it is meaningless.

    If you have any advices, are very welcome.

    Aldo.

    I think the answer is that you can't let the openflow table survive a reboot, probably by design as the table contents is in-memory only.

    If you need a confirmation, please work with Aruba Support.
