high lately XS1930-10 randomly becomes unresponsive on all ethernet ports meaning it has to be power cycled to regain functionality. it feels like it could be faulty or I need to upgrade the firmware but would be nice to know if I am alone?

    Hi @boywiz,

    Generally, the loop guard is not activated on the uplink port or the ports that connect to other network devices. Instead, it is enabled mainly on the edge port.

    Hi @boywiz,

    May I clarify your symptoms?

    Was the switch not pingable? Or was the web GUI cannot access? Or was the traffics cannot be forwarded? Or was the port link down and cannot recover by replugging the cable?

    Hi thanks for getting back to me @Zyxel_Melen,

    so the power light is on but there is no activity on any of the ports even if I unplug them and plug them back in. even in ports that are not active, as I wondered if the port was being blocked or something.

    Hi @boywiz,

    Thank you for your feedback. However, the symptom is not yet clear to me. Could you please provide more information so that I may better clarify your problem?

    1. When you unplug the switch, did the link LED turn off? Or did it just keep on?
    2. Can you try to ping the switch? If yes, does the link LED blink?

    when i unplug the link led goes off

    the switch is not responding to pings, that is from something connected directly and from the uplink switch

    the light is static and shows no activity

    Hi @boywiz,

    Thanks for the information. May I know the frequency of this problem? Also, could you help to access the switch web GUI to collect the tech support for me to check? The path is Maintenace > Tech-support > all to download. And please provide it to me via private message.

    If the web GUI is inaccessible, please press the reset button (not the restore button) to reboot the switch to collect.

    Hi @boywiz,

    Thanks for the tech support.

    I discovered that switch ports 7 and 8 were linked down due to the loop guard. Upon checking your configuration, I noticed that ports 7 and 8 were set as LAG and had loop guard enabled. Kindly advise you to check if there's a loop that occurred on the LAG connecting device.
