NIC Times Out After About 15 Seconds Of Inactivity

[mhaneyit]

I have a UPS that seems to timeout every 15 seconds or so. The switch will show the port go down every 15 seconds or so and then come back up after about 5 seconds. If you are logged into the UPS and are inactive for about 15 seconds and then try to navigate to a different screen it will lag or give an error and then after about 5 seconds or so it will start responding again.

I found if I ran a continuous ping to its IP the port wouldn't show it drop and it wouldn't hang up while you were logged in and inactive. Also, as long as you stayed active while logged in (changed screens every few seconds), without the ping running, it also wouldn't drop.

I tried hard setting the speed/duplex to 100 Full on the NIC and the switch port, as I saw a post where someone else said that might help, but it still drops.

The switch log is completely full of these port flapping events, since it happens every 15 seconds or so. And I am constantly getting alerts for the device going into ping failure.

Anyone seen this before or have any recommendations?

Hi @mhaneyit,

Could I ask you to raise a case for this with your local support?  I'd really like to see the debug logs from the card, but that works better over a ticket than the forums, so we can keep any identifying data off the public forums.

If you have any problems at all getting traction, feel free to send me the case number on here and we can make sure the ticket's getting the attention it needs.

Thanks,

  Shaun
