Switch port LEDs blinking slow

    I have some strange undocumented behavior on a newly installed Aruba 1930 switch. 

    After connecting 2 LACP pairs, the status LED's of all connected ports started blinking slow (green, blinking every second, evenly). I can't find any explanation in the docs about this pattern. There is also nothing notable logged in the event log.

    - LACP ports are added to TRK 1 and set to LACP
    - Tried with and without loopback detection enabled
    - Status button is set to default (not set to PoE or SPD)
    - Traffic seems to be unaffected
    - I cannot find this specific blinking pattern in the docs
    - blinking starts after adding one of the LACP cables

    Any ideas ? Thanks!

    The LED blinking is definitely odd. It's so hit or miss what the LED does when there is traffic.
    In one internet speed test, the LED blinks slow during download but intermittently fast during upload.
    TCP Iperf tests between two hosts the LED only blinked slow, even at full 1Gbps speed.
    UDP Iperf tests between two hosts the LED blinked intermittenly fast during server to client, but slow during client to server.
    who knows at this point...

    Thanks for the video, that is exactly the same behavior as what I have been seeing myself!

    The same behavior here, and I don't know what happens either. What I need to solve here is that a switch is on v. 1.0.2 and the other in 1.0.3. As soon as I have availability I will go to v. 1.0.4 see if something changes, but from what came out in the release, the changes are practically insignificant

    Same behavior here on two switches with lacp and 1.0.4 version. Any idea why does It blink this way?

    Thanks.

    Seeing the exact same behaviour on a brand new 24 port non-poe switch, straight out of the box. No LACP or anything else has been configured.

    Any idea what could be the cause, or if it's something to be concerned about?

    Here's what I get. Does it look like the same pattern? Video from my post here: https://community.arubainstanton.com/communities/community-home/digestviewer/viewthread?MessageKey=a184de50-db4d-4667-a6ad-851c9a478d64&CommunityKey=84902a4b-1c23-44a8-8387-5ef7a53d4a4a&tab=digestviewer#bma184de50-db4d-4667-a6ad-851c9a478d64

    That's exactly what I'm seeing. I don't have any VLANs defined at the moment.
