GS324TP S350 SFP Port deactivates after 30 seconds to 2 hours
Dear Community, I have a Netgear GS324TP in use as main switch for my home. It is running fine for two years now. Recently I have switched my router to a Ubiqity Dreambox Pro and connected th...
It seems that there is a compatibility issue between the Ubiquity Dreambox Pro and the GS324TP because if you are using your old router with the GS324TP, it works just fine.
I suggest you to set up port mirroring on the GS324TP switch. Select the SFP port (that is connected to the Ubiquity Dreambox Pro) as the source port on the GS324TP switch. Then, select another ethernet port as the destination port on the GS324TP switch where a PC (installed with Wireshark) is directly connected. Run Wireshark and observe. It would be best that Wireshark would be able to capture what happens in the source port (wait for the connection to go down as you have stated in your initial post). The moment that the issue happens, stop Wireshark and save the packet capture.
Note: You can get another packet capture but this time, use the ethernet port (that is connected to the Ubiquity Dreambox Pro) as the source port since you mentioned that the issue also occurs using the normal ports.Kindly read pages 319-321 of the GS324TP user manual here on how to set up port mirroring. You may download Wireshark here. As reference, check this link I found online on how to use Wireshark.
For the captured packets to be analyzed, kindly open a chat or online support ticket with NETGEAR Support here and attach the captured packets from Wireshark for it to be analyzed by the NETGEAR Support team as well as state your concern.

Hi DaneA,
thank you so much for your great support. I have setup the mirroring however I have found the issue before using it. Indeed it was neither the GS324TP nor the Dreambox but a defect LAN cable that caused the issues.
The cable was used to connect an access point directly to the Dreambox.
I never expected a defect cable could crush the whole network. Well I guess you never stop learning.
Thanks again and see you.
Kind regards
