Going down for few seconds and turn up again. This's making my Hospital OS to fall.

 

Is something missing ? 

I checked all the cables. They'r fine. All cables are cat 6 and they'r not runing with other wires.

 

Can't find any solution yet.

 

Can someone help me please.

You have 3 options here:

1. It is a problem with the cables. Take you laptop, go to the switch, try your new patchcord into the laptop. Also try to run cable diagnostic on your switch to check pairs in your cable.

2. It is a problem with device, which is connected to the switch. What is connected there? Try to connect your laptop instead and check.

3. It is a problem with ports on the switch. Try to reset your switch, upgrade firmware, if it is not the newest one. If nothing helps, go to service-center.

1- All cables are fine. I tested em all.

2- it's all computer terminals. Brand new.

3- Could be, since it came with some ports blocked like SFP ones. I'll try to upgrade my firmware.

 

Did you see the log, it lose the connection for about 1-2 seconds.

Yeah, I see, but firstly it is about 9 minutes of normal link up. I myself only expierenced something like you before, when I had problems with cables or connected devices network cards. Never switch was a key. Usually, if you have problem with the port on switch, you have much more chaotic logs, broadcast/multicast storms on port, etc. Switch can't usually work normally.

What do you mean "ports blocked"? SFPs have black cap from the box, which close ports.

Not the caps LOL. Something to do with the system. A friend of my told me that it came with some kind of block on Sfp ports. But he fixed. 

 

Well, I just did the Upgrade on the firmeware. I'll see if it goes down and up again.

I don't know then. This switch doesn't even have any SGMII mode on SFP-ports, it only has Auto/Full duplex mode, which can affect somehow to the meaning of "block sfp ports". Hard reset should fix all the software unknown stuff.

If you are sure about cables and end-devices, unfortunately, it seems to be broken then. Nothing you can do from your side.

Backup, hard-reset via button, laptop + 1m cable. Still problem -> 100% broken.

 

P.S. Btw, try 10M/Half duplex on problem ports and check. If no link flaps, it is cable or NIC still:)

I even tried to make cable diag with a 4pin wire, but I still have all 4 pairs in output. It seems like your ports are really broken.

@Mitya 

 

So, should I swap ports and try again?

 

My switch still on warranty I may ask to swap divices.

I would swap the switch, if it is on warranty.
