TL-SG2452 port keeps changing state up down
TL-SG2452 port keeps changing state up down
2017-11-05 08:03:51
Model : TL-SG2452

Hardware Version :

Firmware Version : 1.0.4 Build 20151127 Rel.67331(s)

ISP :

We're running diskless environment for 28 pc client,
as in any diskless setup, network is the most crucial part.
Our SMB traffic is quite high,
and the problem is, when the 28 client is fully used or almost full, some would get rebooted.
I'm not sure if this is related or not, but i'm getting this on my tp-link TL-SG2452

This log is not useful. That is mean some computers are rebooting, so port be changed from up tp down. In my opinion, if you start your computers one by one, maybe you will not meet this issue.
If you use managed software to power on all computers, you will meet these issue, is it right?

@cemara 

 

I have almost the same problem. But my ports goes down for few seconds. That makes me lose connection with my main server.

 

I have Build A = main server runing a 48 port swith connected via SFP to Build B = with have all the terminals connect to a 48 port switch. 

 

On Build B that occours the problem

 

as u can see on the log below

check this thread just for the advices, but I would say, you have a bit different problem, as your links are flapping once per about 10 minutes. Historically, TP-Link switches don't have hardware problem, but some software issues, like management hanging, wrong feature logic, etc. This link problem must be physical problem.
