Падение скорости SLM2008

[Ervandyan]

Здравствуйте, у меня 2 свитча  SLM2008

Только на одном через несколько часов работы падает скорость, подключено 3 компьютера на скорости 1гбит и роутер на скорости 100мбит, скорость с 1гбита падает до 5мбит, при этом соединение показывает 1гбит. Помогает только перезагрузка свитча, потом снова через несколько часов такая же ситуация.

Прошивка Current Firmware Version: 2.0.0.10

Пробовал перепрошивать, сбрасывать на заводские установки, ничего не помогло.

Подскажите пожалуйста как исправить?

Вот тесты до и после перезагрузки свитча

Hi

After looking at the iperf data, it sure indicates a problem with traffic between the two switches or maybe within a switch.. 

The exact cause of this traffic problem is undetermined at this stage, needs further analysis...

Do we enable flow control, what is the autonegotiated speed of the ethernet port, what do the port statistics look like.  these are all questions that should be looked into.

It would have been be interesting to see a wireshark capture going to IP host at 192.168.1.2 at times when throughput is low. and a capture when throughput was good.  These captures only need to be a few seconds in long.

Might I suggest that you contact your local Small Business Support Center who can assist in hopefully identifying your issue.

I have copied the worldwide support contact information URL below for your referenece.
