I have purchased the card (AOC-SG-I4) from Supermicro in the UK who have passed this buck to Intel.
I have installed the card, on a Microsoft 2003 server with the latest drivers (15.3) and a Netgear GS724T switch.
I have an application which is using the Microsoft FTP client software to communicate with a web based FTP server, this application works correctly when I have not created any team
When I create a SLA team I get a communication error with the FTP server.
Does anyone know if there is a fix for my problem or a configuration setting that I can try ?
I had configured the switch for a Link Aggregated Group, the team switch test accepted the configuration was correct for the team.
I had configured Static Link Aggregation.
The problem may be due to the way FTP works via the command interpreter, HTML FTP works correctly.
It is not a special application, I can test the from a command prompt, by connecting to an external ftp server.
Once I have connected and logged on, I issue a dir command and the session freezes.
I can sometimes get a 425 error if I close the session via the red cross
This souds suspicously like a firewall issue on your server. I'm not a FTP expert, however if memory serves when you login it uses one 'sesson' or port and then after that everything else (like doing a dir etc.) is over another port.
.. just did a search and found an article that looks just like what you are experiencing:
Maybe take a look at this and see if helps you out.
Thanks for that info, I have not been able to test it yet - I will do as soon as possible.
There is no firewall involved and FTP is in active mode, which would suggest that the initial request is using 1 member of the team and being returned through another member of the team and being rejected.
That was my 1st thought as well, however you indicated that the switch was also properly configured, in which case the traffic would only be passed from the switch on a single port. From a swtich/ethernet controller perspective there is no difference between FTP traffic or HTTP etc. Which is what leads me to believe this is likely an app or OS level challenge.
I believe the article I referred to suggested putting ftp in passive mode and see if that works. I look forward to hearing your results.
I suspect that it is at OS level, I will hopefully be able to test sometime next week - once I have arranged some downtime at my clients site.
I will be able to test the passive mode FTP, I have been informed that the customer's FTP client software only works in active mode.
