Dear Vinícius Ferrão, 

Your Mellanox support case # 00320058/   has been updated By , with the following comment: 
/-------------------------------------------------------------
Hello Vinícius Ferrão,

Thank you for contacting Mellanox Technical Support.

1) DId you try changing switch ports when testing performance between two FreeBSD machines through switch?
2) What happens when you try a back-to-back connection between two FreeBSD machines? Do you get good results?
3) Did you test the performance between FreeBSD and a Linux machine through switch?

Please, follow the provided procedure in order to query your unmanaged switch: 
 
1) Download and install MFT (Mellanox Firmware Tool):
http://www.mellanox.com/content/pages.php?pg=management_tools&menu_section=34
Refer to the User Manual for the installation instructions:
http://www.mellanox.com/pdf/MFT/MFT_user_manual.pdf
 
2) From one of the nodes in the fabric, invoke: ibswitches.
Match the relevant switch GUID from the Mellanox switch label to the LID.
 
3) From one of the nodes in the fabric , invoke: mst start -> mst ib add -> mst status
 
4) Identify the relevant unmanaged switch mst representation based on the switch LID (from previous step 2).
* Matching the remote switch mst device representation to the relevant switch procedure:
Locate the switch in the "ibswitches" output and retrieve the switch LID. 
Convert the LID from Decimal to Hexadecimal base.
Locate the device with this LID (in hex base) from the "mst status" output. 

5) Invoke the following command, and provide the output:
flint -d <remote_switch_mst_device> q


We're looking forward to hearing from you.

Best regards,
Mellanox Technical Support
