Dear Vin=C3=ADcius Ferr=C3=A3o,=20 Your Mellanox support case # 00320058/ has been updated By , with the fol= lowing comment:=20 /------------------------------------------------------------- Hello Vin=C3=ADcius Ferr=C3=A3o, Thank you for contacting Mellanox Technical Support. 1) DId you try changing switch ports when testing performance between two F= reeBSD 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 swit= ch:=20 =20 1) Download and install MFT (Mellanox Firmware Tool): http://www.mellanox.com/content/pages.php?pg=3Dmanagement_tools&menu_sectio= n=3D34 Refer to the User Manual for the installation instructions: http://www.mellanox.com/pdf/MFT/MFT_user_manual.pdf =20 2) From one of the nodes in the fabric, invoke: ibswitches. Match the relevant switch GUID from the Mellanox switch label to the LID. =20 3) From one of the nodes in the fabric , invoke: mst start -> mst ib add ->= mst status =20 4) Identify the relevant unmanaged switch mst representation based on the s= witch LID (from previous step 2). * Matching the remote switch mst device representation to the relevant swit= ch procedure: Locate the switch in the "ibswitches" output and retrieve the switch LID.= =20 Convert the LID from Decimal to Hexadecimal base. Locate the device with this LID (in hex base) from the "mst status" output.= =20 5) Invoke the following command, and provide the output: flint -d <remote_switch_mst_device> q We're looking forward to hearing from you.
