Intel(R) Ethernet Port Configuration Tool ========================================= October 11, 2019 Contents ======== - OVERVIEW - SUPPORTED OPERATING SYSTEMS - RUNNING THE UTILITY - OPTIONS - BASIC USAGE EXAMPLE - EXIT CODES - CUSTOMER SUPPORT - LEGAL OVERVIEW ======== The Intel(R) Ethernet Port Configuration Tool (EPCT) is a command line utility that allows users to change the link type of a device. The supported types are defined within the adapter's NVM. This utility displays only the devices that potentially support reconfiguration. NOTE: An immediate reboot is required to apply configuration changes. On systems running Oracle* Solaris* 11, you must perform a full reboot, not a fast reboot. NOTE: You may lose link if you change the link type of your device from any port option that contains three to seven ports to a port option that enables multi-lane interfaces, such as 2x100G, 2x50G or 1x100G. One of the following methods may resolve the issue: - Use the utility to change the port option to 8x10G; reboot your system; change to your originally desired configuration. - Completely power cycle your system. NOTE: If the tool displays an error such as "Access error" or "Cannot initialize port" you may be using an outdated driver. Please download the latest driver from https://support.intel.com and try again. Supported Operating Systems --------------------------- Microsoft Windows Server* 2008 R2 and later Linux* Kernel 3.x/4.x and later Red Hat* Enterprise Linux* 6.10 and later SUSE* Linux Enterprise Server 12 SP4 and later UEFI 2.3 and later Oracle* Solaris* 11 VMWare* ESXi* 6.0 and later FreeBSD 12 and later Notes: - On systems running Linux, FreeBSD, Solaris, or ESXi, the base driver must be present for EPCT to function correctly. RUNNING THE UTILITY =================== Using the "/?" option will display a list of supported command line options. NOTE: The utility must be run with root/administrator privileges. OPTIONS ------- The Intel(R) Ethernet Port Configuration Tool can be run with any of the following command line options. NOTE: The slash '/' character can be used in place of the dash '-' character. NOTE: All options are case-sensitive. -h -help -? Displays command line help. -h (parameter) -help (parameter) -? (parameter) Displays help for the specified parameter. - devices [branding] Displays supported devices present in the system. If 'branding' is specified, then the branding view is displayed. -nic=(device_index) Selects the device at the specified index. -get Displays port configuration for the device specified by -nic. -set (option) Configures the selected device with the specified option. The option string is defined as: QxPxS - if all port speeds are the same across both quads and all lines, or P1xS1-P2xS2 - if each quad has a specific speed, or P11xS11+<...>+P1nxS1n-P21xS21+<...>+P2mxS2m Where: Q - The desired quad number P - The desired port number S - The desired port speed n - The desired port/speed combination for quad 0 m - The desired port/speed combination for quad 1 NOTE: An immediate reboot is required after changing the port settings. Basic Usage Examples ==================== The following examples show the tool's -devices option, the -get option, and the -set option. -devices -------- >epct -devices NIC Seg:Bus:Fun Ven-Dev Connector Ports Speed Quads Lanes per PF === ============= ========= ========= ===== ======== ====== ============ 1) 000:012 8086-1583 QSFP 2 50 Gbps Single 1 2) 000:015 8086-1584 QSFP 4 25 Gbps Single 1 3) 000:017 8086-1589 SFP 4 25 Gbps Single 1 4) 000:030:00-01 8086-1588 QSFP 2 25 Gbps Single 1 000:030:02-05 8086-1587 QSFP 4 10 Gbps Single 1 >epct -devices branding NIC Seg:Bus Ven-Dev Mode Adapter Name === ======= ========= =========== ============================================= 1) 000:012 8086-1583 N/A Intel(R) Ethernet Converged Network Adapter XL710 2) 000:029 8086-1583 4x10 Intel(R) Ethernet Converged Network Adapter XL710 3) 000:129 8086-1599 2x25,2x10- Intel(R) Ethernet Controller E810-XXV for 2x10 backplane 4) 000:132 8086-159A 2x50 Intel(R) Ethernet Controller E810-XXV for QSFP -get ---- >epct -nic=1 -get Available Port Options: ========================================================================== Active Port Quad 0 Quad 1 Option Option (Gbps) L0 L1 L2 L3 L4 L5 L6 L7 ======= ============================= ================ ================ 4x25 -> 25 25 25 25 - - - - 2x1x100 -> 100 - - - 100 - - - X 2x2x25 -> 25 25 - - 25 25 - - 2x50 -> 50 - 50 - - - - - 2x1x50 -> 50 - - - 50 - - - 2x4x10 -> 10 10 10 10 10 10 10 10 2x25+2x10-2x10 -> 25 25 10 10 10 10 - - 1x10+1x25+1x10+1x25-2x10 -> 10 25 10 25 10 10 - - -set ---- Set two ports to 50 Gbps.

Exit Codes ========== Upon exit, when possible, the EPCT reports an overall status code to indicate the results of the operation. In general, a non-zero return code indicates an error occurred during processing. Value Description 0 Success. 1 No supported adapter found. 2 Insufficient privileges to run the tool. 3 No driver available. 4 Unsupported base driver version. 5 Bad command line parameter. 6 Invalid adapter selected. 7 Unsupported ports configuration selected. 8 Adapter does not support ports configuration. 9 Memory allocation error. 10 Adapter access error. INSTALLATION ============= Installing the tool on Microsoft* Windows* ------------------------------------------ To install the tools' drivers on Windows, run install.bat from the appropriate directory of the install package. Although the tool are not installed with install.bat, the driver that the tool requires is copied into the local machine Windows driver directory. To run the tool, launch a Command Prompt window from the Windows Start Menu. Go to the media and directory where the tool is located and run the utility. The readme files for each tool are found in the same directory as the tool. These tools can be manually installed on the local hard drive in any directory. The tool uses its own driver file (not the same as the system network driver). If the driver sys file already exists in the drivers directory, install.bat may fail to copy. Using the /y switch with install.bat will override and copy the driver file regardless. However, this can be dangerous if an older version of the driver is being used by another application such as Intel(R) PROSet for Windows Device Manager. If a driver is already present in the drivers directory, try running the tool from the command prompt. If it runs, then the driver is fine. The tool will not run if the driver version present does not match the driver version expected. Note that you must have access to the %systemroot%\system32\drivers directory. Only the administrator account has these privileges. You must be logged in as administrator or the tools must be run as administrator. Note that on Windows, any device that is disabled in device manager will not be accessible by tools due to no memory resources. You would get an error code 0xC86A800E. To solve this problem, you can do one of the following: 1) Re-enable the device in device manager. Never disable this device when using tools. 2) Install an NDIS device driver for the device and make sure that it does not have a yellow or red bang by it in device manager. 3) Delete the device from device manager and restart the system. The install new hardware wizard should appear on next reboot. Do not cancel this. Just move the window aside and run the tool(s). Generally, you can click "cancel" on the wizard but there are some cases where Windows will disable the memory resources causing you to get back into the same state. Installing the tool on EFI -------------------------- The EFI 1.x tools are not supported in this release. There is no installation required for EFI tools. The tools can simply be copied from the appropriate directory to the drive that they will run from. The EFI2 binaries are for use with the UEFI Shell 2.X with the UEFI 2.3 HII protocol. EFI2 tools will not run on the EFI Shell 1.X or if the UEFI 2.3 HII protocol is not present. Note that while EFI supports USB drives, there may be issues running tools from the USB drive. Whether or not there are issues are BIOS specific. If you experience issues, run the tool from hard disk instead. Installing the tool on Linux* ============================= In order to run this tool on Linux*, the base driver must be installed on the system. INSTALLING THE TOOL ON VMWare* ESXi* =================================== In order to run this tool on VMWare* ESXi*, the base driver must be installed on the system. INSTALLING THE TOOL ON FreeBSD* =============================== In order to run this tool on FreeBSD*, the base driver must be installed on the system.
