Ethernet Port Configuration Tool (All Supported OSs)

Overview 

The 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:

• A reboot is required to apply configuration changes.
• 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 2x100Gbps, 2x50Gbps, or 1x100Gbps. One of the following methods may resolve the issue:
  
  • Use the utility to change the port option to 8x10Gbps; reboot your system; change to your originally desired configuration.
  • Completely power cycle your system.
• If the tool displays an error such as "Access error" or "Cannot initialize port," you may be using an outdated driver.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.
