How to Use the Intel® Ethernet Controller XL710 Chip Backplane Image/Mode in Both, Dual 40G Mode and Dual 2x10G and/or 4x10G


Intel® Ethernet Controller XL710 chip RHEL*/CentOS 6 and 7 with an updated i40e driver


Onboard NIC Intel® Ethernet Controller XL710 configuration-related inquiry


How to ensure you have the correct NVM image loads and tools to accomplish backplane image/mode in both dual 40G mode and dual 2x10G and/or 4x10G


The Non-Volatile Memory (NVM) images we provide for our retail adapters do not change the port configuration. You may be able to use the Ethernet Port Configuration Tool, but there is no guarantee. Even if it could, it would be one (dual 40G mode) or the other (1x40 or 4x10G), but not simultaneously (no auto-negotiation with the switch, in other words).


This deals with changing operational modes on the Intel® Ethernet Controller X710-QDA1 and Intel® Ethernet Controller X710-QDA2.

To find out what each of the provided NVM images do, you can access the Possible port to physical lane configurations for various PHY interfaces section of the Intel® Ethernet Controller X710/XXV710/XL710 Datasheet. It has the possible configurations.

For a custom-design system with an onboard Intel® Ethernet Controller, a Field Application Engineer (FAE) could help, but this might require more information related to system integration.
