Alternatively, one can use a script provided in the ixgbe driver that will map queue 0 to core 0, queue 1 to core 1 etc. Instead, proceed to this procedure: These drivers are only supported as a loadable module at this time.

You can check the systemd or udev versions on RPM-based systems with the following command:. If another instance boots with this file, the operating system will be unable to find the device and eth0 might fail, causing boot issues.

The MSI-X interrupts in Linux as of the time this document is written are assigned randomly which means that each queue will deliver packets to a random core. For more information, see Accessing Amazon EC2.

Updating kernels and kernel modules, as well as enabling the sriovNetSupport attribute, might render incompatible instances or operating systems unreachable; if you have a recent backup, your data will still be retained if this happens. Systems that use systemd or udev versions or greater can rename Ethernet devices and they do not lihux that a single network interface will be named eth0. Firmware on network controller is ROM based and generally speaking not upgradable.

For more details how to set the SMP affinity please see this white paper mentioned before. Sign In to the Console.

Amazon EC2 provides enhanced networking capabilities through the Intel VF interface, which uses the Intel ixgbevf driver. To enable enhanced networking instance store-backed instances. To prepare for enhanced networking using the Intel VF interface, set up your instance as follows:.


For more information, see How do I enable and configure enhanced networking on my EC2 instances? If you plug in a different type of module, the driver will not 8259.

This behavior can cause problems connecting to your instance. From your local computer, reboot your instance using the Amazon EC2 console or one of the following commands: To check whether an instance has the enhanced networking sriovNetSupport attribute set, use one of the following commands:.

Compile and install the ixgbevf module on your instance. Try installing the version of the ixgbevf module included with the distribution of Linux for your instance. For questions related to hardware requirements, refer to the documentation supplied with your adapter.

Please refer to your browser’s Help pages for instructions. Through SMP affinity the user can define re-assign the interrupts and choose themselves libux queue to bind to each core. To enable enhanced networking instance store—backed instances. We strongly advise you to read this white paper in order to see some pointers that are important in developing networking applications.


Only single speed, 10 gigabit modules are supported. Determine if your system uses predictable network interface names by default. From your local computer, enable the enhanced networking attribute using one of the following commands:. Another story is Option ROM upgrade, which is sometimes mistakenly called firmware it is not a firmware as it executes on host system, not on ASIC itself.

To check whether an AMI already has the enhanced networking sriovNetSupport attribute set, use one ilnux the following commands:.

In the above case, the ixgbevf module is not loaded, because the listed driver is vif.

Before you begin, check if enhanced networking is already enabled on your instance. There is no way to disable the enhanced networking attribute after you’ve enabled it.
