Virtual LoadMasters deployed within the AWS Cloud now support 10 Gbps throughput interfaces. This support comes with a few limitations:

  • Link on the single logical ENA interface cannot be detected through the OS, so ‘No Link’ will be displayed when the interface status is queried via the API or displayed in the UI.
  • Interface Graphs for 10 GB interfaces on the statistics page are displayed incorrectly. This will be addressed in a future release.

If you upgrade from a release prior to 7.2.48 to 7.2.48 or a later release and your AWS VM is running a virtual machine instance type that does not support 10 GB interfaces (e.g., “m4.10xlarge"), you must convert the VM to a machine type that supports 10 GB interfaces (e.g., "m4.16xlarge) to enable 10 GB interfaces on LoadMaster. Following these steps:

  • Shut down LoadMaster using the LMOS UI or API.
  • Enable ENA driver support on the AWS virtual machine:
    aws ec2 modify-instance-attribute --instance-id instanceID --ena-support
  • Change the AWS virtual machine instance type to one that supports the ENA 10 GB driver (e.g., m4.16xlarge) using the AWS UI.
  • Start the LoadMaster VM.
