Setting up EFA-Enabled Security Group

An Elastic Fabric Adapter (EFA) is a network device that can attach to an AWS EC2 instance to accelerate machine learning applications. EFA requires a security group that allows all inbound and outbound traffic to and from the security group itself. Follow the instructions in Prepare an EFA-enabled security group for more details.

The image below is an example of adding an inbound and outbound rule allowing “All Traffic” through the associated security group.
