interfaceType

The type of network interface. To create an Elastic Fabric Adapter (EFA), specify efa or efa. For more information, see Elastic Fabric Adapter for AI/ML and HPC workloads on Amazon EC2 in the Amazon EC2 User Guide.

If you are not creating an EFA, specify interface or omit this parameter.

If you specify efa-only, do not assign any IP addresses to the network interface. EFA-only network interfaces do not support IP addresses.

Valid values: interface | efa | efa-only
