Step 1: Verify if the ENA is already enabled on the EC2 Instance by running the below command:
aws ec2 describe-instances --instance-ids INSTANCEID --query "Reservations[].Instances[].EnaSupport"
If ENA is not enabled, there will be no output from the above command.
Step2: Stop the EC2 Instance.
Step3: From your local computer, run the below command to enable ENA.
aws ec2 modify-instance-attribute --instance-id INSTANCEID --ena-support
Step4: Verify to make sure the ENA is enabled.
aws ec2 describe-instances --instance-ids INSTANCEID --query "Reservations[].Instances[].EnaSupport"
If ENA is enabled, the output will be ‘True’.
Step5: Start the EC2 Instance.
