Describe instances

For information about ENA Express configuration for specified instances, run the describe-instances command in the AWS CLI, as follows. This command example returns a list of ENA Express configurations for the network interfaces attached to each of the running instances that are specified by the --instance-ids parameter.

[ec2-user ~]$ aws ec2 describe-instances --instance-ids i-1234567890abcdef0 i-0598c7d356eba48d7 --query 'Reservations[*].Instances[*].[InstanceId, NetworkInterfaces[*].Attachment.EnaSrdSpecification]'[
	[
		[
			"i-1234567890abcdef0",
			[
				{
					"EnaSrdEnabled": true,
					"EnaSrdUdpSpecification": {
						"EnaSrdUdpEnabled": false
					}
				}
			]
		]
	],
	[
		[
			"i-0598c7d356eba48d7",
