This tab covers how to find information about your current ENA Express settings in the AWS Management Console.

This tab covers how to find information about your current ENA Express settings in the AWS CLI.

Describe instances

For information about ENA Express configuration for specified instances, run the describe-instances command 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",
			[
				{
					"EnaSrdEnabled": true,
					"EnaSrdUdpSpecification": {
						"EnaSrdUdpEnabled": false
					}
				}
			]
		]
	]
]

Describe network interfaces

For information about ENA Express settings for a networking interface, run the describe-network-interfaces command as follows:

[ec2-user ~]$ aws ec2 describe-network-interfaces
{
"NetworkInterfaces": [
{
	"Association": {
		....IPs, DNS...
	},
	"Attachment": {
		"AttachTime": "2022-11-17T09:04:28+00:00",
		"AttachmentId": "eni-attach-0ab1c23456d78e9f0",
		"DeleteOnTermination": true,
		"DeviceIndex": 0,
		"NetworkCardIndex": 0,
		"InstanceId": "i-1234567890abcdef0",
		"InstanceOwnerId": "111122223333",
		"Status": "attached",
		"EnaSrdSpecification": {
			"EnaSrdEnabled": true,
			"EnaSrdUdpSpecification": {
				"EnaSrdUdpEnabled": true
			}
		}
	},
	...
	"NetworkInterfaceId": "eni-1234567890abcdef0",
	"OwnerId": "111122223333",
	...
}

}

This tab covers how to find information about your current ENA Express settings using PowerShell.

Describe network interfaces

For information on ENA Express settings for a networking interface, run the Get-EC2NetworkInterface Cmdlet with the Tools for PowerShell as follows:

PS C:\> Get-EC2NetworkInterface -NetworkInterfaceId eni-0d1234e5f6a78901b | `
Select-Object `
    Association, 
    NetworkInterfaceId, 
    OwnerId, 
    @{Name = 'AttachTime'; Expression = { $_.Attachment.AttachTime } },
    @{Name = 'AttachmentId'; Expression = { $_.Attachment.AttachmentId } },
    @{Name = 'DeleteOnTermination'; Expression = { $_.Attachment.DeleteOnTermination } },
