#### [ AWS CLI ]

**To get the ENA Express settings for an instance**  
Use the [https://docs.aws.amazon.com/cli/latest/reference/describe-instances.html](https://docs.aws.amazon.com/cli/latest/reference/describe-instances.html) command. 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.

```
aws ec2 describe-instances \
    --instance-ids i-1234567890abcdef0 i-0598c7d356eba48d7 \
    --query 'Reservations[*].Instances[*].[InstanceId, NetworkInterfaces[*].Attachment.EnaSrdSpecification]'
```

The following is example output.

```
[
    [
        [
            "i-1234567890abcdef0",
            [
                {
                    "EnaSrdEnabled": true,
                    "EnaSrdUdpSpecification": {
                        "EnaSrdUdpEnabled": false
                    }
                }
            ]
        ]
    ],
    [
        [
            "i-0598c7d356eba48d7",
            [
            {
                    "EnaSrdEnabled": true,
                    "EnaSrdUdpSpecification": {
                        "EnaSrdUdpEnabled": false
                    }
                }
            ]
        ]
    ]
]
```

**To get the ENA Express settings for a network interface**  
Use the [https://docs.aws.amazon.com/cli/latest/reference/describe-network-interfaces.html](https://docs.aws.amazon.com/cli/latest/reference/describe-network-interfaces.html) command.

```
aws ec2 describe-network-interfaces \
    --network-interface-ids eni-1234567890abcdef0 \
    --query NetworkInterfaces[].[NetworkInterfaceId,Attachment.EnaSrdSpecification]
```

The following is example output.

```
[
    [
        "eni-1234567890abcdef0",
        {
            "EnaSrdEnabled": true,
            "EnaSrdUdpSpecification": {
                "EnaSrdUdpEnabled": false
            }
