# Files d’attente ENA
<a name="ena-queues"></a>

Les files d’attente ENA sont allouées aux interfaces réseau avec des limites statiques par défaut basées sur le type et la taille de l’instance. Sur les types d’instances pris en charge, vous pouvez répartir ces files d’attente de manière dynamique entre les interfaces réseau Elastic (ENI). Bien que le nombre total de files d’attente par instance dépende de son type et de sa taille, vous pouvez configurer plusieurs ENI avec des files d’attente ENA jusqu’à atteindre le nombre maximum de files d’attente pour l’ENI et l’instance.

L’allocation flexible des files d’attente ENA optimise la distribution des ressources, permettant ainsi une utilisation maximale du vCPU. Les charges de travail à hautes performances réseau nécessitent généralement plusieurs files d’attente ENA. Vous pouvez optimiser les performances du réseau et le nombre de paquets par seconde (PPS) en ajustant le nombre de files d’attente en fonction de vos besoins spécifiques en matière de charge de travail. Par exemple, les applications gourmandes en réseau peuvent nécessiter plus de files d'attente que les applications. CPU-intensive

\* Ces types d’instance comportent plusieurs cartes réseau. Les autres types d’instances sont dotés d’une seule carte réseau. Pour de plus amples informations, veuillez consulter [Cartes réseau](using-eni.md#network-cards). 

## Modification du nombre de files d’attente
<a name="modify"></a>

Vous pouvez modifier le nombre de files d'attente ENA à l'aide du AWS Management Console AWS CLI, ou PowerShell. Dans l’ AWS Management Console, la configuration des files d’attente ENA est disponible sous chaque paramètre d’**interface réseau**.

**Note**  
Votre instance doit être arrêtée avant de modifier le nombre de files ENA.
La valeur des files ENA doit être une puissance de 2, telle que 1, 2, 4, 8, 16, 32, etc.
Le nombre de files d’attente allouées à une seule ENI ne peut pas dépasser le nombre de vCPU disponibles sur votre instance.

Avant de modifier le nombre de files d’attente, utilisez la commande suivante pour vérifier le nombre de files d’attente actuel.

------
#### [ AWS CLI ]

```
aws ec2 describe-instances --instance-id {{i-1234567890abcdef0}}
```

------
#### [ PowerShell ]

```
(Get-EC2Instance -InstanceId i-{{1234567890abcdef0}}).Instances.NetworkInterfaces |
  Select-Object NetworkInterfaceId,
    @{N='DeviceIndex';E={$_.Attachment.DeviceIndex}},
    @{N='AttachmentId';E={$_.Attachment.AttachmentId}},
    @{N='EnaQueueCount';E={$_.Attachment.EnaQueueCount}}
```

### Associer une interface réseau à des files d'attente ENA
<a name="modify-attach"></a>

Dans l'exemple suivant, 16 files d'attente ENA sont configurées sur un ENI.

------
#### [ AWS CLI ]

**Pour associer une interface réseau à des files d'attente ENA**  
Utilisez la commande [attach-network-interface](https://docs.aws.amazon.com/cli/latest/reference/ec2/attach-network-interface.html).

```
aws ec2 attach-network-interface \
  --network-interface-id eni-{{abcdef01234567890}} \
  --instance-id {{i-1234567890abcdef0}} \
  --device-index 1 \
  --ena-queue-count 16
```

------
#### [ PowerShell ]

**Pour associer une interface réseau à des files d'attente ENA**  
Utilisez l’applet de commande [Add-EC2NetworkInterface](https://docs.aws.amazon.com/powershell/latest/reference/items/Add-EC2NetworkInterface.html).

```
Add-EC2NetworkInterface `
  -NetworkInterfaceId eni-{{abcdef01234567890}} `
  -InstanceId {{i-1234567890abcdef0}} `
  -DeviceIndex 1 `
  -EnaQueueCount 16
```

### Lancer une instance avec des files d'attente ENA
<a name="modify-run"></a>

Dans l'exemple suivant, 16 files d'attente ENA sont configurées chacune sur 3 ENI.

------
#### [ AWS CLI ]

**Pour lancer une instance avec des files d'attente ENA**  
Utilisez la commande [run-instances](https://docs.aws.amazon.com/cli/latest/reference/ec2/run-instances.html).

```
aws ec2 run-instances \
  --image-id ami-{{1234567890abcdef0}} \
  --instance-type c8i.4xlarge \
  --network-interfaces \
    "[{\"DeviceIndex\":0,\"SubnetId\":\"subnet-{{abcdef01234567890}}\",\"EnaQueueCount\":16},
      {\"DeviceIndex\":1,\"SubnetId\":\"subnet-{{abcdef01234567890}}\",\"EnaQueueCount\":16},
      {\"DeviceIndex\":2,\"SubnetId\":\"subnet-{{abcdef01234567890}}\",\"EnaQueueCount\":16}]"
```

------
#### [ PowerShell ]

**Pour lancer une instance avec des files d'attente ENA**  
Utilisez l’applet de commande [New-EC2Instance](https://docs.aws.amazon.com/powershell/latest/reference/items/New-EC2Instance.html).

```
New-EC2Instance `
  -ImageId ami-{{1234567890abcdef0}} `
  -InstanceType c8i.4xlarge `
  -NetworkInterface @(
    @{DeviceIndex=0; SubnetId="subnet-{{abcdef01234567890}}"; EnaQueueCount=16},
    @{DeviceIndex=1; SubnetId="subnet-{{abcdef01234567890}}"; EnaQueueCount=16},
    @{DeviceIndex=2; SubnetId="subnet-{{abcdef01234567890}}"; EnaQueueCount=16}
  )
```

### Modifier les files d'attente ENA sur une interface réseau existante
<a name="modify-eni-attribute"></a>

Dans l'exemple suivant, 16 files d'attente ENA sont configurées sur un ENI.

------
#### [ AWS CLI ]

**Pour modifier les files d'attente ENA sur une interface réseau**  
Utilisez la commande [modify-network-interface-attribute](https://docs.aws.amazon.com/cli/latest/reference/ec2/modify-network-interface-attribute.html).

```
aws ec2 modify-network-interface-attribute \
  --network-interface-id eni-{{1234567890abcdef0}} \
  --attachment AttachmentId=eni-attach-{{1234567890abcdef0}},EnaQueueCount=16
```

------
#### [ PowerShell ]

**Pour modifier les files d'attente ENA sur une interface réseau**  
Utilisez l’applet de commande [Edit-EC2NetworkInterfaceAttribute](https://docs.aws.amazon.com/powershell/latest/reference/items/Edit-EC2NetworkInterfaceAttribute.html).

```
Edit-EC2NetworkInterfaceAttribute `
  -NetworkInterfaceId eni-{{1234567890abcdef0}} `
  -Attachment_AttachmentId eni-attach-{{1234567890abcdef0}} `
  -Attachment_EnaQueueCount 16
```

------

Dans l’exemple suivant, le nombre d’ENA est rétabli à la valeur par défaut.

------
#### [ AWS CLI ]

```
aws ec2 modify-network-interface-attribute \
  --network-interface-id eni-{{1234567890abcdef0}} \
  --attachment AttachmentId=eni-attach-{{1234567890abcdef0}},DefaultEnaQueueCount=true
```

------
#### [ PowerShell ]

```
Edit-EC2NetworkInterfaceAttribute `
  -NetworkInterfaceId eni-{{1234567890abcdef0}} `
  -Attachment_AttachmentId eni-attach-{{1234567890abcdef0}} `
  -Attachment_DefaultEnaQueueCount $true
```
