# Code ENA
<a name="ena-queues"></a>

Le code ENA sono allocate alle interfacce di rete con limiti statici predefiniti in base al tipo e alla dimensione dell’istanza. Sui tipi di istanze supportati, puoi allocare dinamicamente queste code tra interfacce di rete elastiche (ENI). Sebbene il numero totale di code per istanza dipenda dal tipo e dalla dimensione, puoi configurare più ENI con code ENA fino a raggiungere il numero massimo di code per l’ENI e l’istanza.

L’allocazione flessibile delle code ENA ottimizza la distribuzione delle risorse, consentendo il massimo utilizzo della vCPU. I carichi di lavoro ad alte prestazioni di rete richiedono in genere molteplici code ENA. Puoi ottimizzare le prestazioni di rete e i pacchetti al secondo (PPS) regolando il numero di code in base alle esigenze specifiche del carico di lavoro. Ad esempio, le applicazioni che richiedono un uso intensivo della rete potrebbero richiedere più code rispetto alle applicazioni. CPU-intensive

## Modifica il numero di code
<a name="modify"></a>

È possibile modificare il numero di code ENA utilizzando Console di gestione AWS, AWS CLI o. PowerShell Nella Console di gestione AWS, la configurazione delle code ENA è disponibile in ciascuna impostazione dell’**Interfaccia di rete**.

**Nota**  
La tua istanza deve essere arrestata prima di modificare il numero di code ENA.
Il valore per le code ENA deve essere una potenza di 2, ad esempio: 1, 2, 4, 8, 16, 32, ecc.
Il numero di code assegnate a ogni singola ENI non può superare il numero di vCPU disponibili sull’istanza.

Prima di modificare il numero delle code, utilizza il seguente comando per controllare il numero attuale delle code.

------
#### [ 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}}
```

------

### Collega un'interfaccia di rete con le code ENA
<a name="modify-attach"></a>

Nell'esempio seguente, 16 code ENA sono configurate su un ENI.

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

**Per collegare un'interfaccia di rete con code ENA**  
Utilizzate il comando [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 ]

**Per collegare un'interfaccia di rete con code ENA**  
Utilizza il cmdlet [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
```

------

### Avvia un'istanza con code ENA
<a name="modify-run"></a>

Nell'esempio seguente, 16 code ENA sono configurate ciascuna su 3 ENI.

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

**Per avviare un'istanza con code ENA**  
Utilizzare il comando [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 \
