# ENA queues ENA queues are allocated to network interfaces with default static limits based on the instance type and size. On supported instance types, you can dynamically allocate these queues across Elastic Network Interfaces (ENIs). While the total queue count per instance depends on its type and size, you can configure multiple ENIs with ENA queues until you meet the maximum queue count for the ENI and the instance. Flexible ENA queue allocation optimizes resource distribution, enabling maximum vCPU utilization. High network performance workloads typically require multiple ENA queues. You can fine-tune network performance and packets per second (PPS) by adjusting queue counts according to your specific workload needs. For example, network-intensive applications may require more queues compared to CPU-intensive applications. **Topics** + [Supported instances](#supported-instances) + [Modify the number of queues](#modify) ## Supported instances The following instances support dynamic allocation of multiple ENA queues. ### General purpose

**Note** \* These instance types feature multiple network cards. Other instance types feature a single network card. For more information, see [Network cards](using-eni.md#network-cards). ## Modify the number of queues You can modify the number of ENA queues using the AWS Management Console, AWS CLI, or PowerShell. In the AWS Management Console, the ENA queues configuration is available under each **Network interface** setting. **Note** Your instance must be stopped before modifying the number of ENA queues. The value for ENA queues must be a power of 2, such as, 1, 2, 4, 8, 16, 32, etc. The number of queues allocated to any single ENI cannot exceed the number of vCPUs available on your instance. Before modifying the queue count, use the following command to check your current queue count. ------ #### [ 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}} ``` ------ ### Attach a network interface with ENA queues In the following example, 16 ENA queues are configured on an ENI. ------ #### [ AWS CLI ] **To attach a network interface with ENA queues** Use the [attach-network-interface](https://docs.aws.amazon.com/cli/latest/reference/ec2/attach-network-interface.html) command. ``` aws ec2 attach-network-interface \ --network-interface-id eni-{{abcdef01234567890}} \ --instance-id {{i-1234567890abcdef0}} \ --device-index 1 \ --ena-queue-count 16 ``` ------ #### [ PowerShell ] **To attach a network interface with ENA queues** Use the [Add-EC2NetworkInterface](https://docs.aws.amazon.com/powershell/latest/reference/items/Add-EC2NetworkInterface.html) cmdlet. ``` Add-EC2NetworkInterface ` -NetworkInterfaceId eni-{{abcdef01234567890}} ` -InstanceId {{i-1234567890abcdef0}} ` -DeviceIndex 1 ` -EnaQueueCount 16 ``` ------ ### Launch an instance with ENA queues In the following example, 16 ENA queues each are configured on 3 ENIs. ------ #### [ AWS CLI ] **To launch an instance with ENA queues** Use the [run-instances](https://docs.aws.amazon.com/cli/latest/reference/ec2/run-instances.html) command. ``` 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 ] **To launch an instance with ENA queues** Use the [New-EC2Instance](https://docs.aws.amazon.com/powershell/latest/reference/items/New-EC2Instance.html) cmdlet. ``` 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} ) ``` ------ ### Modify ENA queues on an existing network interface In the following example, 16 ENA queues are configured on an ENI. ------ #### [ AWS CLI ] **To modify ENA queues on a network interface** Use the [modify-network-interface-attribute](https://docs.aws.amazon.com/cli/latest/reference/ec2/modify-network-interface-attribute.html) command. ``` aws ec2 modify-network-interface-attribute \ --network-interface-id eni-{{1234567890abcdef0}} \ --attachment AttachmentId=eni-attach-{{1234567890abcdef0}},EnaQueueCount=16 ``` ------ #### [ PowerShell ] **To modify ENA queues on a network interface** Use the [Edit-EC2NetworkInterfaceAttribute](https://docs.aws.amazon.com/powershell/latest/reference/items/Edit-EC2NetworkInterfaceAttribute.html) cmdlet. ``` Edit-EC2NetworkInterfaceAttribute ` -NetworkInterfaceId eni-{{1234567890abcdef0}} ` -Attachment_AttachmentId eni-attach-{{1234567890abcdef0}} ` -Attachment_EnaQueueCount 16 ``` ------ In the following example, the ENA count is reset to the default value. ------ #### [ 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 ``` ------
