ENA queues
Elastic Network Adapter (ENA) queues handle packet processing for your Amazon EC2 network interfaces. Each instance type has a set number of ENA queues shared across its Elastic Network Interfaces (ENIs). By default, each ENI gets a fixed queue count based on the instance type and size.
With configurable ENA queue allocation, you can choose how many queues each ENI gets. The total per ENI and per instance is still capped. This helps you match packet processing to your workload. For example, you can give more queues to an ENI with heavy traffic and fewer to one with light traffic.
ENA queue specifications for EC2 instance types
The following tables list instance types that support configurable ENA queue allocation, along with their default and maximum queue values.
Note
For ENA queue values for all instance types, including types that do not support configurable ENA queue allocation, see the Network specifications tables in the Amazon EC2 Instance Types guide.

* These instance types feature multiple network cards. Other instance types feature a single network card. For more information, see Network cards.
Configure ENA queue allocation
On supported instance types, you can configure the ENA queue count for each ENI. Use the Amazon Web Services Management Console, Amazon CLI, or PowerShell. In the Amazon Web Services Management Console, this setting appears under each Network interface.
Note
Before you configure ENA queues, note the following requirements:
-
Your instance must be stopped before you configure the number of ENA queues.
-
The value for ENA queues must be a power of 2, such as 1, 2, 4, 8, 16, or 32.
-
The number of queues on any single ENI cannot exceed the number of vCPUs on your instance.
Before you change the queue count, check your current count with the following command.
- Amazon CLI
-
aws ec2 describe-instances --instance-idi-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.
- Amazon CLI
-
To attach a network interface with ENA queues
Use the attach-network-interface command.
aws ec2 attach-network-interface \ --network-interface-id eni-abcdef01234567890\ --instance-idi-1234567890abcdef0\ --device-index 1 \ --ena-queue-count 16 - PowerShell
-
To attach a network interface with ENA queues
Use the Add-EC2NetworkInterface cmdlet.
Add-EC2NetworkInterface ` -NetworkInterfaceId eni-abcdef01234567890` -InstanceIdi-1234567890abcdef0` -DeviceIndex 1 ` -EnaQueueCount 16
Launch an instance with ENA queues
In the following example, 16 ENA queues each are configured on 3 ENIs.
- Amazon CLI
-
To launch an instance with ENA queues
Use the run-instances 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 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.
- Amazon CLI
-
To modify ENA queues on a network interface
Use the modify-network-interface-attribute 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 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.
- Amazon 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
