LaunchTemplateInstanceNetworkInterfaceSpecificationRequest

The parameters for a network interface.

AssociateCarrierIpAddress

Associates a Carrier IP address with eth0 for a new network interface.

Use this option when you launch an instance in a Wavelength Zone and want to associate a Carrier IP address with the network interface. For more information about Carrier IP addresses, see Carrier IP addresses in the AWS Wavelength Developer Guide.

Type: Boolean

Required: No

AssociatePublicIpAddress

Associates a public IPv4 address with eth0 for a new network interface.

AWS charges for all public IPv4 addresses, including public IPv4 addresses associated with running instances and Elastic IP addresses. For more information, see the Public IPv4 Address tab on the Amazon VPC pricing page.

Type: Boolean

Required: No

ConnectionTrackingSpecification

A security group connection tracking specification that enables you to set the timeout for connection tracking on an Elastic network interface. For more information, see Idle connection tracking timeout in the Amazon EC2 User Guide.

Type: ConnectionTrackingSpecificationRequest object

Required: No

DeleteOnTermination

Indicates whether the network interface is deleted when the instance is terminated.

Type: Boolean

Required: No

Description

A description for the network interface.

Type: String

Required: No

DeviceIndex

The device index for the network interface attachment. Each network interface requires a device index. If you create a launch template that includes secondary network interfaces but not a primary network interface, then you must add a primary network interface as a launch parameter when you launch an instance from the template.

Type: Integer

Required: No

EnaSrdSpecification

Configure ENA Express settings for your launch template.

Type: EnaSrdSpecificationRequest object

Required: No

InterfaceType

The type of network interface. To create an Elastic Fabric Adapter (EFA), specify efa or efa. For more information, see Elastic Fabric Adapter in the Amazon EC2 User Guide.

If you are not creating an EFA, specify interface or omit this parameter.

If you specify efa-only, do not assign any IP addresses to the network interface. EFA-only network interfaces do not support IP addresses.

Valid values: interface | efa | efa-only

Type: String

Required: No

Ipv4Prefixes

One or more IPv4 prefixes to be assigned to the network interface. You cannot use this option if you use the Ipv4PrefixCount option.

Type: Array of Ipv4PrefixSpecificationRequest objects

Required: No

Ipv4PrefixCount

The number of IPv4 prefixes to be automatically assigned to the network interface. You cannot use this option if you use the Ipv4Prefix option.

Type: Integer

Required: No

Ipv6AddressCount

The number of IPv6 addresses to assign to a network interface. Amazon EC2 automatically selects the IPv6 addresses from the subnet range. You can't use this option if specifying specific IPv6 addresses.

Type: Integer

Required: No

Ipv6Addresses

One or more specific IPv6 addresses from the IPv6 CIDR block range of your subnet. You can't use this option if you're specifying a number of IPv6 addresses.

Type: Array of InstanceIpv6AddressRequest objects

Required: No

Ipv6Prefixes

One or more IPv6 prefixes to be assigned to the network interface. You cannot use this option if you use the Ipv6PrefixCount option.

Type: Array of Ipv6PrefixSpecificationRequest objects

Required: No

Ipv6PrefixCount

The number of IPv6 prefixes to be automatically assigned to the network interface. You cannot use this option if you use the Ipv6Prefix option.

Type: Integer

Required: No

NetworkCardIndex

The index of the network card. Some instance types support multiple network cards. The primary network interface must be assigned to network card index 0. The default is network card index 0.

Type: Integer

Required: No

NetworkInterfaceId

The ID of the network interface.

Type: String

Required: No

PrimaryIpv6

The primary IPv6 address of the network interface. When you enable an IPv6 GUA address to be a primary IPv6, the first IPv6 GUA will be made the primary IPv6 address until the instance is terminated or the network interface is detached. For more information about primary IPv6 addresses, see RunInstances.

Type: Boolean

Required: No

PrivateIpAddress

The primary private IPv4 address of the network interface.

Type: String

Required: No

PrivateIpAddresses

One or more private IPv4 addresses.

Type: Array of PrivateIpAddressSpecification objects

Required: No

SecondaryPrivateIpAddressCount

The number of secondary private IPv4 addresses to assign to a network interface.

Type: Integer

Required: No

Groups

The IDs of one or more security groups.

Type: Array of strings

Required: No

SubnetId

The ID of the subnet for the network interface.

Type: String

Required: No
