Properties

AssociateCarrierIpAddress

Indicates whether to associate 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 Amazon Wavelength Developer Guide.

Required: No

Type: Boolean

Update requires: No interruption

AssociatePublicIpAddress

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

Required: No

Type: Boolean

Update requires: No interruption

DeleteOnTermination

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

Required: No

Type: Boolean

Update requires: No interruption

Description

A description for the network interface.

Required: No

Type: String

Update requires: No interruption

DeviceIndex

The device index for the network interface attachment.

Required: No

Type: Integer

Update requires: No interruption

Groups

The IDs of one or more security groups.

Required: No

Type: List of String

Update requires: No interruption

InterfaceType

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

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

Valid values: interface | efa

Required: No

Type: String

Update requires: No interruption

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.

Required: No

Type: Integer

Update requires: No interruption

Ipv4Prefixes

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

Required: No

Type: List of Ipv4PrefixSpecification

Update requires: No interruption

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.

Required: No

Type: Integer

Update requires: No interruption

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.

Required: No

Type: List of Ipv6Add

Update requires: No interruption

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.

Required: No

Type: Integer

Update requires: No interruption

Ipv6Prefixes

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

Required: No

Type: List of Ipv6PrefixSpecification

Update requires: No interruption

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.

Required: No

Type: Integer

Update requires: No interruption

NetworkInterfaceId

The ID of the network interface.

Required: No

Type: String

Update requires: No interruption

PrivateIpAddress

The primary private IPv4 address of the network interface.

Required: No

Type: String

Update requires: No interruption

PrivateIpAddresses

One or more private IPv4 addresses.

Required: No

Type: List of PrivateIpAdd

Update requires: No interruption

SecondaryPrivateIpAddressCount

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

Required: No

Type: Integer

Update requires: No interruption

SubnetId

The ID of the subnet for the network interface.

Required: No

Type: String

Update requires: No interruption
