Request Parameters Response Elements Errors Examples See Also

CreateNetworkInterface

Creates a network interface in the specified subnet.

For more information about network interfaces, see Elastic Network Interfaces in the Amazon Virtual Private Cloud User Guide.

Request Parameters

The following parameters are for this specific action. For more information about required and optional parameters that are common to all actions, see Common Query Parameters.

Description

A description for the network interface.

Type: String

Required: No

DryRun

Checks whether you have the required permissions for the action, without actually making the request, and provides an error response. If you have the required permissions, the error response is DryRunOperation. Otherwise, it is UnauthorizedOperation.

Type: Boolean

Required: No

InterfaceType

Indicates 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.

Type: String

Valid Values: efa

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. If your subnet has the AssignIpv6AddressOnCreation attribute set to true, you can specify 0 to override this setting.

Type: Integer

Required: No

Ipv6Addresses.N

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 InstanceIpv6Address objects

Required: No

PrivateIpAddress

The primary private IPv4 address of the network interface. If you don't specify an IPv4 address, Amazon EC2 selects one for you from the subnet's IPv4 CIDR range. If you specify an IP address, you cannot indicate any IP addresses specified in privateIpAddresses as primary (only one IP address can be designated as primary).

Type: String

Required: No

PrivateIpAddresses.N

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. When you specify a number of secondary IPv4 addresses, Amazon EC2 selects these IP addresses within the subnet's IPv4 CIDR range. You can't specify this option and specify more than one private IP address using privateIpAddresses.

The number of IP addresses you can assign to a network interface varies by instance type. For more information, see IP Addresses Per ENI Per Instance Type in the Amazon Virtual Private Cloud User Guide.

Type: Integer

Required: No

SecurityGroupId.N

The IDs of one or more security groups.

Type: Array of strings

Required: No

SubnetId

The ID of the subnet to associate with the network interface.

Type: String

Required: Yes

TagSpecification.N

The tags to apply to the new network interface.

Type: Array of TagSpecification objects

Required: No

Response Elements

The following elements are returned by the service.

networkInterface

Information about the network interface.

Type: NetworkInterface object

requestId

The ID of the request.

Type: String

Errors

For information about the errors that are common to all actions, see Common client error codes.
