type Attachment

dict

param Attachment

Information about the interface attachment. If modifying the delete on termination attribute, you must specify the ID of the interface attachment.

  • AttachmentId (string) --

    The ID of the network interface attachment.

  • DeleteOnTermination (boolean) --

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

type Description

dict

param Description

A description for the network interface.

  • Value (string) --

    The attribute value. The value is case-sensitive.

type DryRun

boolean

param 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 Groups

list

param Groups

Changes the security groups for the network interface. The new set of groups you specify replaces the current set. You must specify at least one group, even if it's just the default security group in the VPC. You must specify the ID of the security group, not the name.

  • (string) --

type NetworkInterfaceId

string

param NetworkInterfaceId

[REQUIRED]

The ID of the network interface.

type SourceDestCheck

dict

param SourceDestCheck

Enable or disable source/destination checks, which ensure that the instance is either the source or the destination of any traffic that it receives. If the value is true , source/destination checks are enabled; otherwise, they are disabled. The default value is true . You must disable source/destination checks if the instance runs services such as network address translation, routing, or firewalls.

  • Value (boolean) --

    The attribute value. The valid values are true or false .

type EnaSrdSpecification

dict

param EnaSrdSpecification

Updates the ENA Express configuration for the network interface that’s attached to the instance.

  • EnaSrdEnabled (boolean) --

    Indicates whether ENA Express is enabled for the network interface.

  • EnaSrdUdpSpecification (dict) --

    Configures ENA Express for UDP network traffic.

    • EnaSrdUdpEnabled (boolean) --

      Indicates whether UDP traffic to and from the instance uses ENA Express. To specify this setting, you must first enable ENA Express.

type EnablePrimaryIpv6

boolean

param EnablePrimaryIpv6

If you’re modifying a network interface in a dual-stack or IPv6-only subnet, you have the option to assign a primary IPv6 IP address. A primary IPv6 address is an IPv6 GUA address associated with an ENI that you have enabled to use a primary IPv6 address. Use this option if the instance that this ENI will be attached to relies on its IPv6 address not changing. Amazon Web Services will automatically assign an IPv6 address associated with the ENI attached to your instance to be the primary IPv6 address. Once you enable an IPv6 GUA address to be a primary IPv6, you cannot disable it. 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. If you have multiple IPv6 addresses associated with an ENI attached to your instance and you enable a primary IPv6 address, the first IPv6 GUA address associated with the ENI becomes the primary IPv6 address.

type ConnectionTrackingSpecification

dict

param ConnectionTrackingSpecification

A connection tracking specification.

  • TcpEstablishedTimeout (integer) --

    Timeout (in seconds) for idle TCP connections in an established state. Min: 60 seconds. Max: 432000 seconds (5 days). Default: 432000 seconds. Recommended: Less than 432000 seconds.

  • UdpStreamTimeout (integer) --

    Timeout (in seconds) for idle UDP flows classified as streams which have seen more than one request-response transaction. Min: 60 seconds. Max: 180 seconds (3 minutes). Default: 180 seconds.

  • UdpTimeout (integer) --

    Timeout (in seconds) for idle UDP flows that have seen traffic only in a single direction or a single request-response transaction. Min: 30 seconds. Max: 60 seconds. Default: 30 seconds.

type AssociatePublicIpAddress

boolean

param AssociatePublicIpAddress

Indicates whether to assign a public IPv4 address to a network interface. This option can be enabled for any network interface but will only apply to the primary network interface (eth0).

returns

None
