About ModifyNetworkInterfaceAttribute

Modifies the specified network interface attribute. You can specify only one attribute at a time. You can use this action to attach and detach security groups from an existing EC2 instance.

Method Signature

IMPORTING

Required arguments:

IV_NETWORKINTERFACEID TYPE /AWS1/EC2NETWORKINTERFACEID /AWS1/EC2NETWORKINTERFACEID

The ID of the network interface.

Optional arguments:

IO_ENASRDSPECIFICATION TYPE REF TO /AWS1/CL_EC2ENASRDSPEC /AWS1/CL_EC2ENASRDSPEC

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

IV_ENABLEPRIMARYIPV6 TYPE /AWS1/EC2BOOLEAN /AWS1/EC2BOOLEAN

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.

IO_CONNECTIONTRACKINGSPEC TYPE REF TO /AWS1/CL_EC2CONNTRKSPECREQUEST /AWS1/CL_EC2CONNTRKSPECREQUEST

A connection tracking specification.

IV_ASSOCIATEPUBLICIPADDRESS TYPE /AWS1/EC2BOOLEAN /AWS1/EC2BOOLEAN

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).

IV_DRYRUN TYPE /AWS1/EC2BOOLEAN /AWS1/EC2BOOLEAN

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.

IO_DESCRIPTION TYPE REF TO /AWS1/CL_EC2ATTRIBUTEVALUE /AWS1/CL_EC2ATTRIBUTEVALUE

A description for the network interface.

IO_SOURCEDESTCHECK TYPE REF TO /AWS1/CL_EC2ATTRBOOLEANVALUE /AWS1/CL_EC2ATTRBOOLEANVALUE

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.

IT_GROUPS TYPE /AWS1/CL_EC2SECGRPIDSTRLIST_W=>TT_SECURITYGROUPIDSTRINGLIST TT_SECURITYGROUPIDSTRINGLIST

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.

IO_ATTACHMENT TYPE REF TO /AWS1/CL_EC2NETWORKINTERFACE09 /AWS1/CL_EC2NETWORKINTERFACE09

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