Options¶

--ena-srd-specification (structure)

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 -> (structure)

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.

Shorthand Syntax:

EnaSrdEnabled=boolean,EnaSrdUdpSpecification={EnaSrdUdpEnabled=boolean}

JSON Syntax:

{
  "EnaSrdEnabled": true|false,
  "EnaSrdUdpSpecification": {
    "EnaSrdUdpEnabled": true|false
  }
}

--enable-primary-ipv6 | --no-enable-primary-ipv6 (boolean)

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.

--connection-tracking-specification (structure)

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.

Shorthand Syntax:

TcpEstablishedTimeout=integer,UdpStreamTimeout=integer,UdpTimeout=integer

JSON Syntax:

{
  "TcpEstablishedTimeout": integer,
  "UdpStreamTimeout": integer,
  "UdpTimeout": integer
}

--associate-public-ip-address | --no-associate-public-ip-address (boolean)

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).

--dry-run | --no-dry-run (boolean)

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 .

--network-interface-id (string)

The ID of the network interface.

--description (structure)

A description for the network interface.

Value -> (string)

The attribute value. The value is case-sensitive.

--source-dest-check | --no-source-dest-check (structure)

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 .

--groups (list)

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)

Syntax:

"string" "string" ...

--attachment (structure)

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.

Shorthand Syntax:

AttachmentId=string,DeleteOnTermination=boolean

JSON Syntax:

{
  "AttachmentId": "string",
  "DeleteOnTermination": true|false
}

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.

Global Options¶

--debug (boolean)

Turn on debug logging.

--endpoint-url (string)

Override command’s default URL with the given URL.

--no-verify-ssl (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

--no-paginate (boolean)

Disable automatic pagination. If automatic pagination is disabled, the AWS CLI will only make one call, for the first page of results.

--output (string)

The formatting style for command output.

json
text
table
yaml
yaml-stream

--query (string)

A JMESPath query to use in filtering the response data.

--profile (string)

Use a specific profile from your credential file.

--region (string)

The region to use. Overrides config/env settings.

--version (string)

Display the version of this tool.

--color (string)

Turn on/off color output.

on
off
auto

--no-sign-request (boolean)

Do not sign requests. Credentials will not be loaded if this argument is provided.

--ca-bundle (string)

The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.

--cli-read-timeout (int)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.

--cli-binary-format (string)

The formatting style to be used for binary blobs. The default format is base64. The base64 format expects binary blobs to be provided as a base64 encoded string. The raw-in-base64-out format preserves compatibility with AWS CLI V1 behavior and binary values must be passed literally. When providing contents from a file that map to a binary blob fileb:// will always be treated as binary and use the file contents directly regardless of the cli-binary-format setting. When using file:// the file contents will need to properly formatted for the configured cli-binary-format.

base64
raw-in-base64-out

--no-cli-pager (boolean)

Disable cli pager for output.

--cli-auto-prompt (boolean)

Automatically prompt for CLI input parameters.

--no-cli-auto-prompt (boolean)

Disable automatically prompt for CLI input parameters.
