Options¶

--transit-gateway-attachment-id (string)

The ID of the attachment.

--add-subnet-ids (list)

The IDs of one or more subnets to add. You can specify at most one subnet per Availability Zone.

(string)

Syntax:

"string" "string" ...

--remove-subnet-ids (list)

The IDs of one or more subnets to remove.

(string)

Syntax:

"string" "string" ...

--options (structure)

The new VPC attachment options.

DnsSupport -> (string)

Enable or disable DNS support. The default is enable .

SecurityGroupReferencingSupport -> (string)

Enables you to reference a security group across VPCs attached to a transit gateway to simplify security group management.

This option is disabled by default.

For more information about security group referencing, see Security group referencing in the Amazon Web Services Transit Gateways Guide .

Ipv6Support -> (string)

Enable or disable IPv6 support. The default is enable .

ApplianceModeSupport -> (string)

Enable or disable support for appliance mode. If enabled, a traffic flow between a source and destination uses the same Availability Zone for the VPC attachment for the lifetime of that flow. The default is disable .

Shorthand Syntax:

DnsSupport=string,SecurityGroupReferencingSupport=string,Ipv6Support=string,ApplianceModeSupport=string

JSON Syntax:

{
  "DnsSupport": "enable"|"disable",
  "SecurityGroupReferencingSupport": "enable"|"disable",
  "Ipv6Support": "enable"|"disable",
  "ApplianceModeSupport": "enable"|"disable"
}

--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 .

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI 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.

--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. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

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

--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.

Examples¶

Note

To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal's quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .

To modify a transit gateway VPC attachment

The following modify-transit-gateway-vpc-attachment example adds a subnet to the specified transit gateway VPC attachment.

aws ec2 modify-transit-gateway-vpc-attachment \
    --transit-gateway-attachment-id tgw-attach-09fbd47ddfEXAMPLE \
    --add-subnet-ids subnet-0e51f45802EXAMPLE

Output:

{
    "TransitGatewayVpcAttachment": {
        "TransitGatewayAttachmentId": "tgw-attach-09fbd47ddfEXAMPLE",
        "TransitGatewayId": "tgw-0560315ccfEXAMPLE",
        "VpcId": "vpc-5eccc927",
        "VpcOwnerId": "111122223333",
        "State": "modifying",
        "SubnetIds": [
            "subnet-0e51f45802EXAMPLE",
