Request Syntax

response = client.modify_transit_gateway_vpc_attachment(
    TransitGatewayAttachmentId='string',
    AddSubnetIds=[
        'string',
    ],
    RemoveSubnetIds=[
        'string',
    ],
    Options={
        'DnsSupport': 'enable'|'disable',
        'SecurityGroupReferencingSupport': 'enable'|'disable',
        'Ipv6Support': 'enable'|'disable',
        'ApplianceModeSupport': 'enable'|'disable'
    },
    DryRun=True|False
)

Parameters:

• TransitGatewayAttachmentId (string) –

  [REQUIRED]

  The ID of the attachment.

• AddSubnetIds (list) –

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

  • (string) –

• RemoveSubnetIds (list) –

  The IDs of one or more subnets to remove.

  • (string) –

• Options (dict) –

  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 (TGW). Use this option to simplify security group management and control of instance-to-instance traffic across VPCs that are connected by transit gateway. You can also use this option to migrate from VPC peering (which was the only option that supported security group referencing) to transit gateways (which now also support security group referencing). This option is disabled by default and there are no additional costs to use this feature.

    For important information about this feature, see Create a transit gateway attachment to a VPC in the Amazon Web Services Transit Gateway 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.

• DryRun (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.

Return type:

dict
