public class ModifyTransitGatewayVpcAttachmentRequestOptions

The ModifyTransitGatewayVpcAttachmentRequestOptions type exposes the following members



Public Property ApplianceModeSupport Amazon.EC2.ApplianceModeSupportValue

Gets and sets the property ApplianceModeSupport.

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.

Public Property DnsSupport Amazon.EC2.DnsSupportValue

Gets and sets the property DnsSupport.

Enable or disable DNS support. The default is enable.

Public Property Ipv6Support Amazon.EC2.Ipv6SupportValue

Gets and sets the property Ipv6Support.

Enable or disable IPv6 support. The default is enable.

Public Property SecurityGroupReferencingSupport Amazon.EC2.SecurityGroupReferencingSupportValue

Gets and sets the property SecurityGroupReferencingSupport.

This parameter is in preview and may not be available for your account.

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