InitialVlansProperty Struct ​

The initial VLAN subnets for the environment.

Amazon EVS VLAN subnets have a minimum CIDR block size of /28 and a maximum size of /24. Amazon EVS VLAN subnet CIDR blocks must not overlap with other subnets in the VPC.

Properties ​

edgeVTepIResolvable | CfnEnvironment.InitialVlanInfoPropertyedge_v_teptyping.Union[IResolvable, InitialVlanInfoProperty]edgeVTepIResolvableEdgeVTepIResolvableEdgeVTepinterface{}required#
The edge VTEP VLAN subnet.

This VLAN subnet manages traffic flowing between the internal network and external networks, including internet access and other site connections.

expansionVlan1IResolvable | CfnEnvironment.InitialVlanInfoPropertyexpansion_vlan1typing.Union[IResolvable, InitialVlanInfoProperty]expansionVlan1IResolvableExpansionVlan1IResolvableExpansionVlan1interface{}required#
An additional VLAN subnet that can be used to extend VCF capabilities once configured.

For example, you can configure an expansion VLAN subnet to use NSX Federation for centralized management and synchronization of multiple NSX deployments across different locations.

expansionVlan2IResolvable | CfnEnvironment.InitialVlanInfoPropertyexpansion_vlan2typing.Union[IResolvable, InitialVlanInfoProperty]expansionVlan2IResolvableExpansionVlan2IResolvableExpansionVlan2interface{}required#
An additional VLAN subnet that can be used to extend VCF capabilities once configured.

For example, you can configure an expansion VLAN subnet to use NSX Federation for centralized management and synchronization of multiple NSX deployments across different locations.

hcxIResolvable | CfnEnvironment.InitialVlanInfoPropertyhcxtyping.Union[IResolvable, InitialVlanInfoProperty]hcxIResolvableHcxIResolvableHcxinterface{}required#
The HCX VLAN subnet.
notes

This VLAN subnet allows the HCX Interconnnect (IX) and HCX Network Extension (NE) to reach their peers and enable HCX Service Mesh creation.

If you plan to use a public HCX VLAN subnet, the following requirements must be met:

  • Must have a /28 netmask and be allocated from the IPAM public pool. Required for HCX internet access configuration.
  • The HCX public VLAN CIDR block must be added to the VPC as a secondary CIDR block.
  • Must have at least two Elastic IP addresses to be allocated from the public IPAM pool for HCX components.
hcxNetworkAclIdoptionalstringhcx_network_acl_idoptionalstrhcxNetworkAclIdoptionalStringHcxNetworkAclIdoptionalstringHcxNetworkAclIdoptional*string#
A unique ID for a network access control list that the HCX VLAN uses.

Required when isHcxPublic is set to true .

isHcxPublicoptionalboolean | IResolvableis_hcx_publicoptionaltyping.Union[bool, IResolvable]isHcxPublicoptionalBooleanIsHcxPublicoptionalboolIsHcxPublicoptionalinterface{}#
Determines if the HCX VLAN that Amazon EVS provisions is public or private.
vmkManagementIResolvable | CfnEnvironment.InitialVlanInfoPropertyvmk_managementtyping.Union[IResolvable, InitialVlanInfoProperty]vmkManagementIResolvableVmkManagementIResolvableVmkManagementinterface{}required#
The host VMkernel management VLAN subnet.

This VLAN subnet carries traffic for managing ESXi hosts and communicating with VMware vCenter Server.

vmManagementIResolvable | CfnEnvironment.InitialVlanInfoPropertyvm_managementtyping.Union[IResolvable, InitialVlanInfoProperty]vmManagementIResolvableVmManagementIResolvableVmManagementinterface{}required#
The VM management VLAN subnet.

This VLAN subnet carries traffic for vSphere virtual machines.

vMotionIResolvable | CfnEnvironment.InitialVlanInfoPropertyv_motiontyping.Union[IResolvable, InitialVlanInfoProperty]vMotionIResolvableVMotionIResolvableVMotioninterface{}required#
The vMotion VLAN subnet.

This VLAN subnet carries traffic for vSphere vMotion.

vSanIResolvable | CfnEnvironment.InitialVlanInfoPropertyv_santyping.Union[IResolvable, InitialVlanInfoProperty]vSanIResolvableVSanIResolvableVSaninterface{}required#
The vSAN VLAN subnet.

This VLAN subnet carries the communication between ESXi hosts to implement a vSAN shared storage pool.

vTepIResolvable | CfnEnvironment.InitialVlanInfoPropertyv_teptyping.Union[IResolvable, InitialVlanInfoProperty]vTepIResolvableVTepIResolvableVTepinterface{}required#
The VTEP VLAN subnet.

This VLAN subnet handles internal network traffic between virtual machines within a VCF instance.
