AWS::EVS::Environment InitialVlans

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.

Syntax

To declare this entity in your AWS CloudFormation template, use the following syntax:

Properties

EdgeVTep

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.

Required: Yes

Type: InitialVlanInfo

Update requires: Updates are not supported.

ExpansionVlan1

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.

Required: Yes

Type: InitialVlanInfo

Update requires: Updates are not supported.

ExpansionVlan2

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.

Required: Yes

Type: InitialVlanInfo

Update requires: Updates are not supported.

Hcx

The HCX VLAN subnet. 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.

Required: Yes

Type: InitialVlanInfo

Update requires: Updates are not supported.

HcxNetworkAclId

A unique ID for a network access control list that the HCX VLAN uses. Required when isHcxPublic is set to true.

Required: No

Type: String

Pattern: ^acl-[a-zA-Z0-9_-]+$

Update requires: No interruption

IsHcxPublic

Determines if the HCX VLAN that Amazon EVS provisions is public or private.

Required: No

Type: Boolean

Update requires: No interruption

The NSX uplink VLAN subnet. This VLAN subnet allows connectivity to the NSX overlay network.

Required: Yes

Type: InitialVlanInfo

Update requires: Updates are not supported.

VmkManagement

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

Required: Yes

Type: InitialVlanInfo

Update requires: Updates are not supported.

VmManagement

The VM management VLAN subnet. This VLAN subnet carries traffic for vSphere virtual machines.

Required: Yes

Type: InitialVlanInfo

Update requires: Updates are not supported.

VMotion

The vMotion VLAN subnet. This VLAN subnet carries traffic for vSphere vMotion.

Required: Yes

Type: InitialVlanInfo

Update requires: Updates are not supported.

VSan

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

Required: Yes

Type: InitialVlanInfo

Update requires: Updates are not supported.

VTep

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

Required: Yes

Type: InitialVlanInfo

Update requires: Updates are not supported.
