Versions, System Requirements and Installation

Note:

The table below lists recommended versions of VMware software. These recommendations are general and should not replace or override environment-specific recommendations. This information is current as of the publication date of this document.
For the minimum supported version of NSX and other VMware products, see the VMware Product Interoperability Matrix. VMware declares minimum supported versions based on internal testing.

Product or Component	Version
NSX Data Center for vSphere	VMware recommends the latest NSX release for new deployments. When upgrading existing deployments, please review the NSX Data Center for vSphere Release Notes or contact your VMware technical support representative for more information on specific issues before planning an upgrade.
vSphere	For vSphere 6.5: Recommended: 6.5 Update 3 Note: vSphere 6.5 Update 1 resolves the issue of EAM failing with OutOfMemory. See VMware Knowledge Base Article 2135378 for more information. Important: If you are using multicast routing on vSphere 6.5, vSphere 6.5 Update 2 or higher is recommended. If you are using NSX Guest Introspection on vSphere 6.5, vSphere 6.5 P03 or higher is recommended. For vSphere 6.7: Recommended: 6.7 Update 2 Important: If you are using NSX Guest Introspection on vSphere 6.7, please refer to Knowledge Base Article 57248 prior to installing NSX 6.4.6, and consult VMware Customer Support for more information. Note: vSphere 5.5 is not supported with NSX 6.4. Note: vSphere 6.0 has reached End of General Support and is not supported with NSX 6.4.7 onwards.
Guest Introspection for Windows	It is recommended that you upgrade VMware Tools to 10.3.10 before upgrading NSX for vSphere.
Guest Introspection for Linux	Ensure that the guest virtual machine has a supported version of Linux installed. See VMware NSX Administration Guide for latest list of supported Linux versions.

System Requirements and Installation

For the complete list of NSX installation prerequisites, see the System Requirements for NSX section in the NSX Installation Guide.

For installation instructions, see the NSX Installation Guide or the NSX Cross-vCenter Installation Guide.

Deprecated and Discontinued Functionality

End of Life and End of Support Warnings

For information about NSX and other VMware products that must be upgraded soon, please consult the VMware Lifecycle Product Matrix.

NSX for vSphere 6.1.x reached End of Availability (EOA) and End of General Support (EOGS) on January 15, 2017. (See also VMware knowledge base article 2144769.)
vCNS Edges no longer supported. You must upgrade to an NSX Edge first before upgrading to NSX 6.3 or later.
NSX for vSphere 6.2.x has reached End of General Support (EOGS) as of August 20, 2018.
Based on security recommendations, 3DES as an encryption algorithm in NSX Edge IPsec VPN service is no longer supported.
It is recommended that you switch to one of the secure ciphers available in IPsec service. This change regarding encryption algorithm is applicable to IKE SA (phase1) as well as IPsec SA (phase2) negotiation for an IPsec site.

If 3DES encryption algorithm is in use by NSX Edge IPsec service at the time of upgrade to the release in which its support is removed, it will be replaced by another recommended cipher and therefore the IPsec sites that were using 3DES will not come up unless the configuration on the remote peer is modified to match the encryption algorithm used in NSX Edge.

If using 3DES encryption, modify the encryption algorithm in the IPsec site configuration to replace 3DES with one of the supported AES variants (AES / AES256 / AES-GCM). For example, for each IPsec site configuration with the encryption algorithm as 3DES, replace it with AES. Accordingly, update the IPsec configuration at the peer endpoint.

General Behavior Changes

If you have more than one vSphere Distributed Switch, and if VXLAN is configured on one of them, you must connect any Distributed Logical Router interfaces to port groups on that vSphere Distributed Switch. Starting in NSX 6.4.1, this configuration is enforced in the UI and API. In earlier releases, you were not prevented from creating an invalid configuration. If you upgrade to NSX 6.4.1 or later and have incorrectly connected DLR interfaces, you will need to take action to resolve this. See the Upgrade Notes for details.

User Interface Removals and Changes

In NSX 6.4.1, Service Composer Canvas is removed.
In NSX 6.4.7, the following functionality is deprecated in vSphere Client 7.0:
- NSX Edge: SSL VPN-Plus (see KB 79929 for more information)
- Tools: Endpoint Monitoring (all functionality)
- Tools: Flow Monitoring (Flow Monitoring Dashboard, Details by Service, and Configuration)
- System Events: NSX Ticket Logger

Installation Behavior Changes

Starting with version 6.4.2, when you install NSX Data Center for vSphere on hosts that have physical NICs with ixgbe drivers, Receive Side Scaling (RSS) is not enabled on the ixgbe drivers by default. You must enable RSS manually on the hosts before installing NSX Data Center. Make sure that you enable RSS only on the hosts that have NICs with ixgbe drivers. For detailed steps about enabling RSS, see the VMware knowledge base article https://kb.vmware.com/s/article/2034676. This knowledge base article describes recommended RSS settings for improved VXLAN packet throughput.

This new behavior applies only when you are doing a fresh installation of kernel modules (VIB files) on the ESXi hosts. No changes are required when you are upgrading NSX-managed hosts to 6.4.2.

API Removals and Behavior Changes

Deprecations in NSX 6.4.2

The following item is deprecated, and might be removed in a future release:

GET/POST/DELETE /api/2.0/vdn/controller/{controllerId}/syslog. Use GET/PUT /api/2.0/vdn/controller/cluster/syslog instead.

Behavior Changes in NSX 6.4.1

When you create a new IP pool with POST /api/2.0/services/ipam/pools/scope/globalroot-0, or modify an existing IP pool with PUT /api/2.0/services/ipam/pools/, and the pool has multiple IP ranges defined, validation is done to ensure that the ranges do not overlap. This validation was not previously done.

Deprecations in NSX 6.4.0
The following items are deprecated, and might be removed in a future release.

The systemStatus parameter in GET /api/4.0/edges/edgeID/status is deprecated.
GET /api/2.0/services/policy/serviceprovider/firewall/ is deprecated. Use GET /api/2.0/services/policy/serviceprovider/firewall/info instead.
Setting tcpStrict in the global configuration section of Distributed Firewall is deprecated. Starting in NSX 6.4.0, tcpStrict is defined at the section level. Note: If you upgrade to NSX 6.4.0 or later, the global configuration setting for tcpStrict is used to configure tcpStrict in each existing layer 3 section. tcpStrict is set to false in layer 2 sections and layer 3 redirect sections. See "Working with Distributed Firewall Configuration" in the NSX API Guide for more information.

Behavior Changes in NSX 6.4.0
In NSX 6.4.0, the <name> parameter is required when you create a controller with POST /api/2.0/vdn/controller.

NSX 6.4.0 introduces these changes in error handling:

Previously POST /api/2.0/vdn/controller responded with 201 Created to indicate the controller creation job is created. However, the creation of the controller might still fail. Starting in NSX 6.4.0 the response is 202 Accepted.
Previously if you sent an API request which is not allowed in transit or standalone mode, the response status was 400 Bad Request. Starting in 6.4.0 the response status is 403 Forbidden.

CLI Removals and Behavior Changes

Do not use unsupported commands on NSX Controller nodes
There are undocumented commands to configure NTP and DNS on NSX Controller nodes. These commands are not supported, and should not be used on NSX Controller nodes. You should only use commands which are documented in the NSX CLI Guide.

Note: For a list of known issues affecting installation and upgrades, see Installation and Upgrade Known Issues.

General Upgrade Notes

After upgrading vCSA or ESXi to 7.0+, VMs on host experience East/West and North/South connectivity issues. See VMware knowledge base article 85070 for details.
3rd-party integrations that call NSX Controller APIs using weaker ciphers may stop working after upgrade to NSX Data Center for vSphere 6.4.11.
To upgrade NSX, you must perform a full NSX upgrade including host cluster upgrade (which upgrades the host VIBs). For instructions, see the NSX Upgrade Guide including the "Upgrade Host Clusters" section.
Upgrading NSX VIBs on host clusters using VUM is not supported. Use Upgrade Coordinator, Host Preparation, or the associated REST APIs to upgrade NSX VIBs on host clusters.
System Requirements: For information on system requirements while installing and upgrading NSX, see the System Requirements for NSX section in NSX documentation.
Upgrade path for NSX: The VMware Product Interoperability Matrix provides details about the upgrade paths from VMware NSX.
Cross-vCenter NSX upgrade is covered in the NSX Upgrade Guide.
Downgrades are not supported:
- Always capture a backup of NSX Manager before proceeding with an upgrade.
- Once NSX has been upgraded successfully, NSX cannot be downgraded.
To validate that your upgrade to NSX 6.4.x was successful see knowledge base article 2134525.
There is no support for upgrades from vCloud Networking and Security to NSX 6.4.x. You must upgrade to a supported 6.2.x release first.
Interoperability: Check the VMware Product Interoperability Matrix for all relevant VMware products before upgrading.
- Upgrading to NSX Data Center for vSphere 6.4.7: VIO is not compatible with NSX 6.4.7 due to multiple scale issues.
- Upgrading to NSX Data Center for vSphere 6.4: NSX 6.4 is not compatible with vSphere 5.5.
- Upgrading to NSX Data Center for vSphere 6.4.5: If NSX is deployed with VMware Integrated OpenStack (VIO), upgrade VIO to 4.1.2.2 or 5.1.0.1, as 6.4.5 is incompatible with previous releases due to spring package update to version 5.0.
- Upgrading to vSphere 6.5: When upgrading to vSphere 6.5a or later 6.5 versions, you must first upgrade to NSX 6.3.0 or later. NSX 6.2.x is not compatible with vSphere 6.5. See "Upgrading vSphere in an NSX Environment" in the NSX Upgrade Guide.
- Upgrading to vSphere 6.7: When upgrading to vSphere 6.7 you must first upgrade to NSX 6.4.1 or later. Earlier versions of NSX are not compatible with vSphere 6.7. See "Upgrading vSphere in an NSX Environment" in the NSX Upgrade Guide.
Partner services compatibility: If your site uses VMware partner services for Guest Introspection or Network Introspection, you must review the VMware Compatibility Guide before you upgrade, to verify that your vendor's service is compatible with this release of NSX.
Networking and Security plug-in: After upgrading NSX Manager, you must log out and log back in to the vSphere Web Client. If the NSX plug-in does not display correctly, clear your browser cache and history. If the Networking and Security plug-in does not appear in the vSphere Web Client, reset the vSphere Web Client server as explained in the NSX Upgrade Guide.
Stateless environments: In NSX upgrades in a stateless host environment, the new VIBs are pre-added to the Host Image profile during the NSX upgrade process. As a result, NSX on stateless hosts upgrade process follows this sequence:
Prior to NSX 6.2.0, there was a single URL on NSX Manager from which VIBs for a certain version of the ESX Host could be found. (Meaning the administrator only needed to know a single URL, regardless of NSX version.) In NSX 6.2.0 and later, the new NSX VIBs are available at different URLs. To find the correct VIBs, you must perform the following steps:
1. Find the new VIB URL from https://<nsxmanager>/bin/vdn/nwfabric.properties.
2. Fetch VIBs of required ESX host version from corresponding URL.
3. Add them to host image profile.
Service Definitions functionality is not supported in NSX 6.4.7 UI with vSphere Client 7.0:
For example, if you have an old Trend Micro Service Definition registered with vSphere 6.5 or 6.7, follow any one of these two options:
- Option #1: Before upgrading to vSphere 7.0, navigate to the Service Definition tab in the vSphere Web Client, edit the Service Definition to 7.0, and then upgrade to vSphere 7.0.
- Option #2: After upgrading to vSphere 7.0, run the following NSX API to add or edit the Service Definition to 7.0.

POST https://<nsmanager>/api/2.0/si/service/<service-id>/servicedeploymentspec/versioneddeploymentspec

Upgrade Notes for NSX Components

Support for VM Hardware version 11 for NSX components

For new installs of NSX Data Center for vSphere 6.4.2, the NSX components (Manager, Controller, Edge, Guest Introspection) are on VM Hardware version 11.
For upgrades to NSX Data Center for vSphere 6.4.2, the NSX Edge and Guest Introspection components are automatically upgraded to VM Hardware version 11. The NSX Manager and NSX Controller components remain on VM Hardware version 8 following an upgrade. Users have the option to upgrade the VM Hardware to version 11. Consult KB (https://kb.vmware.com/s/article/1010675) for instructions on upgrading VM Hardware versions.
For new installs of NSX 6.3.x, 6.4.0, 6.4.1, the NSX components (Manager, Controller, Edge, Guest Introspection) are on VM Hardware version 8.

NSX Manager Upgrade

Important: If you are upgrading NSX 6.2.0, 6.2.1, or 6.2.2 to NSX 6.3.5 or later, you must complete a workaround before starting the upgrade. See VMware Knowledge Base article 000051624 for details.
If you are upgrading from NSX 6.3.3 to NSX 6.3.4 or later you must first follow the workaround instructions in VMware Knowledge Base article 2151719.
If you use SFTP for NSX backups, change to hmac-sha2-256 after upgrading to 6.3.0 or later because there is no support for hmac-sha1. See VMware Knowledge Base article 2149282 for a list of supported security algorithms.
When you upgrade NSX Manager to NSX 6.4.1, a backup is automatically taken and saved locally as part of the upgrade process. See Upgrade NSX Manager for more information.
When you upgrade to NSX 6.4.0, the TLS settings are preserved. If you have only TLS 1.0 enabled, you will be able to view the NSX plug-in in the vSphere Web Client, but NSX Managers are not visible. There is no impact to datapath, but you cannot change any NSX Manager configuration. Log in to the NSX appliance management web UI at https://nsx-mgr-ip/ and enable TLS 1.1 and TLS 1.2. This reboots the NSX Manager appliance.

Controller Upgrade

The NSX Controller cluster must contain three controller nodes. If it has fewer than three controllers, you must add controllers before starting the upgrade. See Deploy NSX Controller Cluster for instructions.
In NSX 6.3.3, the underlying operating system of the NSX Controller changes. This means that when you upgrade from NSX 6.3.2 or earlier to NSX 6.3.3 or later, instead of an in-place software upgrade, the existing controllers are deleted one at a time, and new Photon OS based controllers are deployed using the same IP addresses.

When the controllers are deleted, this also deletes any associated DRS anti-affinity rules. You must create new anti-affinity rules in vCenter to prevent the new controller VMs from residing on the same host.

See Upgrade the NSX Controller Cluster for more information on controller upgrades.

Host Cluster Upgrade

If you upgrade from NSX 6.3.2 or earlier to NSX 6.3.3 or later, the NSX VIB names change.
The esx-vxlan and esx-vsip VIBs are replaced with esx-nsxv if you have NSX 6.3.3 or later installed on ESXi 6.0 or later.
Rebootless upgrade and uninstall on hosts: On vSphere 6.0 and later, once you have upgraded from NSX 6.2.x to NSX 6.3.x or later, any subsequent NSX VIB changes will not require a reboot. Instead hosts must enter maintenance mode to complete the VIB change. This affects both NSX host cluster upgrade, and ESXi upgrade. See the NSX Upgrade Guide for more information.

NSX Edge Upgrade

Validation added in NSX 6.4.1 to disallow an invalid distributed logical router configurations: In environments where VXLAN is configured and more than one vSphere Distributed Switch is present, distributed logical router interfaces must be connected to the VXLAN-configured vSphere Distributed Switch only. Upgrading a DLR to NSX 6.4.1 or later will fail in those environments if the DLR has interfaces connected to the vSphere Distributed Switch that is not configured for VXLAN. Use the API to connect any incorrectly configured interfaces to port groups on the VXLAN-configured vSphere Distributed Switch. Once the configuration is valid, retry the upgrade. You can change the interface configuration using PUT /api/4.0/edges/{edgeId} or PUT /api/4.0/edges/{edgeId}/interfaces/{index}. See the NSX API Guide for more information.

Delete UDLR Control VM from vCenter Server that is associated with secondary NSX Manager before upgrading UDLR from 6.2.7 to 6.4.5:
In a multi-vCenter environment, when you upgrade NSX UDLRs from 6.2.7 to 6.4.5, the upgrade of the UDLR virtual appliance (UDLR Control VM) fails on the secondary NSX Manager, if HA is enabled on the UDLR Control VM. During the upgrade, the VM with ha index #0 in the HA pair is removed from the NSX database; but, this VM continues to exist on the vCenter Server. Therefore, when the UDLR Control VM is upgraded on the secondary NSX Manager, the upgrade fails because the name of the VM clashes with an existing VM on the vCenter Server. To resolve this issue, delete the Control VM from the vCenter Server that is associated with the UDLR on the secondary NSX Manager, and then upgrade the UDLR from 6.2.7 to 6.4.5.
Host clusters must be prepared for NSX before upgrading NSX Edge appliances: Management-plane communication between NSX Manager and Edge via the VIX channel is no longer supported starting in 6.3.0. Only the message bus channel is supported. When you upgrade from NSX 6.2.x or earlier to NSX 6.3.0 or later, you must verify that host clusters where NSX Edge appliances are deployed are prepared for NSX, and that the messaging infrastructure status is GREEN. If host clusters are not prepared for NSX, upgrade of the NSX Edge appliance will fail. See "Upgrade NSX Edge" in the NSX Upgrade Guide for details.

Upgrading Edge Services Gateway (ESG):
Starting in NSX 6.2.5, resource reservation is carried out at the time of NSX Edge upgrade. When vSphere HA is enabled on a cluster having insufficient resources, the upgrade operation may fail due to vSphere HA constraints being violated.

To avoid such upgrade failures, perform the following steps before you upgrade an ESG:

The following resource reservations are used by the NSX Manager if you have not explicitly set values at the time of install or upgrade.

NSX Edge Form Factor	CPU Reservation	Memory Reservation
COMPACT	1000MHz	512 MB
LARGE	2000MHz	1024 MB
QUADLARGE	4000MHz	2048 MB
X-LARGE	6000MHz	8192 MB

Always ensure that your installation follows the best practices laid out for vSphere HA. Refer to document Knowledge Base article 1002080 .
Use the NSX tuning configuration API:
PUT https://<nsxmanager>/api/4.0/edgePublish/tuningConfiguration
ensuring that values for edgeVCpuReservationPercentage and edgeMemoryReservationPercentage fit within available resources for the form factor (see table above for defaults).

Disable vSphere's Virtual Machine Startup option where vSphere HA is enabled and Edges are deployed. After you upgrade your 6.2.4 or earlier NSX Edges to 6.2.5 or later, you must turn off the vSphere Virtual Machine Startup option for each NSX Edge in a cluster where vSphere HA is enabled and Edges are deployed. To do this, open the vSphere Web Client, find the ESXi host where NSX Edge virtual machine resides, click Manage > Settings, and, under Virtual Machines, select VM Startup/Shutdown, click Edit, and make sure that the virtual machine is in Manual mode (that is, make sure it is not added to the Automatic Startup/Shutdown list).

Before upgrading to NSX 6.2.5 or later, make sure all load balancer cipher lists are colon separated. If your cipher list uses another separator such as a comma, make a PUT call to https://nsxmgr_ip/api/4.0/edges/EdgeID/loadbalancer/config/applicationprofiles and replace each <ciphers> </ciphers> list in <clientssl> </clientssl> and <serverssl> </serverssl> with a colon-separated list. For example, the relevant segment of the request body might look like the following. Repeat this procedure for all application profiles:

<applicationProfile>
  <name>https-profile</name>
  <insertXForwardedFor>false</insertXForwardedFor>
  <sslPassthrough>false</sslPassthrough>
  <template>HTTPS</template>
  <serverSslEnabled>true</serverSslEnabled>
  <clientSsl>
    <ciphers>AES128-SHA:AES256-SHA:ECDHE-ECDSA-AES256-SHA</ciphers>
    <clientAuth>ignore</clientAuth>
    <serviceCertificate>certificate-4</serviceCertificate>
  </clientSsl>
  <serverSsl>
    <ciphers>AES128-SHA:AES256-SHA:ECDHE-ECDSA-AES256-SHA</ciphers>
    <serviceCertificate>certificate-4</serviceCertificate>
  </serverSsl>
  ...
</applicationProfile>

Set Correct Cipher version for Load Balanced Clients on vROPs versions older than 6.2.0: vROPs pool members on vROPs versions older than 6.2.0 use TLS version 1.0 and therefore you must set a monitor extension value explicitly by setting "ssl-version=10" in the NSX Load Balancer configuration. See "Create a Service Monitor" in the NSX Administration Guide for instructions.
```
{
    "expected" : null,
    "extension" : "ssl-version=10",
    "send" : null,
    "maxRetries" : 2,
    "name" : "sm_vrops",
    "url" : "/suite-api/api/deployment/node/status",
    "timeout" : 5,
    "type" : "https",
    "receive" : null,
    "interval" : 60,
    "method" : "GET"
}
```
After upgrading to NSX 6.4.6, L2 bridges and interfaces on a DLR cannot connect to logical switches belonging to different transport zones: In NSX 6.4.5 or earlier, L2 bridge instances and interfaces on a Distributed Logical Router (DLR) supported use of logical switches that belonged to different transport zones. Starting in NSX 6.4.6, this configuration is not supported. The L2 bridge instances and interfaces on a DLR must connect to logical switches that are in a single transport zone. If logical switches from multiple transport zones are used, edge upgrade is blocked during pre-upgrade validation checks when you upgrade NSX to 6.4.6. To resolve this edge upgrade issue, ensure that the bridge instances and interfaces on a DLR are connected to logical switches in a single transport zone.
After upgrading to NSX 6.4.7, bridges and interfaces on a DLR cannot connect to dvPortGroups belonging to different VDS: If such a configuration is present, NSX Manager upgrade to 6.4.7 is blocked in pre-upgrade validation checks. To resolve this, ensure that interfaces and L2 bridges of a DLR are connected to a single VDS.
After upgrading to NSX 6.4.7, DLR cannot be connected to VLAN-backed port groups if the transport zone of logical switch it is connected to spans more than one VDS: This is to ensure correct alignment of DLR instances with logical switch dvPortGroups across hosts. If such configuration is present, NSX Manager upgrade to 6.4.7 is blocked in pre-upgrade validation checks. To resolve this issue, ensure that there are no logical interfaces connected to VLAN-backed port groups, if a logical interface exists with a logical switch belonging to a transport zone spanning multiple VDS.
After upgrading to NSX 6.4.7, different DLRs cannot have their interfaces and L2 bridges on a same network: If such a configuration is present, NSX Manager upgrade to 6.4.7 is blocked in pre-upgrade validation checks. To resolve this issue, ensure that a network is used in only a single DLR.

Upgrade Notes for FIPS

When you upgrade from a version of NSX earlier than NSX 6.3.0 to NSX 6.3.0 or later, you must not enable FIPS mode before the upgrade is completed. Enabling FIPS mode before the upgrade is complete will interrupt communication between upgraded and not-upgraded components. See "Understanding FIPS Mode and NSX Upgrade" in the NSX Upgrade Guide for more information.

Ciphers supported on OS X Yosemite and OS X El Capitan: If you are using SSL VPN client on OS X 10.11 (EL Capitan), you will be able to connect using AES128-GCM-SHA256, ECDHE-RSA-AES128-GCM-SHA256, ECDHE-RSA-AES256-GCM-SHA38, AES256-SHA and AES128-SHA ciphers and those using OS X 10.10 (Yosemite) will be able to connect using AES256-SHA and AES128-SHA ciphers only.
Do not enable FIPS before the upgrade to NSX 6.3.x is complete. See "Understanding FIPS Mode and NSX Upgrade" in the NSX Upgrade Guide for more information.
Before you enable FIPS, verify any partner solutions are FIPS mode certified. See the VMware Compatibility Guide and the relevant partner documentation.

FIPS Compliance

NSX 6.4 uses FIPS 140-2 validated cryptographic modules for all security-related cryptography when correctly configured.

Note:

Controller and Clustering VPN: The NSX Controller uses IPsec VPN to connect Controller clusters. The IPsec VPN uses the VMware Linux Kernel Cryptographic Module (VMware Photon OS 1.0 environment), which is in the process of being CMVP validated.
Edge IPsec VPN: The NSX Edge IPsec VPN uses the VMware Linux Kernel Cryptographic Module (VMware NSX OS 4.4 environment), which is in the process of being CMVP validated.
