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.

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.

Upgrade Notes

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

General Upgrade Notes

  • 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: 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.

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

    1. Always ensure that your installation follows the best practices laid out for vSphere HA. Refer to document Knowledge Base article 1002080 .

    2. 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"
}

 

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 Understand 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.

Document Revision History

29th April 2019: Second edition. Updated issue 2312793.

Resolved Issues

  • Fixed Issue 1747978: OSPF adjacencies are deleted with MD5 authentication after NSX Edge HA failover
    In an NSX for vSphere 6.2.4 environment where the NSX Edge is configured for HA with OSPF graceful restart configured and MD5 is used for authentication, OSPF fails to start gracefully. Adjacencies forms only after the dead timer expires on the OSPF neighbor nodes.
  • Fixed Issue 2106417: GI SVM goes into Failed state after NSX Manager is upgraded from 6.3.0 to 6.4.1

    If you are using vCenter Server 6.5 u1, and upgrade NSX Manager from 6.3.0 to 6.4.1, GI SVM upgrade might be Failed.

  • Fixed Issue 2171182: Unable to create or manage multiple replication clusters from the Hardware Devices tab in the NSX user interface

    Through the NSX user interface, you are able to view and manage a single default replication cluster, but not multiple replication clusters.

  • Fixed Issue 2145540: For ESX version 6.7, total number of underlay multicast groups joined by a host cannot exceed 128

    It is recommended that you use replication multicast range of 64 or less (CIDR /26 or higher) while configuring multicast routing under a DLR.

  • Fixed Issue 2197754: Hosts show purple diagnostic screen when vSphere Distributed Switch is upgraded to 6.6

    If you have NSX 6.4 installed, and you upgrade vSphere Distributed Switches to version 6.6, ESXi displays a purple diagnostic screen. New installs of vSphere 6.7 with vSphere Distributed Switch 6.6 are not affected. Fixed in vSphere 6.7 U1.

  • Fixed Issue 2236618: Vnic/Appliance configuration operation on ESG with 10K static routes show around 2 minutes in response time

    With increasing numbers of static routes, vnic/appliance configuration operation takes more time to complete. User interface operations for configuring vnics/sub interfaces/appliances may time out when crossing 2 minute limit, however the configuration succeeds.

  • Fixed Issue 2239686: Configuring multicast on ESG (XLARGE or QUADLARGE) with 10K static routes takes around 2 minutes

    With increasing number of static routes configured, BGP/OSPF/Global configuration in Routing Configuration operation will start taking more time to complete. Once multicast has been configured, subsequent BGP/OSPF/Global configuration in Routing Configuration succeeds but takes more time. User interface operations for configuring BGP/OSPF/Global in Routing Configuration may time out on crossing 2 minute limit, however the configuration will succeed. In such cases, UI should be refreshed to reflect the status of the configuration change.

  • Fixed Issue 2310005: The taskframework task data generated as part of high CPU usage monitoring tool is populated in the vsm.log file and not in the taskdata.csv file

    The taskframework task data generated as part of high CPU usage monitoring tool is populated in the wrong file. There is no functional impact.

  • Fixed Issue 2305872: Downloaded Tech Support bundle does not contain the threaddump_top file

    The file name was changed from threaddump_top to threaddump.top, so the file was not included in tech support bundle due to name mismatch.

  • Fixed Issue 2298106: During NSX Manager upgrade, the UI is stuck at "Uploading File"

    During NSX Manager upgrade, the UI is stuck at "Uploading File" and you can see NSX file downloaded after the upload is complete.

  • Fixed Issue 2289996: When HA is enabled but management interface is not configured, DLR VMs go into split brain as HA flag sent to edge VM was set to "true"

    Edge VMs go into split brain condition when management interface is not configured/deleted (HA Enabled case).

  • Fixed Issue 2286288: In Edge UI, for EDGE-1 in grouping objects, when an IP address is given as a filter value, the ipsets that do not belong to edge-1 are also displayed

    If searching in any edge Grouping Objects- IP Sets for IPset using IP, the search results include all local edge IP Sets, which is wrong.

  • Fixed Issue 2266983: Unable to add a new ipsec site config as duplicate site is flagged where localIp, peerIp, localSubnets match but peerSubnets differ among 2 IPsec site configs

    Error seen where two sites have the same localIP, peerIP, localSubnet, peerSubnet tetrad. Unable to add a new ipsec site config for policy based IPsec having new subnets for peer.

  • Fixed Issue 2266098: NSX Manager not coming up after restore

    NSX management service is in STOPPED state. NSX related operations are affected as NSX Manager is not running.

  • Fixed Issue 2262778: EC certificates cannot be imported into NSX

    While importing EC certificate, error 2006 may be received. EC certificates will not be supported in NSX workflows.

  • Fixed Issue 2261838: The btmp file can grow to consume all available space on the log partition (/var/log), which may affect normal operation of the Edge and will prevent logs from being stored

    The /var/log partition shows as 100% used. Local logging is not possible.

  • Fixed Issue 2249307: The Locale ID on ESXi host is reset to default upon ESXi host reconnection to NSX Manager

    Missing DLR routes. DLR no longer routing traffic. Host receives the wrong Locale ID and the intended DLR routes are not retained.

  • Fixed Issue 2241434: Large number of snapshots taken in parallel could cause high stun time causing traffic outage

    Traffic outage when taking VM snapshots may be observed where one of the VMs being snapshotted is an NSX Edge VM.

Installation and Upgrade Known Issues

Before upgrading, please read the section Upgrade Notes, earlier in this document.

  • Issue 2001988: During NSX host cluster upgrade, Installation status in Host Preparation tab alternates between "not ready" and "installing" for the entire cluster when each host in the cluster is upgrading

    During NSX upgrade, clicking "upgrade available" for NSX prepared cluster triggers host upgrade. For clusters configured with DRS FULL AUTOMATIC, the installation status alternates between "installing" and "not ready", even though the hosts are upgraded in the background without issues.

    Workaround: This is a user interface issue and can be ignored. Wait for the host cluster upgrade to proceed.

  • Issue 1859572: During the uninstall of NSX VIBs version 6.3.x on ESXi hosts that are being managed by vCenter version 6.0.0, the host continues to stay in Maintenance mode
    If you are uninstalling NSX VIBs version 6.3.x on a cluster, the workflow involves putting the hosts into Maintenance mode, uninstalling the VIBs and then removing the hosts from Maintenance mode by the EAM service. However, if such hosts are managed by vCenter server version 6.0.0, then this results in the host being stuck in Maintenance mode post uninstalling the VIBs. The EAM service responsible for uninstalling the VIBs puts the host in Maintenance mode but fails to move the hosts out of Maintenance mode.

    Workaround: Manually move the host out of Maintenance mode. This issue will not be seen if the host is managed by vCenter server version 6.5a and above.

  • Issue 1263858: SSL VPN does not send upgrade notification to remote client

    SSL VPN gateway does not send an upgrade notification to users. The administrator has to manually communicate that the SSL VPN gateway (server) is updated to remote users and they must update their clients.

    Workaround: Users need to uninstall the older version of client and install the latest version manually.

  • Issue 2006028: Host upgrade may fail if vCenter Server system is rebooting during upgrade

    If the associated vCenter Server system is rebooted during a host upgrade, the host upgrade might fail and leave the host in maintenance mode. Clicking Resolve does not move the host out of maintenance mode. The cluster status is "Not Ready".

    Workaround: Exit the host from maintenance mode manually. Click "Not Ready" then "Resolve All" on the cluster.

  • Issue 2312793: etag value in http header has double quotes around it

    REST API will fail if using etag value coming into response.

    Workaround: Etag will continue to have double quotes around it in future versions. Fix automation script for handling double quotes with etag value.

  • Issue 2265909: No more support for double slash in REST API URI

    REST API calls are failing with ERROR 500: Internal Server Error. REST APIs will fail if URI contains double slash.

    Workaround: Remove double slash from URI and call API with single slash.

    • Issue 2005973: Routing daemon MSR loses all routing configuration after deleting a few gre tunnels and then doing a force sync of edge node from Management Plane

      This problem can occur on a edge with BGP sessions over GRE tunnels. When some of the GRE tunnels are deleted and then a force sync of the edge is done from MP, edge loses all routing configuration.

      Workaround: Reboot edge node.

    • Issue 2005900: Routing daemon MSR on Edge is stuck at 100% CPU when all GRE tunnels are flapped in an 8-way iBGP/multi-hop BGP ECMP scale topology

      This problem can occur in a scale topology where iBGP or multi-hop BGP is configured on ESG with multiple neighbors running over many GRE tunnels. When multiple GRE tunnels flap, MSR may get stuck indefinitely at 100% CPU.

      Workaround: Reboot edge node.

    • Issue 2233029: ESX does not support 10K routes

      ESX does not need to support 10K routes. By design, the maximum limit on ESX is 2K routes.

      Workaround: None.

    Security Services Known Issues
    • Issue 1648578: NSX forces the addition of cluster/network/storage when creating a new NetX host-based service instance
      When you create a new service instance from the vSphere Web Client for NetX host-based services such as Firewall, IDS, and IPS , you are forced to add cluster/network/storage even though these are not required.

      Workaround: When creating a new service instance, you may add any information for cluster/network/storage to fill out the fields. This will allow the creation of the service instance and you will be able to proceed as required.
