Important Information about NSX-T Data Center 3.2.0

Please be advised that the VMware NSX Team has identified an issue with Upgrade from previous versions to NSX-T Data Center 3.2.0 and has decided to withdraw the release from the download pages in favor of NSX-T Data Center 3.2.0.1.

Customers who have downloaded and deployed NSX-T Data Center 3.2.0 remain supported but are advised to upgrade to NSX-T Data Center 3.2.0.1.

What's New

NSX-T Data Center 3.2.0 is a major release offering many new features in all the verticals of NSX-T: networking, security, services and onboarding. Here are some of the major enhancements.

  • Switch agnostic distributed security: Ability to extend micro-segmentation to workloads deployed on vSphere networks.
  • Gateway Security: Enhanced L7 App IDs, Malware Detection and Sandboxing, URL filtering, User-ID firewall, TLS inspection (Tech Preview) and Intrusion Detection and Prevention Service (IDS/IPS).
  • Enhanced Distributed Security: Malware detection and Prevention, Behavioral IDS/IPS, enhanced application identities for L7 firewall.
  • Improved integration with NSX Advanced Load Balancer (formerly Avi): Install and configure NSX ALB (Avi) from NSX-T UI; Migrate NSX for vSphere LB to NSX ALB (Avi).
  • NSX for vSphere to NSX-T Migration: Major enhancements to the Migration Coordinator to extend coverage of supported NSX for vSphere topologies and provide flexibility on the target NSX-T topologies.
  • Improved protection against Log4j vulnerability: Updated Apache Log4j to version 2.16 to resolve CVE-2021-44228 and CVE-2021-45046. For more information on these vulnerabilities and their impact on VMware products, please see VMSA-2021-0028.

In addition to these features, many other capabilities are added in every area of the product.

Layer 2 Networking

  • Support dual NIC bonds on Windows physical servers - Connections using dual physical NIC (pNIC) bonds are now supported on physical servers. This allows configuration of active/active or active/standby bond. This feature is supported on VLAN and overlay networks.
  • NUMA-aware teaming policy - NSX now supports processing of the traffic on the same NUMA node as the pNICs used to leave ESXi. This feature enhances the performance in deployment leveraging teaming policies across multiple NUMA.
  • Enhanced Datapath new capabilities - Enhanced Datapath Switch now supports Distributed Firewall (DFW), Distributed Load-Balancer (DLB), and port mirroring capabilities.

Layer 3 Networking

  • Support L3 EVPN route server mode - ESXi is now capable of directly sending VXLAN traffic to the data center fabric routers bypassing the Edge node in the data path. In this deployment model, the Tier-0 SR (Service Router) hosted on the Edge Node is still necessary only to handle the control plane, i.e., advertising the connected prefixes through EVPN l2vpn address-family to the fabric. ESXi now supports ECMP towards multiple physical routers in the fabric and test the availability of the routers with BFD.
  • 5-tuple ECMP on ESXi and KVM - The distributed router (DR) hosted on ESXi now supports 5-tuple hashing algorithm when ECMP is enabled. With this feature, the hashing is based on IP address source, IP address destination, IP protocol, layer-4 port source, layer-4 port destination. This allows a better distribution of the traffic across all the available Service Routers (SRs).
  • Proxy ARP support on Active/Active Tier-0 Gateway - In simple topologies without a need for dynamic routing, a Tier-0 gateway in active/active HA mode can now be used, providing higher throughput.

Multicast

  • Support for Active/Active on Tier-0 SR for Multicast Traffic - NSX now supports ECMP of multicast traffic across multiple Tier-0 SRs (Service Routers), offering a better throughput for multicast traffic.

Edge Platform

  • UEFI support on Bare Metal Edge - NSX now supports the deployment of bare metal edge node on servers running in UEFI mode. This allows edge nodes to be deployed on a broader set of servers.

Distributed Firewall

  • Distributed Firewall supports VMs deployed on Distributed Port Groups on VDS switches - In previous releases, NSX could only enforce Distributed Security features for N-VDS switchports. Now you can leverage Distributed Firewall capabilities for VDS based VLAN networks without having to convert the switchport to N-VDS.
  • Support for dynamic tag criteria on Groups of IP Addresses.
  • Distributed Firewall Support for Physical servers - Redhat Enterprise Linux 8.0 operating system.
  • Addition of more Application IDs for L7 Firewall usage.
  • Malware Prevention for Distributed Firewall (E-W use case) - NSX Distributed Firewall now has zero-day malware detection and prevention capabilities using advanced machine learning techniques and sandboxing capabilities.
  • Configuration of AD Selective-Sync for IDFW - Identity firewall AD configuration now supports selectively adding OUs and users.
  • Identity Firewall Statistics - Enhanced the Security Overview dashboard to include Identity Firewall statistics for active users and active user sessions.

Distributed Intrusion Detection/Prevention System (D-IDPS)

  • Distributed IDS/IPS is supported for VMs deployed on Distributed Port Groups on VDS.
  • Distributed IDS/IPS now supports Behavior-based detection and prevention - A new class of IDS signatures is now available both on the distributed IDPS and on the edge. Rather than attempting to identify malware-specific behavior, these signatures attempt to identify network behaviors that could be associated to sign of a successful infection. This includes, for instance, the identification of Tor communication in the network, the presence of self-signed TLS certificates on high ports, or more sophisticated stateful detections such as the detection of beaconing behavior. This class of signatures is characterized by the severity level “informational”. If NSX NDR is enabled, further ML-based processing is applied on alerts produced by these signatures to prioritize cases that are very likely to be anomalous in the specific monitored environment.
  • Curation and Combination of Trustwave and VMware Signatures - NSX IDS/IPS signature set now allows access to a new IDS ruleset that is developed and curated by VMware to ensure high-security effectiveness and minimize the likelihood of false positives. The ruleset combines detections developed by third-party vendors such as Trustwave and Emerging Threats with a corpus of VMware-developed signatures and optimized for the NSX IDS engines.

Gateway Firewall

  • User Identity-based Access Control - Gateway Firewall introduces the following additional User Identity Firewall capabilities:
    1. For deployments where Active Directory is used as the user authentication system, NSX leverages Active Directory logs.
    2. For all other authentication systems, NSX can now leverage vRealize Log Insight based logs to identify User Identity to IP address mapping.
  • Enhanced set of L7 AppIDs - Gateway Firewall capabilities are enhanced to identify a more comprehensive number of Layer-7 applications.
  • TLS Inspection for both inbound and outbound traffic (🔎Tech Preview; not for production deployments) - More and more traffic is getting encrypted on the network. With the TLS inspection feature, you can now leverage NSX Gateway Firewall to do deep-packet inspection and threat detection and prevention services for encrypted traffic as well.
  • URL Filtering (includes categorization and reputation of URLs) - You can now control internet bound traffic based on the new URL Filtering feature. This feature allows you to control internet access based on the URL categories and as well as the reputation of the URLs. URL repository, including the categorization and reputation data, is updated on an ongoing basis for updated protection.
  • Malware Analysis and Sandboxing support - NSX Gateway Firewall now provides malware detection from known as well as zero-day malware using advanced machine learning techniques and sandboxing capabilities. The known malware data is updated on an ongoing basis. (Please see known issue 2888658 before deploying in live production deployments.)
  • Intrusion Detection and Prevention (🔎Tech Preview; not for production deployments) - For NSX Gateway Firewall, Intrusion Detection and Prevention capabilities (IPS) are introduced in a "Tech Preview" mode. You can try the feature set in non-production deployments.

New NSX Application Platform

NSX Application Platform - VMware NSX Application Platform is a new container based solution introduced in NSX-T 3.2.0 that provides a highly available, resilient, scale out architecture to deliver a set of core platform services which enables several new NSX features such as:

NSX Intelligence
NSX Metrics
NSX Network Detection and Response
NSX Malware Prevention

The NSX Application Platform deployment process is fully orchestrated through the NSX UI. Refer to the Deploying and Managing the VMware NSX Application Platform guide for more information on the infrastructure prerequisites and requirements for installation.

Network Detection and Response

  • VMware Network Detection and Response correlates IDPS, Malware and Anomaly events into intrusion campaigns that help identify threats and malicious activities on the network.
  • Correlation into threat campaigns rather than events, which allows SOC operators to focus on triaging only a small set of actionable threats.
  • Network Detection and Response collects IDPS events from Distributed IDPS, Malware events (malicious files only) from Gateway, and Network Anomaly events from NSX Intelligence.
    • Gateway IDPS (Tech Preview) events are not collected by NSX Network Detection and Response in NSX-T 3.2.
  • Network Detection and Response functionality runs in the cloud and is available in two cloud regions: US and EU.

Refer to the following for more information:

VPN

  • Enhanced Service level alarms for VPN - IPSec Service Status details.
  • Additional logging details for packet tracing - Display SPI and Exchange Information for IPSec.

Guest Introspection

  • Guest Introspection Enhancements - Guest Introspection provides a set of APIs in the data plane for consumption within the guest context. This enhancement ensures only users with appropriate entitlement are provided this access.
  • Additional OS support for GI - Guest Introspection now supports CentOS 8.2, RHEL 8.2, SLES15 SP1, Ubuntu 20.04.

Federation

NOTE: While NSX releases earlier than 3.2.0 supported onboarding of existing local manager sites, this onboarding support is delayed from 3.2.0 and will be re-introduced in a later point release of 3.2.

  • Support VM tag replication between Local Managers - During disaster recovery (DR), replicated VMs are restarted in the DR location. If the security policy is based on NSX VM tags, the replicated VMs in the DR location must have those NSX tags on the remote Local Manager at recovery time. NSX Federation 3.2 now supports VM tag replication between Local Managers. The tag replication policy is configurable only through API.
  • Federation communications monitoring - The location manager page now offers a view on the latency and usage of the channels between Global Managers and Local Managers. This provides a better visibility of the health between the different components of federation.
  • Firewall Drafts - Draft of the security policies are now available on Global Manager. This includes support for auto-drafts and manual drafts.
  • Global Manager LDAP Support - Global Manager now supports configuration of LDAP sources for Role-Based Access Control (RBAC) similarly to support on Local Managers.

Container Networking and Security

  • Antrea to NSX-T Integration - Added the ability to define Antrea Network Policies from the NSX-T Distributed Firewall UI. Policies are applied on K8s clusters running Antrea 1.3.1-1.2.2 using the interworking controller. Also adds inventory collection: K8s Objects like Pods, Namespaces & services are collected in NSX-T inventory and tagged so that they can be selected in DFW Policies. Antrea Traceflow can now be controlled from the NSX-T Traceflow UI page, and Log bundles can be collected from K8s clusters using Antrea. There is no mandatory requirement to have NSX-T data-plane enabled on your K8s Antrea cluster nodes.
  • Grouping Enhancements - Added support for Antrea container objects. Added support for Not In operator on segment port tag criteria. Adds support for AND operator between group membership criteria involving segments and segment ports.

Load Balancing

  • VMware NSX Advanced Load Balancer (Avi) Installation through NSX - VMware NSX Advanced Load Balancer (Avi) Controllers can now be installed through the NSX-T Manager UI, which provides a single pane for installation of all NSX components.
  • Cross-Launch VMware NSX Advanced Load Balancer (Avi) UI from NSX-T Manager UI - Launch VMware NSX ALB (Avi) UI from the NSX-T Manager for advanced features.
  • Advanced Load Balancer (Avi) User Interfaces displayed within NSX – Configure VMware NSX Advanced Load Balancer (Avi) from within NSX Manager.
  • Migrate Load Balancing from NSX for vSphere to VMware NSX Advanced Load Balancer (Avi) – Migrate Load Balancers to VMware NSX ALB (Avi) when using the Bring your own Topology model with the Migration Coordinator.
  • NSX-T native Load Balancer - Load balancing features would not be added or enhanced going forward. NSX-T platform enhancements would not be extended to the NSX-T native load balancer.
  • Load Balancing Recommendation
    • If you are using Load Balancing in NSX-T, you are advised to migrate to VMware NSX Advanced Load Balancer (Avi), which provides a superset of the NSX-T load balancing functionality.
    • If you have purchased NSX Data Center Advanced, NSX Data Center Enterprise Plus, NSX Advanced, or NSX Enterprise, you are entitled to the Basic edition of VMware NSX Advanced Load Balancer (Avi), which has feature parity with NSX-T LB.
    • It is recommended that you purchase VMware NSX Advanced Load Balancer (Avi) Enterprise to unlock enterprise grade load balancing, GSLB, advanced analytics, container ingress, application security and WAF.

Note: It is recommended that new deployments with NSX-T Data Center take advantage of VMware NSX Advanced Load Balancer (Avi) using release v20.1.6 or later and not use the native NSX-T Load Balancer.

For more information:

NSX Cloud

  • Extended OS Support on NSX Cloud - NSX Cloud now supports the following OS, in addition to the ones already supported:
    • Ubuntu 20.04
    • RHEL 8.next
  • NSX Cloud support of Advanced Security (Layer 7) features on PCG (🔎Tech Preview; not for production deployments) - NSX Cloud offers some Advanced Security (Layer 7) capability on the PCG on both Azure and AWS, enabling you to benefit from application layer security for your workloads in the public Cloud. You can try the feature set in non-production deployments.
  • NSX Cloud support of IDFW for single user VDI (🔎Tech Preview; not for production deployments) - NSX Cloud offers identity firewall to offer user based security for VDI deployment. It will be able to associate to a VM a security profile mapped to the user connected, hence simplifying security management and strengthening security. You can try the feature set in non-production deployments.

Operations and Monitoring

  • Command del nsx to clean up NSX on a Physical / Bare Metal Server - In continuation with the del nsx feature support on ESX servers, a CLI command del nsx is available to remove NSX from a Physical / Bare Metal Server running a Linux OS. If you have a Physical / Bare Metal Server with NSX VIBs in a stale state and are unable to uninstall NSX from that host, you can use the CLI command del nsx for a guided step-by-step process to remove NSX from that host and bring it back to a clean state so NSX can be reinstalled.
  • Live Traffic Analysis through NSX Manager UI - The Live Traffic Analysis feature is now available on the NSX Manager UI, allowing you to easily analyze the live traffic flows across data centers. This features provides a unified approach of diagnosis by combining Traceflow, and packet capture. You can perform both actions in one shot - trace live packets and perform packet capture at source. Live Traffic Analysis helps in accurately determining issues in network traffic and provides the ability to perform the analysis on specific flows to avoid noise.
  • Selective Port Mirroring - Enhanced mirroring with flow based filtering capability and reduced resource requirements. You can now focus on pertinent flows for effective troubleshooting.
  • Fabric MTU Configuration Check - An on-demand and periodic MTU check will be available on the NSX Manager UI to verify MTU configuration for overlay network; alerts are raised for MTU mismatches.
  • Traceflow support on VLAN backed Logical Network - You can perform Traceflow on a VLAN backed logical network. This feature is available through the API.
  • Improved Logging - Improved logging by detecting and suppressing repetitive log messages emitted too frequently to prevent important log messages from being lost or overshadowed.
  • Improved CLI guide and additional commands - Introduced a set of new CLI commands mapped with the UI constructs (Policy) like for instance segment. This allows for simpler consumption of the CLI for users. A completely refactored CLI guide is also introduced to simplify consumption.

Monitoring

  • Time-Series Monitoring - Provides the ability to collect and store metrics for a longer duration up to one year with NSX Application Platform. Time-Series metrics helps to monitor the trend in key performance indicators, performs before and after analysis, and provides the historical context helpful in troubleshooting. Time-series metrics is available for Edge Node, Tier-0 and Tier-1 Gateways, NSX Manager, NSX Application Platform and security features, which includes TLS Inspection, IDPS, Gateway Firewall. These time-series metrics are available through NSX-T APIs and a subset of these metrics are also available on the NSX Manager UI.

Usability and User Interface

  • Customize login messages and banners - You can configure and customize the login message from NSX Manager and specify the mandatory fields the user needs to accept before logging in.
  • Search and Filter Enhancements - Enhanced the existing search and filtering capability in the NSX UI. An initial screen displays the possible search phrases and the most recently searched items. A separate panel is available for 'Advanced Search' that allows users to customize and configure 'Searches'. Search queries now surface information from tags and alarms.
  • VPAT - Fixes to bridge the accessibility gap in the product.
  • NSX Topology - Visualize the underlying fabric associated with gateways. This feature provides you the ability to visualize the edge clusters, host switch configuration, and gather details on the host and edge configurations.
  • Improve Usability of Object Selector in UI - This feature provides the ability to select multiple objects that are in the same category. Additionally, you can select all the objects.
  • Revamped Security Overview - Revamped the Security Overview page to provide a holistic view of the security configurations. You can view 'Threats and Responses' across different features as well as view the existing configuration and capacity of the system.
  • NSX-T UI Integrated in vCenter - NSX-T can now be installed and configured via the vCenter UI with the vCenter plugin for NSX-T. This feature is supported ONLY from vCenter 7.0U3 onwards.
  • Deployment wizard of NSX-T for common use cases - When installed via the vCenter plugin, NSX-T can now enable NSX-T features based on common use cases, allowing users to quickly turn on NSX-T features leveraging the deployment wizards. This release supports two wizards, one to enable Security features of NSX and the other to enable Virtual Networking features of NSX.

Policy

  • NSX Manager to NSX Policy Promotion Tool - Provides ability to promote existing configuration from NSX Manager to NSX Policy without data path disruption or deletion/recreation of existing objects. Once the NSX Manager objects are promoted to NSX Policy, the NSX Manager objects are set to read-only through the Manager UI/API, and you can then interact with the same objects through NSX Policy UI/API.

AAA and Platform Security

  • Certificate Management Enhancements for TLS Inspection (🔎Tech Preview; not for production deployments) - With the introduction of the TLS Inspection feature, certificate management now supports addition and modification of certification bundles and the ability to generate CA certificates to be used with the TLS Inspection feature. In addition, the general certificate management UI can carry modifications that simplify import/export of certificates.
  • High Availability and Scale enhancements for LDAP Integration - LDAP configuration now supports the configuration of multiple LDAP servers per domain and support for 'trust' of multiple certificates associated with different LDAP servers per domain.

Scale

  • Increased Scale - There are several increases in the supported scale for the largest deployments. For details on scale changes, see the VMware Configuration Maximums tool.

Licensing

  • License Enforcement - NSX-T now ensures that users are license-compliant by restricting access to features based on license edition. New users are able to access only those features that are available in the edition that they have purchased. Existing users who have used features that are not in their license edition are restricted to only viewing the objects; create and edit will be disallowed.
  • New Licenses - Added support for new VMware NSX Gateway Firewall and NSX Federation Add-On and continues to support NSX Data Center licenses (Standard, Professional, Advanced, Enterprise Plus, Remote Office Branch Office) introduced in June 2018, and previous VMware NSX for vSphere license keys. See VMware knowledge base article 52462 for more information about NSX licenses.

NSX Data Center for vSphere to NSX-T Data Center Migration

  • Migration for VMware Integrated OpenStack - Added the capability to perform NSX for vSphere to NSX-T migration in VIO environments without breaking the OpenStack representation of the objects. This feature requires the support of migration capabilities by the VMware Integrated OpenStack version that is used.
  • Bring your own Topology - The Migration Coordinator extends its model to offer migration between NSX for vSphere and a user defined topology in NSX-T. This offers more flexibility for users to define their NSX-T topology and extends the number of topologies which can be migrated from NSX for vSphere to NSX-T.

    This feature can only be used for the configuration migration in order to enable lift and shift or as part of the complete workflow doing in place migration.

  • Support OSPF Migration for fixed topologies - The Migration Coordinator supports fixed topologies with OSPF (instead of BGP and static). This allows users wanting to use fixed topologies (and not BYOT) to do so even when they have OSP configured for N/S connectivity between ESG and top of rack (OSPF between ESG and DLR was already supported and replaced by NSX-T internal routing).
  • Increased scale for Migration Coordinator - The Migration Coordinator scale is increasing in order to cover larger environments and come closer to NSX for vSphere maximum scale.
  • Migration of Guest Introspection - NSX for vSphere to NSX-T migration for GI is now added in migration coordinator. You can use this feature provided the partner vendor also supports the migration coordinator.
  • IDFW/RDSH Migration - The migration coordinator now supports Identity based firewall configurations.

Tech Preview Features

NSX-T Data Center 3.2 offers several features for your technical preview. Technical preview features are not supported by VMware for production use. They are not fully tested and some functionality might not work as expected. However, these previews help VMware improve current NSX-T functionality and develop future enhancements.

For details about these technical preview features, see the available documentation provided in the NSX-T Data Center 3.2 Administration Guide. Links are provided in the following list that briefly describes these technical preview features. The topics will have Technical Preview in their titles.

Inclusive Terminology

At VMware, we value inclusion and diversity. To promote these principles within our customer, partner, and internal communities, there is a company-wide effort to replace non-inclusive language in our products. Problematic terminology in the NSX-T Data Center UI, documentation, APIs, CLIs, and logs are in the process of being replaced with more inclusive alternatives. For example, the non-inclusive term disabled has been replaced with the alternative deactivate.

Compatibility and System Requirements

For compatibility and system requirements information, see the VMware Product Interoperability Matrices and the NSX-T Data Center Installation Guide.

Feature / API Deprecations and Behavior Changes

Deprecation announcement for NSX Manager APIs and NSX Advanced UIs

NSX-T has two methods of configuring logical networking and security: Manager mode and Policy mode. The Manager API contains URIs that begin with /api, and the Policy API contains URIs that begin with /policy/api.

Please be aware that VMware intends to remove support of the NSX-T Manager APIs and NSX Advanced UIs in an upcoming NSX-T major or minor release, which will be generally available no sooner than one year from the date of this message, 12/16/2021. NSX-T Manager APIs that are planned to be removed are marked with "deprecated" in the NSX Data Center API Guide, with guidance on replacement APIs.

It is recommended that new deployments of NSX-T take advantage of the NSX Policy APIs and NSX Policy UIs. For deployments currently leveraging NSX Manager APIs and NSX Advanced UIs, please refer to the NSX Manager for the Manager to Policy Objects Promotion page and NSX Data Center API Guide to aid in the transition.

N-VDS NSX-T Host Switch Deprecation Announcement

NSX-T 3.0.0 and later can run on the vSphere VDS switch version 7.0 and later. This provides a tighter integration with vSphere and easier NSX-T adoption for customers adding NSX-T to their vSphere environment.

Please be aware that VMware intends to remove support of the NSX-T N-VDS virtual switch on ESXi hosts in an upcoming NSX-T release, which will be generally available no sooner than one year from the date this message was announced (April 17, 2021). N-VDS will remain the supported virtual switch on KVM, NSX-T Edge nodes, native public cloud NSX agents, and bare metal workloads.

It is recommended that new deployments of NSX-T and vSphere take advantage of this close integration and deploy using VDS switch version 7.0 and later. In addition, for existing deployments of NSX-T that use the N-VDS on ESXi hosts, VMware recommends moving toward the use of NSX-T on VDS. To make this process easy, VMware has provided both a CLI based switch migration tool, which was first made available in NSX-T 3.0.2, and a GUI based Upgrade Readiness Tool, which was first made available in NSX-T 3.1.1 (see NSX documentation for more details on these tools).

NOTE: In NSX-T 3.2.0, the N-VDS to VDS migration tool is unavailable. Customers wanting to migrate their workloads from N-VDS to VDS in this release may do so by manually migrating the workloads.

The following deployment considerations are recommended when moving from N-VDS to VDS:

  • The N-VDS and VDS APIs are different, and the backing type for VM and vmKernel interface APIs for the N-VDS and VDS switches are also different. As you move to use VDS in your environment, you will have to invoke the VDS APIs instead of N-VDS APIs. This ecosystem change will have to be made before converting the N-VDS to VDS. See knowledge base article 79872 for more details. Note: There are no changes to N-VDS or VDS APIs.
  • VDS is configured through vCenter. N-VDS is vCenter independent. With NSX-T support on VDS and the eventual deprecation of N-VDS, NSX-T will be closely tied to vCenter and vCenter will be required to enable NSX in vSphere environments.

OpenStack and KVM

The 3.x release series is the final series to support KVM and non-VIO OpenStack distributions including but not limited to RedHat OpenStack Platform, Canonical/Ubuntu OpenStack, SUSE OpenStack Cloud, Mirantis OpenStack and community based OpenStack, which does not have a specific vendor. Customers using non-VIO OpenStack with NSX are encouraged to consider vRealize Automation or VMware Cloud Director as a replacement for their deployments.

Deprecation Announcement for NSX-T Load Balancing APIs

NSX-T Load Balancer APIs would be marked as deprecated. This would apply to all APIs containing URIs that begin with /policy/api/v1/infra/lb-

Please be aware that VMware intends to remove support of the NSX-T Load Balancer in an upcoming NSX-T release, which will be generally available no sooner than one year from the date this message was announced (December 16, 2021). NSX-T Manager APIs that are planned to be removed are marked with "deprecated" in the NSX Data Center API Guide.

It is recommended that new deployments with NSX-T Data Center take advantage of VMware NSX Advanced Load Balancer (Avi) using release v20.1.6 or later.

Note: API deprecation does not apply to the Distributed Load Balancer.

Alarms

  • NSX Intelligence Communications alarms replaced by NSX Application Platform Communication alarms.
  • NSX Intelligence Health alarms replaced by NSX Application Platform Health alarms.
  • DNS - Fowarder Disabled alarm.
  • Infrastructure Service - Edge Service Status Down alarm will be covered as part of Edge Service Status Change alarm.
  • Transport Node Health - NVDS Uplink Down alarm got replaced by Transport Node Uplink Down alarm.

Live Traffic Analysis API Deprecation and Changes

  • Live Traffic Analysis MP APIs are marked as deprecated in NSX-T 3.2.0.
  • The Packet Count option is removed from Live Traffic Analysis in NSX-T 3.2.0. Live Traffic Analysis will continue to support tracing and packet capture.
  • The following fields and types are removed:
    • Policy API: Fields - count_config, Types - PolicyCountObservation
    • MP API: Fields - count_config, count_results, Types - CountActionConfig, LiveTraceActionType (COUNT: An unsupported action), CountActionArgument, CountResult, CountObservation, BaseCountObservation

API Deprecations and Behavior Changes

  • NSX deprecated APIs removal - The following APIs have been deprecated more than one year ago and are removed in NSX-T 3.2.0.

Resolved Issues

  • Fixed Issue 2685550: FW Rule realization status is always shown as "In Progress" when applied to bridged segments.

    When applying FW Rules to an NSGroup that contains bridged segments as one of its members, realization status will always be shown as in progress. You won't be able to check the realization status of FW Rules applied to bridged segments.

  • Fixed Issue 2805986: Unable to deploy NSX-T managed edge VM.

    NSX-T Edge deployment fails when done using ESX UI.

  • Fixed Issue 2643749: Unable to nest group from custom region created on specific site into group that belongs to system created site specific region.

    You will not see the group created in site specific custom region while selecting child group as a member for the group in the system created region with the same location.

  • Fixed Issue 2638673: SRIOV vNICs for VMs are not discovered by inventory.

    SRIOV vNICs are not listed in Add new SPAN session dialog. You will not see SRIOV vNICs when adding new SPAN session.

  • Fixed Issue 2622576: Failures due to duplicate configuration are not propagated correctly to user.

    While onboarding is in progress, you see an "Onboarding Failure" message.

  • Fixed Issue 2587257: In some cases, PMTU packet sent by NSX-T edge is ignored upon receipt at the destination.

    PMTU discovery fails resulting in fragmentation and reassembly, and packet drop. This results in performance drop or outage in traffic.

  • Fixed Issue 2482580: IDFW/IDS configuration is not updated when an IDFW/IDS cluster is deleted from vCenter.

    When a cluster with IDFW/IDS enabled is deleted from vCenter, the NSX management plane is not notified of the necessary updates. This results in accurate count of IDFW/IDS enabled clusters. There is no functional impact. Only the count of the enabled clusters is wrong.

  • Fixed Issue 2610851: Namespaces, Compute Collection, L2VPN Service grid filtering might return no data for few combinations of resource type filters.

    Applying multiple filters for a few types at the same time returned no results even though data is available with matching criteria. It is not a common scenario and filter will fail only these grids for the following combinations of filter attribute: For Namespaces grid ==> On Cluster Name and Pods Name filter For Network Topology page ==> On L2VPN service applying a remote ip filter For Compute Collection ==> On ComputeManager filter

  • Fixed Issue 2685550: FW Rule realization status is always shown as "In Progress" when applied to bridged segments.

    When applying FW Rules to an NSGroup that contains bridged segments as one of its members, realization status will always be shown as in progress. You won't be able to check the realization status of FW Rules applied to bridged segments.

  • Fixed Issue 2730109: When Edge is powering ON, Edge tries to make OSPF neighborship with the peer using its routerlink IP address as a OSPF RouterID though loop back is present.

    After reloading Edge, OSPF selects the downlink IP-address (the higher IP-address) as router-id until it receives the OSPF router-id configuration due to the configuration sequencing order. The neighbour entry with older router-id will eventually become stale entry upon receiving OSPF HELLO with new router-id and get expired after dead timer expiry on the peer.

  • Fixed Issue 2631703: When doing backup/restore of an appliance with vIDM integration, vIDM configuration will break.

    Typically when an environment has been both upgraded and/or restored, attempting to restore an appliance where vIDM integration is up and running will cause that integration to break and you will to have to reconfigure.

  • Fixed Issue 2655539: Host names are not updated on the Location Manager page of the Global Manager UI when updating the host names using the CLI.

    The old host name is shown.

  • Fixed Issue 2682480: Possible false alarm for NCP health status.

    The NCP health status alarm may be unreliable in the sense that it is raised when NCP system is healthy.

  • Fixed Issue 2550492: During an upgrade, the message, "The credentials were incorrect or the account specified has been locked" is displayed temporarily and the system recovers automatically.

    Transient error message during upgrade.

  • Fixed Issue 2521230: BFD status displayed under ‘get bgp neighbor summary’ may not reflect the latest BFD session status correctly.

    BGP and BFD can set up their sessions independently. As part of ‘get bgp neighbor summary’ BGP also displays the BFD state. If the BGP is down, it will not process any BFD notifications and will continue to show the last known state. This could lead to displaying stale state for the BFD.

  • Fixed Issue 2625009: Inter-SR iBGP sessions keep flapping, when intermediate routers or physical NICs have lower or equal MTU as the inter-SR port.

    This can impact inter-site connectivity in Federation topologies.

  • Fixed Issue 2662225: When active edge node becomes non-active edge node during flowing S-N traffic stream, traffic loss is experienced.

    Current S->N stream is running on multicast active node. The preferred route on TOR to source should be through the multicast active edge node only. Bringing up another edge can take over multicast active node (lower rank edge is active multicast node). Current S->N traffic will experience loss up to four minutes. This is will not impact new stream or if current stream is stopped and started again.

  • Fixed Issue 2587513: Policy shows error when multiple VLAN ranges are configured in bridge profile binding.

    You will see an "INVALID VLAN IDs" error message.

  • Fixed Issue 2606452: Onboarding is blocked when trying to onboard via API.

    Onboarding API fails with the error message, "Default transport zone not found at site".

  • Fixed Issue 2649240: Deletion is slow when a large number of entities are deleted using individual delete APIs.

    It takes significant time to complete the deletion process.

  • Fixed Issue 2649499: Firewall rule creation takes a long time when individual rules are created one after the other.

    Slow API takes more time to create rules.

  • Fixed Issue 2652418: Slow deletion when large number of entities are deleted.

    Deletion will be slower.

  • Fixed Issue 2658687: Global Manager switchover API reports failure when transaction fails, but the failover happens.

    API fails, but Global Manager switchover completes.

  • Fixed Issue 2679614: When the API certificate is replaced on the Local Manager, the Global Manager's UI will display the message, "General Error has occurred."

    When the API certificate is replaced on the Local Manager, the Global Manager's UI will display the message, "General Error has occurred."

  • Fixed Issue 2557287: TNP updates done after backup are not restored.

    You won't see any TNP updates done after backup on a restored appliance.

  • Fixed Issue 2858893: Service Deployment cleanup fails for Clustered-based deployment.

    No functional impact. Failure to clean up Service if trying to unregister ServiceDefinion with dangling ServiceDeployment or Instances. Have to manually/forcefully clean up from db.

  • Fixed Issue 2692344: If you delete the Avi Enforcement point, it deletes all the realized objects from the policy, which deletes all default object’s realized entities from the policy. Adding new enforcement point fails to re-sync the default object from the Avi Controller.

    You will not be able to use the system-default objects after deletion and recreation of the Enforcement point of AVIConnectionInfo.

Known Issues

  • Issue 2355113: Workload VMs running RedHat and CentOS on Azure accelerated networking instances is not supported.

    In Azure when accelerated networking is enabled on RedHat or CentOS based OS's and with NSX Agent installed the ethernet interface does not obtain an IP address.

    Workaround: Disable accelerated networking for RedHat and CentOS based OS.

  • Issue 2283559: /routing-table and /forwarding-table MP APIs return an error if the edge has 65k+ routes for RIB and 100k+ routes for FIB

    If the edge has 65k+ routes for RIB and 100k+ routes for FIB, the request from MP to Edge takes more than 10 seconds and results in a timeout. This is a read-only API and has an impact only if they need to download the 65k+ routes for RIB and 100k+ routes for FIB using API/UI.

    Workaround: There are two options to fetch the RIB/FIB. These APIs support filtering options based on network prefixes or type of route. Use these options to download the routes of interest. CLI support in case the entire RIB/FIB table is needed and there is no timeout for the same.

  • Issue 2693576: Transport Node shows "NSX Install Failed" after KVM RHEL 7.9 upgrade to RHEL 8.2​.

    After RHEL 7.9 upgrade to 8.2, dependencies nsx-opsagent and nsx-cli are missing, Host is marked as install failed. Resolving the failure from the UI doesn't work: Failed to install software on host. Unresolved dependencies: [PyYAML, python-mako, python-netaddr, python3]

    Workaround: Manually install NSX RHEL 8.2 vibs after host OS upgrade and then resolve it from the UI.

  • Issue 2628503: DFW rule remains applied even after forcefully deleting the manager nsgroup.

    Workaround: Do not forcefully delete an nsgroup that is still used by a DFW rule. Instead, make the nsgroup empty or delete the DFW rule.

  • Issue 2684574: If the edge has 6K+ routes for Database and Routes, the Policy API times out.

    These Policy APIs for the OSPF database and OSPF routes return an error if the edge has 6K+ routes: /tier-0s/<tier-0s-id>/locale-services/<locale-service-id>/ospf/routes /tier-0s/<tier-0s-id>/locale-services/<locale-service-id>/ospf/routes?format=csv /tier-0s/<tier-0s-id>/locale-services/<locale-service-id>/ospf/database /tier-0s/<tier-0s-id>/locale-services/<locale-service-id>/ospf/database?format=csv If the edge has 6K+ routes for Database and Routes, the Policy API times out. This is a read-only API and has an impact only if the API/UI is used to download 6k+ routes for OSPF routes and database.

    Workaround: Use the CLI commands to retrieve the information from the edge.

  • Issue 2663483: The single-node NSX Manager will disconnect from the rest of the NSX Federation environment if you replace the APH-AR certificate on that NSX Manager.

    This issue is seen only with NSX Federation and with the single node NSX Manager Cluster. The single-node NSX Manager will disconnect from the rest of the NSX Federation environment if you replace the APH-AR certificate on that NSX Manager.

    Workaround: Single-node NSX Manager cluster deployment is not a supported deployment option, so have three-node NSX Manager cluster.

  • Issue 2636771: Search can return resource when a resource tagged with multiple tag pairs, and tag and scope match with any value of tag and scope.

    This affects search query with condition on tag and scope. Filter may return extra data if tag and scope match with any pair.

    Workaround: None.

  • Issue 2668717: Intermittent traffic loss might be observed for E-W routing between the vRA created networks connected to segments sharing Tier-1.

    In cases where vRA creates multiple segments and connects to a shared ESG, V2T will convert such a topology to a shared Tier-1 connected to all segments on the NSX-T side. During the host migration window, intermittent traffic loss might be observed for E-W traffic between workloads connected to the segments sharing the Tier-1.

    Workaround: None.

  • Issue 2490064: Attempting to disable VMware Identity Manager with "External LB" toggled on does not work.

    After enabling VMware Identity Manager integration on NSX with "External LB", if you attempt to then disable integration by switching "External LB" off, after about a minute, the initial configuration will reappear and overwrite local changes.

    Workaround: When attempting to disable vIDM, do not toggle the External LB flag off; only toggle off vIDM Integration. This will cause that config to be saved to the database and synced to the other nodes.

  • Issue 2526769: Restore fails on multi-node cluster.

    When starting a restore on a multi-node cluster, restore fails and you will have to redeploy the appliance.

    Workaround: Deploy a new setup (one node cluster) and start the restore.

  • Issue 2534933: Certificates that have LDAP based CDPs (CRL Distribution Point) fail to apply as tomcat/cluster certs.

    You can't use CA-signed certificates that have LDAP CDPs as cluster/tomcat certificate.

    Workaround: There are two options.

    1. Use a certificate that has HTTP-based CDP.
    2. Disable CRL checking using PUT https://<manager>/api/v1/global-configs/SecurityGlobalConfig API (In the payload for PUT, make sure to have "crl_checking_enabled" as false.)
  • Issue 2566121: Wrong error message, "Some appliance components are not functioning properly" is displayed when server is overloaded.

    When there are too many API calls made to NSX, UI/API shows error, "Some appliance components are not functioning properly" instead of "server is overloaded."

    Workaround: None.

  • Issue 2613113: If onboarding is in progress, and restore of Local Manager is done, the status on Global Manager does not change from IN_PROGRESS.

    UI shows IN_PROGRESS in Global Manager for Local Manager onboarding. Configuration of the restored site cannot be imported.

    Workaround: Restart the Global Manager cluster, one node at a time.

  • Issue 2690457: When joining an MP to an MP cluster where publish_fqdns is set on the MP cluster and where the external DNS server is not configured properly, the proton service may not restart properly on the joining node.

    The joining manager will not work and the UI will not be available.

    Workaround: Configure the external DNS server with forward and reverse DNS entries for all Manager nodes.

  • Issue 2574281: Policy will only allow a maximum of 500 VPN Sessions.

    NSX claims support of 512 VPN Sessions per edge in the large form factor, however, due to Policy doing auto plumbing of security policies, Policy will only allow a maximum of 500 VPN Sessions. Upon configuring the 501st VPN session on Tier0, the following error message is shown: {'httpStatus': 'BAD_REQUEST', 'error_code': 500230, 'module_name': 'Policy', 'error_message': 'GatewayPolicy path=[/infra/domains/default/gateway-policies/VPN_SYSTEM_GATEWAY_POLICY] has more than 1,000 allowed rules per Gateway path=[/infra/tier-0s/inc_1_tier_0_1].'}

    Workaround: Use Management Plane APIs to create additional VPN Sessions.

  • Issue 2658092: Onboarding fails when NSX Intelligence is configured on Local Manager.

    Onboarding fails with a principal identity error. and you cannot onboard a system with principal identity user.

    Workaround: Create a temporary principal identity user with the same principal identity name that is used by NSX Intelligence.

  • Issue 2639424: Remediating a Host in a vLCM cluster with Host-based Deployment will fail after 95% Remediation Progress is completed.

    The remediation progress for a Host will be stuck at 95% and then Fail after 70 minute timeout is completed.

    Workaround: See VMware knowledge base article 81447.

  • Issue 2848614: When joining an MP to an MP cluster where publish_fqdns is set on the MP cluster and where the forward or reverse lookup entry missing in external the DNS server or the dns entry is missing for the joining node, forward or reverse alarms not generated for the joining node.

    Forward/reverse alarms are not generated for the joining node even though forward/reverse lookup entry is missing in the DNS server or the dns entry is missing for the joining node.

    Workaround: Configure the external DNS server for all Manager nodes with forward and reverse DNS entries.

  • Issue 2636420: Host will go to "NSX install skipped" state and cluster in "Failed" state post restore if "Remove NSX" is run on cluster post backup.

    "NSX Install Skipped" will be shown for host.

    Workaround: Following restore, you should have to run "Remove NSX" on the cluster again to achieve the state that was present following backup (not configured state).

  • Issue 2558576: Global Manager and Local Manager versions of a global profile definition can differ and might have an unknown behavior on Local Manager.

    Global DNS, session, or flood profiles created on Global Manager cannot be applied to a local group from UI, but can be applied from API. Hence, an API user can accidentally create profile binding maps and modify global entity on Local Manager.

    Workaround: Use the UI to configure system.

  • Issue 2491800: AR channel SSL certificates are not periodically checked for their validity, which could lead to using an expired/revoked certificate for an existing connection.

    The connection would be using an expired/revoked SSL.

    Workaround: Restart the APH on the Manager node to trigger a reconnection.

  • Issue 2561988: All IKE/IPSEC sessions are temporarily disrupted.

    Traffic outage will be seen for some time.

    Workaround: Modify the local endpoints in phases instead of all at the same time.

  • Issue 2566121: A UA node stopped accepting any New API calls, with "server is overloaded" message.

  • Issue 2882822: Temporary IPSets are not added to SecurityGroups used in EDGE Firewall rules / LB pool members during NSX for vSphere to NSX-T config migration.

    During migration, there may be a gap until the VMs/VIFs are discovered on NSX-T and are a part of the SGs to which they are applicable to via static/dynamic memberships. This can lead to traffic being dropped or allowed contrary to the Edge Firewall rules in the period between the North/South Cutover (N/S traffic going through NSX-T gateway) until the end of the migration.

    Workaround: Add a fake DFW rule in which the source / destination contains all the Security Groups consumed in the Edge FW. Another option is to move Edge Firewall rules source and destination to IPsets before the migration.

  • Issue 2884070: If there is a mismatch of MTU setting between NSX-T edge uplink and peering router, OSPF neighbor-ship gets stuck in Exstart state. During NSX for vSphere to NSX-T migration, the MTU is not automatically migrated so a mismatch can impact dataplane during North/South Edge cutover.

    Workaround: Update EdgeTN by disconnecting the Segments from its interfaces and re-connecting them.

  • Issue 2885330: Effective member not shown for AD group.

    Effective members of AD group not displayed. No datapath impact.

    Workaround: None.

  • Issue 2885552: If you have created an LDAP Identity Source that uses OpenLDAP, and there is more than one LDAP server defined, only the first server is used.

    If the first LDAP server becomes unavailable, authentication fails, instead of trying the rest of the configured OpenLDAP server(s).

    Workaround: If it is possible to place a load balancer in front of the OpenLDAP servers and configure NSX with the virtual IP of the load balancer, you can have high availability.

  • Issue 2886210: During restore, if the VC is down, a Backup/Restore dialog will appear telling the user to ensure that VC is up and running, however the IP address of the VC is not shown.
