What’s New in NSX-T 3.1.1

  • NSX-T Data Center 3.1.1 provides a variety of new features to offer new functionalities for virtualized networking and security for private, public, and multi-clouds.
  • Highlights include new features and enhancements in the following focus areas.

What’s New in NSX-T 3.1.1: L3 Networking

  • OSPFv2 Support on Tier-0 Gateways
    • NSX-T Data Center now supports OSPF version 2 as a dynamic routing protocol between Tier-0 gateways and physical routers.
      • OSPF can be enabled only on external interfaces and can all be in the same OSPF area (standard area or NSSA), even across multiple Edge Nodes.
      • This simplifies migration from the existing NSX for vSphere deployment already using OSPF to NSX-T Data Center.

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

  • Support of Universal Objects Migration for a Single Site
    • You can migrate your NSX Data Center for vSphere environment deployed with a single NSX Manager in Primary mode (not secondary). As this is a single NSX deployment, the objects (local and universal) are migrated to local objects on a local NSX-T.  This feature does not support cross-vCenter environments with Primary and Secondary NSX Managers.
  • Migration of NSX-V Environment with vRealize Automation – Phase 2
    • The Migration Coordinator interacts with vRealize Automation (vRA) to migrate environments where vRealize Automation provides automation capabilities. This release adds additional topologies and use cases to those already supported in NSX-T 3.1.0.
  • Modular Migration for Hosts and Distributed Firewall
    • The NSX-T Migration Coordinator adds a new mode to migrate only the distributed firewall configuration and the hosts, leaving the logical topology(L3 topology, services) for you to complete.
      • You can benefit from the in-place migration offered by the Migration Coordinator (hosts moved from NSX-V to NSX-T while going through maintenance mode, firewall states and memberships maintained, layer 2 extended between NSX for vSphere and NSX-T during migration) that lets you (or a third party automation) deploy the Tier-0/Tier-1 gateways and relative services, hence giving greater flexibility in terms of topologies. This feature is available from UI and API.
  • Modular Migration for Distributed Firewall available from UI
    •  The NSX-T user interface now exposes the Modular Migration of firewall rules.
    • This feature was introduced in 3.1.0 (API only) and allows the migration of firewall configurations, memberships and state from an NSX Data Center for vSphere environment to an NSX-T Data Center environment.
      • This feature simplifies lift-and-shift migration where you vMotion VMs between an environment with hosts with NSX for vSphere and another environment with hosts with NSX-T by migrating firewall rules and keeping states and memberships (hence maintaining security between VMs in the old environment and the new one).
  • Fully Validated Scenario for Lift and Shift Leveraging vMotion, Distributed Firewall Migration and L2 Extension with Bridging
    • This feature supports the complete scenario for migration between two parallel environments (lift and shift) leveraging NSX-T bridge to extend L2 between NSX for vSphere and NSX-T, the Modular Distributed Firewall.

Identity Firewall in NSX-T 3.1.1

  • NSX Policy API support for Identity Firewall configuration – Setup of Active Directory, for use in Identity Firewall rules, can now be configured through NSX Policy API (https://<nsx-mgr>/policy/api/v1/infra/firewall-identity-stores), equivalent to existing NSX Manager API (https://<nsx-mgr>/api/v1/directory/domains).

Advanced Load Balancer Integration

  •  Support Policy API for Avi Configuration
    • The NSX Policy API can be used to manage the NSX Advanced Load Balancer configurations of virtual services and their dependent objects.
      • The unique object types are exposed via the https://<nsx-mgr>/policy/api/v1/infra/alb-<objecttype> endpoints.
  • Service Insertion Phase 2
    • ​This feature supports the Transparent LB in NSX-T advanced load balancer (Avi).
      • Avi sends the load balanced traffic to the servers with the client’s IP as the source IP.
      • This feature leverages service insertion to redirect the return traffic back to the service engine to provide transparent load balancing without requiring any server side modification.

Edge Platform and Services

  • DHCPv4 Relay on Service Interface
    • Tier-0 and Tier-1 Gateways support DHCPv4 Relay on Service Interfaces, enabling a 3rd party DHCP server to be located on a physical network

AAA and Platform Security

  • Guest Users – Local User accounts: NSX customers integrate their existing corporate identity store to onboard users for normal operations of NSX-T. However, there is an essential need for a limited set of local users — to aid identity and access management in many scenarios. Scenarios such as (1) the ability to bootstrap and operate NSX during early stages of deployment before identity sources are configured in non-administrative mode or (2) when there is failure of communication/access to corporate identity repository. In such cases, local users are effective in bringing NSX-T to normal operational status. Additionally, in certain scenarios such as (3) being able to manage NSX in a specific compliant-state catering to industry or federal regulations, use of local guest users are beneficial. To enable these use-cases and ease-of-operations, two guest local-users have been introduced in 3.1.1, in addition to existing admin and audit local users. With this feature, the NSX admin has extended privileges to manage the lifecycle of the users (e.g., Password rotation, etc.) including the ability to customize and assign appropriate RBAC permissions. Please note that the local user capability is available on both NSX-T Local Managers (LM) and Global Managers (GM) but is unavailable on edge nodes in 3.1.1 via API and UI. The guest users are disabled by default and have to be explicitly activated for consumption and can be disabled at any time.
  • FIPS Compliant Bouncy Castle Upgrade: NSX-T 3.1.1 contains an updated version of FIPS compliant Bouncy Castle (v1.0.2.1). Bouncy Castle module is a collection of Java based cryptographic libraries, functions, and APIs. Bouncy Castle module is used extensively on NSX-T Manager. The upgraded version resolves critical security bugs and facilitates compliant and secure operations of NSX-T.

NSX Cloud

  • NSX Marketplace Appliance in Azure: Starting with NSX-T 3.1.1, you have the option to deploy the NSX management plane and control plane fully in Public Cloud (Azure only, for NSX-T 3.1.1. AWS will be supported in a future release). The NSX management/control plane components and NSX Cloud Public Cloud Gateway (PCG) are packaged as VHDs and made available in the Azure Marketplace. For a greenfield deployment in the public cloud, you also have the option to use a ‘one-click’ terraform script to perform the complete installation of NSX in Azure.
  • NSX Cloud Service Manager HA: In the event that you deploy NSX management/control plane in the public cloud, NSX Cloud Service Manager (CSM) also has HA. PCG is already deployed in Active-Standby mode thereby enabling HA.
  • NSX-Cloud for Horizon Cloud VDI enhancements: Starting with NSX-T 3.1.1, when using NSX Cloud to protect Horizon VDIs in Azure, you can install the NSX agent as part of the Horizon Agent installation in the VDIs. This feature also addresses one of the challenges with having multiple components ( VDIs, PCG, etc.) and their respective OS versions. Any version of the PCG can work with any version of the agent on the VM. In the event that there is an incompatibility, the incompatibility is displayed in the NSX Cloud Service Manager (CSM), leveraging the existing framework.

Operations

  • UI-based Upgrade Readiness Tool for migration from NVDS to VDS with NSX-T Data Center
    • To migrate Transport Nodes from NVDS to VDS with NSX-T, you can use the Upgrade Readiness Tool present in the Getting Started wizard in the NSX Manager user interface. Use the tool to get recommended VDS with NSX configurations, create or edit the recommended VDS with NSX, and then automatically migrate the switch from NVDS to VDS with NSX while upgrading the ESX hosts to vSphere Hypervisor (ESXi) 7.0 U2.

Licensing

  • Enable VDS in all vSphere Editions for NSX-T Data Center Users: Starting with NSX-T 3.1.1, you can utilize VDS in all versions of vSphere. You are entitled to use an equivalent number of CPU licenses to use VDS. This feature ensures that you can instantiate VDS.

Container Networking and Security

  • This release supports a maximum scale of 50 Clusters (ESXi clusters) per vCenter enabled with vLCM, on clusters enabled for vSphere with Tanzu as documented at configmax.vmware.com

Compatibility and System Requirements

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

API Deprecations and Behavior Changes

Retention Period of Unassigned Tags: In NSX-T 3.0.x, NSX Tags with 0 Virtual Machines assigned are automatically deleted by the system after five days. In NSX-T 3.1.0, the system task has been modified to run on a daily basis, cleaning up unassigned tags that are older than one day. There is no manual way to force delete unassigned tags.

Duplicate certificate extensions not allowed: Starting with NSX-T 3.1.1, NSX-T will reject x509 certificates with duplicate extensions (or fields) following RFC guidelines and industry best practices for secure certificate management. Please note this will not impact certificates that are already in use prior to upgrading to 3.1.1. Otherwise, checks will be enforced when NSX administrators attempt to replace existing certificates or install new certificates after NSX-T 3.1.1 has been deployed.
