What's in the Release Notes

The release notes cover the following topics:

What's New

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.

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

  • 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. 


  • 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.


  • 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.

Resolved Issues

  • Fixed Issue 2641824: On UI BFD profile realization status is shown as "uninitialized."

    There is no impact. This realization status can be ignored.

  • Fixed Issue 2643313: The realization state for a successfully realized Global T0 on an onboarded site incorrectly shows the "logical router port configuration realization error" for site edge transport nodes.

    You may notice realization failure with the error in realization of a T0 logical router port. If using policy API, this is transient and will resolve when T0-T1 plumbing completes.

  • Fixed Issue 2643632: No error is displayed while adding Global service as nested service on Local Manager.

    Policy intent creation is successful but realization fails. Local Service will not be realized on Management Plane, so it cannot be consumed in distributed firewall rules.

  • Fixed Issue 2646814: Overall consolidated status shows IN_PROGRESS whereas individual consolidated status per enforcement point shows SUCCESS.

    The consolidated status shows IN_PROGRESS but it does not give information on which site the status is IN_PROGRESS.

  • Fixed Issue 2648349: Repeated ObjectNotFoundException log and exception backtrace when Management Plane is collecting observation for traceflow or trace action result for livetrace.

    You will see repeated ObjectNotFoundException log in nsxapi.log when you create an LTA/Traceflow session.

  • Fixed Issue 2650292: In Federation, if a child group is used in two different groups and the second parent group has a higher span, the child group span will be greater than the span of the first group due to reference object creation. The span of the first group can be expanded but not reverted back to the original span.

    You will not be able to reduce the span of a domain on Global Manager.

  • Fixed Issue 2654842: A segment port can be created before the Windows physical server transport node creation is successful, causing the segment port to go to fail state.

    There is no visible UI indication that you need to wait until the transport node state is Success before proceeding with the Segment Port creation for Windows physical servers. If you try to create the Segment Port before the transport node is successful, it will fail.

  • Fixed Issue 2658484: NVDS to CVDS Migration via vSphere Update Manager is not fully supported via vSphere Update Manager "parallel mode."

    NVDS to CVDS migration issues may occur if migration is triggered by upgrading ESX via vSphere Update Manager in Parallel Mode. Switch will not be automatically migrated from NVDS to CVDS. System might be left in some inconsistent state.

  • Fixed Issue 2649228: IPv6 duplicate IP detection (DAD) state machine introduces 3 second delay on T0/T1 SR back plane port (and for T1 SR uplink port), when the IP is moved from one SR to another during failover. 

    N-S connectivity has up to 6 second v6 traffic loss during failover with T0 A/A.

  • Fixed Issue 2661502: Unable to make a Global Manager as standby from the UI after an unplanned switchover where this Global Manager was lost but is back online after the switchover.

    If a previously active Global Manager is back online after you have switched to the standby Global Manager which is the new active Global Manager, the old active Global Manager has the status of NONE. When you try to set this as the standby Global Manager from the UI, the operation fails.

  • Fixed Issue 2623704: If you use the Management Plane API to configure L3 forwarding mode, Policy will overwrite Management Plane change with default mode IPV4_ONLY and will disrupt IPv6 connectivity.

    L3 forwarding mode configuration was introduced in Policy in the NSX-T 3.0.0 release. This issue impacts NSX-T 3.0.1 and 3.0.2 upgrades to NSX-T 3.1.0. Upgrades from NSX-T 2.5.x to NSX-T 3.1.0 and NSX-T 3.0.0 to NSX-T 3.1.0 are not affected. IPv6 forwarding is disabled in the data path, resulting in IPv6 connectivity loss.

  • Fixed Issue 2674146: When upgrading to NSX-T 3.1.0, in the host upgrade section, a "Stage" button is present and active for all clusters/host groups. The option is applicable to vSphere Lifecycle Management (vLCM) enabled clusters only, which is not applicable in this scenario because NSX-T support with vLCM is enabled from the NSX-T 3.1.0 and vSphere 7.0 U1 version combination.

    The "Stage" button is active for all clusters although vSphere Lifecycle Management is not enabled on any of the clusters. If you click the "Stage" option, a confirmation message appears, which if you then click "Yes", the cluster shows as if it's been staged for upgrade. If you then click "Start" to begin upgrades, the cluster undergoes the same upgrades as it would have if initiated through regular NSX host upgrades.

  • Fixed Issue 2659168: Async replicator channel sometimes remains down during node restart.

    Sync status is down. Changes on Global Manager won't go to Local Manager.

  • Fixed Issue 2655295: Post Upgrade, repository sync status is marked as FAILED on the NSX Manager UI.

    Repository sync status is shown as failed on the NSX Manager UI. However, you can perform all installation- and upgrade-related operations.

  • Fixed Issue 2658950: Upgrade workflow of Local Manager interrupted if Local Manager was added to the Global Manager using its VIP but later FQDN of the Local Manager was published.

    If a Local Manager was added to the Global Manager using its VIP and later you have published the Local Manager's FQDN, the Global Manager fails to access the Local Manager to proceed with the upgrade.

  • Fixed Issue 2609681: DFW jumpto rule action is not supported on rules having Layer 7 APPID or FQDN Context profiles.

    The Traffic will not match the intended rule after vMotion. Rule match will not be correct, allowing the traffic to pass through if it was supposed to be blocked.

  • Fixed Issue 2657943: Upgrade of edge deployed on bare metal server having more than one disk might fail.

    When the system is rebooting midway through the update, the bootup fails with errors related to mounting the filesystems. The edge upgrade will fail.

  • Fixed Issue 2653227: When removing the Physical Server from NSX, connectivity is lost to Physical Server and NSX uninstall fails.

    The attached interface of segment port on Physical Server is configured as "Using existing IP."  When removing the Physical Server from NSX without removing segment port first, connectivity is lost to Physical Server and NSX uninstall fails.

  • Fixed Issue 2658199:  When adding Windows Bare Metal Server 2016/2019, a "host disconnected" error displays at the Applying NSX Switch Configuration step.

    Regardless of the error message -- which may or may not be an issue -- the installation appears to continue and eventually finish properly.

  • Fixed Issue 2658713: When workload connected to T0 segment sends an IGMP leave for group G, the entry is not removed from the IGMP snooping table on T0 SR.

    When workload connected to T0 segment sends an IGMP leave for group G, the entry is not removed from the IGMP snooping table on T0 SR.

  • Fixed Issue 2652154: The Global Manager can experience slowness in processing deletes during scenarios where high numbers of resources are being deleted across sites.

    Error messages are seen that a particular resource cannot be created or deleted because it will affect the span of many resources that are pending cleanup on a site. These error messages indicate that the Global Manager is still processing acknowledgements of cleanup from all of the sites for many resources.

  • Fixed Issue 2659234: Live Traffic Analysis (LTA) sessions are not freed when you trigger an LTA request in parallel.

    When there is an uncleared LTA session.

    1. Host will continuously report LTA result to Management Plane (MP), so MP always receives the leak LTA session and print log in nsxapi.log.
    2. Packets sent from a host that has an uncleared LTA session will be padded LTA INT Geneve header.
  • Fixed Issue 2622846: IDS with proxy settings enabled cannot access GitHub, which is used to download signatures.

    New updates of signature bundle downloads will fail.

  • Fixed Issue 2656929: If Windows 2016/2019 Physical Server is not completed, segment port fails when attempting to create segment port.

    Segment port will show a failure.

  • Fixed Issue 2645877: In Bare Metal Edge, traffic going through a VRF gateway may not reach its destination.

    Packet capture on the link partner shows that the packets are received with no checksum, but a fragmentation offset in the IP header. Traffic crossing the VRF gateway is dropped because the packets are corrupted.

  • Fixed Issue 2637241: Global Manager to Local Manager communication broken (workflows relying on password/thumbprint) after Local Manager cert replacement.

    Absence of status updates and some functionality for Global Manager to Local Manager communication.

  • Fixed Issue 2522909: Service VM upgrade is not working after correcting URL if upgrade deployment failed with Invalid url.

    Upgrade would be in failed state, with wrong URL, blocking upgrade.

  • Fixed Issue 2527671: When the DHCP server is not configured, retrieving DHCP statistics/status on a Tier0/Tier1 gateway or segment displays an error message indicating realization is not successful.

    There is no functional impact. The error message is incorrect and should report that the DHCP server is not configured.

  • Fixed Issue 2549175: Searching in policy fails with the message: "Unable to resolve with start search resync policy."

    Searching in policy fails because search is out of sync when the NSX Manager nodes are provided with new IPs.

  • Fixed Issue 2588072: NVDS to CVDS switch migrator doesn't support Stateless ESX with vmks.

    NVDS to CVDS switch migrator cannot be used for migration with Stateless ESX hosts if the NVDS switch has vmks on it.

  • Fixed Issue 2627439: If a transport node profile is applied on a cluster before migration, one extra transport node profile is created by the system in detached state after migration.

    There will one extra transport node profile generated for each original transport node profile.

  • Fixed Issue 2628428: Global Manager status shows success initially and then changes to IN_PROGRESS.

    In a scale setup, if there are too many sections being modified at frequent intervals, it takes time for the Global Manager to reflect the correct status of the configuration. This causes a delay in seeing the right status on the UI/API for the distributed firewall configuration done.

  • Fixed Issue 2634034, 2656024: When the site role is changed for a stretched T1-LR (logical router), any traffic for that logical router is impacted for about 6-8 minutes.

    The static route takes long to get programmed and affects the datapath. There will be traffic loss of about 6-8 minutes when the site role is changed. This could be even longer based on the scale of the config.

  • Fixed Issue 2527344: If selecting the Type as "TIER0_EVPN_TEP_IP" in Route redistribution of Tier 0 VRF LR, the TIER0_EVPN_TEP_IP is not redistributed into BGP as it is present in Parent Tier 0 LR, causing the datapath to break.

    Doing so will not advertise the TIER0_EVPN_TEP_IP to DC gateway (Peer BGP Router). In Tier 0 VRF LR Route Redistribution, you can select the Type as "TIER0_EVPN_TEP_IP", but there are no routes of "TIER0_EVPN_TEP_IP" on Tier 0 VRF LR.

  • Fixed Issue 2547524: Firewall rules not applied for cross-site vMotion use-case where discovered segment ports are used in global groups.

    Rules are not pushed as expected.

  • Fixed Issue 2573975: While configuring ANY to ANY SNAT rule, the addresses specified for source-network/destination-network/translated-network properties as empty string ("") will result in realization failure on management plane.

    The rule will not get realized on the edge and management plane.

  • Fixed Issue 2668561: When a load balancer virtual server is configured with a single port range like 1000-2000, it may lead to a datapath process crash on the Edge Nodes where that load balancer is realized, leading to traffic disruption.

    Traffic going through the Edge may be disrupted and BGP peering with that Edge Node may go down.

Known Issues

The known issues are grouped as follows.

General Known Issues
  • Issue 2329273: No connectivity between VLANs bridged to the same segment by the same edge node.

    Bridging a segment twice on the same edge node is not supported. However, it is possible to bridge two VLANs to the same segment on two different edge nodes.

    Workaround: None 

  • Issue 2355113: Unable to install NSX Tools on RedHat and CentOS Workload VMs with accelerated networking enabled in Microsoft Azure.

    In Microsoft Azure when accelerated networking is enabled on RedHat (7.4 or later) or CentOS (7.4 or later) based OS and with NSX Agent installed, the ethernet interface does not obtain an IP address.

    Workaround: After booting up RedHat or CentOS based VM in Microsoft Azure, install the latest Linux Integration Services driver available at https://www.microsoft.com/en-us/download/details.aspx?id=55106 before installing NSX tools.

  • Issue 2520803: Encoding format for Manual Route Distinguisher and Route Target configuration in EVPN deployments.

    You currently can configure manual route distinguisher in both Type-0 encoding and in Type-1 encoding. However, using the Type-1 encoding scheme for configuring Manual Route Distinguisher in EVPN deployments is highly recommended. Also, only Type-0 encoding for Manual Route Target configuration is allowed.

    Workaround: Configure only Type-1 encoding for Route Distinguisher.

  • 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 2537989: Clearing VIP (Virtual IP) does not clear vIDM integration on all nodes.

    If VMware Identity Manager is configured on a cluster with a Virtual IP, disabling the Virtual IP does not result in the VMware Identity Manager integration being cleared throughout the cluster. You will have to manually fix vIDM integration on each individual node if the VIP is disabled.

    Workaround: Go to each node individually to manually fix the vIDM configuration on each.

  • 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 2523212: The nsx-policy-manager becomes unresponsive and restarts.

    API calls to nsx-policy-manager will start failing, with service being unavailable. You will not be able to access policy manager until it restarts and is available.

    Workaround: Invoke API with at most 2000 objects.

  • Issue 2521071: For a Segment created in Global Manager, if it has a BridgeProfile configuration, then the Layer2 bridging configuration is not applied to individual NSX sites.

    The consolidated status of the Segment will remain at "ERROR". This is due to failure to create bridge endpoint at a given NSX site. You will not be able successfully configure a BridgeProfile on Segments created via Global Manager.

    Workaround: Create a Segment at the NSX site and configure it with bridge profile.

  • Issue 2532127: LDAP user can't log in to NSX only if the user's Active Directory entry does not contain the UPN (userPrincipalName) attribute and contains only the samAccountName attribute.

    User authentication fails and the user is unable to log in to the NSX user interface.

    Workaround: None.

  • 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 inaccurate count of IDFW/IDS enabled clusters. There is no functional impact. Only the count of the enabled clusters is wrong.

    Workaround: None.

  • 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: See VMware knowledge base article 78794.

  • Issue 2499819: Maintenance-based NSX for vSphere to NSX-T Data Center host migration for vCenter 6.5 or 6.7 might fail due to vMotion error.

    This error message is shown on the host migration page:
    Pre-migrate stage failed during host migration [Reason: [Vmotion] Can not proceed with migration: Max attempt done to vmotion vm b'3-vm_Client_VM_Ubuntu_1404-shared-1410'].

    Workaround: Retry host migration.

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

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

    Workaround: Take a backup after any updates to TNP.

  • Issue 2392064: Edge stage migration fails with, "Failed to fetch error list" error.

    Migration fails but the reason for the failure (DHCP plugin exception) is not shown.

    Workaround: Roll back migration and retry.

  • Issue 2468774: When option 'Detect NSX configuration change' is enabled, backups are taken even when there is no configuration change.

    Too many backups are being taken because backups are being taken even when there are no configuration changes.

    Workaround: Increase the time associated with this option, thereby reducing the rate at which backups are taken.

  • Issue 2523421: LDAP authentication does not work properly when configured with an external load balancer (configured with round-robin connection persistence).

    The API LDAP authentication won't work reliably and will only work if the load balancer forwards the API request to a particular Manager.

    Workaround: None.

  • Issue 2534921: Not specifying inter_sr_ibgp property in a PATCH API call will prevent other fields from being updated in the BgpRoutingConfig entity.

    PATCH API call fails to update BGP routing config entity. Error_message "BGP inter SR routing requires global BGP and ECMP flags enabled." BgoRoutingConfig will not be updated.

    Workaround: Specify inter_sr_ibgp property in the PATCH API call to allow other fields to be changed.

  • Issue 2566121: A UA node stopped accepting any New API calls with the message, "Some appliance components are not functioning properly."

    The UA node stops accepting any New API calls with the message, "Some appliance components are not functioning properly." There are around 200 connections stuck in CLOSE_WAIT state. These connections are not yet closed. New API call is rejected.

    Workaround: Restart proton service (service proton restart) or restart unified appliance node.

  • 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 2596162: Unable to update the nsxaHealthStatus for a switch when the switch name contains a single quote.

     NSX configuration state is at partial success because the health status of a switch could not be updated. 

    Workaround: Change the host switch name so that is does not have any single quotes.

NSX Edge Known Issues
  • Issue 2283559: https://<nsx-manager>/api/v1/routing-table and https://<nsx-manager>/api/v1/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 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.

    Workaround: Rely on the output of ‘get bfd-sessions’ and check the ‘State’ field to get the most up-to-date BFD status.

  • Issue 2641990: During Edge vMotion, there can be multicast traffic loss up to 30 seconds (default pim hello interval).

    When edge is vMotioned and IGMP snooping is enabled on TOR, The TOR needs to know the new edge location. This can be learned by TOR when it gets any of the multicast control or data traffic from the edge. Multicast Traffic is lost up to 30 seconds on edge vMotion.

    Workaround: None. Traffic will recover upon TOR receiving multicast packets, or for faster recovery, disable/enable pim on the uplink interface connected to TOR.

Security Known Issues
  • 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.

  • 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.

    Workaround: Keep the pNic MTU and intermediate routers' MTU bigger than the global MTU (i.e., the MTU used by inter-SR port). The size of the packets becomes more than MTU because of encapsulation and packets don't go through.

  • 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". 

    Workaround: Wait for fabric sync between Global Manager and Local Manager to complete.
