New Software Features. 3



Cisco Multi-Site is an architecture that allows you to interconnect separate Cisco APIC, Cloud Network Controller (formerly known as Cloud APIC), and Cisco NDFC (formerly known as DCNM) domains (fabrics) each representing a different region. This helps ensure multitenant Layer 2 and Layer 3 network connectivity across sites and extends the policy domain end-to-end across the entire system.

Cisco Nexus Dashboard Orchestrator is the intersite policy manager. It provides single-pane management that enables you to monitor the health of all the interconnected sites. It also allows you to centrally define the intersite configurations and policies that can then be pushed to the different Cisco APIC, Cloud Network Controller, or DCNM fabrics, which in term deploy them in those fabrics. This provides a high degree of control over when and where to deploy the configurations.

This document describes the features, issues, and limitations for this release of Nexus Dashboard Orchestrator. For more information, see the “Related Content” section at the end of this document.

New Software Features

This release adds the following new features:

Product Impact



Base Functionality

'Common' Tenant Support for Hybrid Cloud Environments

You can now stretch the 'common' tenant between an on-premises ACI and a Cloud Network Controller sites.

Monitoring template "L3Out source filter" capability

You can now filter the source packets based on the EPG or L3Out from which they are coming.

EPG to physical domain association and path binding selection

You can now associate EPGs with physical domains and path bindings defined in the fabric policy and fabric resource templates.

Description field for Interface Policy Group (IPG)

You can now provide a description for the Interface Policy Group (IPG) objects.


vSphere 8.0 Support

Nexus Dashboard clusters can now be deployed in VMware vSphere 8.0.


Prevent template editor from self-approval

Template editors can no longer approve their own changes.

Ease of Use

UI Navigation Improvements

This release adds product GUI improvements, including main navigation bar changes for consistency across the platform and services.


PATCH API Support for L3Out Templates

You can now use the PATCH APIs with L3Out templates.


New Hardware Features

There is no new hardware supported in this release.

Changes in Behavior

     Beginning with Nexus Dashboard release 3.1(1), all services have been unified into a single deployment image.

You no longer need to download, install, and enable each service individually. Instead, you can simply choose which services to enable during the Nexus Dashboard platform deployment process. As a result, we recommend deploying Nexus Dashboard release 3.1(1) with unified install for all new installations.

Upgrading to this release will also automatically upgrade all services in your existing cluster.

     If you upgrade to this release from a release prior to 4.0(1) and have template versioning enabled, only the latest versions of the templates are preserved during the upgrade.

All other existing versions of templates, including older versions that are tagged Golden, will not be transferred during the upgrade.

     If you upgrade to this release from a release prior to 4.0(1), existing schemas’ IDs may change.

If you are using any API automation that relies on static Schema IDs, we recommend dynamically obtaining the IDs before executing any action against the Schemas.

     Beginning with Nexus Dashboard release 3.1(1) and Orchestrator release 4.3(1), patch API is supported for L3Out templates.

See the Nexus Dashboard Orchestrator API documentation for the full API changelog.

     Beginning with Release 4.0(1), the “Application Profiles per Schema” scale limit has been removed.

For the full list of maximum verified scale limits, see the Nexus Dashboard Orchestrator Verified Scalability Guide.

     Beginning with Release 4.0(1), if you have route leaking configured for a VRF, you must delete those configurations before you delete the VRF or undeploy the template containing that VRF.

     Beginning with Release 4.0(1), if you are configuring EPG Preferred Group (PG), you must explicitly enable PG on the VRF.

In prior releases, enabling PG on an EPG automatically enabled the configuration on the associated VRF. For detailed information on configuring PG in Nexus Dashboard Orchestrator, see the “EPG Preferred Group” chapter of the Cisco Nexus Dashboard Orchestrator Configuration Guide for ACI Fabrics.

     Note that CloudSec encryption for intersite traffic will be deprecated in a future release.

We recommend not enabling (if currently disabled) or disabling (if currently enabled) this feature for your ACI Multi-Site deployments.

     Downgrading from this release is not supported.

We recommend creating a full backup of the configuration before upgrading, so that if you ever want to downgrade, you can deploy a brand-new cluster using an earlier version and then restore your configuration in it.

Bug ID                    


Exists in          


When service graphs or devices are created on Cloud APIC by using the API and custom names are specified for AbsTermNodeProv and AbsTermNodeCons, a brownfield import to the Nexus Dashboard Orchestrator will fail.

4.3(1) and later


Contract is not created between shadow EPG and on-premises EPG when shared service is configured between Tenants.

4.3(1) and later


Inter-site shared service between VRF instances across different tenants will not work, unless the tenant is stretched explicitly to the cloud site with the correct provider credentials. That is, there will be no implicit tenant stretch by Nexus Dashboard Orchestrator.

4.3(1) and later


Deployment window may not show all the cloud related config values that have been modified.

4.3(1) and later


After brownfield import, the BD subnets are present in site local and not in the common template config

4.3(1) and later


In shared services use case, if one VRF has preferred group enabled EPGs and another VRF has vzAny contracts, traffic drop is seen.

4.3(1) and later


The REST API call "/api/v1/execute/schema/5e43523f1100007b012b0fcd/template/Template_11?undeploy=all" can fail if the template being deployed has a large object count

4.3(1) and later


Shared service traffic drops from external EPG to EPG in case of EPG provider and L3Out vzAny consumer

4.3(1) and later


Two cloud sites (with Private IP for CSRs) with the same InfraVNETPool on both sites can be added to NDO without any infraVNETPool validation.

4.3(1) and later


Multiple Peering connections created for 2 set of cloud sites.

4.3(1) and later


Route leak configuration for invalid Subnet may get accepted when Internal VRF is the hosted VRF. There would be fault raised in cAPIC.

Username and password is not set properly in proxy configuration so a component in the container cannot connect properly to any site.

In addition, external module pyaci is not handling the web socket configuration properly when user and password are provided for proxy configuration.

4.3(1) and later


Implicit Filters and Contracts are not getting updated when the original policies are modified. Any small property changes in policies is not updating the implicit objects.

4.3(1) and later


For a BD in NDO schema, only the linked L3Out name is populated, and the BD's L3Out reference field is empty even though the L3Out is managed by NDO.

This behavior can be observed in the Reconcile Drift UI where the BD's L3Out reference is missing in the NDO schema tab, and only the name is displayed.

4.3(1) and later


If a stretched external EPG is associated to a shadow L3Out during an upgrade, drift reconciliation does not detect the L3Out or the external EPG.

4.3(1) and later


The issue occurs in the following scenario:

1. Deployed template version1

2. Modify the template to version2

3. Undeploy the template without first deploying version2.

The undeployment happens on version1 but the UI displays the data from version2.

4.3(1) and later


After migrating some object (such as a BD) from site local template to stretched template and then add a new object to that site local template, trying to deploy it may result in the following error:

Template deployment failed: this is a stretch object migration case. Please deploy the target template ZZZZ in schema XXXXX first.

4.3(1) and later

Resolved Issues

This section lists the resolved issues. Click the bug ID to access the Bug Search tool and see additional information about the issue. The "Fixed In" column of the table specifies whether the bug was resolved in the base release or a patch release.

Bug ID                    


Fixed in          


When configuring a site-specific subnet on a Non-Layer 2 stretched BD, only one subnet can be set to primary. An error occurs when attempting to deploy the template stating that only one preferred subnet per address family is allowed under the BD.



There is a false Config-Drift notification on the NDO about all Fabric Resource Policy objects.

Deploying the Fabric Resource Policy template will remove the Config-Drift notification. After two days, the Config-Drift notification reappears about the Fabric Resource Policy template even though nothing was changed on the APIC.


Known Issues

This section lists known behaviors. Click the Bug ID to access the Bug Search Tool and see additional information about the issue.

Bug ID                    



NDO will not update or delete VRF vzAny configuration which was directly created on APIC even though the VRF is managed by NDO.


Unable to download Nexus Dashboard Orchestrator report and debug logs when database and server logs are selected


For hybrid cloud deployments, no validation is available for shared services scenarios


If an infra L3Out that is being managed by Cisco Multi-Site is modified locally in a Cisco APIC, Cisco Multi-Site might delete the objects not managed by Cisco Multi-Site in the Infra L3Out.


"Phone Number" field is required in all releases prior to Release 2.2(1). Users with no phone number specified in Release 2.2(1) or later will not be able to log in to the GUI when Orchestrator is downgraded to an earlier release.


Routes are not programmed on CSR and the contract config is not pushed to the Cloud site.


Shadow of cloud VRF may be unexpectedly created or deleted on the on-premises site.


Let's say APIC has EPGs with some contract relationships. If this EPG and the relationships are imported into NDO and then the relationship was removed and deployed to APIC, NDO doesn't delete the contract relationship on the APIC.


When creating VRFs in infra tenant on a Google Cloud site, you may see them classified as internal VRF in NDO. If you then import these VRFs in NDO, the allowed routeleak configuration will be determined based on whether the VRF is used for external connectivity (external VRF) or not (internal VRF).

This is because on cAPIC, VRFs in infra tenant can fall into 3 categories: internal, external and un-decided.

NDO treats infra tenant VRFs as 2 categories for simplicity: internal and external.

There is no usecase impacted because of this.


Removing site connectivity or changing the protocol is not allowed between two sites.


Template goes to approved state when the number of approvals is fewer than the required number of approvers.


After a site is re-registered, NDO may have connectivity issues with APIC or CAPIC


If cloud sites have EVPN-based connectivity with another cloud or on-premises site, then contract-based routing must be enabled for intersite traffic to work.


When APIC-owned L3Outs are deleted manually on APIC by the user, stretched and shadow InstP belonging to the L3Outs get deleted as expected. However, when deploying the template from NDO, only the stretched InstPs detected in config drift will get deployed.


NSG rules on Cloud EPG are removed right after applying service graph between Cloud EPG and on-premises EPG, which breaks communication between Cloud and on-premises.


Existing IPSec tunnel state may be affected after update of connectivity configuration with external device.


User can not withdraw the hubnetwork from a region if intersite connectivity is deployed.


BGP sessions from Google Cloud site to AWS/Azure site may be down due to CSRs being configured with a wrong ASN number.


APIC has GOTO and GOTHROUGH options when configuring an L3 device, but in NDO the GOTHROGH option is not exposed intentionally. Only the GOTO option is supported.


May be unable to deploy a template with VPCI after modifying Node 1 and Node 2.

NDO will not delete a VPC peer group on APIC, because it may be shared by multiple other VPCs that are not managed by NDO, removing which may cause config issues.


After an upgrade to NDO 4.2.1 or later, the orchestrator raises configuration drifts that are not automatically reconciled, associated to the configuration objects for Service Devices and Service Graphs.
