This document describes the features, issues, and deployment guidelines for Cisco Nexus Dashboard Orchestrator software.
Cisco Multi-Site is an architecture that allows you to interconnect separate Cisco APIC, Cloud Network Controller (formerly known as Cloud APIC), and 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.

Release 4.0(2i) became available. |
This release adds the following new features:
| Feature |
Description |
| Hybrid Cloud support for NDFC-managed VXLAN EVPN fabrics (AWS and Azure) |
This release adds hybrid cloud support for on-premises NX-OS-based fabrics managed by NDFC to AWS and Azure clouds managed by Cisco Cloud Network Controller. For more information, see the “Integration with Cloud Network Controller” chapter in the Nexus Dashboard Orchestrator Configuration Guide for NDFC Fabrics. |
| Hybrid Cloud support for integrating ACI fabrics with Google Cloud via VXLAN EVPN |
You can now configure BGP-EVPN connection for inter-site connectivity between a Google Cloud site and other cloud sites or an ACI on-premises site. For more information, see Managing Google Cloud Sites Using Nexus Dashboard Orchestrator. |
| SR-MPLS Intersite L3Out support for ACI fabrics |
The following SR-MPLS use cases are supported in this release:
● Multiple sites each with their own local SR-MPLS L3Outs and traffic using the local L3Out if it is available or a remote SR-MPLS L3Out from another site (intersite L3Out).
◦ In this case, the remote SR-MPLS L3Out can be used as a simple backup or in case of unique prefixes for each SR-MPLS L3Out. Traffic will transit from a local EPG to the local SR-MPLS L3Out and if that path is down or the route is unavailable it can take another site's remote SR-MPLS L3Out.
● Similar use cases are supported for shared services, where application EPG in one VRF can use SR-MPLS L3Out in a different VRF, either in the local or remote site.
◦ In this case, the EPGs can be in a different tenant as well. For example, Tenant1 in Site1 can contain the application EPGs which will use an SR-MPLS L3Out in Tenant2 in Site2.
For more information, see the “Multi-Site and SR-MPLS L3Out Handoff” chapter in the Nexus Dashboard Orchestrator Configuration Guide for ACI Fabrics. |
| Support for both virtual and cloud availability zones for AWS sites |
When configuring regions for VRFs in AWS cloud sites and providing CIDR subnet information, you can now choose either virtual availability zones or cloud availability zones for the subnets. Additional information about virtual and cloud availability zones is available in Cisco Cloud Network Controller for AWS User Guide. |
There is no new hardware supported in this release.
The complete list of supported hardware is available in the “Deploying Nexus Dashboard Orchestrator” chapter of the Cisco Multi-Site Deployment Guide.
● For all new deployments, you must install Nexus Dashboard Orchestrator service in Nexus Dashboard 2.1(2d) or later.
● If you are upgrading from a release prior to release 4.0(1), you must back up your configuration, remove the existing Orchestrator instance, deploy this release, and then restore the configuration backup from your existing cluster.
Ensure that you follow the complete upgrade prerequisites, guidelines, and procedure are described in detail in the “Upgrading Nexus Dashboard Orchestrator” chapter of the Cisco Nexus Dashboard Orchestrator Deployment Guide.
● Downgrading from this release is not supported.
We recommend creating a full backup of the configuration before upgrading to Release 4.0(x), 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.
● 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.
● When deploying a subset of template policies, such as after a configuration change or update, the deployment time has been significantly improved.
● Beginning with Cisco Cloud APIC release 25.0(5), Cisco Cloud APIC is renamed as Cisco Cloud Network Controller.
Nexus Dashboard Orchestrator can manage Cloud Network Controller sites the same way it managed Cloud APIC sites previously. For the full list of service and fabric compatibility options, see the Nexus Dashboard and Services Compatibility Matrix.

| Bug ID |
Description |
| 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 |
|
| Unicast traffic flow between Remote Leaf Site1 and Remote Leaf in Site2 may be enabled by default. This feature is not officially supported in this release. |
|
| After downgrading from 2.1(1), preferred group traffic continues to work. You must disable the preferred group feature before downgrading to an earlier release. |
|
| No validation is available for shared services scenarios |
|
| The upstream server may time out when enabling audit log streaming |
|
| For Cisco Multi-Site, Fabric IDs Must be the Same for All Sites, or the Querier IP address Must be Higher on One Site. The Cisco APIC fabric querier functions have a distributed architecture, where each leaf switch acts as a querier, and packets are flooded. A copy is also replicated to the fabric port. There is an Access Control List (ACL) configured on each TOR to drop this query packet coming from the fabric port. If the source MAC address is the fabric MAC address, unique per fabric, then the MAC address is derived from the fabric-id. The fabric ID is configured by users during initial bring up of a pod site. In the Cisco Multi-Site Stretched BD with Layer 2 Broadcast Extension use case, the query packets from each TOR get to the other sites and should be dropped. If the fabric-id is configured differently on the sites, it is not possible to drop them. To avoid this, configure the fabric IDs the same on each site, or the querier IP address on one of the sites should be higher than on the other sites. |
|
| STP and "Flood in Encapsulation" Option are not Supported with Cisco Multi-Site. In Cisco Multi-Site topologies, regardless of whether EPGs are stretched between sites or localized, STP packets do not reach remote sites. Similarly, the "Flood in Encapsulation" option is not supported across sites. In both cases, packets are encapsulated using an FD VNID (fab-encap) of the access VLAN on the ingress TOR. It is a known issue that there is no capability to translate these IDs on the remote sites. |
|
| 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 an 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. |
|
| Missing BD1/VRF1 in site S2 will impact the forwarding from EPG1 in site S1 to EPG1/EPG2 in site S2 |
|
| When using APIs, template names must not include spaces. |
|
| After unmanaging an external fabric that contains route-servers, Infra Connectivity page in NDO still shows the route-servers. Since the route-servers are still maintained, the overlay IFC from the route-servers to any BGW devices in the DCNM are not removed. |
