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.

This release allows you to enable the following new use cases for policy-based redirect (PBR) with Multi-Site:
● vzAny and PBR for any-to-any communication
● vzAny and PBR for many-to-one communication
● Inter-site transit routing (L3Out-to-L3Out) with PBR
|
|

The following additional template object properties can now be configured directly from Nexus Dashboard Orchestrator for ACI fabrics:
● Annotations for template objects
● EPG admin state
● VMM Domain customized delimiter, port bindings, NetFlow, MAC address changes, forged transmits, promiscuous mode,
● Intra EPG contracts
● Bridge Domain (BD) endpoint (EP) move detection mode
● VRF BD enforcement status
● External EPG QoS class and subnet name
|
|
| Additional NDO-NDFC integration enhancements |

● RS Route tags
|
|
| Ease of Use |
UI look-and-feel improvements |
This release adds product GUI improvements, including a new operations overview page and journey map. |
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, we recommend deploying Nexus Dashboard Orchestrator service in Nexus Dashboard 3.0(1) or later.
● 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.
● 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.
● 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.
● 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.

4.2(1d) |
|
|
|
||
| In some cases, route redirect is not enabled on service nodes of a graph. |
4.2(1e) |
|
This section lists known behaviors. Click the Bug ID to access the Bug Search Tool and see additional information about the issue.
| 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 |
|
| 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. |
|
| 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. |
