Cisco Nexus Dashboard and Services

Cisco Nexus Dashboard is a central management console for multiple data center fabrics and a common platform for hosting Cisco data center operation services. These services are available for all the data center fabrics and provide real-time analytics, visibility, assurance for network policies and operations, as well as policy orchestration for the data center fabrics, such as Cisco Application Centric Infrastructure (ACI) or Cisco Nexus Dashboard Fabric Controller (NDFC). The services are as follows:

●      Cisco Nexus Dashboard Fabric Controller (NDFC): A comprehensive management solution for all Cisco NX-OS deployments spanning LAN, SAN, and IP Fabric for Media (IPFM) networks in data centers powered by Cisco. Cisco NDFC also supports devices such as IOS XE switches, IOS XR routers, and third-party devices. Being a multi-fabric controller, Cisco NDFC manages multiple deployment models such as VXLAN EVPN, classic 3-tier, FabricPath, and routed fabrics for LAN while providing ready-to-use control, management, monitoring, and automation capabilities. In addition, when enabled as a SAN controller, NDFC automates Cisco Multilayer Director Switches (MDS) and Cisco Nexus-family infrastructure in NX-OS mode with a focus on storage-specific features and analytics.

●      Cisco Nexus Dashboard Insights: Simplifies and automates visibility, troubleshooting, root-cause analysis, and remediation of network issues. By ingesting real-time streamed network telemetries from all devices, Nexus Dashboard Insights provides pervasive infrastructure visibility. It continuously verifies and validates the operational states of the network while proactively detecting any drifts from the operators’ intent, detecting different types of anomalies throughout the network, analyzing the root cause of anomalies, and identifying remediation methods. It modernizes the operation of networks, helping the network team to reduce troubleshooting efforts, increase operation efficiency, and proactively prevent network outages.

●      Cisco Nexus Dashboard Orchestrator: The intersite policy manager, which provides single-pane management that enables you to monitor the health of all interconnected fabrics. It also allows you to define centrally the intersite configurations and policies that can then be pushed to the different Cisco Application Policy Infrastructure Controller (APIC), Cisco Cloud Network Controller, or DCNM fabrics, which in turn 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 the Cisco Nexus Dashboard and supported services.

●      Beginning with NDFC release 12.2.2, when enabling the AI/ML feature, priority-flow-control watchdog-interval on is enabled on all your configured devices, intra-fabric links, and all your host interfaces where Priority Flow Control (PFC) is also enabled. This release also adds the Priority flow control watch-dog interval field. Here you can set the Priority flow control watch-dog interval field to a non-system default value (default is 100 milliseconds). Valid values are <101-1000>. For more information, see the section “About AI/ML QoS Classification and Queuing Policies” in Data Center VXLAN EVPN.

●      When you enable Tenant Routing Multicast (TRM) in a fabric and a VRF without VLAN mode is allowed in the fabric settings, vPC switches have the following auto-generated configuration:

router bgp <bgp asn>

mvpn vri id <vrf-id>

After upgrading to NDFC 12.2.2 and higher, when performing a Recalculate Config on the VXLAN fabric with TRM enabled, you can see an extra mvpn vri id configuration on the vPC switches.

●      During a VxLAN fabric brownfield import, set the vrf 'tag' field to a default of "12345" and no VRF loopbacks are detected.

●      Devices with the ToR role are not supported in a fabric with the artificial intelligence and machine learning (AI/ML) feature enabled. ToR devices do not use the AI/ML settings but are allowed to be added as a member of a fabric.

●      Openstack Visualizer is removed and is not available for you to start from the Admin > System Settings > Feature Management page of NDFC.

●      The multi-select option for selecting multiple nodes in a topology is now disabled for all fabrics and the Multi-Site Domain (MSD) view, including when you are in a VRF or in a network of an MSD.

●      A new template, ERSPAN, is added for Cisco Nexus 9000 series switches that support configuration of Encapsulated Remote Switched Port Analyzer (ERSPAN) source and destination ports.

●      In an eBGP fabric, if AS mode is Same-Tier-AS, you no longer need to create a leaf_bgp_asn policy. You can set the ASN in the fabric setting instead.

●      Precision Time Protocol (PTP) configuration change for links between leaf/spine and ToR/leafs. Intra-fabric links have additional configurations for the following switches, release versions, and neighbors:

◦    ptp - existing

◦    pttp delay-request minimum interval aes67 -3 – new

◦    ptp sync interval aes67 -3 - new

◦    Cisco Nexus N9K-C9408 – Cisco NX-OS release 10.4.(3)

◦    Cisco Nexus N9K-C93400LD-H1 – Cisco NX-OS release 10.4.(3)

◦    Cisco Nexus N9K-C9332D-H2R – Cisco NX-OS release 10.4.(2)

◦    Cisco Nexus N9K-C9364C-H1 – Cisco NX-OS release 10.5.(1)

●      Prior to NDFC release 12.2.2, fabric backup was supported for fabrics in monitored mode. Beginning with NDFC release 12.2.2, fabric backup is not supported for fabrics in monitored mode.

Changes in behavior for Insights

●      The Sites functionality is renamed "Fabrics" in the GUI.

●      For NDFC and standalone Nexus fabrics, when you upgrade from the Nexus Dashboard Insights 6.5.1 release to a later release, the telemetry configurations are retained throughout the upgrade. In previous releases, Nexus Dashboard Insights removes the configurations during the upgrade, then re-adds the configurations at the end of the upgrade. The more switches that you have in your fabric, the longer the process takes to re-adds the configurations. This could result in a long wait for the upgrade to complete. The new behavior results in a hitless upgrade for telemetry and the upgrade process is much faster than in previous releases.

These limitations apply to this new behavior:

◦    This new behavior applies only when you upgrade from the Nexus Dashboard Insights 6.5.1 release to a later release. When you upgrade to the 6.5.1 release from a previous release, the old behavior applies.

◦    Any new telemetry configurations that are included in the upgrade target release are not applied automatically. However, the GUI informs you of the new configurations. After the upgrade, you can then explicitly deploy the new configurations to the switches.

◦    This new behavior applies only to Nexus Dashboard Insights for Cisco NDFC or Standalone NX-OS.

◦    This new behavior does not apply if any switch in the fabric has Cisco NX-OS a release earlier than 9.3(5).

●      For NDFC and standalone Nexus fabrics, in previous releases, a clean wipe removes the Nexus Dashboard Insights configurations from the switches, disables the service, cleans up the Nexus Dashboard Insights data, and re-enables the service. The workflow for disabling then re-enabling Nexus Dashboard Insights also removes the Nexus Dashboard Insights configurations from the switches. Beginning with this release, a clean wipe as well as disabling then re-enabling Nexus Dashboard Insights retains the Nexus Dashboard Insights configurations on the switches.

Because of this new behavior, if you disabled Nexus Dashboard Insights and do not want to onboard the fabric back into Nexus Dashboard Insights, you must manually remove the Nexus Dashboard Insights configurations from the switches.

If you disabled Nexus Dashboard Insights and want to onboard the fabrics back into Nexus Dashboard Insights, use the unified backup and restore functionality. For more information about backup and restore, see the Unified Backup and Restore for Nexus Dashboard and Services document.

CSCvw47022

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

CSCvt47568

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.

CSCwa31774

When creating VRFs in infra tenant on a Google Cloud fabric, 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.
