| Date |
Description |
| November 5, 2021 |
Release 6.0.1 (6.0.1.41) patch became available. |
| September 14, 2021 |
Release 6.0.1 (6.0.1.23) became available. |
| Feature |
Description |
| Unified service |
Deploy a single tool with assurance, advisory, and troubleshooting capabilities to address your operational needs of prevention, diagnosis, and remediation. |
| One View |
The One View feature in Nexus Dashboard Insights offers the functionality of a single pane of glass or a central point of operation for Nexus Dashboard Insights services. After configuring the clusters in Cisco Nexus Dashboard, you can access and perform all operations on a Site Group or a site using the One View function. |
| Sites support |
Support for ACI and DCNM sites in the same Nexus Dashboard Insights instance. |
| Add Sites or Upload Files to Site Groups and Run Assurance Analysis |
Allows you to add and manage sites in Site Groups and run Assurance Analysis for a site and for uploaded files. |
| Explore |
Allows network operators to discover assets and their object associations in an easy-to-consume natural language query format. |
| Compliance |
Allows you to specify compliance requirements. Cisco Nexus Dashboard Insights will verify in the subsequent snapshots, whether the compliance requirements are satisfied by the policy that is configured in the fabric. |
| Pre-Change Analysis |
When you want to change a configuration for a site, this allows you to model the intended changes, perform a Pre-Change Analysis against an existing base snapshot in the site, and verify if the changes generate the desired results. In addition to multiple tenants, you can also add multiple infrastructure objects as part of a Pre-Change Analysis JSON or XML job. |
| Policy CAM workflow |
Determines how and where resources in the fabric are used. Policy CAM provides information about the resource utilization in the network, and the amount of policy content-addressable memory (Policy CAM) utilization. |
| Delta Analysis |
Enables you to analyze the difference in the policy, run time state, and the health of the network between two snapshots. |
| Import and Export of configurations |
Enables you import and export the configurations such as Site Groups, alert rules, compliance, flow rules, user preferences in Nexus Dashboard Insights. |
| Firmware Upgrade Analysis |
Suggests an upgrade path to a recommended software version and determines the potential impact of upgrade impact. It also helps with the pre-upgrade and post-upgrade validation checks. |
| Analyze Alerts |
Analyze Alerts provides a view into Anomalies and Advisories generated by Nexus Dashboard Insights. With this release you can configure the properties such as acknowledge an anomaly, assign a user, add a tag, add a comment, set verification status, on an anomaly. Using One-Click Remediation you can remediate an anomaly based on recommendations. |
| Alert Rules |
Enables you to acknowledge all new detected anomalies that match the criteria and adjust the anomaly score accordingly. |
| Netflow support |
Enables the network administrator to determine information such as source, destination, class of service, and causes of congestion. Netflow is configured on the interface to monitor every packet on the interface and provide telemetry data. |
| Flow Telemetry enhancements |
Allows users to see the path taken by different flows in detail. You can see the switches in the flow with the help of flow table exports from the nodes. All flows are monitored as a consolidated view in a unified pipeline for site types ACI and DCNM. |
| Kafka support enhancements |
Export data collected by Nexus Dashboard Insights over Kafka and Email. |
| Endpoints enhancements |
Endpoints displays time series information for the top nodes with number of endpoints that are varying. The Endpoints feature provides detailed analytics of endpoints learned in the site. With this release, support for searching deleted IP addresses is available. And filtering by hostname is also supported as a Beta feature. |
| Interface enhancements |
This feature includes monitoring of nodes and interfaces in Cisco Nexus Dashboard Insights and site nodes. With this release, Switch Virtual Interfaces are supported in addition to physical ports, port channels, and vPCs. For vPC interface, logical neighbors information is displayed. |
| Log Collector enhancements |
With this release, you can automatically upload the log files to Cisco Intersight Cloud after the log collection job is completed. |
| Virtual Nexus Dashboard support |
Allows you to deploy Nexus Dashboard Insights service on Virtual Nexus Dashboard (vND). |
| Beta feature – DNS Integration |
This is a Beta feature. We recommend that you use features marked as ‘Beta’ in your test environments but not in production deployments. The Cisco Nexus Dashboard Insights Domain Name System (DNS) integration feature enables the name resolution feature to telemetry data. DNS integration can be associated at the Site Group level or the Site level. |

Usage Guidelines and Limitations
This section lists the usage guidelines and limitations for Cisco Nexus Dashboard Insights:
● Nexus Dashboard Insights downgrade is not supported.
● When the Device Connector is unclaimed from the on-premise GUI application, the Device Connector must be unclaimed from Intersight for TAC Assit’s connected TAC functionality to work.
● After modifying a bridge domain or VRF instance for an EPG, the flows show errors and flow analytics does not work as expected.
● For virtual Nexus Dashboard (vND), you must provision the underlying HOST with Distributed Virtual Switch and not with a Standard Virtual Switch.
● Nexus Dashboard Insights release 6.0.1 supports Kafka export for Flow anomalies. However, Kafka export is not currently supported for Flow Event anomalies.
