Release 6.4.1.45 became available.

New Software Features

Product Impact

Feature

Description

Base Functionality

Panduit integration

Panduit Power Distribution Unit (PDU) Integration in Nexus Dashboard Insights enables you to monitor energy usage and unlock sustainability insights for sites and individual devices connected to a Panduit PDU.

Multi-cluster view

You can consolidate multiple Nexus Dashboard clusters into a single Global View.

Time range selection

You can now select a time range in the Site View.

LACP/PIM/IGMP/IGMP-Snooping, and OSFP protocol support

LACP, PIM, IGMP, IGMP-Snooping, and OSPF protocols for switches are now supported.

New Bug Scan in Analysis Hub

You can now view the active and susceptible bugs affecting your network after the Bug Scan is completed in Analysis Hub.

Real-time telemetry (interfaces, hardware stats and more)

Real Time Visualization (RTEV) feature facilitates real-time event rendering within a user interface (UI) environment.

Ease of Use

Compliance rule description and custom recommendations

You to now add a custom description when a compliance rule is created.

Health resource enhancements in Delta Analysis

Delta Analysis now performs an object delta rather than a count delta. So along with the count, you can now view how many anomalies were cleared, how many are unchanged and how many are new anomalies.

Compliance report new UI

A new user experience for easier visibility of communication and configuration compliance.

Performance and Scalability

Connectivity Analysis improved job times

The time taken by the connectivity analysis jobs in Nexus Dashboard Insights has been reduced.

Large file support for Bug Scan

Support for large files for Bug Scan.

1-node Nexus Dashboard support for Insights

This release supports 1-node physical Nexus Dashboard cluster for Insights.

Increased scalability for NDI co-hosted with NDFC in a 3 node pND cluster (250 switches)

NDI co-hosted with NDFC in a 3 node physical Nexus Dashboard cluster now supports 250 switches.

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. See Nexus Dashboard Deployment Guide.

●     The left navigation menu options Operate and Configure are now merged into Manage menu option.

●   For Panduit PDU integration, you must configure a persistent IP address for PDU collector to stream telemetry information for one or multiple PDUs in your site in Nexus Dashboard.

In Nexus Dashboard, navigate to Admin > System Settings > General > External Service Pools > Add Data Service IP Address to configure the persistent IP address.

For more information on persistent IP address requirements, see Cisco Nexus Dashboard and Services Deployment and Upgrade Guide.

Usage Guidelines and Limitations

This section lists the usage guidelines and limitations for Cisco Nexus Dashboard Insights:

●     Nexus Dashboard Insights downgrade is not supported.

●     After modifying a bridge domain or VRF instance for an EPG, the flow analytics does not work as expected momentarily.

●     In Multi-cluster setup, remote cluster system anomalies are not displayed in the local cluster. You must log in to the remote cluster to view the system anomalies.

●     Nexus Dashboard Insights creates a user in APIC called cisco_SN_NI. This user is used when Nexus Dashboard Insights needs to make any changes or query any information from APIC. In APIC navigate to System > History > Audit Logs tab. Cisco_SN_NI user is displayed in the user column.
