Release 6.3.1.15

●     In this release the following features are not available:

◦    Time series selection for Interfaces, Endpoints, Multicast, and L3 neighbors.

◦    A graphical view of top resources.

●     After upgrading to this release, some anomaly rules may be updated or deleted. You can manually add these rules after the upgrade based on the new categories and severity.

●     After upgrading to this release, Export Data configuration will contain newer anomaly and advisory categories replacing older ones.

●     Virtual Nexus Dashboard deployment for NDI release 6.3.1requires a greenfield installation of Nexus Dashboard cluster. Upgrade of virtual Nexus Dashboard cluster to run NDI release 6.3.1is not supported.

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.
