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.
