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 Assist’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 6.0.2 supports Kafka export for Flow anomalies. However, Kafka export is not currently supported for Flow Event anomalies.

●     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.
