Usage Guidelines and Limitations

This section lists the usage guidelines and limitations for Cisco NI app:

     Cisco NI 5.1(0) app 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.

     You have to configure telemetry in the Cisco NI app to configure for fabric node control.

     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.

     If you are deploying Multi-Site Orchestrator, Nexus Insights, and Network Assurance Engine in the same cluster, you must ensure that Nexus Insights and Network Assurance Engine are installed and enabled first before enabling the Multi-Site Orchestrator application.
