Usage Guidelines and Limitations
This section lists the usage guidelines and limitations for Cisco NI app:
● Cisco NI 5.0(1) app supports Cisco ACI 3-Tier architecture for Software Telemetry and Flow Telemetry.
● Cisco NI 5.0(1) 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.
