Description |
| Cisco NIR App |
Release version 2.2.2.126 became available. |
| Add Site |
Add a site on Cisco Application Services Engine. Any apps installed on Cisco Application Services Engine can access the added sites. |
| Install Cisco Network Insights Resources Application on Cisco Application Services Engine |
Install the Cisco NIR application on the Cisco Application Services Engine using the GUI. |
| Multiple Site support |
The multiple site and flow configuration enables you to onboard the site from the list of available sites. |
| GUI enhancements |
The GUI enhancements include improved dashboard design, custom dashboards with pinning, in-depth analysis of anomalies, site topology view, and bookmark support for detail view. |
| Anomaly Analytics enhancements |
Analyze resource utilization and create custom comparison charts for statistical, environmental, flows, and resources. The graphical representation of anomalies and time zones on the Site Dashboard. |
| Topology Dashboard (Beta) |
The topology view represents the stitching between the nodes connected to the Cisco ACI site. The Early Access Mode in the Network Insights Setup page lets the user enable beta Network Insights features and enhancements. Once the beta features are enabled they cannot be disabled. |
| Anomaly score and anomaly precedence |
The Top Nodes by Anomalies page summarizes anomalies based on the anomaly score and severity of the anomaly. |
| Multicast protocols PIM, IGMP, and IGMP Snoop |
Support for PIM, IGMP, and IGMP Snoop IPv4 multicast operational and statistical data in the Protocol Statistics tab. |
| Flow Analytics enhancements |
Flow analytics records multiple entries for a flow that are captured at individual record times. A time series plot for flow analytics properties represents the node flows that are recorded in the entire site. |
| Endpoint Analytics |
The Endpoint Analytics provides detailed analytics of endpoints learnt in the site. The anomalies detected as part of endpoint analytics include rapid endpoint moves across nodes, interface, and endpoint groups, and endpoints that do not get learnt back after a node reboot. |
| AppDynamics integration |
AppDynamics provides the required metrics for monitoring, identifying, and analyzing the applications that are instrumented with AppDynamics agents. Cisco NIR provides flow analytics, statistics analytics, and topology view on these metrics to identify anomalies. |
| Dashboard Devices |
The detailed view of the nodes with a graphical representation of top nodes and top resources. |
| Troubleshooting |
Debugging commands for Cisco NIR on Cisco Application Services Engine. |

Usage Guidelines and Limitations
This section lists the usage guidelines and limitations for Cisco NIR:
■ Cisco NIR 2.2.2 App supports Cisco ACI 3-Tier architecture for Software Telemetry.
■ A Cisco APIC cluster must have a minimum of 3 APICs. Cisco NIR is not supported on single APIC.
■ Upgrade from Cisco NIR 2.0.x to Cisco NIR 2.2.2 App is not supported for Cisco NIR installed on Cisco APIC.
■ Upgrade from Cisco NIR 2.2.1 to Cisco NIR 2.2.2 App is not supported for Cisco NIR installed on Cisco Application Services Engine.
■ Upgrade from Cisco NIR 2.2.1 to Cisco NIR 2.2.2 App is supported for Cisco NIR installed on Cisco APIC.
■ Cisco NIR app downgrade is not supported.
■ You have to configure telemetry in the Cisco NIR app to configure for fabric node control.
■ Cisco NIR 2.2.2 installed on Cisco Application Services Engine can be launched only on Cisco Application Services Engine. All Cisco NIR app lifecycle operations such as install, enable, launch, and upgrade are available from the Cisco Application Services Engine GUI. You cannot cross launch the Cisco NIR app from Cisco APIC.
■ When you upgrade fabric policy or upgrade nodes, if there is a connectivity loss between the fabric and the Cisco Application Services Engine cluster, the Cisco NIR app may raise incorrect missing endpoint anomaly.
■ After Cisco Application Services Engine reboot, it is recommended to wait until the following are complete for the Cisco Application Services Engine to restore functionality:
■ The acidiag health state displays healthy.
■ The Cisco Application Services Engine cluster displays green.
■ Interface and Port Channel down anomaly will not be raised when oper-state is down, before Cisco NIR app installation. Anomaly is captured only when the oper-state is up or down, after Cisco NIR app is installed.
■ After modifying a bridge domain or VRF instance for an EPG, the flows show errors and flow analytics does not work as expected.
■ For unknown IP address, the traffic from spine nodes will be dropped and flow records are not generated in Flow Telemetry.
■ Connectivity from Cisco NIR to AppDynamics controller using proxy is not supported.
■ Cisco Nexus 9300-EX platform switches do not support VRF based filtering.They support only bridge domain or subnet filtering of flow telemetry rules. Cisco NIR app gets the flows from the subnet if the subnet is across multiple VRFs.
■ If Fast Link Failover is enabled, -FX2 switches will not report the egress interface information for fabric interfaces facing the spines switches.
