Network Device Health Summary UI Enhancement - Unmonitored to No Health |
The Network Device Health Summary - Total Devices section provides the total number of network devices and the count of Good Health, Fair Health, Poor Health, and No Health data. |
Cisco SD-Access: Network Health Dashboard Enhancements |
The Network Health Summary dashlet provides new KPIs for fabric domains:
In the Network Device dashlet, you can filter the network device table based on the fabric types, including Extended Node. |
Cisco SD-Access: Device 360 Enhancements |
In the Network Device 360 - Device detail area, below the timeline, you can view additional information about the device such as Fabric Role, Fabric Domain, and Fabric Site. In the Detailed Information area under the Fabric tab, new fabric KPIs are grouped under Fabric Infrastructure and VN Service included for device health. |
Cisco SD-Access: Network Topology Enhancements |
In the Physical Neighbor Topology for fabric domains, the fabric badge icons identify device fabric groups such as Border, Control Plane, Edge, Extended Node and Wireless. |
Event Viewer Enhancements |
In the Client 360 Dashboard, the Event Viewer detailed information area is enhanced to show:
|
WAN Link Utilization Dashlet |
You can view the status of the WAN link utilization percentage only for the available WAN links in your network. |
WAN Link Availability Dashlet |
You can view the status of the available WAN links in your network. |
Power Stack Visibility |
In the Network Device 360 view, you can view the stack power connection details under the PoE tab. |
Power over Ethernet Dashboard |
The PoE dashboard is added to Assurance > Dashboards > PoE, which lets you monitor and view the operational state of the PoE-capable devices in your network. The following dashlets are available: PoE Operational State Distribution, PoE Powered Device Distribution, Power Load Distribution, PoE Insights, and PoE Power Usage Dashlet. |
Sensor Test - Proxy |
With this release, proxy support is enabled for Sensor-Driven Tests. You can run the sensor test through proxy settings. |
Application Experience Health Score Calculation Enhancements |
You can add the Application Response Time KPI to the Application Experience health score calculation. See View Application Experience of a Network Device and View Application Experience of a Host. |
Application Health Score Customization |
You can customize the health score calculation for applications by changing the KPI thresholds on a per-traffic class basis and specifying the KPIs that are included for the calculation. |
Monitor Application Health Enhancements |
Click the Managed Clients tab to view only the clients that are managed by Cisco DNA Center. |
View and Manage Issues (Access Point Issues) |
A poor RF issue triggers when APs have a poor wireless experience. The poor RF issue instance second slide-in pane supports Problem Details, Impact Details, Troubleshooting, and Suggested Actions for poor RF issues. Also, the poor RF issue instance second slide-in pane allows you to compare the health of AP radios across the floor in a building. See Access Point Issues. |
View and Manage Issues (Wireless Client Issues) |
With this release, the Cisco DNA Center machine reasoning engine (MRE) supports root cause analysis (RCA) for AAA server issues. RCA allows you to analyze Cisco ISE syslog messages from various servers to derive the possible root causes that could have triggered the issue. RCA support is extended for the following AAA server issues:
|
View and Manage Issues (Radio No Activity Issues) |
The radio no activity issue instance identifies and raises an issue for AP radios that fail to serve clients for 60 to 240 minutes. The radio no activity issue instance pane supports Problem Details, Relevant Issue, and Suggested Actions. See Access Point Issues. |
Monitor and Troubleshoot the Health of a Device |
The Device 360 page now supports a Map and Comparison View that allows you to compare the last 5 minutes of health of AP radios across the floor in a building. |
Baselines Dashboard |
Cisco AI Network Analytics uses the most advanced machine learning techniques to define the baseline that is relevant to your specific network and sites. |
MAC Randomization |
With MAC randomization, client devices use unique private MAC Address - RCM Randomized and Changing MAC Address when connecting to the Wi-Fi network. See Monitor and Troubleshoot the Health of All Client Devices. |
Deprecated Feature: Sensor-Driven Tests Using the Legacy Method |
You can no longer create and run sensor-driven tests using the legacy method. You need to create and run sensor-driven tests using templates. |
