Configuration Change

You can monitor and analyze changes to network KPIs due to configuration changes and software changes from the Configuration Change page. Network KPIs can be compared before and after a configuration change is applied to the system, thereby presenting the impact of the configuration changes or software updates on the system and its devices.

Note: Configuration change analysis is only available for SmartZone controllers.

On the Navigation bar, click AI Assurance > Network Assurance > Config Change. The Configuration Change page is displayed.

Configuration Change Page (Upper Portion Only)

The Configuration Change page has the following components:

Configuration Change tile
Configuration Change table
Health tile

The Network Hierarchy filter and Date and Time filter are displayed in the upper-right corner of the Content panel. These option controls the elements displayed within the Content Panel. To modify these options, refer to Content Panel.

Configuration Change Tile

The Configuration Change tile displays configuration changes that have been applied at the Zone, WLAN Group, WLAN, AP Group, and AP levels for the selected time period in the Date and Time filter. Every change in configuration or software change is displayed as a dot on the time series graph. Each dot is colored based on the level on which the configuration was applied and is represented by that color. Each colour dot level is defined on top of the time series graph. Clicking the pointer at any instance on the timeline updates the History tile and Configuration Change table and vice versa. In the time series graph, pause the pointer over a dot to see when the configuration change was applied.

Additionally, there are two scrolling widgets or "lens" that represent a section of time or time slot on the time series graph. They are usually termed "Before" and "After" to indicate the health of the network before and after the configuration change was applied. Scrolling the lenses dynamically computes the KPIs and displays the values on the Health tile.

Note: Health tile data (before, after, and comparison numbers) is impacted by several factors, including system configuration, Wi-Fi environment, type of clients, number of clients, network back haul, and so on. Therefore, if the scrolling widgets move to an area where there is no visible configuration change (a colored dot), Health tile data may still change based on some of the previously mentioned factors.

To determine the network health before and after the firmware update (the orange dot in the figure), scroll the Before lens to a time prior to the firmware update and scroll the After lens to a time after the firmware update. KPIs on the Health tile are computed and displayed immediately, providing clear "before" and "after" values for each KPI. In the Health tile, by default, the Overview tab information is displayed. Select the different tabs from the drop down to view the other tabs information.

Configuration Change Table

The Configuration Change Table is a tabular representation of all the time series data in the Configuration Change tile displaying specific information about what changed after the configuration was applied for the selected time period in the Date and Time filter. It displays information about the timestamp of the configuration change, the entity type for which the configuration was applied (Zone, WLAN, AP, and so on), the entity name, configuration, and information about what specifically changed after the configuration was applied (Change From and Change To columns).

You can select the number of data displayed per page from the drop down at the bottom of the page.

Additionally, you can also filter for relevant configuration changes that are specific to a particular KPI by simply clicking the KPI in the Health tile, or the Add KPI filter above the table.

To apply the KPI filter, click on the Add KPI filter field, select the attributes from the drop down, and click Apply.

Note: When a configuration is disabled, the value of the configuration change appears as 0.

Health Tile

The Health tile displays the same KPIs that are available on the Health page, the difference being the Health tile displays KPI data aggregated over 24 hours, which is more granular than the Health page with respect to time for the selected time period in the Date and Time filter. For more information, refer to Monitoring Wireless Network Health. In the Health tile, you can view the before and after values of each KPI impacted by the configuration change. The overall impact of the change is displayed within a red, gray or green capsule based on the percentage change. The capsule appears green if the configuration change positively impacted the KPI or improved the performance by more than five percent. It appears red if the change negatively impacted the KPI value and diminished the performance by less than five percent. It appears gray if the KPI value is strictly + or - 5%. These granular details enable an administrator to monitor network health continuously and ensure the network performs to its highest capabilities. By default, the Overview KPIs information is displayed. Click Overview field and select the other Health KPIs such as Connection, Performance, and Infrastructure.
