Configurations

About Configurations

Cisco DNA Center platform provides you with Configurations to configure a customized network experience using the following options:

  • Event Settings: Cisco DNA Center platform supports specific Cisco DNA Assurance events (or incidents) that may occur within your network. This means that Cisco DNA Center platform can recognize these events and permits you to configure settings that customize the type, category, and severity under which Cisco DNA Center reports them. Configuring this information in the GUI also permits you to customize the information that Cisco DNA Center sends to an external system, such as ServiceNow (or perhaps to one or more REST endpoints that you can configure).

  • General Settings: You can add or edit REST and ITSM endpoint instances within a single or multiple bundles.


Note

You can also configure various types of destinations to deliver the events from the Cisco DNA Center Platform. Click the Menu icon () and choose System > Settings > External Services > Destinations to access the GUI window to configure a webhook, email, syslog, SNMP trap, or ITSM destination.

Configure Event Settings

A preset number of issues (or events) that may occur within your network can be found in Event Settings in the Configurations window. You can configure the type, category, severity, and workflow of these events.


Note

The Event Settings window functionality is only applicable for an ITSM (ServiceNow) integration and not for generic event notifications. For guidance about how to use this procedure within a larger set of procedures to configure ITSM integration between Cisco DNA Center and ServiceNow, see the Cisco DNA Center ITSM Integration Guide. See the text at the top of this window and click the link (here) to access the Events window in platform, where you can subscribe to events and receive notifications by email, webhook (REST API), SNMP trap, or syslog server.

Procedure

Step 1

Click the menu icon () and choose Platform > Manage > Configurations > Event Settings.

Step 2

Review the Event Settings table that appears.

The following Event Settings information is displayed:

  • Event Name: Name of the Cisco DNA Center event.

  • Workflow: Incident, Problem, Event, or RFC

  • Actions: Edit

You can adjust what is displayed in the table by clicking the Filter icon and using the filter, or by typing a keyword in the Find field. For example, to display all access point notifications, type 'AP' in the Find field. To view all network notifications, type 'Network' in the Find field. To view all severity 1 notifications, type '1' in the Find field.

You can edit the event, so that its notification is customized to your network standards and conventions.

Step 3

Click Edit in the Actions column to edit an event.

Choose a setting by clicking on the downward pointing angle and adjust the value. For example, click Network and adjust to App. This changes the event type from a network type to an application type. Click Severity and adjust to 1 from 5. This raises the severity level from 5 to 1.

Step 4

Click the box next to the event name to enable notifications.

This enables notifications through Cisco DNA Center when the event occurs in the future.
