Where are the alarms in Cisco DNA Center?


When working with prospects transitioning their conventional administration to Cisco DNA Center, I typically obtain the query: Where are the alarms?

With greater complexity of the community infrastructure and better calls for from customers, there’s a have to step up the sport with regards to community automation.  The method to community administration is evolving quickly to satisfy this greater demand for automation.  Cisco DNA Center is the Intent-Based platform that may carry the automation of the Campus and Branch to the subsequent degree.

With this in thoughts, Cisco DNA Center Assurance leverages the idea of points to assist determine issues slightly than simply monitoring knowledge. Instead of displaying conventional alarms that may overwhelm the community administrator and supply a giant variety of false positives, Cisco DNA Center receives a considerable amount of data from the community units and it processes this knowledge to attempt to determine issues within the community. I personally see the idea of “issue” as signatures for community or shopper issues.

In the snapshot beneath, we are able to see an inventory of points that had been detected on this specific community. The kind of points varies from system, connectivity, utility, shopper, and others.

Issues Characteristics

In essence, there are three sorts of points: native, AI-driven, and user-defined points. Local points are these which are outlined in Cisco DNA Center and usually use thresholds or parameters additionally outlined in Cisco DNA Center.  AI-Driven Issues are additionally outlined in Cisco DNA Center however are recognized by deviations from predicted baselines. These predicted baselines are calculated robotically utilizing AI-driven applied sciences. Network directors can create customized or user-defined points that match Syslog messages.

Issues have a precedence related, they’ll have an area impression (for instance, a shopper) or international impression and they are often resolved robotically or manually. Optionally, community directors can affiliate points with exterior notifications, for instance, e-mail, Webhooks, Pageduty, and others.

In the snapshot beneath, there’s a pattern of the difficulty catalog. For every concern, we are able to see the completely different attributes equivalent to precedence, decision kind, Global/Local class, and Subscription:

Let’s summarize the attributes related to points:

  • Priority (customizable)
  • Enabled vs disabled (customizable)
  • Global vs native
  • Subscriptions Enablement (customizable)
  • Resolution Type (Manual/Auto)
  • Locally outlined, AI-Driven or user-defined

Some of the attributes are customizable, the choices for personalization rely on every concern. In the snapshot beneath, we present an instance of concern customization:

How to Troubleshoot Issues

To assure a great person expertise, we’d like to have the ability to discover issues. But that’s not sufficient, we additionally want to resolve these issues as quick as doable. When Cisco DNA Center identifies points, it supplies a transparent clarification of the issue coupled with advised actions to assist resolve it sooner. Multiple Cisco DNA Center points additionally use Machine Reasoning Engine (MRE) applied sciences to determine the foundation trigger. What is MRE? MRE is a community automation engine that makes use of synthetic intelligence (AI) to automate complicated community operation workflows. It encapsulates human information and experience into a completely automated inference engine that can assist you carry out complicated root trigger evaluation, and detect points and vulnerabilities. In this context, a machine reasoning engine supplies a workflow that ingests telemetry knowledge and applies reasoning guidelines to assist speed up the decision of an issue.

Check the movies beneath for some examples of concern troubleshooting.

User-Defined Issues

On prime of system points (native and AI-driven), community directors can add their very own custom-made points matching Syslog messages originating from community units. We can customise these points with parameters like a precedence and exterior notifications.

In the snapshot beneath, we present a newly artistic concern that detects “Native VLAN Mismatch”:

Issues detected based on user defined issues
