Application Experience aims to provide visibility and insights into the performance of applications. It enables a network administrator to quickly analyze the health of applications present in the network and isolate network issues from application issues, enhancing the end-user’s application experience.

Cisco DNA Center offers application visibility, which gives us a clear look at exactly what applications are passing through the network. AVC-based NetFlow is deployed on the network devices, which uses NBAR2 to identify the applications end-to-end consistently. The NetFlow deployed collects IP traffic information by examining the flow of data entering and exiting the network devices interface.

Based on the telemetry collected using NetFlow, Cisco DNA Center calculates the health score for applications and calculates various stats of every application, such as:

Quantitative Metrics: Usage and Throughput

Qualitative Metrics:  Delay, Jitter, and Packet loss

Additionally, we also get an insight on the dashboard, which shows if the delay/jitter/packet loss is happening on the client, server, or application.

This data can be viewed from a device perspective (Device 360 window), from the user perspective (Client 360 window), or from the application perspective (Application 360 window). If you are looking to enable Application Experience in your Catalyst Center, below are the steps.

Steps to Enable Application Experience:

  1. Install the below Packages in Cisco DNA Center:
    1.  Application Visibility Service
      Go to Systems > Software Management > Select “Application Visibility Service” Package > Install
    2. Application Registry
      Go to Systems > Software Management > Select “Application Registry” Package > Install

Please move to next step if these packages are already enabled on your Cisco DNA Center.

  1. Select Cisco DNA Center as NetFlow collector:
    Go to Design > Network Settings > Telemetry > Application Visibility > Choose “Use Cisco DNA Center as the Netflow Collector” > Save
  1. Enable Application Telemetry for Devices in Inventory:
    Go to Provision > Inventory > Select the Device > Actions > Telemetry > Enable Application Telemetry
  1. Enable CBAR on devices:
    Go to Provision > Application Visibility > select the device > Enable CBAR
  1. Enable NBAR Cloud:
  1. The first step is to register your Cisco DNA Center to Cisco DNA Cloud App:
    Go to https://dna.cisco.com/ > create a new account or Login with CCO > from Main Menu Navigate to Applications and Products > Products > Select the Region > Register.  Add required information and register the product.
    Once you click on Register, an OTP generated will be generated.

    Then go to > DNA Center UI > Systems > Settings > Cloud Authentication > Add OTP > paste the OTP from Cisco DNA Cloud

     ii. Enable NBAR Cloud
         Go to Provision > Application Visibility > Discovered Application > Click on “Configure” under NBAR Cloud.

         From here, Click on Configure > add Client ID*, Client Secret, Organization name > Save
         To get the Client ID and Client Secret, click on the hyperlink “Cisco API Console” from the Configure NBAR Cloud sidebar. 

*KEY is the Client ID here

A note about product naming:
Cisco DNA Center is in the process of being rebranded as Catalyst Center. Users of 2.3.7 will see the Cisco DNA Center name in the product. However, as we continue the rebranding process, customers will see both names used in different collaterals but both names refer to the same product.

Thanks angumber,
But is it possible to share details as of how to create Client ID and Client Secret, I fail to see NBAR app API.

Are you able to clarify on this please

@AigarsK Client ID and Client secret are by default available:

Go to Provision > Application Visibility > Discovered Application > Click on “Configure” under NBAR Cloud

From here Click on Configure > add Client ID, Client Secret, Organization name > Save      

To get the Client ID and Client Secret, click on the hyper link “Cisco API Console” from the Configure NBAR Cloud side bar. This will take you to Cisco API Console, use your login.

**KEY is the Client ID here

Buenas tardes,

Les realizo una consulta, tengo alguna ventaja al configurar en el Dnac Umbrella?, ya está funcionando pero no se encuentra configurado en el Dnac, obtengo mayor información en el monitoreo y la solución de problemas?

Muchas gracias.

Hallo @angumber. Thank you for your information regarding DNA Center (currently Catalyst Center). 

I would like to add some points on that.  

With DNA Assurance, we can Application Visibility and Application Experience. 

Application Visibility refers to getting Information about Application Name and Throughput, and Application Experience refers to getting data about Latency, Jitter and Packet Loss. 

I would like to ask you about some key points. 
In Catalyst Center, we cannot get Application Experience data if we have Cisco Cat9000 Switches deployed. 
We can only get Application Visibility Data which is App-Names and throughput. 

My Question is: 

     - Why can we not get Application Experience Data in Catalyst Center if we have C9000 Switches in Deployment. 

     - Why is it only with Cisco IOS XE Router. 

     - Is there any way we could enable App Experience on C9000 Switches???

     - If not, are you planning to add this feature in future??? There are a lot of deployments with C9000 Switches and Application Experience has to be enabled but cannot be. 
     - What are the technical details for this?

Thank you for your answer. 
A.
