Cisco DNA Center Version 2.3.5 represents a huge step forward in monitoring and automating your network, regardless of where it is in the world.  With the release of the AWS Hosted Virtual Appliance, you can now deploy Cisco DNA Center quickly and easily, and monitor your network, regardless of where your datacenter is located.  Improvements to compliance, APIs, and templates expands your ability to configure your network to your specifications, and ensure that it is performing as expected.

Together with EN Customer Success Specialist Kuba Zabiega, I created the table below to give you a quick overview of some key features of the new recommended release.

Feel free to ask me any Cisco DNA Center Software upgrade question using the blue 'Comment' button at the bottom of this article:

Feature Description How does it compare to previous versions?
Virtual ApplianceThe new virtual appliance lets you deploy Cisco DNA Center securely in an entirely AWS cloud hosted solution in under 90 minutes!

Previously, you had to purchase a physical Cisco DNA Center appliance and install it in your Data Center, which was time-consuming. The install alone would take hours not counting planning and lead times. Now, you can host the virtual appliance immediately in AWS Cloud, only paying hosting costs.

Compliance – Compliance has been expanded to include both network profiles and network settings.  There are also now workflows to automatically remediate identified issues for network profiles, network settings and Application Visibility!

Previously, compliance did not include checking the configuration of your network settings, or your templates.  This meant templates or network settings were not monitored or enforced.  Now the full intent of your configuration is monitored and can be remediated in the event of out-of-band changes.

API Enhancements – New APIs allow you to programmatically perform user management, network setting management, and enhanced wireless troubleshooting. You can now reconfigure and reboot APs via code.

Previously, APIs did not include network settings or credential changes.  Also, they were limited in their ability to troubleshoot network issues.  Now you have expanded support for monitoring, managing, and troubleshooting your entire network programmatically.

Template Hub – The new Template Hub makes it easy to view which network profiles are attached to your templates, as well as seeing how a template may conflict with existing configuration.  In addition, the updated simulator allows you to test templates against a specific network device.

Previously, the template editor gave no visibility of which network profiles or sites a template was applied to. You had to go to network profiles and check them individually.  Now, Template Hub has been completely redesigned and enhanced to give you not only full visibility of profiles & sites, but also enable you to assign them directly from the Template Hub!

 

The Virtual Appliance gives you the ability to deploy a Cisco DNA Center instance within AWS Cloud that has full feature parity with the physical Appliance.  There is no additional cost beyond AWS hosting costs for this virtual appliance!

Compliance has been greatly expanded to include both the network profiles and network settings.  This means that even switching templates are now monitored to ensure your device is configured exactly how you intend it.  New workflows mean that you can easily remediate more compliance violations quickly and easily!

There have been a large number of enhancements made to the APIs, too many for us to get into on this post.  I recommend going to the DevNet API Documentation to view the new API.  The shortlist is that you can now create new Cisco DNA Center users, update your network settings as well as get more detailed information about wireless issues, even reconfigure or reboot AP's if necessary.

The template editor was where you went to create or edit templates.  However, if you needed to attach it to network profiles you'd have to go to the network profile page, if you wanted to see how it would look when deployed on a specific network device you'd have to provision that device.  Now, you can create and manage your templates from within the Template Hub.  The template editor can now warn you of potential conflicts with other configuration automatically, and the template simulator has been updated to allow you to simulate deployment to a specific network device, showing you exactly how it would look when you provision - without having you provision it!

@Gallifrean responding to your previous comment, you shouldn't require Cisco DNA Center version 2.3.5 when studying for a CCNP Enterprise exam.  Unfortunately, I don't have any specific recommendations on which router would best help you study, nor any suggestions on how to set up the C8200 in a home network.

@niroulabhaa in response to your question, if you want to test the functionality of the templates you are writing, I recommend you leverage the simulator tool that is also built into Template Hub it will attempt to generate the configuration including any variables and scripting you have embedded.  This will allow you to test the scripts functionality and ensure it works as you expect it to before deploying it to any devices.

@jlafuent  Can the AWS appliance be hosted/setup in a specific region? 
Is there any limitations with using AWS Private Link / Directconnect?
