Introduction to SD-Access

This topic is to discuss the following lesson:

Hello Rene,
First, i want to thank you once again for explaining technologies in plain english. This is so much fun reading your posts after all the articles in the internet which poses more confusion.
However i have a question. According to Cisco APIC-EM is end of life (https://www.cisco.com/c/en/us/products/collateral/cloud-systems-management/application-policy-infrastructure-controller-enterprise-module/eos-eol-notice-c51-741252.html) and the replacement product is DNA Center Appliance.


If i understand it right the picture should look like:

Could you please confirm or correct me if i am wrong ?

Thanks again for your great posts.
Oliver

Hello Oliver

Yes, your updated diagram looks correct. It corresponds with the high level description at the following Cisco web site as well:


I will let Rene know to see if he can update this information, or if he has a new lesson planned for this.

Thanks again!

Thank you Oliver, I’m going to fix this!

Also in addition to the above (which isn’t fixed yet :smile: ) could you maybe do a lesson on how SD-Access interoperates with traditional campus networks?

It’s on the ENCOR blueprint.

DNA center seems to do the same thing as Vmanage. SD-ACCESS seems to have a lot of overlap with SD-WAN. Is the difference that you don’t use SD-ACCESS to connect remote sites?

Hello Justin

Yes, these products are very similar as far as what they do. They are indeed products that conform to the Software Defined Infrastructure model where network management is implemented using a centralized Network Management System (NMS). Of course vManage is used for Viptela devices while DNA is used for Cisco.

Both SD-Access and SD-WAN are related in that they are technologies that use software as a method of centralized network management. One deals with the Access layer of a network while the other deals with the WAN. SD-anything is an umbrella term under which both SD-Access and SD-WAN fall under. Just like networking is an umbrella term under which access and WAN networks fall under. It’s the same relation but under different architectures.

So simply put, yes, the difference is that you don’t use SD-access to connect to remote sites, but SD-WAN instead.

I hope this has been helpful!

Same observation here.
