How do I expand a subnet/VLAN in DNA Center?

[mjohnson3150]

Hello,

I have a subnet/VLAN in DNA Center version 2.3.3.5 that I need to expand from a /24 to a /22. I'm not finding a procedure on how to do this. From what little I know about it, I'll need to delete the existing VLAN and create a new one with the /22 but when I do that, DNAC will create a new VLAN number in the process. At that point, I would need to deploy this out to all of our switches. Does anyone have a solid procedure on how to do all of this? Thank you.

Hello, if the question relates to an SD-Access Fabric, then you're correct, you need to delete the old subnet and create a new one. During the creation process you can nominate the VLAN name and number to match the deleted ones, if you wish. In SD-Access UI, under the question mark menu in the top right corner, there is a "Make a Wish" button, which you can use to provide feedback to the product owners. You could use that to suggest/request SD-Access different capabilities if you like. Regards, Jerome
